3. HAZARDS IDENTIFICATION

Inhalation: Airborne treated or untreated wood dust may cause nose, throat or lung irritation. Various species of
untreated wood dust can elicit allergic respiratory response in sensitized persons.
Eye Contact: Treated or untreated wood dust may cause mechanical irritation.
Skin Contact: Handling wood may result in skin exposure to splinters. Prolonged and/or repeated contact with
treated or untreated wood dust may result in mild irritation. Various species of untreated wood dust can elicit allergic
type skin irritation in sensitized persons.
Ingestion: Not anticipated to occur.
Chronic Wood Dust (treated or untreated) Effects: Wood dust, depending on species, may cause dermatitis on
prolonged, repetitive contact; may cause sensitization and/or irritation.

4. FIRST AID MEASURES

Inhalation: Remove from wood dust exposure. If breathing has stopped administer artificial respiration. Seek
medical aid if symptoms persist.
Eye Contact: Gently flush any particles from the eyes with large amounts of water for at least 15 minutes. DO NOT
RUB THE EYES. Seek medical aid if irritation persists.
Skin Contact: Rinse wood dust off with water. DO NOT RUB. Once the skin is free of the wood dust, wash
thoroughly with soap and water. Seek medical aid if severe irritation develops.
Ingestion: Rinse the victim's mouth out with water. Do not induce vomiting. If symptoms develop, call a physician.

5. FIRE FIGHTING MEASURES

Flash Point NA Lower Explosive Limit NA
Auto-ignition NA Upper Explosive Limit NA

Extinguishing Agents: Not applicable

Fire-Fighting Procedures: Fire from a separate fuel source may be intense enough to cause thermal
decomposition releasing toxic fumes and/or gases. Wear complete fire service protective equipment, including full-
face NIOSH and NFPA 鈥? approved self-containing breathing apparatus.
Fire and Explosion Hazard: High airborne levels of wood dust may burn rapidly in the air when exposed to an
ignition source.

6. ACCIDENTAL RELEASE MEASURES

Spill or Leak Procedures: Not applicable.
Waste Disposal: See Section 13.

7. HANDLING AND STORAGE

Storage Conditions: Protect from physical damage. Maintain good housekeeping.
Caution: DO NOT BURN TREATED WOOD. Do not use pressure treated chips or sawdust as mulch. Whenever
possible, sawing or machining treated or untreated wood should be performed outdoors to avoid accumulations of
airborne wood dust. Wash hands thoroughly before eating, drinking, using tobacco products, and/or using
restrooms.
NOTE: For plywood products only, provide adequate ventilation to reduce the possible buildup of formaldehyde
vapors.

8. EXPOSURE CONTROLS / PERSONAL PROTECTION

Respiratory Protection: None normally required. When sawing or cutting treated or untreated wood, wear a
NIOSH approved N95 or better dust mask.
Eye Protection: Wear safety glasses with side shields or safety goggles when sawing or cutting.
Skin/Foot Protection: Leather or comparable gloves to prevent splinters. Long sleeve shirt, pants and steel toed
shoes when handling treated or untreated wood.
Ventilation: Saw, cut or machine wood outdoors or in well ventilated areas. Ventilation should be sufficient to
maintain inhalation exposures below OSHA PEL for particulates.
Other Protective Equipment: Wear ear plugs or muffs when using power tools.
NOTE: For plywood products only, if Formaldehyde vapor level exceeds OSHA PEL or STEL, then a NIOSH
approved respirator is required.

9. PHYSICAL AND CHEMICAL PROPERTIES

11. TOXICOLOGICAL INFORMATION

Carcinogenicity Data: IARC has classified untreated hardwood and hardwood/softwood mix wood dust as a Group
I human carcinogen. The wood dust classification is based primarily on IARC鈥檚 evaluation of increased risk in the
occurrence of adenocarcinomas of the nasal cavities and paranasal sinuses associated with occupational exposures
to untreated wood dust. NTP has classified all untreated wood dust as a carcinogen.

A human health risk assessment has been conducted in accordance with U.S. Environmental Protection Agency
(EPA) risk assessment guidance in order to evaluate human health risks associated with exposures to Copper Azole
Type B (CA-B) treated wood. Four different scenarios, including occupational (adult builders), resident handler
(adult female), subchronic (child) and chronic (child to adult) residential, and playground (child and teenager) were
evaluated. Exposures evaluated in the risk assessment include incidental ingestion and dermal contact with
dislodgeable residue from the surface of CA-B treated wood and soil impacted with tebuconazole (TEB) and copper,
inhalation of sawdust from CA-B treated wood, and inhalation of re-suspended soil particulate. Non-cancer health
risks are expressed as margin of exposure (MOE), which is a ratio of the no observed effect level (NOEL) or the
lowest observed effect level (LOEL) for a constituent, to an estimated exposure level for the constituent. The
greater the MOE, the less likely that exposure to the constituent will pose a potential health risk. Based on the
evaluation, the lowest MOE of 170 is for incidental ingestion of copper in the soil for the child resident (ages 1-6
years). Based on EPA guidance, an MOE of 10 is the benchmark for this exposure route. Thus, no adverse health
effects are expected. Most of the MOEs calculated in the risk assessment are greater than 1,000, and therefore,
none of the exposures to TEB or copper evaluated pose a potential health risk. Cancer risks were not assessed
because according to EPA, neither TEB nor copper is a known or probable carcinogen.



12. ECOLOGICAL INFORMATION

Copper Azole treated wood leaching studies were conducted for 30.5 days on commodity size products in dynamic
test cylinders using diluent water at nominal temperatures of 5, 15, and 25 degrees C and pH of 5.5, 7.0 and 8.5.
Samples collected on days 1.5, 2.5, 4.5, 7.5, 10.5, 15.5, 22.5, and 30.5 were analyzed for total copper and
tebuconazole (TEB). The treated wood was then leached for an additional 307.6 to 386.8 days in an experimental
pond to confirm long term preservative loss rates. A suite of bioassays were conducted on day 0.5 effluent. Copper
and TEB loss rates declined exponentially with time and appeared to reach steady state losses at the end of about
week 3. Predictive equations describing these loss rates, for use in developing a risk assessment model, were
developed using non-linear regression analysis. Bioassay results indicated that environmental risks associated with
CA-B preserved wood can be evaluated solely on copper predictions and water quality criteria for copper. The TEB
did not add to the toxicity of the effluent. In fact, it appears that the increased dissolved organic carbon associated
with TEB and wood extractives reduced the copper鈥檚 toxicity in the effluent. These studies were conducted at
dilution water flow rates much lower than could be anticipated in open aquatic environments. Dilution factors in very
slow flowing streams or lakes, where current speeds might be as low as 1.0 cm/sec, are 468 times higher than the
flows created in these tests.

Preliminary modeling indicates that a pier sitting on 25 CA-B treated piling in freshwater flowing at a very low current
speed of 2.0cm/sec (typical of many small lakes) would increase the copper concentrations by 0.28 碌g Cu/L at pH
6.5. This suggests that CA-B preserved piling can be used in most surface waters that do not closely approach or
exceed EPA water quality criteria. However, the models will provide a basis for conducting site specific risk
assessments where large volumes of treated wood are proposed for immersion in poorly circulating bodies of water.

13. DISPOSAL CONSIDERATIONS

Disposal Guidance: DO NOT BURN TREATED WOOD. Do not use pressure treated chips or sawdust as mulch.
