NTP: Per NTP’s Tenth Report of Carcinogens: “Wood dust is known to be a human carcinogen based
on sufficient evidence of carcinogenicity from studies in humans. An association between wood dust
exposure and cancer of the nose has been observed in many case reports, cohort studies, and case-
control studies that specifically addressed nasal cancer. Strong and consistent associations with
cancer of the nasal cavities and paranasal sinuses were observed both in studies of people whose
occupations are associated with wood dust exposure and in studies that directly estimated wood dust
exposure.”
IARC – Group I: Carcinogenic to humans; sufficient evidence of carcinogenicity. This classification is
primarily based on studies showing an association between occupational exposure to wood dust and
adenocarcinoma to the nasal cavities and paranasal sinuses. IARC did not find sufficient evidence of
an association between occupational exposure to wood dust and cancer of the oropharynx,
hypopharynx, lung, lymphatic and hematopoietic systems, stomach, colon or rectum.

¹ In AFL-CIO v. OSHA 965 F. 2d 962 (11
th
Cir. 1992), the court overturned OSHA’s 1989 Air Contaminants Rule, including
the specific PELs for wood dust that OSHA has established at that time. The 1989 PELs were: TWA 5 mg/m³; STEL (15
MIN) – 10mg/m³ (all softwoods and hardwoods, except western cedar); western red cedar: TWA – 2.5 mg/m³.
Wood dust is now officially regulated as an organic dust under the Particulates Not Otherwise Regulated (PNOR) or Inert
or Nuisance Dust categories at PELs noted under the Hazardous Ingredients section of this MSDS. However, a number of
states have incorporated provisions of the 1989 standard in their state plans. Additionally, OSHA has announced that it
may cite companies under the OSH ACT General Duty Clause under appropriate circumstances for non-compliance with
the 1989 PELs.
