Cryogenic Fire Codes and Liquid Nitrogen Freezers

National Fire Protection Association has not put forth any codes that requires liquid nitrogen freezers or non-pressurized liquid nitrogen dewars to be secured to a wall. Each state or locality can pass more stringent codes, as long as the codes are not less relaxed than the established NFPA codes. Be sure to confirm with your local codes/ordinances to find if there are any variations from federal regulations. A good source of valuable information can come from your local fire inspector but remember the following while working with an inspector:

 

  • Make sure the inspector refers to exact ordinance code violations when the citations are issued.
  • Do not be afraid to question violations while working with the inspector
  • You are eligible for a grace period to fix potential violations before any fines are assessed.
