NFPA 652 2016 Standard on the Fundamentals of Combustible Dusts®
NFPA 652 was issued on August 18, 2015, and became effective on September 7, 2015. The standard provides requirements for managing combustible dust fire and explosion hazards. It directs the users to appropriate NFPA industry or commodity-specific standards by establishing a relationship and hierarchy between them. These industry or commodity-specific standards are: NFPA 61, NFPA 484, NFPA 655, NFPA 654, and NFPA 664.
If requirements in an industry or commodity-specific NFPA standard differ from or specifically prohibit the requirement in NFPA 652, requirements in the industry or commodity-specific NFPA standard shall be permitted. If an industry or commodity-specific NFPA standard neither prohibits nor provides a requirement, then the requirement in NFPA 652 shall apply.
