- 17. More than 4,900 violations pursuant to combustible dust
- 18. 20% of violations pertain to housekeeping

- 25. The OSHA NEP defines it as “particulate solid that presents a fire or deflagration hazard when suspended in air or some other oxidizing medium over a range of concentrations, regardless of particle size or shape.”www.explosionproof-vacuum.com
- 27. Most solid organic materials, as well as many metals and some nonmetallic inorganic materials, will burn or explode if finely divided and dispersed in sufficient concentrations.www.explosionproof-vacuum.com
- 28. OXYGEN HEAT CONFINEMENT DISPERSION FUEL Dust Explosion Pentagon 5 basic elements needed for an explosion: 1. Fuel to burn (combustible dust) 2. Oxygen to sustain the fire (air) 3. Heat from an ignition source (spark) 4. A high concentration of dust dispersed into the air (deflagration) 5. The dust must be confined within an enclosure or structure. www.explosionproof-vacuum.com
- 29. Secondary Explosions Enclosed conveyor belt with dust build up on inside Primary explosion from motor sparking creates a dust cloud inside enclosure Dust cloud ignites causing much larger secondary explosion www.explosionproof-vacuum.com
- 31. MSDS sheets are a starting point, but most do not address combustability.
- 33. Many states offer consultation through their Department of Labor’s Division of Occupational Safety eg.www.mass.gov/dos
- 34. Private testing labs (Chilworth, Fike, Gexcon)
- 35. OSHA can also provide dust testingwww.explosionproof-vacuum.com
