The National Fire Protection Association (NFPA) has released a revised 2018 edition of NFPA 30 Flammable and Combustible Liquids Code. This version replaces the prior edition published in 2015. NFPA 30 is referenced in numerous OSHA, emergency prevention and pollution prevention regulatory programs and becomes enforceable under OSHA and many state and local regulations; therefore, new or amended requirements in the revised edition become immediately enforceable requirements. NFPA 30 provides safeguards to reduce the hazards associated with the storage, handling, and use of flammable and combustible liquids.

The NFPA 30 code applies to the storage, handling, and use of flammable and combustible liquids, including waste liquids. It is intended to “reduce the hazard to a degree consistent with reasonable public safety, without undue interference with public convenience and necessity, of operations that require the use of flammable and combustible liquids.” Compliance with the code does not eliminate all hazards in the use of flammable and combustible liquids.
