11. Toxicological Information
Wood Dust:
Wood dust (softwood or hardwood): OSHA Hazard Rating = 3.3; moderately toxic with probable oral
lethal dose to humans being 0.5-5 g/kg (about 1 pound for a 70 kg or 150 pound person). Source:
OSHA Regulated Hazardous Substances, Government Institutes, Inc., February 1990.
Wood dust (generated from sawing, sanding or machining the product) may cause nasal dryness,
irritation, coughing and sinusitis. National Toxicology Program (NTP) and The International Agency
for Research on Cancer (IARC) classify wood dust as a human carcinogen (IARC Group 1). This
classification is based primarily on increased risk in the occurrence of adenocarcinomas of the nasal
cavities and paranasal sinuses associated with exposure to wood dust. The evaluation did not find
sufficient evidence to associate cancers of the oropharynx, hypopharynx, lung, lymphatic and
hematopoietic systems, stomach, colon or rectum with exposure to wood dust.
Additional Toxicity Data: See acute and chronic health effects provided in Section 3: Hazard
Identification.
Target Organs: See acute and chronic health effects provided in Section 3: Hazard Identification.
