A good article. You could probably add a good bit more information and education to it in the future. We tend to overlook dust and its effects on us. It’s not something we really focus on.
We find many commercial properties and more often in the industrial settings such as production, food processing, manufacturing, auto, assembly, logistics, etc sectors that are pretty dusty. i feel bad for some of the conditions people/employees are exposed to and probably don’t even realize it. I can only imagine working in a place like that with dust accumulation over 10, 15, 30 years. For example, you really don’t think about 30 fork lifts running for 10 hours a day for 30 years, but you can see and smell the rubber. If dust (any type, any color) is noticeable enough, we will document it as a concern in the report. It can get everywhere, Most often we see it on insulation facing, in the rafters, in walls, on top of suspended ceiling tiles, storage/mezzanine platforms, in/on HVAC and duct equipment.
Here is a small list found on Google that may be helpful. You can also google OSHA and NFPA for further articles, guidance, and standards!
Combustible Dusts (Explosion Hazard)
These fine particles can ignite and explode when dispersed in air.
-
Organic Dusts: Flour, sugar, starch, spices, cocoa, grain, wood, paper, soap, dried blood.
-
Agricultural Dusts: Corn, wheat, soybeans.
-
Metal Dusts: Aluminum, magnesium, iron, zinc.
-
Plastic/Rubber Dusts: Resins, polymers, additives, rubber particles.
-
Carbonaceous Dusts: Coal, charcoal, coke, lignite, peat, lampblack.
Hazardous Dusts (Health Hazard)
These cause respiratory illnesses or cancer when inhaled.
-
Silica Dust: Crystalline silica from concrete, rock, sand.
-
Asbestos Dust: Fibers from insulation, construction materials.
-
Metal Dusts: Chromium, nickel, beryllium (can be both combustible and toxic).
-
Chemical Dusts: Pesticides, pharmaceuticals, dyes, sulfur.
-
Mould Spores: From organic materials, can be hazardous.
Key OSHA Focus Areas
-
Hazard Determination: Identifying if a dust is hazardous (chemical/physical properties).
-
Control Measures: Ventilation, housekeeping, enclosing processes, proper PPE.
-
Combustible Dust National Emphasis Program (NEP): Directives for inspecting workplaces with these hazards.
-
NFPA Standards: Guidance from the National Fire Protection Association (like NFPA 654) for preventing explosions.
