Here’s one you may have never heard of before. The International Agency for Research on Cancer (IARC) classified wood dusts as human carcinogens, too. One study observed furniture workers and other workers exposed to wood dust were more likely to develop a form of nasal cancer called adenocarcinoma. Hardwood dusts, including beech and oak, pose the highest risk. You can control your exposure to wood dust through well designed ventilation systems and/or respiratory protection. Thankfully, The National Institute for Occupational Safety and Health (NIOSH) in the U.S. developed guidelines for local ventilation systems for different woodworking equipment. Previous studies now show higher exposure levels than the levels seen today. But regardless, be sure to wear a respirator or mask certified to protect you from fine wood dust particles.
