Wood Dust Combustibility
This section is provided to help mitigate through education, the potential dangers in using wood, creating sanding and sawdust and then breathing or coming in contact with that dust.

Wood dust is combustible. It will:
• Burn easily when exposed to an open flame or is heated sufficiently.
• Explode when suspended in the air in sufficient quantities and/or it comes in contact with an ignition source
• Ignite through spontaneous combustion if it is mixed with oils.

Wood dust is a potential carcinogen with an increased risk of contracting nasal cancer after repeated and long-term exposure to wood dust.

Wood dust is the medium by which potentially irritant chemicals found in wood can cause allergic dermatitis and respiratory reactions.

Allergic Reaction
Most all woods, cosmetic, as well as imported, contain chemical compounds which some people can find irritating during cutting or sanding. However, the woods themselves are not hazardous, skin contact or inhalation of wood dust can be. As this is the usual means to convey the potentially irritating compounds found in most woods, installers, because of their repeated exposure to sanding and saw dust, need to be aware of the possibility of allergic reaction. Your flooring, once coated with a finish, is basically inert.

This allergic reaction comes in two forms:
• It can be respiratory, cause sneezing and/or breathing problems or
• It can be in the form of a skin irritant causing itching and in rare cases allergic reactions such as painful rashes.

As an individual becomes sensitized to a wood over time these reactions get stronger. In one case, a famous installer, who has been using exotic wood in elaborate pattern work extensively over the last twenty years and had obviously been previously sensitized as a result, experienced serious contact dermatitis and broke out in painful rashes when installing Bolivian Rosewood floor. So it can happen.

In general, preventing measures such as having good dust collection attached to your sanders, wearing long sleeve shirts and hats to avoid skin exposure, and showering after being exposed to dust, will minimize the skin irritant potential. Wearing a good dust respirator will mitigate the respiratory dangers.

However, for those who wish to test their skins allergic reactive potential prior to working with large quantities of dust may perform skin patch test. Take a small quantity of fine dust from the wood being used and place under a round band-aid on the inside of your forearm. Leave in place for 24 hours and then remove. If any serious skin irritation is present, DO NOT proceed. We recommend this test be performed prior to using any woods in quantity and/or in very dusty conditions, which we have noted as having high potential for allergic reaction. On the following page is a chart, which list woods and potential allergic reactions.

Wood dust is also extremely combustible. Keep in a cool dry place away from ignition sources. Avoid creating dust clouds which in turn create severe explosion hazards should it come in contact with an ignition source. For more information, please refer to the OSHA Material Safety Data.

All wood dust can cause respiratory problems. Many types of wood dust can also cause allergic reactions when coming in contact with your skin. The woods listed are known to have a higher degree of risk of reactive problems. Please take precautions such as good ventilation, dust masks, etc., to limit skin contact with the dust to avoid potential problems especially when using woods from the 1st group above.

Section IV: Fire and Explosion Data

Flash Point: N/A
Fire Extinguishing Media: Determined by surrounding fire. Use a water spray to wet down wood dust to reduce likelihood of ignition or dispersion of dust into the air. Remove burned or wet dust to safe open area after fire is out.
Flammable Units (Percent by Volume):
Lower: Variable **White pine flour/dust-ca. 0.035 ox/ft3
Upper: Not available
**Values depend on wood type, particle size, level of moisture in wood, time and rate of heating, etc. (Typically, white pine auto ignition would be at about 390 - 500 degrees F.)
Special Fire Fighting Procedures & Equipment: None
Unusual Explosion and Fire Hazards: Wood dust is a strong to severe explosion hazard if a dust “cloud” contacts an ignition source. Partially burned dust is especially hazardous if dispersed in air. 212 degrees F has been suggested as the upper temperature limit for continuous exposure for wood without risk of ignition (wood dust may require a still lower temperature). For example: white pine flour/dust as a “cloud” in air requires 0.040 J min. energy for ignition and can produce an explosion pressure of 113 psig max.

Incompatibility (Materials to Avoid): Oxidizing agents and drying oils.
Hazardous Polymerization: Thermal-oxidative degradation of wood produces irritating and toxic fumes and gases, including CO, aldehydes and organic acids.
Hazardous Polymerization: _ will occur X will not occur
Conditions to Avoid: Wood dust is extremely combustible. Keep in a cool, dry place away from ignition sources.

Section VI: Health Hazard Information

Effects of Overexposure: Avoid prolonged or repeated breathing of wood dust in air. Repeated exposures (even below 5 mg/m3) to certain wood dusts (see attached list) can produce allergic responses in sensitive individuals. Avoid repeated or prolonged contact with the skin, which will also cause allergic responses. If allergic responses, such as dermatitis, asthma, or bronchitis develop, it may be4 necessary to remove the sensitive worker from further exposure to wood dust (and also to wood based products like turpentine and resin).
Probable Routes of Exposure: Inhalation, skin
Emergency and First Aid Procedures:
Ingestion: N/A
Inhalation: Remove to fresh air.
If persistent irritation, severe coughing, breathing difficulties or rash occur, get medical advice before returning to work with wood dust.
Eye Contact: Flush with water to remove dust particles from the eye.
If irritation persists, get medical attention.
Skin Contact: If a rash, or persistent irritation of dermatitis occurs, get medical advice before returning to work where wood dust is present. If a splinter enters the skin, remove with tweezers.

Section VII: Toxicity Data

Oral: Not Available
Dermal: The chronic effects of skin contact with wood dust are not fully known and may vary from one wood to another.
Inhalation: N/A
Carcinogenicity: Not listed as a carcinogen by IARG, WTP, ACGIH, or OSHA
Other Pertinent Data: Certain species of woods, (see attached list), are known to cause skin, eye and URT irritation along with allergenic responses and asthma. Exposure to wood dust has been statistically associated with nasal cancer in British furniture workers. (CODATA bulletin, November 1978).
