5. Firefighting Measures

Suitable extinguishing equipment

Fire: Use extinguishing media suitable for surrounding fire situation. This material is not a flammable or combustible liquid.
Large Fire: Use extinguishing media suitable for surrounding fire situation. This material is not a flammable or combustible liquid.
HAZCHEM: Not available.

Special protective equipment and precautions for fire fighters

Fire fighters to wear Self-contained breathing apparatus (SCBA) in confined spaces, in oxygen deficient atmospheres or if exposed to products of decomposition. Full protective clothing is also recommended. If safe to do so, move undamaged containers from fire area.

6. Accidental Release Measures

Personal precautions, protective equipment and emergency procedures: No further relevant information available.
Environmental precautions: Not available.
Methods and materials for containment and clean up: Bund area using sand or soil ? to prevent run off into drains and waterways. Use absorbent (soil, sand, vermiculite or other inert material). Collect and seal in properly labelled containers for disposal. Remainder of material can be washed to drain with plenty of water.

7. Handling and Storage

Precautions for safe handling: Wear appropriate protective equipment while handling. Refer to Section 8.
Conditions for safe storage: Store in a cool place and out of direct sunlight. Store away from sources of heat or ignition. Store away from oxidising agents. Keep containers closed, when not using the product. Store in original packages as approved by manufacturer.

8. Exposure Controls / Personal Protection

Exposure Standards

Engineering controls: Maintain adequate ventilation at all times. In most circumstances natural ventilation systems are adequate unless the material is heated, reacted or otherwise changed in some type of chemical reaction, then the use of a local exhaust ventilation system is recommended.

Personal protective equipment

Eye and face protection: Chemical goggles or face shield to protect eyes.
Skin protection: PVC or natural rubber.
Body protection: PVC or natural rubber apron or splash suit.
Respiratory protection: Avoid breathing of vapours/gases. Select and use respirators in accordance with AS/NZS 1715/1716. The use of a P1 dust mask (disposable) or with replaceable filters is recommended. Filter capacity and respirator type depends on exposure levels and type of contaminant. If entering spaces where the airborne concentration of a contaminant is unknown then the use of a Self-contained breathing apparatus (SCBA) with positive pressure air supply complying with AS/NZS 1715 / 1716, or any other acceptable International Standard is recommended.
