Health hazards

The primary health hazard posed by this product is dust inhalation which can cause respiratory system irritation. Contact with skin and eyes can also cause irritation. Prolonged or repeated inhalation of wood dust may cause cancer. FLAMMABILITY: Depending on the moisture content and particulate diameter, wood dust may explode in the presence of an ignition source. An airborne concentration of 40 grams of dust per cubic meter of air is often used as the LEL for wood dusts. OR RISKS FROM EXPOSURE ACUTE: INHALATION: Exposure to wood dust may cause irritation to the moist mucous membranes of the nose, throat, and upper respiratory system. EYE CONTACT: Direct eye contact can cause irritation with redness, tearing and blurred vision. SKIN CONTACT: May cause skin irritation. INGESTION: Ingestion of this product is not a likely route of entry. CHRONIC: Wood dust, depending upon species, may cause dermatitis on prolonged, repetitive contact; may cause respiratory sensitization and/or irritation. IARC classifies wood dust as a carcinogen to humans (Group 1). This classification is based primarily on IARC's evaluation of increased risk in the occurrence of adenocarcinomas of the nasal cavities and paranasal sinuses associated with exposure to wood dust. IARC 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.
