OSHA issues hazcom guidance for combustible dusts (8/3)
Combustible dusts are solids finely ground into fine particles, fibers, chips, chunks or flakes that can cause a fire or explosion when suspended in air under certain conditions. Types of dusts include metal (aluminum and magnesium), wood, plastic or rubber, biosolids, coal, organic (such as flour, sugar and paper, among others), and dusts from certain textiles, according to OSHA.
The document addresses the combustible dust hazards in relation to the Hazard Communication Standard, which is designed to ensure that chemical hazards are evaluated and the information concerning them is transmitted to employers and workers.
“Recent events have shown the devastation of combustible dust explosions resulting in worker loss of life and injuries,” said acting Assistant Secretary of Labor for OSHA Jordan Barab. “This guidance document is a useful resource to prevent potentially catastrophic events.”
