Why am I being warned about potential exposure to wood dust?
What is wood dust?
- Wood dust is generated when machines or tools are used to cut or shape timber and other wood materials. Activities like chipping, sawing, drilling, sanding or woodturning create wood dust.
How does exposure to wood dust occur?
- The cutting, shaping and sanding of wood releases wood dust into the air, where it can be inhaled. Wood dust also settles onto tables, floors and other surfaces. When disturbed, it can become airborne again and can be inhaled. Handling wood dust and materials containing wood dust, such as compost, can also lead to wood dust being inhaled.
How can I reduce my exposure to wood dust?
- Work outside if possible when you are sanding or creating fine wood dust. Wear a dust mask that fits snugly and comfortably.
- If you work often with wood, are a hobbyist, or do home improvement projects with wood:
- Consider installing a dust-collection or air-filtration system in your indoor work space to help capture and remove wood dust at the source.
- Consider using a saw hood or a sanding table that has suction to pull dust particles downward to prevent inhalation, especially if you are sanding wood that is glued, laminated or has synthetic finishes.
- Do not use brooms, blowers, fans or compressed air to move dust.
- Vacuum with a high-efficiency particulate air (HEPA) filter or use a shop vacuum with a HEPA filter if possible.
- Use wet clean-up methods such as wet rags.
- Carefully bag and seal wood dust from vacuum or other dust extraction systems.
- Wash your hands after finishing wood work and before preparing food and eating.
- Change out of clothes that contain wood dust before entering your home, car, and other areas.
