Alert! Now is the Time to Be in Compliance with NFPA 652
The NFPA (National Fire Protection Association) recently revised its NFPA 652, “Standard on the Fundamentals of Combustible Dust.” While there are several revisions, the most notable update is the new deadline for industrial manufacturers to complete a dust hazard analysis (DHA).
According to the 2019 revised edition of NFPA 652, a DHA must be completed by September 7, 2020. The standard also requires the DHA be reviewed and updated every five years.
A DHA is critical for any industry whose manufacturing processes produce dust. Industries whose dust is most susceptible to explosion are those in the food, rubber, plastic, metal, wood, and chemical industries. According to OSHA (Occupational Safety Health Administration), combustible dusts include those made from food products such as apple, carrot, cocoa powder, cotton, gluten, and/or potato. Carbonaceous dusts such as charcoal, cellulose, cork are also combustible. Chemical dusts such as calcium acetate and dextrin, and metal dusts such as aluminum, magnesium, and zinc are also on the list. Plastic dusts from epoxy and melamine resins are also considered highly probable of producing a dust explosion.
Rom 1980 to 2005, the CSB (U.S. Chemical Safety and Hazard Investigation Board) reported 281 combustible dust incidents that killed 119 workers and injured over 700 others (1). Though safety precautions, education, and mitigation processes have greatly improved, there were still 105 dust explosions during the 11-year span of 2006-2017 (see chart below).

In OSHA’s Combustible Dust National Emphasis Program, two of the most common citations were improper housekeeping, which includes combustible dust accumulation, and improper use of a compressed air hose to blow down combustible dust. These unsafe practices and general lack of maintenance can be hazardous because even a small amount of dust in the wrong area can be combustible.
To be in compliance with OSHA standards and the revised NFPA 652, complete your DHA before the September 2020 deadline to allow sufficient time for the safe and proper removal of your combustible dust.
