Wood Dust

Potential health effects

Repeated exposure over many years to uncontrolled wood dust increases the risk of nasal cavity cancer. Inhalation of wood dust may also increase the risk of lung fibrosis (scarring). There are also increased risks of respiratory and skin sensitization from wood dust and resin resulting in asthma and dermatitis respectively. Wood dust has been evaluated by the International Agency for Research on Cancer (IARC) as group 1, carcinogenic to humans. The ACGIH has determined that certain hardwoods are A1 confirmed human carcinogens. OVERVIEW Dust Hazard: Occupational exposure to wood dust from any timber product has been classified as hazardous according to the criteria of the Occupational Safety and Health Administration. Inhalation of excessive amounts of dust may cause temporary upper respiratory irritation and/or congestion, irritation of the eyes and skin or asthma. Repeated inhalation of hard wood dust increases the risk of nasal cancer and may increase the risk of lung fibrosis. Wood dust may be produced from machining, sanding, grinding, breaking or handling the products. Dust and smoke created from cutting and/or burning this product may cause irritation to eyes, skin, and respiratory system. Avoid breathing dust and smoke. Avoid contact with eyes. Drilling, sawing, sanding or machining wood products generates wood dust, a substance known to the State of California to cause cancer. Avoid inhaling wood dust or use a dust mask or other safeguards for personal protection. Gas Hazard: Traces of formaldehyde gas may be released under wood dust heating conditions. In well- ventilated workplaces the concentration of formaldehyde is unlikely to exceed the
