Many everyday materials used in manufacturing processes create dust that, under certain conditions, could result in a catastrophic explosion. Combustible dusts include sugar, flour, wood, cotton, and metals. Even materials not usually considered combustible could burn or explode if dust particles reach a specific concentration.
Consequently, organizations must investigate any activities that create dust to reduce the likelihood of dust-related hazards. In addition to helping to keep workers and property safe, controlling dangerous substances like dust may be necessary for federal and provincial health and safety compliance.
Organizations should consider the following five tips to control combustible dust hazards:
- Understand the risk—Organizations must conduct a thorough risk assessment to determine where dust clouds could form, what could ignite them, and how to minimize the associated risks. They may wish to send a dust sample to a qualified lab to determine its properties and whether it’s explosive.
- Introduce robust cleaning procedures—Ideally, organizations should enclose plants handling fine dust to prevent dust spread. Additionally, organizations must conduct regular cleaning to remove dust using methods that minimize dust clouds: A vacuum system rather than brushes and shovels may be preferred.
- Control sources of ignition—Sparks from hot work can travel significant distances, potentially acting as a source of ignition for dust clouds. Consequently, organizations should consider adopting cold-cutting methods wherever possible and require employees to obtain hot work permits before conducting activities that produce sparks.
- Implement clear workplace policies—Organizations must develop policies, including dust and ignition control programs and fire safety plans.
- Train employees—Organizations must train all employees on combustible dust hazards and safe cleaning methods to help keep the workplace safe.
The airborne dust many manufacturing facilities create is far more than a housekeeping problem. Disturbance of settled particles could potentially result in an explosive dust cloud. As such, organizations must scrutinize the risks stemming from workplace dust and take steps to mitigate the risks.
