SECTION 5. FIRE FIGHTING MEASURES
Flammability of the Product
These wood-based panels are flammable but difficult to ignite.
Auto-ignition Temperature 204 to 260 °C
Flash Point Not available.
Flammable Limits
Higher: undetermined (varies with composition particle size, moisture level, rate of
heating and dust concentration).
Lower: 40 grams/m
3
(LEL) wood dust.
Extinguishing Media
Use water spray, dry chemical or carbon dioxide when fighting fires involving this
material. Dry sand or earth can be used for small fire.
Hazardous Combustion Products
Burning of wood panel produces irritating and toxic emissions, including carbon
dioxide, carbon monoxide, noxious fumes, aldehydes and organic acids.
Special Fire-Fighting
Equipment/Procedure
Firefighters must wear fire resistant protective equipment. Wear self-contained
breathing apparatus with full face piece operated under positive pressure demand
mode.
Fire Hazards in Presence of Various
Substances
There is risk of fire/explosion when high concentrations of fine dust particles come
in contact with a source of ignition as heat or flame.
Explosion Hazards in Presence of
Various Substances
Dust explosion is strongly possible if dust concentrations rise to critical values (abov
e
40 grams/m
3
) and if there is a source of ignition present (flame, heat, stati
c
discharge, etc.). May explode when in contact with strong acids and oxidants.
Sensitivity/mechanical impact
These products are not sensitive to mechanical impact.
Sensitivity/static discharge
These products are not sensitive to static discharge. However, fine dust clouds
may be sensitive to static discharge and lead to a dust explosive hazards.
SECTION 6. ACCIDENTAL RELEASE MEASURES
Personal Precautions
See protective measures in section 8.
Environmental Precautions None
Spill and Leak
Not likely to occur as a wood panel. Wood dust spill, sweep with wet technique or
vacuum and avoid creating airborne dust conditions. Dried wood dust can be a
source of combustible and explosion hazard. Remove ignition source and provide
good ventilation where dust conditions may occur. Place recovered wood dust in a
container for proper disposal.
SECTION 7. HANDLING AND STORAGE
Safe Handling Procedures
Avoid any source of heat or ignition and avoid creating "clouds" of dust during
mechanical processes (sawing, sanding, drilling…) on wood panel. Wood dust can
be source of fire and explosion hazards. Use in a well-ventilated area. Wash
thoroughly after handling. Wash clothing before reuse.
AVOID DUST CONTACT WITH EYES AND SKIN. AVOID BREATHING DUST.
Storage Requirement
Store away from incompatibles. Keep in a cool, dry and well-ventilated area. Keep
away from any ignition source.
Incompatibility
Avoid contact with oxidizing agents and drying oils. Avoid open flame.
