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.

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.
