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.
