Unusual Fire and Explosion Hazards
Wood dust from sawing, sanding, machining can be explosive depending on particle size and moisture content. Airborne concentrations of 40 grams per cubic meter is often used as the Lower Explosive Limit (LEL) for wood dusts.

Special Protection Data
Respiratory Protection None usually required if dust and formaldehyde concentrations are within acceptable limits. Approved dust/formaldehyde respirator and goggles are recommended when the allowable exposure limits may be exceeded.
Protective Gloves Not Required. Cloth, canvas or leather gloves are recommended.
Eye Protection Goggles or safety glasses are recommended when machining product.
Local Exhaust Provide local exhaust as needed so that exposure limits are met.
Mechanical (General) Provide general ventilation in processing and storage areas as needed so that exposure limits are met.
Special Self-contained breathing apparatus (SCBA) recommended when fighting fire.
Health Hazard Data
Dust Wood dust can irritate eyes and breathing passages. Some wood species may cause skin or respiratory irritation. Contact by susceptible persons may cause allergies.
Formaldehyde These products release low amounts of formaldehyde. Formaldehyde may be irritating to the eyes, nose, throat and skin. It may aggravate existing respiratory problems and cause allergies to susceptible persons. Formaldehyde has been shown to cause cancer in certain laboratory animals at extreme concentrations (14ppm), far above those normally found in the workplace with this product.
