Power tools are used on materials such as wood, concrete and metal that can produce dust. Personal protective equipment (PPE), dust extraction systems, dust suppression systems and vacuums can be used, as appropriate, to reduce exposure to or inhalation of dust. For recommendations on minimizing exposure to dust, always consult the operator's manual that accompanies your power tool.
The U.S. Occupational Safety & Health Administration ("OSHA") has issued mandatory standards as well as general safety information that address the hazards associated with both combustible and respirable dust.
There are several mandatory OSHA standards that include provisions that address certain aspects of combustible dust hazards. More information on these mandatory standards can be found at: https://www.osha.gov/dsg/combustibledust/standards.html
