There have been several explosions in Massachusetts in commercial facilities where a hazardous materials process or processing took place. This regulation was developed as a result of these explosions that affected both the public and public safety officials. The Board of Fire Prevention Regulations began work on this regulation after a 2005 explosion in Leominster. A second large explosion took place in Danvers in 2006, and just prior to the implementation of this regulation, a third explosion took place in Middleton in March 2011.
This new regulation (2012) establishes categories of processes and there is a phased implementation of the permit requirement by category. It also establishes emergency response planning for all facilities and post-incident analysis requirements for larger ones. Please read the Frequently Asked Questions and the Commentary Document for a more detailed explanation of the regulation.
January 1, 2014 Deadline for Category 2 & 3 Processes Permit Applications
The final deadline for the phased-in implementation by category of process and vessel size was January 1, 2014. All first time applications for permits for Category 2 and 3 processes covered by 527 CMR 33.00: Hazardous Material Process or Processing should have been submitted by local companies to fire departments. Category 2 processes involve a vessel containing more than 2.5 gallons but less than or equal to 60 gallons and Category 3 processes involve a vessel containing more than 60 gallons but less than 300 gallons, or have an H occupancy due to the vessel. The deadlines for permits for Category 4 and 5 processes took place in 2013. Please see the revised advisory below as the definitions of Category 2 and 3 processes has been clarified. Fire departments should review facilities in the community to be sure they are aware of the regulation.
