The Massachusetts Department of Fire Services (DFS) has enacted the Hazardous Materials Processing regulation (527 CMR 33). The code was developed to help prevent the occurrence of incidents like the explosion in Leominster in 2005, the fire and explosion in Danvers in 2006 (see the CSB investigation), and the fire and explosion in Middleton in 2011 (see the OSHA citations) – all involving processes using hazardous materials. This code will REQUIRE many facilities to implement a variation of OSHA’s PSM and EPA’s RMP programs. Unlike PSM and RMP there is no chemical lists and TQ’s, but rather the code defines the types of physical and health hazards a chemical must have to be included in the program and it is VERY BROAD. In other words, there are thousands of chemicals that would be included in this code that do NOT fall under PSM/RMP.
