Unsuitable extinguishing
media
: High volume water jet
Specific hazards during fire
fighting
: Contact with incompatible materials or exposure to
temperatures exceeding SADT may result in a self-
accelerating decomposition reaction with release of flammable
vapors which may auto-ignite.
The product burns violently.
Flash back possible over considerable distance.
Vapors may form explosive mixtures with air.
The product will float on water and can be reignited on surface
water.
Cool closed containers exposed to fire with water spray.
Specific extinguishing meth-
ods
: Do not use a solid water stream as it may scatter and spread
fire.
Remove undamaged containers from fire area if it is safe to do
so.
Use water spray to cool unopened containers.
Further information : Collect contaminated fire extinguishing water separately. This
must not be discharged into drains.
Fire residues and contaminated fire extinguishing water must
be disposed of in accordance with local regulations.
Use extinguishing measures that are appropriate to local
circumstances and the surrounding environment.
Special protective equipment
for fire-fighters
: Wear self-contained breathing apparatus for firefighting if
necessary.
Use personal protective equipment.
SECTION 6. ACCIDENTAL RELEASE MEASURES
Personal precautions, protec-
tive equipment and emer-
gency procedures
: Use personal protective equipment.
Ensure adequate ventilation.
Remove all sources of ignition.
Evacuate personnel to safe areas.
Follow safe handling advice and personal protective
equipment recommendations.
Beware of vapors accumulating to form explosive
concentrations. Vapors can accumulate in low areas.
Never return spills in original containers for re-use.
Treat recovered material as described in the section "Disposal
considerations".
Environmental precautions
: Prevent product from entering drains.
Prevent further leakage or spillage if safe to do so.
If the product contaminates rivers and lakes or drains inform
respective authorities.
Methods and materials for : Contact with incompatible substances can cause
