Happy 7/17!

July 17, 2020 /

Over the past few years, the obscure industry holiday has been catching on. On 7/17 day we celebrate the Ammonia (R717) refrigeration industry and all our colleagues.

Since it’s a fairly new holiday, I’d like to make a suggestion in hopes that it catches on in the industry. The inspiration for this suggestion is from a 19th century swiss philosopher.

“Thankfulness is the beginning of gratitude. Gratitude is the completion of thankfulness. Thankfulness may consist merely of words. Gratitude is shown in acts.” —Henri Frederic Amiel

While it’s fine to celebrate YOU and YOUR success on this day, I’m hoping we can eventually make it common-place to do these two things every year on 7/17.

  • Show gratitude to your mentors
  • Become a mentor

 

Show Gratitude: First, I’d ask that you take some time to reflect on the people that helped you build your career. Those that took time to answer your questions; that gave you tips, criticisms, and guidance. Basically, anyone that went “above and beyond” what they had to do.

Take a few moments to reach out to them and let them know you appreciate how they’ve positively affected your life. Let them know their efforts paid off. Tell them they’re appreciated. Not only will you make them feel better about themselves, you’ll make it more likely they continue putting in that extra time or effort for new people in our industry.

 

Become a Mentor: Look around your workplace, community, church, etc. and find someone who could benefit from your time, thoughts, resources, or just your presence. Resolve to pay back some of the help you received along the way by supporting someone else on their journey. Because in those moments we spend for each other – and not just ‘with’ each other – we are giving a small piece of ourselves. The world need YOU and you will come to find that there is great value in service to others.

“…the only metrics that will truly matter to my life are the individuals whom I have been able to help, one by one, to become better people.” –Clayton M. Christensen

 

To all my Ammonia friends and colleagues: Thank YOU for all that you do. Happy 7/17 Day!

IIAR 4 & IIAR 8 Public Review #2

July 10, 2020 /

The IIAR announced that two standards are up for their second public review. IIAR 4 Installation of Closed-Circuit Ammonia Refrigeration Systems and IIAR 8 Decommissioning of Closed-Circuit Ammonia Refrigeration Systems. 

My IIAR 4 2020 PR2 Comments and Notes

1.3.4 Installations without an AHJ

This section appears to be rewritten for clarity, but it also removes the requirements that “alternative shall be documented in the design documents and provided to the owner and the installer.” This will definitely become a problem down the road when end-users are asked to justify their apparent non-compliance without adequate documentation of the designers engineering rationale.

 

4.2 Supervisor of Installation (Installer Qualifications)

This section has been revised and adds a requirement that Installing Contractors provide documentation to the facility that they have the skills necessary to:

    • Receive, transport, and install refrigeration equipment, piping, and components.
    • Assemble a refrigeration system.
    • Not harm themselves, others, or damage the structure in which the equipment is to be installed

I imagine this will be handled by some sort of “Letter to File” from the contractor.

 

4.5 Welding of Pressure Containing Components (Repeated in 4.6)

This change requires the contractor to provide the Welding Performance Qualification Record (WPQRs) for the past six months rather than the previous requirement that they just verify the welder’s credentials were not expired. This is going to be challenge to contractors. End-users should aggressively soliciit this information if they expect it in a timely fashion.

 

4.8.6 now explicitly requires that insulated pipe be spaced to allow access for inspections / maintenance. This was always a good idea.

 

4.9.1 now requires complete thread engagement rather than “3 exposed threads”

 

6.2.1 removes “reasonably free of rust” and replaces it with “free of pitting.” Internally, you should probably stick with the old requirement.

 

6.3.5 no longer allows valves connecting to atmosphere to be “locked closed” as they must now be capped, plugged or blind flanged. I don’t know of anyone that allowed a valve open to atmosphere to be locked closed without a plug / cap so this isn’t much of a change in the field.

 

IIAR 4 Links

 

My IIAR 8 2020 PR2 Comments and Notes

Note: Please keep in mind that, according to IIAR 1, decommissioning is “The permanent deactivation of a closed-circuit refrigeration system or part thereof.”

4.6 Documentation

This section moved the suggested methods to the appendix where they belong. Well-implemented PSM programs will likely handle all this documentation as a matter-of-course through their existing MOC, PSSR & PHA policies.

 

4.10 Operating Procedures

This change ONLY affects procedures for decontamination, but it removes the requirement that such procedures comply with IIAR 7. Those procedures would still likely be judged under 1910.119(f). Whenever there is some grey area as to whether a procedure falls under 1910.119(f)(1-4) or 1910.119(j) it’s always wise to link back both. My preferred language is something along the lines of “This procedure must be used in conjunction with the equipment SOP which provides Important Safety, Health, Environmental and Equipment Considerations as well as Controls, Instrumentation, Safety Systems, Valve Designations, Operating Limits, Consequences of Deviation, Steps Required to Correct or Avoid Deviation and an Emergency Shutdown procedure.”

 

4.12.2 Training Records

They’ve reworded this section to require a “sign off sheet” to document that people “received” the training rather than using the PSM/RMP language that you document the “means used to verify” that they “understood” the training. IIAR 8 doesn’t over-ride the existing PSM/RMP requirements, so this has little impact.

 

5.2.3.3 removes the prohibition on “fuel burning appliances” and provides some bromides about conducting such work “safely.” Our template program will continue to prohibit this. While there are obviously situations – especially during decommissioning activities – that may warrant their use, we want to ensure that such activities are run through an MOC (or similar administrative control) before their use.

 

5.3.1.1 changes the requirement that you track chemicals to their ultimate disposal to one that you document that they’ve left the facility. This is sensible and welcome.

Digging Yourself Out of a Hole

June 12, 2020 /

(What to do when you are suddenly responsible for years of Process Safety neglect.)

It’s a scene I come across time and time again: a newly assigned PSM/RMP coordinator staring at me with shock as we progress through their Compliance Audit, Process Hazard Analysis, or 5yr Independent Mechanical Integrity Inspection.

“I didn’t know things were this bad!” they’ll say under their breath, once the situation starts to become a little clearer to them. You can imagine them standing at the bottom of a deep, dark hole wondering how they’ll ever make it back to fresh air and bright sunshine they thought was all around them just a few hours ago. For those of you that have read my previous post on the “Stages of PSM Grief,” this is the moment they are breaking past the Denial stage.

It can be heartbreaking to watch the mixture of Anger, Bargaining and Depression, especially if you remember what it felt like to be there yourself.

Often, I will have to re-assure them that this is just the start of the process and the beginning isn’t going to be fun. Sometimes I’ll quote Winston Churchill.

 

 

What’s really important is that we understand there will be a way out if we remain calm and plan intelligently. Unsurprisingly, you need a process to address Process Safety issues. 

So, let’s start planning our escape!  We’re going to move slowly at first, with ever-increasing confidence, and once we get rolling we’re going to start seeing daylight.

Here’s how our progression will look:

  • Assess the situation
  • Prioritize the issues
  • Formulate the plans & assign responsibility
  • Implement, Implement, Implement!

 

Part 1: Assess the situation

Obviously, if you are in the middle of (or have just gone though) an audit or inspection, you’re well on the way! If you are recently assigned to this coordinator role and you don’t have a recent compliance audit, PHA, and MI report, then these are good places to start.

Assessment is really two parts which can share the same ground.

  • Compliance: Where you are in relation to where you need to be.
  • Culture: Where you are in relation to where you want to be.

I can’t stress this enough – being compliant is not some lofty place. It is the bare minimum of safety allowed under the law. How far past “my company isn’t violating federal and state law” you want to go depends a lot on the culture of your organization. For example, companies with a brand to protect tend to aim a lot higher than those that don’t. Companies that are barely making ends meet tend not to have a lot of resources to bring to bear on things that aren’t strictly required.

Recently, based on a conversation with colleagues, I half-jokingly formulated what I called the Haywood / Chapin Process Safety performance scale as a visual tool. Note that you get a score of zero for being compliant because that’s the baseline. We’re not going to go around congratulating each other for not violating Federal and State laws. Additionally, we aren’t going to give ourselves any credit for trying – only for results: Safety & compliance aren’t kindergarten so we aren’t giving out participation trophies.

Note: It’s common at this point to try and figure out how the company got themselves in this hole, but there is usually very little of value that comes out of this conversation. If the same people, and the same processes are in place, don’t expect different results unless they are willing to change. Don’t get your hopes up just because people want to change. What matters is if they are willing to put in the work to change. If only wanting to change was enough to effect change, nobody (including me) would be carrying around a few extra pounds.

 

Part 2: Prioritize the issues

All right. Now you have collected all the deficiencies so you know the ground you need to cover to get where you want to be – or, in our analogy, how far it is to get out of the hole you are in. Now we need to figure out in what order we need address these issues. Hopefully, your audits have given you some guidance here. For example, this is the color code I use for my compliance audits:

Obviously in this scheme, we’d focus our efforts on the red items, then the orange, etc. You will want to prioritize the actions you take based on the risk to your employees, your community and your business. I strive to get the “buy-in” from the audit team during the audit itself so this step is pretty much done for you. However, you may have a lot of findings & recommendations to deal with so further prioritization can be useful.

 

Part 3: Formulate the plans & assign responsibility

Formulating the plan(s) is one of the most difficult parts of the whole endeavor: How do we address all the issues we’ve found? We’re going to use a few strategies to help us formulate our plan:

  1. Group where appropriate
  2. Don’t reinvent the wheel
  3. Don’t make Perfect the enemy of the Good
  4. Leverage strengths & Avoid weaknesses

Grouping: One thing you may find is that a common root cause means you can group items. For example, if I have a poorly constructed MI inspection with 600 pipe label recommendations I can view each of those as individual recommendations or I can decide that the root cause is that we don’t have a system to ensure adequate pipe labeling. For me, I’d rather put a system in place to address that widespread deficiency than rely on just fixing the issues someone else found thus ensuring I’ll need them to find them next time too! For the example of pipe labeling, I would train my operating staff on the requirements of IIAR B114 and place a label check in the annual unit inspection work order. Properly implemented that system ensures that the issue will be addressed in the next year and will continue to be addressed regularly thereafter.

Don’t reinvent: There’s plenty of freely available templates for nearly all programs, procedures, work orders, etc. you may need. Don’t waste your time creating a policy or procedure from scratch when you can often use a pre-made one to address the issue with little or no change.

Don’t make Perfect the enemy of the Good: Sometimes altering a simple policy that solves the problem 99% of the time to one that solves it 100% of the time turns it into a lengthy and confusing mess. Policies and procedures aren’t meant to completely replace independent thought – they should be designed to guide it. We should bias our efforts towards “good enough” at first and strive towards perfection over time with continuous improvement.

Leverage Strengths & Avoid Weaknesses: Tasks should be assigned to people based on their competencies. For example,  if you have a good core competency in your staff for writing SOPs, then by all means go ahead and write them. But if you don’t have anyone with that experience, maybe outsource that issue so their time is spent on the things they are already good at. Using a stock template and the needed PSI, my personal average for SOPs is about 1.5 hours. I’ve seen relatively competent people take 10 hours or more on the same SOP. The difference is that I wrote the template and have used it thousands of times. On the other hand, I’ve been known to take 3x as long as a skilled operator to change oil filters on a compressor because I’ve only done it a handful of times.

Assigning Responsibility is crucial. What we want is to have someone own the solution. Even if you assign a task to an outside consultant or contractor, make sure someone in-house is assigned the responsibility for the task to ensure they keep that 3rd party in-line and on-schedule.

Also keep in mind that this is a great place in this process to manage expectations. Often a facility has been neglecting their PSM duties for decades but seems shocked that the newly assigned PSM coordinator can’t solve the problem in a few weeks. Let’s just say that if it took 10 years to dig the hole, it’s not realistic to expect anyone to dig you out of it quickly.

 

Part 4: Implement, Implement, Implement!

Prussian military commander Helmuth van Moltke is famous for saying that “No plan survives first contact with the enemy.” You are never going to get anywhere until you go out there and start implementing your plans. You can’t build a reputation on what you plan to do. 

Don’t be hesitant to reassess and change the plan if things aren’t going well.

One of the most important things you can do during this part of the process is having regular PSM meetings. Make sure everyone assigned a task is asked about their progress. It may seem like a waste of time, but it’s also a good practice to go over the things you have already accomplished. I recommend this for two reasons:

  • It gives everyone a chance to confirm that the implemented solution to the issue worked
  • It reminds you that progress is being made and you will eventually get out of the hole if you keep on!

 

 

As always, if there is anything we can do to help, please contact us!

How Many Operators do we Need?

May 22, 2020 /

Disclaimer: This post is a collaboration between an industry friend and colleague, Victor Dearman and I. The views expressed here do not necessarily represent the opinions of any entity whatsoever which we have been, are now, or will be affiliated.

It’s a question we hear often – sometimes as part of a PHA or Compliance Audit, but more often with someone just struggling to justify their staffing requests. Unfortunately, there really isn’t a simple, definitive answer to the question. No controlling RAGAGEP exists and state / local laws on the topic are relatively rare. This sort of problem isn’t rare in PSM because it is a performance-based standard. Our performance basis is that we are staffed sufficiently to ensure the safety of the people within the building and the surrounding community.

We need to answer the “How many Operators do we need?” question in a way that we can support it, or as we like to say, “Build a defensible case for the answer we arrive at. The answer itself will depend on many, many factors. So, let’s go on a journey and see how we can arrive at an answer we can feel confident in.

 

The road to an answer

The biggest factor for many is the design (age!?) of the system controls. A modern system with advanced controls requires less oversight on a day-to-day basis. If your system still relies on manual controls and people writing down pressures every hour, then that’s going to have a significant impact on your staffing needs. But once we get past that obvious issue, things get a bit more complicated.

Let’s be honest here, if things are running well; you have a good history with compliance audits, inspections, incident investigations, etc. and a low MI backlog, you’re probably not asking this question. If you are asking this question, it is probably due to an event related to a PSM/RMP element.

Let’s look at the kinds of element events that typically lead to this question.

  • Employee Participation
  • Mechanical Integrity
  • Incident Investigations
  • Management of Change / Pre-Startup Safety Review
  • Process Hazard Analysis
  • Emergency Action and Response Plans

 

Employee Participation: Look, everyone feels over-burdened at work, especially in the modern “Do MORE with LESS” era. But, if you pay attention to it, and look at these other elements, this employee feedback can provide valuable insights into the adequacy of your staffing.

 

Mechanical Integrity: What we’re looking for here is to understand if you have the skill sets and staffing to adequately maintain your refrigeration system. Whether you do everything in-house, or have a small in-house small crew performing basic rounds and contract out all the rest of the maintenance, inspections, and tests, is it adequate?

Here’s some MI related questions you might ask to help you determine if your staffing is adequate:

    • Are we properly implementing our Line & Equipment Opening (sometimes known as line break) procedures?
    • Are we caught up on ITPMR’s (Inspection, Test and Preventative Maintenance Reports) or work orders?
    • Is the documentation of ITPMR’s, Work orders, Oil Logs adequate?
    • Are we performing our scheduled walk-through’s and documenting them properly?
    • Are we addressing MI recommendations in a timely manner?
    • Are there indications that maintenance of the facility and system are being conducted properly and required repairs aren’t being delayed?
    • Are there no indications in the written MI records, or in your observations, that the system is running outside the written operating limits?

 

Incident Investigations: A review of incident investigation history can tell us a lot if the facility has a good process safety culture. But if they don’t have the right culture, and /or they don’t have any documented incidents, you’re going to have to do a little detective work and interview plant employees to find out if incidents are occurring that aren’t being recorded. Remember to spread your net wide here because incidents can happen at any time, not just on day-shift: Backshifts, weekends, holidays, etc. there’s no time immune to a possible incident.

You may also find indications of incidents occurring in walk-through logs, communications logs, ITPMRs, work orders, etc.

Here’s some II related questions you might ask to help you determine if your staffing is adequate:

    • Are incidents being reported, conducted, and documented? If not, is this a culture issue or a staffing issue?
    • Are incidents and incident report findings & recommendations being addressed, communicated, and followed to their conclusion?
    • Are there incidents that could have avoided with proper staffing?
    • Are there incidents that would have their severity reduced with proper staffing?
    • Are there incident investigations with recommendations that could be addressed with proper staffing?

 

Management of Change / Pre-Startup Safety Review: Properly implementing the MOC and PSSR elements takes a lot of time! We often find that these two elements are amongst the first to “fall behind” in suboptimal staffing situations. Here’s some MOC/PSSR related questions you might ask to help you determine if your staffing is adequate:

    • Have MOCs / PSSRs been conducted when they were supposed to be?
    • Were the MOCs / PSSRs conducted adequately to properly manage the hazards related to the change and the new systems?
    • Is the documentation of MOCs / PSSRs complete?
    • Are there any open items or recommendations from MOCs, PSSRs, or project punch lists?

 

Process Hazard Analysis: The PHA and open PHA recommendations can also help us understand if our staffing levels are appropriate. There may also be indications in the PHA itself. There’s a portion of the PHA that deals with staffing directly, but we’ll deal with that in the Building a defensible case on staffing section of this article.

Here’s some PHA related questions you might ask to help you determine if your staffing is adequate:

    • Are the PHA recommendations being addressed, communicated, and followed to their conclusion?
    • Is the facility provided with modern controls, alarm systems and equipment? (Newer, modern facilities often have significantly lower staffing needs than older ones)
    • Has the PHA been updated / validated as required by MOC activities and the 5yr schedule?

 

Emergency Action and Response Plans: Whether we’re looking at the plan(s) themselves, or analyzing an after-action report, a there can be a lot to learn here concerning proper staffing levels. Obviously, the required staffing levels for Emergency Response facilities is going to be higher, but that doesn’t mean there is no staffing requirement for Emergency Action plans.

Here’s some EAP/ERP related questions you might ask to help you determine if your staffing is adequate:

    • In the event of an incidental release of ammonia, do you have adequate staffing to investigate and respond?
    • In the event of an emergency response, even if you are not a “responding” facility, do you have adequate staffing to ensure that the equipment is properly shut down?
    • If you are a “responding” facility, do you have enough adequately trained personnel to staff your response team including an Incident Commander, safety officer, decontamination personnel, two entry teams, etc.
    • If you bring key staff back on-site to deal with emergencies, are they close enough to respond in a timely manner, or do you need to increase the size of your trained response team?

 

Building a defensible case on staffing

Ok, we’ve answered our questions and gathered a good impression of where we stand – and where we should stand. Maybe we need to adjust our staffing levels and/or increase the amount of services we ask contractors to complete for us. Where should we document this? In our opinion, the place in the system where the facility already had the opportunity to address this issue, was in the PHA. So, let’s go back to the PHA, end see if our results match the PHA team’s.

You are going to be looking for the following two questions (or their equivalents) from the standard Human Factors section of the IIAR What-If /Checklist worksheets:

HF14.37 – What if an employee is stressed due to shift work and overtime schedules?

HF14.38 – What if there are not sufficient employees to properly operate the system and respond to system upsets?

During the PHA, the facility should have answered those in a way that says they have adequate staffing or recommended that staffing be increased. Let’s say you decided that you had adequate staffing based on your answers to the questions above. If that’s the case, we’d expect to see something like the following:

 

If, however, we found some areas for improvement, we might expect something like this:

 

Closing Thoughts: We hope you didn’t start reading this hoping for an easy answer, but we’re fairly certain – now that you understand the full scope of the question being asked – that the answer doesn’t need to be easy, it needs to be correct and defensible.

You can build a much better understanding of your staffing needs by looking at the existing elements in your Process Safety program. Any decent Compliance Audit would cover this same ground, if staffing is an area of concern for you, make sure to bring it up.

—

P.S.  from Victor: Some facilities might try and get more value from a security guard on off shifts or holiday coverage to make roving patrols and report abnormal conditions and alarms? Sure, but that also means that guard has to be trained to identify what the alarms mean, how to identify an abnormal condition, and that they know what to do to either immediately correct the deviation or immediately contact someone that can (on call techs or service providers). By the time you have invested this much into a guard, you could have paid for a well-qualified operator.

My advice to any organization when making these decisions is to evaluate the above and take into consideration the attracting well rounded operators with the skill sets and experience often sought is more often through word of mouth about how the organization projects their Process Safety culture.

How to hire operators? Well, that sounds like a good subject for a future article!

What is the best way to train my ammonia refrigeration operators?

May 15, 2020 /

Nearly 3 years ago we posted an answer to the question “What training does my refrigeration operator need?”

In our experience, to get a good understanding of the Overview of ammonia refrigeration – the fundamentals of how it works – facility provided one-on-one hands-on training is the most effective training approach. This is the approach used for the vast majority of the skilled trades and it is proven effective. Unfortunately, if you don’t already have in-house expertise, there’s nobody to provide the training! A facility lacking on-site talent to act as trainers is when 3rd party providers can provide some value.

We’ve been getting a lot of questions lately centered around getting the best “bang for your buck” when using outside training providers. This post is solely about operator training. That is, the training we need to provide for our refrigeration operators that can be done by outside training providers – Process Safety training will be addressed briefly at the end.

If you don’t already understand that the training these providers offer is usually only going to address a small portion of the overall PSM training requirements, please read “What training does my refrigeration operator need?” before proceeding. I’ll reinforce a key point from that post though: The standard classes offered by most ammonia “schools,” even if they are done properly, only address a portion of the training burden – a small piece of the Overview of the Process requirement. You cannot send your personnel off to some 4-day class and get a qualified operator in return. (Buying a laminating machine doesn’t give you any authority to certify operators, but that’s another post. If you want credentials that matter, go to RETA)

We’re going to answer this question in three parts:

  • What kinds of programs are there?
  • What are the benefits and drawbacks of each training approach?
  • What training approach do we recommend?

 

What kinds of programs are there?

Broadly speaking, the available options break down into three groups:

  1. Self-directed
  2. Instructor based ON-site
  3. Instructor based OFF-site

Self-directed: You give your employee access to refrigeration books (such as the excellent RETA series) and they teach themselves the topic. You might also supplement this with online training which provides feedback and automated testing such as the RETA online training.

Instructor based On-site: Various training providers offer classes taught by an instructor at your facility.  These classes usually run 8-10 hours a day for 3-5 days.  With your approval, the class can use your refrigeration system for any illustration or “hands-on” purposes. If you have enough students, you can make these classes private – meaning only students from your company attend. This allows you to customize the content to reflect your policies. It also allows you to be a little more open about your practices and shortcomings in class discussions.

Instructor based Off-site: Various training providers offer classes taught by an instructor at the training companies “school.” These classes usually run 8-10 hours a day for 3-5 days.  Some of these training providers have built small refrigeration systems (“labs”) that they use to illustrate concepts during “hands-on” sessions. Like the on-site classes, if you have enough students, you can make these classes private.

 

What are the benefits and drawbacks of each training approach?

Program Type Pro Con
Self-directed
  • Lowest cost
  • Flexible scheduling (can be done during low demand times and in off hours)
  • Self-paced
  • Students can pick-and-choose relevant topics and avoid things that don’t apply to your system.
  • Online versions offer good documentation and testing feedback.
  • Bad fit for people that aren’t self-starters
  • Requires above-average reading comprehension skills
  • Questions need to be directed to on-site resources so if you don’t have them, you must reach out to contractors or industry colleagues.
Instructor based ON-site
  • Lower cost compared to Off-site because you avoid lodging, travel, travel time, and most meal expenses.
  • You can set up the class time block for a time convenient to your operations. Many facilities choose to schedule these classes during an off-season.
  • Students are available on-site in case of actual facility emergencies.
  • Instructor-based training can be more responsive and open to questions.
  • “Hands on” and procedural training can be done with your actual equipment and procedures & policies.

 
  • Higher cost compared to self-directed
  • While you can schedule the instruction for any convenient time block, once you have the time locked in, students need to be able to stay in the class during the entire time block.
  • Usually the minimum class size is 8-10 people, so you have to pull a lot of talent into this class or open it up to others. Once you open it up, you also lose the ability to customize the class.
  • There is a tendency to pull students out of the class during the instruction for maintenance “emergencies” more than is actually necessary.
  • Class pace is dictated by the class schedule and tends to move at the pace of the slowest learner in the group. 
  • Many facility’s lack adequate training classrooms. At a minimum, you need a quiet, comfortable space with a projector and screen.
  • Content is usually set, and your students may learn about a lot of equipment and technologies that aren’t applicable to your system. If you are performing a sole-company class, the content can be customized to your needs and equipment, but this may cost extra.
Instructor based OFF-site
  • Students are off-site and can’t be pulled for emergencies.
  • Instructor-based training can be more responsive and open to questions.
  • Most training providers provide clean, comfortable training classrooms.
  • Highest cost when you factor in travel costs, travel time, lodging, meals, etc.
  • You must arrange to meet the schedule of the training provider.
  • Your students are off-site and not available for any facility emergencies.
  • Even though the students are off-site, they will probably be pulled away for endless phone calls and teleconference meetings.
  • Class pace is dictated by the class schedule and tends to move at the pace of the slowest learner in the group. 
  • “Hands on” and procedural training are not done with your equipment and procedures & policies.
  • Content is usually set, and your students may learn about a lot of equipment and technologies that aren’t applicable to your system. If you are performing a sole-company class, the content can be customized to your needs and equipment, but this may cost extra.

 

What training approach do we recommend?

Unless your operators are natural autodidacts (PSM people often prefer learning out of books, for example) self-directed training is not a good fit for most operators. For most organizations, your best bet is instructor-based learning.

As with any training, the more relevant you can make it to your day-to-day operations, the more effective it will be. When you don’t have the on-site expertise to provide training, we think Instructor based ON-site training is the best choice for most organizations. It tends to be more focused on your equipment, procedures & policies and it is more cost effective than off-site training.

One last note: Be extremely mindful of your selection of a 3rd party provider for ANY training, because the instructor’s attitude and knowledge may well affect your safety culture.

PSM-ONLY Note: if you are looking for PSM training – training on how to be a PSM coordinator, or simply to better understand Process Safety systems – then we’d recommend the same as for operator training. But, most organizations don’t have someone sufficiently skilled to provide one-on-one training, so we’re left to seek a 3rd party. Unfortunately, most facilities don’t have enough people for a full class either, so you either need to combine with other facilities in your company (which allows you to have customized training on your policies & procedures) or combine with other organizations to get enough people for an in-house class. Because this is difficult to do, the Instructor based OFF-site option becomes the only one available. While we don’t provide Operator Training, we do offer PSM training.

 

Bonus editorial content: How important is “hands-on” training?

For the purposes of these classes, it is my opinion that the “hands-on” portion of these classes, as it is usually provided, is of little to no value. WHAT!? Allow me to explain:

  • Learning Styles: “But my operators all claim to prefer a ‘hands-on’ learning style!” or “Our operating staff are tactile learners” you say. The idea of learning styles is most likely a “neuromythology” – a popular idea that endures despite having little evidence to support it. In any case, these classes usually don’t really let them “operate” the system in any meaningful way so the “benefit” of “tactile” learning due to “hand-on” training is minimal…
  • “Hands-On”: I used to be an instructor in an organization that provided a lot of classes in the on-site and off-site instructor-based model. The organization provided a lab with “live” ammonia refrigeration systems. Typically, the students spent about a third of their time in this lab, in a group setting. In my opinion, this lab time had very little value for most students. Again, these classes usually don’t really let them “operate” the system in any meaningful way so they are just turning a few valves and conducting exercises in locating valves on PIDs. Certainly, you can manage that level of “hands-on” training at your facility! (I’m sure you can understand why: the liability in letting students operate equipment is HUGE.)

Furthermore, this lab equipment is not the same equipment in your facility, and I can assure you (unless you are woefully non-compliant with General Duty, General Industry standards and PSM/RMP) that their procedures & policies are not YOUR facilities procedures & policies. Most of the benefit that can be gained from “hands-on” training should be done at YOUR facility with YOUR equipment using YOUR procedures and policies. This is how and where the vast majority of your training should actually happen.

Should we perform an Incident Investigation for Hail Damage?

May 6, 2020 /

The Issue: Recently an industry friend reached out with a question that I thought was worth sharing. They recently had some fierce storms roll through their area that involved tennis-ball sized hail. This hail caused some insulation damage, but didn’t cause any ammonia release. Here are some pictures of the type of damage they experienced.

The question is “Would this require an Incident Investigation?”

 

The Law: As always, first we look at the law.

OSHA 29CFR1910.119(m)(1): The employer shall investigate each incident which resulted in, or could reasonably have resulted in a catastrophic release of highly hazardous chemical in the workplace.

EPA 40CFR68.81: The owner or operator shall investigate each incident which resulted in, or could reasonably have resulted in a catastrophic release.

While there is obvious damage to the protective jacketing and vapor barrier, you could make a defensible argument that this is not something that could “reasonably have resulted in a catastrophic release of highly hazardous chemical.” That’s not to say there isn’t any value to such an investigation, but that there most likely is not a requirement to investigate this incident based solely on the PSM/RMP rules. But, the rules aren’t the only guidance available to us, so let’s look further.

 

RAGAGEP and Written Programs: In my opinion, the best RAGAGEP available on the topic is the CCPS book Guidelines for Investigating Chemical Process Incidents, 2nd Edition, which is what inspired the approach we take in our Incident Investigation element Written Plan. Similarly, the IIAR’s publication PSM & RMP Guidelines makes roughly the same types of arguments and include an EPA suggestion that any damage of $50,000 or more should be investigated. If you’ve priced insulation recently, you know we’re likely to hit that threshold.

Here’s the relevant part of our Incident Investigation element Written Plan which incorporates the CCPS guidance:

An Incident is an unusual or unexpected occurrence, which either resulted in, or had the potential to result in:

  • Serious injury to personnel
  • Significant damage to property
  • Adverse environmental impacts
  • A major disruption of process operations

That definition implies three types or levels of incidents:

Accident – An occurrence where property damage, material loss, detrimental environmental impact or human injury occurs. (off-site Ammonia release, product in freezer exposed to ammonia, personnel injury, etc.)

Near Miss – An occurrence when an accident could have happened if the circumstances were slightly different. We sometimes call these incidents “An Accident where something went right”. (Forklift strikes an air unit causing only cosmetic damage and no Ammonia is released, an activation of an automatic shutdown, etc.)

Process Upset / Interruption – An occurrence where the process was interrupted. (Vessel high-level alarm, a nuisance ammonia odor report, ice buildup on an air unit preventing it from cooling properly, failing to conduct required PSM activities as scheduled, etc. Many Process Interruptions are fixed before the event leads to a shutdown. If the equipment was shut down manually or automatically in response to an unexpected occurrence, then the incident is to be investigated as a Near Miss.

This storm damage would seem to trigger the “Significant damage to property” part of the Incident definition and classify it as an Accident due to “property damage.” In accordance with the relevant RAGAGEP and our element Written Plan, we’d expect you to conduct an Incident Investigation despite a defensible argument that the PSM/RMP rules do not require one.

 

What we accomplish with an Incident Investigation: With a formal assessment of the incident, we’re hoping to document the following:

  1. The safeguards in place were adequate such that an ammonia release did not occur;
  2. The damage was investigated and found to be largely cosmetic with no significant effect on integrity, and limited effect on efficiency;
  3. Provide a documented recommendation to address the damage, both in the long term (replacement/repair) and short-term (sealing up any vapor barrier tears with caulking for example);
  4. Provide a method of tracking the identified corrective actions to closure.

Conclusion: While it seems pretty clear the PSM/RMP rules themselves wouldn’t require an Incident Investigation, RAGAGEP would and there’s much to be gained from one.

Powered Industrial Trucks in Machine Rooms

April 10, 2020 /

Powered Industrial Trucks (PIT) in Machine Rooms are a known struck-by hazard.  What most people don’t realize is how serious the results of a PIT impact in a Machinery Room can be.

For example, a forklift / scissor lift impact that shears a 3″ TSS (ThermoSyphon Supply) or HPL (High Pressure Liquid) operating at a typical head pressure of 160PSIG results in a release rate of over 18,500 pounds per minute.

Many facilities attempt to establish a ban on PIT in their machinery rooms, but while the needs for PIT in machine rooms are very limited, there are situations where they are necessary. An outright ban won’t likely survive prolonged contact with reality.

To address this issue in a PHA, we usually recommend a Written Machine Room PIT policy as an administrative control. For years we’ve discussed the content of that policy informally with people. Recently a PSM coordinator shared her written policy & permit with us and after some alterations and formatting, we’re adding it to the SOP Templates section.

Compliance in a time of COVID-19 Pandemic

March 28, 2020 /

The whole country is facing a very difficult situation right now as we all deal with both the COVID-19 disease and the effects of government’s response to it. Some customers (especially restaurant service) are seeing a 2/3rds drop in their business. Other sectors, such as Grocery, are seeing unprecedented demand. Either way, that’s a recipe for chaos.

One of the first cultural victims of chaos is usually the safety / regulatory community. We’re easy to ignore whether the reason is “we’re facing layoffs and bankruptcy” or “orders are up 300% and we don’t have time for this.”

On top of that, in a good-faith effort to re-assure the regulated community that they understand the burdens we’re under right now, the EPA drafted a policy saying they would use discretion on compliance during the pandemic.

That EPA policy was interpreted by some (the environmental lobby mostly) as a blanket waiver of all regulations allowing the regulated community to pollute at will. More significantly worrying to me personally was the calls, emails & texts I started getting Friday where people in our refrigeration community were being “told” this temporary EPA policy was being used to avoid compliance with their PSM / RMP obligations.

With that in mind, let’s look at what it actually says, shall we?

 

What is the EPA actually saying?

Here’s the actual EPA press release. Here’s the actual EPA guidance memorandum. Here’s the important part:

  1. Entities should make every effort to comply with their environmental compliance obligations.
  2. If compliance is not reasonably practicable, facilities with environmental compliance obligations should:
    1. Act responsibly under the circumstances in order to minimize the effects and duration of any noncompliance caused by COVID-19;
    2. Identify the specific nature and dates of the noncompliance;
    3. Identify how COVID-19 was the cause of the noncompliance, and the decisions and actions taken in response, including best efforts to comply and steps taken to come into compliance at the earliest opportunity;
    4. Return to compliance as soon as possible; and
    5. Document the information, action, or condition specified in a. through d

The consequences of the pandemic may constrain the ability of regulated entities to perform routine compliance monitoring,  integrity testing, sampling,  laboratory analysis, training, and reporting or certification. … In general, the EPA does not expect to seek penalties for violations of routine compliance monitoring, integrity testing, sampling, laboratory analysis, training, and reporting or certification obligations in situations where the EPA agrees that COVID-19 was the cause of the noncompliance and the entity provides supporting documentation to the EPA upon request.

 

What does that mean for us in  PSM/RMP covered processes?

Short answer: Not a lot. Long answer follows…

 

Here’s some examples of what it might let you avoid a fine for:

  • Getting an annual compressor vibration analysis a few weeks late because all your contractor’s technicians were ill due to COVID-19
  • Performing a routine MI inspection late because your technicians were ill due to COVID-19.
  • Delaying some training, a compliance audit, PHA revalidation, etc. because of COVID-19 related travel restrictions.

 

Here’s some examples of what it definitely WILL NOT let you avoid a fine for:

  • Starting up equipment without a proper Pre-Startup Safety Review. (If you have time to start it, you have time to check it)
  • Making changes without implementing your written Management of Change policy. (If you have time to change it, you have time to do so safely)
  • Addressing existing recommendations and known problems.
    • If your SOPs have been out of compliance since IIAR 7 was published in 2013, this memo is NOT going to help you avoid fines because COVID-19 doesn’t explain the delay.
    • If your PHA hasn’t been updated to reflect the 2012 IIAR Compliance guidance, this memo is NOT going to help you avoid fines because COVID-19 doesn’t explain the delay.
    • If you haven’t provided documentation that your Operators and/or Contractors are properly trained, this memo is NOT going to help you avoid fines because COVID-19 doesn’t explain the delay.
    • If you have rusted pipes, and have for several years, but you still haven’t gotten around to dealing with them, this memo is NOT going to help you avoid fines because COVID-19 doesn’t explain the delay.
  • Delaying, or failing to report a release of ammonia. It does not affect the requirements to REPORT releases.

Accidental Releases: Nothing in this temporary policy relieves any entity from the responsibility to prevent, respond to, or report accidental releases of oil, hazardous substances, hazardous chemicals, hazardous waste, and other pollutants, as required by federal law, or should be read as a willingness to exercise enforcement discretion in the wake of such a release.

 

Closing thoughts

Unless you are in a very unique position, this EPA memo means very little to you at all. Here’s examples of two clients that it does affect:

  • Scheduled 5yr MI delayed: The client has delayed their scheduled 5yr MI inspection & audit because of travel restrictions in their state. Their intent is to schedule it as soon as it is reasonably safe to do so once this pandemic has passed. If they document how COVID-19 caused this delay, this memo helps them feel confident that the EPA understands the issue.
  • Compliance Audits delayed: The client still has until June to meet their 3yr date but had to delay their scheduled March compliance audits due to travel restrictions. Assuming the issue has passed, and they can reschedule before they hit their June requirement, they have no issue at all. If the issue continues such that they will not be able to complete their 3yr compliance audits before the deadline this EPA policy helps them if:
    1. The audit activities that can be done remotely are done before the 3yr date, and
    2. The audit activities that cannot be done remotely are done as soon as reasonably possible after the pandemic has passed. They will also need to document how COVID-19 caused this delay.

IIAR 2 202x Public Review 1

March 24, 2020 /

The IIAR has released a proposed draft of IIAR 2 Safety Standard for Design of Closed-Circuit Ammonia Refrigeration Systems for public review. Here’s the notice:

March 20th, 2020

To:

IIAR Members

Re:

First (1st) Public Review of Standard BSR/IIAR 2-202x, Safety Standard for Design of Closed-Circuit Ammonia Refrigeration Systems.

A first (1st) public review of draft standard BSR/IIAR 2-202x, Safety Standard for Design of Closed-Circuit Ammonia Refrigeration Systems is now open. The International Institute of Ammonia Refrigeration (IIAR) invites you to make comments on the draft standard. Substantive changes resulting from this public review will also be provided for comment in a future public review if necessary.

BSR/IIAR 2-202x specifies the minimum safety criteria for design of closed-circuit ammonia refrigeration systems. It presupposes that the persons who use the document have a working knowledge of the functionality of ammonia refrigerating system(s) and basic ammonia refrigerating practices and principles. This standard is intended for those who develop, define, implement and/or review the design of ammonia refrigeration systems. This standard shall apply only to closed-circuit refrigeration systems utilizing ammonia as the refrigerant. It is not intended to supplant existing safety codes (e.g., model mechanical or fire codes) where provisions in these may take precedence.

IIAR has designated the revised standard as BSR/IIAR 2-202x. Upon approval by the ANSI Board of Standards Review, the standard will receive a different name that reflects this approval date.

We invite you to participate in the first (1st) public review of BSR/IIAR 2-202x. IIAR will use the American National Standards Institute (ANSI) procedures to develop evidence of consensus among affected parties. ANSI’s role in the revision process is to establish and enforce standards of openness, balance, due process and harmonization with other American and International Standards. IIAR is the ANSI-accredited standards developer for BSR/IIAR 2-202x, and is responsible for the technical content of the standard.

This site includes links to the following attachments:

The 45-day public review period will be from March 20th, 2020 to May 4th, 2020. Comments are due no later than May 4th, 2020.

Thank you for your interest in the public review of BSR/IIAR 2-202x, Safety Standard for Design of Closed-Circuit Ammonia Refrigeration Systems.

There are MANY proposed changes. I’ll include a full list of the proposed changes at the end of the post, but here are some highlights:

  • Requirements for System Signage became a little simpler
  • Ammonia detection requirements have changed
    • Most installations now need two detectors in a machine room
    • Installation & Testing for detectors outside machine rooms now refer to external RAGAGEPs.
    • “Level 1” detection now requires liquid & hot gas shutoff at 150ppm
    • Requires AHJ approval if not installing ammonia detection in “Areas Other than Machinery Rooms”
  • New requirements for permanently installed Hoses and Corrugated Metal Fittings to ensure they meet ISO 10380 or ARPM IP-14

 

It’s important that YOU read these changes and make your voice heard if you have any input on them.

IIAR releases new ANSI/IIAR 9 standard

March 18, 2020 /

What you need to know about the new standard IIAR 9

IIAR 9-2020 has been officially released.

This is a new standard and it will require you to do certain things differently going forward.

 

What is it?

This document is a standard for minimum system safety requirements for existing closed-circuit ammonia refrigeration systems. The safety focus is on persons and property located at or near the premises where the refrigeration systems are located…

This standard provides a method to determine if existing stationary closed-circuit refrigeration systems using ammonia as a refrigerant comply with minimum system safety requirements.

For practical purposes it’s a way to deal with a system designed under an older RAGAGEP that doesn’t necessarily require you to update to the latest version of IIAR 2.

 

What’s the problem it’s solving?

How do you build a defensible case that your system built to an older code or standard is still designed, maintained, inspected, tested, and operating in a safe manner if it doesn’t meet the current code or standard? In PSM I refer to this issue as the d(3)(iii) trap. Here’s the relevant law:

1910.119(d)(3)(iii) For existing equipment designed and constructed in accordance with codes, standards, or practices that are no longer in general use, the employer shall determine and document that the equipment is designed, maintained, inspected, tested, and operating in a safe manner.

The way we traditionally did this is in the PHA where we either recommended the facility upgrade to conform to the latest version of the code or standard, OR has the PHA team build a defensible case that the alternative arrangement in the as-built / existing system was at least as safe as meeting the new code or standard. As you can imagine, this was not an easy thing to do.

 

How does this new standard affect me?

First, if you are already compliant with the current RAGAGEP (such as IIAR 2-2014a) then nothing much changes for you. If you are not compliant with the current IIAR 2 then it provides a different fallback position, because if you meet the requirements in IIAR 9, you now have an ANSI certified RAGAGEP that helps you defend the decision not to update to the current code or standard. Put another way: If your system is designed to IIAR 2-1999, then you might be able to use IIAR 9-2020 as an alternative to compliance with IIAR 2-2014a. 

Put in a flowchart, it looks like this:

Please note: this does not change NEW additions and systems – they are evaluated under current RAGAGEP. 

 

Is there anything else it requires?

The new standard requires an initial evaluation for IIAR 9 compliance within 5 years. It also requires that you re-evaluate that IIAR 9 compliance every 5 years thereafter.

 

How should I comply?

As with all compliance topics, there are lots of ways to get from here to there. I’m going with the EASIEST method which is: incorporate this analysis in your PHA. The requirements for evaluation methodology allow for a semi-quantitative technique for risk-ranking which is what you are already doing if you are using traditional IIAR PHA What-If / Checklist methodology.

To that end, I’ve converted every requirement in IIAR 9-2020 to a Checklist and included that checklist in with the existing PHA checklists for IIAR 2 compliance.

So, the next time you revalidate your PHA, if you use the new PHA templates you will automatically be performing this new required IIAR 9 evaluation. I’ve updated the PHA report template, the PHA worksheets, the PSI RAGAGEP letter templates, and the MI-EL1 to reflect these changes as well. Check the template change-log for details.
