All concentrations are in percent by weight unless ingredient is a gas. Gas concentrations are in
percent by volume.
Depending on the additives applied to the treating solution, this wood may also contain <1%
of mold inhibitors, <1% of a non-hazardous oil emulsion, and <1% of a colorant.
Move to fresh air. If breathing is difficult, give oxygen. Get medical attention immediately. Some
species may cause allergic respiratory reactions with asthma-like symptoms in sensitized
individuals.
Remove contaminated clothing. Wash skin thoroughly with soap and water for several minutes.
Prolonged contact with treated wood and/or treated wood dust, especially when freshly treated at
the plant, may cause irritation to the skin. Abrasive handling or rubbing of the treated wood may
increase skin irritation. Some wood species, regardless of treatment, may cause dermatitis or
allergic skin reactions in sensitized individuals. In case of rashes, wounds or other skin disorders:
Seek medical attention and bring along these instructions.
Do not rub eye. Immediately flush eye(s) with plenty of water. Remove any contact lenses and
open eyelids wide apart. If irritation persists get medical attention.
Rinse mouth thoroughly if dust is ingested. Get medical attention if any discomfort continues.
Wood dust: May cause nasal dryness, irritation and mucostasis. Coughing, wheezing, sneezing,
sinusitis and prolonged colds have also been reported. Depending on wood species may cause
respiratory sensitization and/or irritation. Symptoms can include irritation, redness, scratching of
the cornea, and tearing. May cause eczema-like skin disorders (dermatitis). Airborne treated or
untreated wood dust may cause nose, throat, or lung irritation and other respiratory effects.
If one ounce of treated wood dust per 10 lbs. of body weight are ingested, acute arsenic
intoxication is a possibility.
Ensure that medical personnel are aware of the material(s) involved, and take precautions to
protect themselves.
Water fog. Foam. Carbon dioxide (CO2). Dry chemical powder. Apply extinguishing media
carefully to avoid creating airborne dust.
Do not use water jet as an extinguisher, as this will spread the fire.
Explosion hazard: Avoid generating dust; fine dust dispersed in air in sufficient concentrations and
in the presence of an ignition source is a potential dust explosion hazard. Depending on moisture
content, and more importantly, particle diameter and airborne concentration, wood dust in a
contained area may explode in the presence of an ignition source. Wood dust may similarly
deflagrate (combustion without detonation like an explosion) if ignited in an open or loosely
contained area. An airborne concentration of 40 grams (40,000 mg) of dust per cubic meter of air
is often used as the LEL for wood dusts. Reference NFPA Standards- 654 and 664 for guidance.
Toxic vapors from wood and preservative may be given off in a fire. Ash will contain free arsenic
and chromium and may be toxic.
Self-contained breathing apparatus and full protective clothing must be worn in case of fire.
In case of fire and/or explosion do not breathe fumes. Move containers from fire area if you can
do so without risk.
Use standard firefighting procedures and consider the hazards of other involved materials.
May form combustible dust concentrations in air.
