Appearance and Odor: White to light brown or grey particulate after rework. The rework product can have a woody odor. The wood component of these products may consist of alder, aspen, beech, birch, cottonwood, fir, gum, hemlock, hickory, maple, oak, pecan, pine, poplar, spruce, walnut, and/or western red cedar.
Primary Health Hazards: If these products are utilized as received directly from the factory there are no associated health hazards and no need for a Material Safety Data Sheet. When this product is reworked causing dust by: sawing, sanding, drilling, or routing this product:
Primary Route(s) of Exposure:
( ) Ingestion: Dust
(X)Skin: Dust
(X)Inhalation: Dust
Effects On Humans: Exposure to wood dusts can result in eye and skin irritation, dermatitis, respiratory system effects
(including hypersensitivity, asthma, suberosis, granulomatous pneumonitis, or acute airway obstruction), and cancer in humans. Exposure to wood dust can result in the development of contact dermatitis. The primary irritant dermatitis resulting from skin contact with wood dusts consist of erythema, blistering, and sometimes erosion and secondary infections occur. The irritant chemicals are normally found in the outer part of the wood in the sap or bark, and therefore loggers and other workers involved in the initial handling of the wood experience dermatitis. The allergic dermatitis typically results in redness, scaling, and itching, which may become vesicular dermatitis if exposures are repeated. This type of dermatitis often occurs on the hands, face, forearms, eyelids, neck, and genitals, and will sometimes not appear until several years have passed following the exposure, although frequently the signs are apparent within a few days or weeks. The chemicals causing this effect are generally found in the heartwood, and therefore those workers involved in secondary wood processing are affected. Certain wood dusts are also associated with asthma. Acute and chronic respiratory system reactions to exposure can include chronic bronchitis, or chronic airflow limitation associated with asthma. An increased risk of nasal tumors (primarily adenocarcinomas) is associated with exposure to wood dust.
Hardwood dust appears to be the primary substance of concern, although the carcinogenic substances in hardwood are unknown.
Acute Exposure: Acute exposure to wood dusts can result in eye and skin irritation, asthma, erythema, blistering, erosion and secondary infections of the skin, redness, scaling, itching, and vesicular dermatitis.
1

Chronic Exposure: Chronic exposure to wood dusts can result in dermatitis reactions, asthma, pneumonitis, and coughing, wheezing, fever and other signs and symptoms associated with chronic bronchitis. Chronic exposure may also result in nasal cancer.
Carcinogenicity Listing:
(x) IARC Hardwoods Only
(x) NTP Wood Dust Listed in the Tenth Report on Carcinogens
Ingestion: Not applicable under normal use.
Eye Contact: Treat dust in eye as a foreign object. Flush with water to remove dust particles. Get medical help if irritation persists.
Skin Contact: Wood dust of certain species may elicit allergic contact dermatitis in sensitized individuals, as well as mechanical irritation resulting in hives. Get medical help if rash, irritation, or dermatitis occurs.
Skin Absorption: Not known to occur.
Inhalation: Wood dust residing in the nasal passages can contribute to dryness, coughing, sneezing, and upper respiratory irritation. Remove to fresh air. Get medical help if persistent irritation, severe coughing, or breathing difficulty occurs.

Flash Point: N/A
Extinguishing Media: Water, carbon dioxide, sand, dry chemical
Auto ignition Temperature: Varies dependent upon particle size, atmospherics, and other factors. Generally 400-500F or
204 to 260C for wood.
Unusual Fire and Explosion Hazards: An airborne concentration of 40 grams of dust per cubic meter of air is used as the
LEL for wood dust. This material can be explosive under these circumstances. Decomposition of this product will cause
various compounds of nitrogen, and carbon products to be released into the atmosphere. This will reduce the oxygen content of the local atmosphere. Positive pressure SCBA’s should be used in this case.
6.
Spill or Residual Rework Material: Dust generated from sawing, sanding, drilling, or routing this product may be vacuumed or shoveled for recovery or disposal. Avoid dusty conditions and provide good ventilation. A NIOSH approved full-face respirator or half-mask respirator with eye protection should be worn.
Precautions: None
8.
Personal Protective Equipment: Utilize the appropriate NIOSH approved dust/fume respirator for any rework done on this product which could produce particulate in the form of dust. The use of eye protection, gloves, and outerwear to keep the wood dust off of skin as needed.
Ventilation: Utilize non-explosive, point source local exhaust ventilation when rework causing dust is conducted.

NTP lists hardwood dust as a Known Human Carcinogen
IARC establishes hardwood dust as a Group 1 Human Carcinogen, causing Adenocarcinoma of the nasal cavity.
IARC also lists hardwood dust as being associated with pneumoconiosis, a pulmonary restrictive disease and asthma.
No data available at this time.
Dry land disposal of this product is acceptable in most jurisdictions. The rework by-product if containing particulate in the form of dust is considered a hazardous material by the EPA due to its potential for ignitability. In all cases contact the local regulatory agency for proper disposal requirements.
There is no transportation restrictions placed on this product by the US Department of Transportation.
US Environmental Protection Agency (EPA) requirements for emergency planning, reportable quantities of hazardous releases; community right-to-know, and hazardous waste management may change over time. Users are therefore advised to determine whether periodically new information is available.
Emergency Planning Requirements: Wood dust is not subject to the EPA emergency planning requirements under the
Superfund Amendments and Reauthorization Act (SARA) (TITLE III) in 42 USC 11022.
Reportable Quantities For Hazardous Releases: A hazardous substance release is defined by the EPA as any spill, leaking, pumping, pouring, emitting, emptying, discharging, injecting, escaping, leaching, dumping or disposing in the environment (including the abandonment or discarding of contaminated containers)of hazardous substances. In the event of a release that is above the reportable quantity for that chemical, employees are required to notify the proper Federal,
State, and local authorities(40CFR 355.40)
Employers are not required by the emergency release notification provisions in 40 CFR Part 355.40 to notify the National
Response Center of an accidental release of wood dust; there is no reportable quantity for these substances.
Community Right-To-Know Requirements: Employers are not required by the EPA in 40 CFR Part 372.30 to submit a
Toxic Chemical Release Inventory Form (Form R) to the EPA reporting the amount of wood dust emitted or released from
their facility annually.
Hazardous Waste Management Requirements: The EPA considers a waste to be hazardous if it exhibits any of the
following characteristics; ignitability, reactivity, corrosivity, or toxicity as defined in 40 CFR 261.21-261.24. Under The
Resource Conservation and Recover Act (RCRA) (40 USC 6901 et Seq.), EPA has listed many chemical wastes as
hazardous. Although wood dust is not listed specifically as a hazardous waste RCRA, EPA requires employers to treat
3

waste as hazardous if it exhibits any of the characteristics listed above. The US Department of Transportation, EPA, State,
and local regulations should be followed to ensure that removal, transport, and disposal of this substance are conducted in
accordance with existing regulations.
