If your facility uses or maintains a highly hazardous chemical in quantities above the threshold limit (often 10,000 pounds or more), then the Process Safety Management regulations apply to you.
Never heard of Process Safety Management? Process Safety Management, or PSM as the program is referred to, is an OSHA Performance Standard, which means that the regulations are not prescriptive. Instead, OSHA allows a facility to set up its program in a way that makes sense for the facility, as long as the program performs satisfactorily, the facility meets the regulatory requirements, and it keeps the highly hazardous materials within their containers.
The PSM regulations are outlined in 29 CFR 1910.119. MIOSHA has adopted these regulations in GI Part 91 and OH Part 591. We aren’t going to lie. There is a lot to digest and understand. But, OSHA provides a lot of useful information on its Process Safety Management webpage. It even published a Process Safety Management for Small Businesses brochure in 2017. You can find the brochure here.
PSM applies to toxic and flammable materials maintained in quantities above the thresholds listed in the standard. The OSHA list of highly hazardous chemicals can be found here. The MIOSHA list and regulations can be found here.
