DESCRIPTION: Particles generated by any manual or mechanical cutting or abrasion process performed on wood.

PHYSICAL DATA:

Boiling Point – N.A. Specific Gravity – Variable (dependent on species & Moisture content)

Vapor Density – N.A. Solubility in H2O (% by Wt.) Insoluble

% Volatiles by Vol. – N.A. Evaporation Rate (Butyl Acetate – 1) N.A.

pH – N.A. Appearance & Odor – Light to dark colored granular solid. Color & odor are dependent on species and time since dust was generated.

• Although OSHA’s Air Contaminants Rule, including OSHA’s Wood Dust PELS, was struck down in AFL-CIO VS OSHA, 965 f. 2^ND 962 (11^TH Cir. 1992), a number of states have incorporated those provisions in their state plans. Additionally, OSHA has announced that it may cited companies under the OSH Act general duty clause under appropriate circumstances for non-compliance with these levels.

HEALTH EFFECTS DATA:

Inhalation of wood dust may cause nasal dryness, irritation and obstruction. Coughing and sneezing, sinusitis and prolonged colds have also been reported. Wood dust can cause eye irritation and/or possible respiratory reactions. Depending upon species, wood dust may cause dermatitis. Prolonged exposure to wood dust has been reported by some observers to be associated with nasal cancer. The international Agency for Research on Cancer (IARC) has classified wood dust as a nasal carcinogen in humans (Group I).

REACTIVITY DATA:

Conditions to Instability:
   Stable under normal conditions.

Incompatibility:
    Avoid Contact with oxidizing agents & drying oils. Avoid open flame as product may ignite at temperatures in excess of 400 degrees Fahrenheit.

Conditions Contributing to Polymerization: N.A.

PRECAUTIONS SAFE HANDLING AND CONTROL MEASURES:

Avoid eye contact, prolonged contact with skin, and prolonged breathing of wood dust in the air.

Avoid contact with oxidizing agents and drying oils.

Avoid open flame.

Provide adequate general and local exhaust ventilation.

Wear goggles or safety glasses. Other protection, such as gloves and approved dust respirators, may be needed depending upon dust conditions.

Avoid creating dust conditions, sweep or vacuum wood dust spills. Dispose in accordance with EPA, RCRA regulations.

EMERGENCY AND FIRST AID PRCEDURES:

Eyes: Flush with water to remove dust particles. If irritation persists, get medical attention.

Skin: If a rash or persistent irritation or dermatitis occur, get medical advice before returning to work where wood dust is present.

Inhalation: Remove to fresh air. If persistent irritation, severe coughing, or breathing difficulties occur, get medical advice before returning to work where wood dust is present.
