High volume water jet

Special hazards arising from the substance or mixture

Specific hazards during firefighting / Specific hazards arising from the chemical:

CAUTION: reignition may occur.

Supports combustion.

Do not use a solid water stream as it may scatter and spread fire.

Water spray may be ineffective unless used by experienced firefighters.

Do not allow run-off from fire fighting to enter drains or water courses.

Heating may cause decomposition with release of toxic fumes.

Combustion products:

Fire will produce smoke containing hazardous combustion products (see section 10).

Advice for firefighters

Special protective equipment for firefighters:

In the event of fire, wear self-contained breathing apparatus.

Further information:

Use water spray to cool unopened containers.

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.

Accidental release measures

Methods and materials for containment and cleaning up

Methods for cleaning up / Methods for containment:

Keep wetted with water.

Soak up with inert absorbent material and dispose of as hazardous waste.

Confinement must be avoided.

Never return spills in original containers for re-use.

Reference to other sections

Additional advice:

For personal protection see Exposure Controls/Personal Protection.

Handling and storage

Precautions for safe handling

Advice on safe handling:

For personal protection see Exposure Controls/Personal Protection.

Stable under recommended storage conditions.

Possibility of hazardous reactions

No dangerous reaction known under conditions of normal use.

Conditions to avoid

Conditions to avoid:

Confinement must be avoided.

Heat, flames and sparks.

Incompatible materials

Materials to avoid:

Contact with incompatible materials will result in hazardous decomposition.

For queries regarding the suitability of other materials please contact the supplier.

Do not mix with peroxide accelerators, unless under controlled processing.

Use only stainless steel 316, PP, polyethylene or glass-lined equipment.

Heavy metals


Hazardous decomposition products

Hazardous decomposition products:




tert-Amyl alcohol

Methyl ethyl ketone




Carbon oxides


Pivalic acid


Thermal decomposition:

SADT - (Self accelerating decomposition temperature) is the lowest temperature at which self accelerating decomposition may occur with a substance in the packaging as used in transport. A dangerous self-accelerating decomposition reaction and, under certain circumstances, explosion or fire can be caused by thermal decomposition at and above the SADT. Contact with incompatible substances can cause decomposition below the SADT.

Self-Accelerating decomposition temperature (SADT):

25 °C

Disposal considerations

Waste treatment methods


The product should not be allowed to enter drains, water courses or the soil.

Do not contaminate ponds, waterways or ditches with chemical or used container.

Hazardous waste

Dispose of contents/container in accordance with local regulation.

Contaminated packaging:

Empty remaining contents.

Dispose of as unused product.

Do not burn, or use a cutting torch on, the empty drum.

Due to the high risk of contamination recycling/recovery is not recommended.

Follow all warnings even after the container is emptied.
