Combus­tible dust & NFPA compliance

The standards we build to

NFPA 652 sets the baseline duty — the dust hazard analysis that establishes whether your dust is combustible and what it takes to handle it safely. NFPA 654 governs the system itself for most manufacturing dusts. NFPA 68 covers deflagration venting; NFPA 69 covers explosion prevention and isolation.
