Combustible dust safety is a component of occupational hygiene. Combustible dust is any material made up of distinct particles that has the ability to catch fire and explode when mixed with air. Combustible dust could be from solid organic material, some metals, or some non-metallic inorganic materials. Dusts are created when materials are transported, handled, processed, polished, ground and shaped. Manufacturing facilities that generate dusts are potentially at risk for fire or explosion from the processes in their facility. It is important that the OHS professional understands the limits of their own knowledge, and recognizes when it is necessary to bring in additional expertise.

In order to act as an effective resource in their workplace, the OHS professional should be familiar with:

– Legislation, regulations, guidelines and standards that pertain to combustible dust safety and fire prevention
– How to conduct risk assessments for dust explosion possibilities
– The importance of a good housekeeping and ignition control program
– The importance of worker training requirements, hazard awareness, and reporting procedures
– The implications of combustible dust for emergency planning and response requirements (Fire Safety Plan, Evacuation, First Aid, etc.)
