On September 7, 2020, per the National Fire Protection Agency (NFPA) 652: Standard on the Fundamentals of Combustible Dust, facilities are required to complete an initial DHA for their facility. The DHA must be revalidated every five (5) years.
DHAs identify when and where dust explosions and flash fire hazards can exist to assist with evaluating consequences and assessing the level of risk in a facility. DHA’s also evaluate your current hazards and controls.
NFPA requirements to prevent Explosion and Fire are not your only concern! OSHA also has standards when dusts are small enough to enter the lungs. We can assist your compliance efforts with BOTH agencies.
Dust Sampling and Analysis
Various tests are utilized to assess your hazards and compliance, such as: • Go / No-Go Explosion Screening • Maximum explosion pressure (Pmax) • Normalized Maximum Rate of Pressure Rise (Kst) • Minimum Ignition Energy (MIE) • Minimum Ignition Temperature (MIT) • Minimum Explosible Concentration (MEC) • Moisture content • Particle size distribution
