Section IV � Fire and Explosion Hazard Data



Flash Point (Method Used):                             Flammable Limits:

LEL:                                                   UEL:



Extinguishing Media: Dry chemical, carbon dioxide, water spray or foam. For larger fires use water

spray. Fog or foam.



Special Fire Fighting Procedures: Move container from fire area if possible. Do not scatter spilled

material with more water than needed for fire control. Dike fire control water for later disposal. Use

agents suitable for type of surrounding fire. Avoid breathing hazardous vapors, keep upwind.



Unusual Fire and Explosion Hazards: The finely divided wood dust presents a dangerous fire and

explosion hazard when exposed to heat or flame. The larger dust present a moderate to dangerous fire

and explosion hazard when exposed to heat or flame.





Section V � Reactivity Data



Stable or Unstable? Stable under normal temperatures and pressures.

Conditions to Avoid:

Incompatibility (Materials to Avoid): Strong oxidizers: fire and explosion hazard.



Hazardous Decomposition or Byproducts: Thermal decomposition products may include toxic oxides of

carbon.



Hazardous Polymerization May Occur or Will Not Occur? Will Not Occur



Conditions to Avoid: Finely divided dusts may ignite easily. Larger dusts usually require longer exposure

time to heat a flame before ignition occurs.





Section VI � Health Hazard Data



Routes of Entry

 Inhalation: Yes

 Skin: Yes

 Ingestion: Yes

 Eye: Yes



Carcinogenicity:

  NTP: Positive human carcinogen (furniture and cabinet making industry). An excess risk of nasal

adenocarcinoma has been reported in workers in this industry. This excess risk occurs mainly in those

that are exposed to wood dusts.

  IARC Monographs: Positive human carcinogen (furniture and cabinet making industry). An excess risk

of nasal adenocarcinoma has been reported in workers in this industry. This excess risk occurs mainly in

those that are exposed to wood dusts.

  OSHA Regulated:



Health Hazards:



Signs and Symptoms of Exposure:

  Inhalation: Acute exposure, depending upon the species of tree, inhalation of wood dust may cause

symptoms ranging from sneezing, coughing, rhinorrhea, fever, muscular aches and pains, labored

breathing, nasapharyngitis, laryngitis, and bronchitis. The irritation caused by some wood dusts may

cause sinus inflammation and nose bleeds. These symptoms have been attributed to an allergic type

reaction and appear to be very species specific. Pulmonary sensitization to specific species have been

documented. Pneumonitis and extrinsic allergic alveolitis may also occur among individuals that are

susceptible to the wood dust. Studies have shown that the wood dust may cause this condition itself.

There is the possibility that microorganisms inhabiting the wood may also be responsible for causing this

condition in some individuals. Many of the more exotic woods have been reported to cause nausea and

vomiting following inhalation; these woods have also been reported to cause dizziness, giddiness, and

cardiac arrhythmias.

  Skin: Acute exposure � all wood dusts have been implicated in causing irritation. This irritation is the

result of dust particles being trapped in the clothes of the worker and producing abrasions. The chemical

agents may cause contact dermatitis with redness, scaling and itching. Severe cases may progress to

blistering of the skin. The areas that are most often affected are the face, eyelids, hands and forearms.

Splinters from some hardwoods may produce septic wounds that may take an extremely long time to heal.

  Eye: Acute exposure � direct contact with wood dust may cause irritation and inflammation.

Mechanical damage of the cornea may also occur.

  Ingestion: No data available.

Medical Conditions Generally Aggravated by Exposure:



Emergency and First Aid Procedure:

  Inhalation � Remove from exposed area to fresh air immediately. If breathing has stopped, perform

artificial respiration. Keep person warm and at rest. Get medical attention immediately.

  Ingestion � Treat symptomatically and supportively. Get medical attention immediately. If vomiting

occurs, keep head lower than hips to prevent aspiration.

  Eyes � Wash eyes immediately with large amounts of water occasionally lifting upper and lower lids,

until no evidence of chemical remains (approximately 15-20 minutes). Get medical attention

immediately.

  Skin � A thorough cleaning of the body, each day as a minimum, is necessary in the prevention of

adverse reactions to wood dust. Any wound resulting from splinters or abrasions should be cleaned

thoroughly. Splinters should be removed as quickly as possible by qualified medical personnel. If an

infection from a splinter wound occurs, seek prompt medical attention. Remove and wash contaminated

clothing at the end of each day.

Work/Hygiene Practices:

Section IX � Miscellaneous Information

The Eleventh Circuit of the U.S. Court of Appeals vacated the permissible exposure limits that OSHA

issued January 19, 1989. They have ceased enforcement of the 1989 PELs and have reverted to

enforcement of the previous limits.



The section in the federal register entitled Organic Dusts of the August 5, 1993 memorandum give

specifics for the wood dust PEL. Wood dust will be regulated under the classification Particulars Not

Otherwise Regulated (PNOR) and will have a PEL of 15 mg/m3 as an eight hour weighted average.



An explanation of the term Threshold Limit Value (TLV). This is the exposure limit recommended by a

private professional association called the American Conference of Government Industrial Hygienists

(ACGIH). These are recommended only and do not carry the weight of the law. HOWEVER, the Hazard

Communication Standards requires that this TLV as well as the PEL be listed on your MSDS forms. At

present, the TLV for hardwoods is one milligram per cubic meter (1 mg/m3) of air and the TLV for

softwoods is five milligrams per cubic meter (5 mg/m3). Both of these is on the eight hour weighted

average concentration.
