Section 11 – Toxicological Report
Toxicity Data – Currently, there is no toxicological data for this product in purchased form.
Toxicity Hazard Rating for Wood Dust is 3.3 (moderately toxic) based on the National Library of
Medicine’s toxicity rating of 1=none and 6=super toxic. A probable lethal oral dose of wood dust
(human) would be 0.5 to 5.0 g/kg. This would be about ¾ of a pound of wood dust for a 150
pound person.
Carcinogenicity – Wood dust is not considered a potential carcinogen by OSHA. IARC classifies wood
dust as a carcinogen to humans (Group 1). This classification is primarily based on IARC’s
evaluation of increased risk in the occurrences of adenocarcimas of the nasal cavities and
paranasal sinuses associated with exposure to hardwood dust. Wood dust has been listed by
NTP as a known human carcinogen.
Sensitization to the Product –Some individuals can become sensitized to certain wood dusts and
develop allergy-like symptoms upon repeated exposure.
