Learn how to reduce the hazards associated with combustible wood dust in the workplace.

Combustible wood dust refers to the fine, dry wood particles that are a by-product of milling wood. This animated video explains why it's a hazard in sawmills and wood shops, and how it only takes a spark to create a fire or explosion that can cause catastrophic injuries, loss of life, and destruction of buildings. Fortunately, these incidents are preventable.

This educational video is a useful health and safety training tool to help employers and workers identify, manage, and control risks associated with combustible wood dust. It’s designed to be watched in conjunction with training in combustible wood dust hazard recognition and mitigation controls.
