Appropriate engineering
controls
Explosion-proof general and local exhaust ventilation. Good general ventilation (typically 10 air
changes per hour) should be used. Ventilation rates should be matched to conditions. If
applicable, use process enclosures, local exhaust ventilation, or other engineering controls to
maintain airborne levels below recommended exposure limits. If exposure limits have not been
established, maintain airborne levels to an acceptable level.
Individual protection measures, such as personal protective equipment
Eye/face protection
Wear dust-resistant safety goggles with side shields where there is danger of eye contact.
Skin protection
Hand protection
When handling wood, wear leather or fabric gloves.
Other
Wear suitable protective clothing. Use of an impervious apron is recommended.
Respiratory protection
If engineering controls do not maintain airborne concentrations below recommended exposure
limits (where applicable) or to an acceptable level (in countries where exposure limits have not
been established), an approved respirator must be worn. Use a NIOSH–approved respirator if
there is a potential for exposure to dust exceeding exposure limits (See 29 CRF 1910.134,
respiratory protection standard).
Thermal hazards
Wear appropriate thermal protective clothing, when necessary.
General hygiene
considerations
If wood dust contacts the skin, workers should wash the affected areas with soap and water.
Clothing contaminated with wood dust should be removed, and provisions should be made for the
safe removal of the chemical from the clothing. Persons laundering the clothes should be informed
of the hazardous properties of wood dust. A worker who handles wood dust should thoroughly
wash hands, forearms, and face with soap and water before eating, using tobacco products, using
toilet facilities, applying cosmetics, or taking medication. Workers should not eat, drink, use
tobacco products, apply cosmetics, or take medication in areas where wood dust is handled, or
processed.
