What is Combustible Dust?
A combustible-dust hazard occurs when potentially flammable dust particles are suspended in the air in an enclosed location. An explosion can occur when an ignition source, e.g., a spark from electrical equipment or metal-to-metal contact, an open flame, or even static electricity, comes into contact with the dust.
OSHA reports show combustible dust can be produced from a variety of materials, including:
Metal dust (e.g., aluminum, magnesium, zinc, and bronze)
Organic dust (e.g., sugar, flour, paper, soap, and soybean)
Coal and other carbon dust
Plastic and rubber dust
Certain textile materials
Workers in a variety of industries are exposed to combustible-dust hazards. These industries include:
Forest and furniture products
Tire and rubber manufacturing
Coal handling and processing
It’s important to protect workers from potential combustible-dust injury by ensuring they wear proper PPE, including flame resistant clothing. G&K will work with you to develop safety solutions, based upon a worksite assessment, to meet your safety goals.
See OSHA’s reissued and NFPA 654 for more information on combustible dust hazards and regulations.
