### SECTION 4 – FIRE AND EXPLOSION HAZARD

Flash Point Method Upper/Lower Flammable Limi t Auto-ignition Rate of Burn Classification Not Applicable Not Applicable Lower: 40.0 g/m 3 400–500 deg. F Not Available Combustible

Unusual Fire and Explosion Hazards : Wood is combustible, and wood dusts may form explosive mixtures with air in the presence of an ignition source.

Fire Fighting Equipment and Extinguishing Media : Use water to wet down wood to reduce the likelihood of ignition. Remove burned or wet dust to open area after fire is extinguished. Fire fighters should use full protective clothi ng including self-contained breathing apparatu s.



### SECTION 5 – HEALTH HAZARDS AND FIRST AID

WARNING! Wood dust may form an explosive mixture with air, use exhaust ventilation when cutti ng, sawing or grinding in an enclosed area . Wood dust may cause irritation to eyes, skin, and upper respiratory trac t. When cutting, sanding, or gr inding avoid inhalation and wear safety glasses. Handling may cause splinters, use punctu re resistant gloves.

Signs and symptoms of acute ov erexposure First Aid Measures Eyes: Wood dust may cause irritati on to the eyes. Symptoms can include irritation, redness, scratching of the cornea, and tearing Immediately flush eyes with wa ter for at least 15 minutes. Seek medical attention if symptoms persist

Skin: Wood dust may cause irrita tion to the skin. Mechanical rubbing may increase skin irritation. Some wood species and their dusts may contain natur al toxins, which may cause dermatitis or allergic reactions in sensitized individuals. For skin contact flush immedi ately with soap and water,
continue at least 15 minutes. If irritation persists, get medical attention immediately. If wood splinters are injected under the skin, get medical attention immediately. Ingestion: Ingestion of wood dusts is unlikely. If ingestion does occur, slight gastrointestinal irritation may result. Certain species of wood and their dusts may c ontain natural toxins, which
can have adverse effects on humans. If the material is swallowed, get medical attention or advice. Do not induce vomiting.

Inhalation: Wood dust is irritating to the nose throat and lungs. Symptoms may include nasal dryness, deposits or
obstructions in the nasal passages, coughing, sneezing, dryness and soreness of the throat and sinuses, hoarseness, and wheezing. Some species may cause allergic respiratory reactions with asthma-like symptoms in
sensitized individuals. If dusts are inhaled, remove person to fresh air. If symptoms persist, seek medical attention.

### Wood Dust Revised 10/3/2005 Page 2 of 2 Note to Physician : Respiratory ailments and pre-existing skin conditions may be aggravated by exposure to wood dust

Medical Conditions Generally Aggravated by Exposure to Wood Dust : Pre-existing eye, respiratory system and skin conditions.

Chronic Overexposure : Wood dusts may be irritating to the eyes, skin and respirator y tract. Prolonged or repeated inhalation of wood dust may caus e respiratory irritation, recurrent bronchitis, and prolonged colds. Depending on the species of wood, recurrent exposure may ca use allergic skin and respiratory reactions in some individuals.

Carcinogenicity : Prolonged exposure to wood dust by inhalation has been reported to be associated with nasal and paranasal cancer. Wood dust is classified as a carcinogen by ACGI H, NIOSH, and IARC. This classification is based on an increased incidence of nasal and para nasal cancer in people exposed to wood dusts. Carcinogenicity of wood dust: ACGIH – A1 Confirmed Human Carcinogen (related to wood dusts-hard wood; N IOSH – Occupational carcinogen (related to wood dust); IARC -- Monograph 62, 1995 (related to wood dust)(Group 1 (carcinogenic to huma ns)). IARC has listed formaldehyde as a probable human carcinogen.



### SECTION 6 – EXPOSURE CONTROL MEASURES/PERSONAL PROTECTION

Personal Protective Equipment Eyes/Face: Wear Safety glasses with side shields when handling, cutting, sanding, or grinding this material. Use a face shield for processes that may generate excessive dusts and splinters. Skin: Wear puncture resistant work gl oves, such as leather when handling. Respiratory: Respirators must be worn if the ambient conc entration of airborne contaminant s exceeds prescribed exposure limits. Dust masks may be worn to avoid inhalation of nuisance dust. Dust masks are not adequate protection in environments above the occupational exposure limit. Ventilation: Cutting, grinding or sanding should be done outdoors or in a well ventilated area.
