3. Hazard Identification
Physical Appearance and Odor: Particulate solid, light to dark in color. Color and odor depend on the
wood species and age of particles. Particles can be generated by any manual or mechanical cutting
or abrasion process performed on wood.
Primary Health Hazards: The primary health hazard posed by this product is thought to be due to
inhaling wood dust.
Likely Exposure Modes:
Ingestion:
x Skin:
x Inhalation:
x Eye:
Medical Conditions Aggravated: Wood dust may aggravate pre-existing respiratory conditions or
allergies.
Signs and Symptoms of Exposure:
Acute: Wood dust may cause eye irritation. Certain species of wood dust can cause allergic contact
dermatitis in sensitized individuals. If inhaled, wood dust may cause respiratory irritation, nasal
dryness, coughing, sneezing, or wheezing.
Chronic: Wood dust, depending on the species, may cause allergic contact dermatitis and respiratory
sensitization with prolonged, repetitive contact or exposure to elevated dust levels. Prolonged
exposure to wood dust has been reported by some observers to be associated with nasal cancer.
Carcinogenicity:
x NTP: Wood dust, Known Human Carcinogen
x IARC Monographs: Wood Dust, Group 1
OSHA Regulated: Not Listed
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.
Emergency Overview
WARNING! MAY FORM COMBUSTIBLE DUST CONCENTRATIONS IN AIR (DURING PROCESSING).
4. First-Aid Measures
Ingestion: NOT APPLICABLE
Eye Contact: Wood dust may cause mechanical irritation. Treat dust in eye as foreign object. Flush with
water to remove dust particles. Seek medical help if irritation persists.
Skin Contact: Wash with water to remove dust particles. Seek medical advice if a rash, persistent
irritation or dermatitis occurs.
Skin Absorption: NOT APPLICABLE
Inhalation: Wood dust may cause unpleasant obstruction in the nasal passages, resulting in dryness of
nose, dry cough, sneezing and headaches. Remove to fresh air. If persistent irritation, severe
coughing or breathing difficulties occur, seek medical advise.
