5. Firefighting Measures

Suitable extinguishing equipment

Fire

Use fire extinguishing methods suitable to surrounding conditions.

HAZCHEM

• Hazardous combustion products include oxides of carbon.
• Product is not flammable or combustible. Containers close to fire should be removed if safe to do so.

Special protective equipment and precautions for fire fighters

6. Accidental Release Measures

Personal precautions, protective equipment and emergency procedures

Wear appropriate respiratory protection and protective clothing. Evacuate all non-essential personnel from affected area. Do not breathe vapours. Ensure adequate ventilation.

Environmental precautions

In the event of a major spill, prevent spillage from entering drains or water courses.

Methods and materials for containment and clean up

• Stop leak if safe to do so and absorb spill with sand, earth, vermiculite or some other absorbent material.
• Collect the spilled material and place into a suitable container for disposal. Material may be slippery when
• spilt. Wash residue to drain with planty of water.

7. Handling and Storage

Precautions for safe handling

• Use of safe work practices are recommended to avoid eye or skin contact and inhalation of vapours. Use only
• outdoors or in a well-ventilated area.
• Food, beverages and tobacco products should not be stored or consumed where this material is in use.
• Always wash hands before smoking, eating, drinking or using the toilet. Wash contaminated clothing and
• other protective equipment before storage or re-use. Provide eyewash fountains and safety showers in close
• proximity to points of potential exposure.

Conditions for safe storage

• Store in a cool, dry and well ventilated area out of direct sunlight. Keep in original container tightly closed
• when not in use. Protect from heat, sparks, open flames and other sources of ignition. Keep away from strong
• alkalies, acids and oxidising agents.

8. Exposure Controls / Personal Protection

Exposure Standards

Engineering controls

Ensure adequate ventilation of the working area.

Personal protective equipment

Eye and face protection

• Eye and face protectors for protection against splashing materials or liquids. See Australian/New Zealand
• Standard AS/NZS 1337 for more information.

Skin protection

• PVC or rubber gloves. See Australian/New Zealand Standard AS/NZS 2161 for more information.
• When selecting gloves for use against certain chemicals, the degradation resistance, permeation rate andpermeation breakthrough time should be considered.
• Occupational protective clothing (depending on conditions in which it has to be used, in particular as regards
• the period for which it is worn, which shall be determined on the basis of the seriousness of the risk, the
• frequency of exposure to the risk, the characteristics of the workstation of each worker and the performance of
• the protective clothing). See Australian/New Zealand Standard AS/NZS 4501 for more information.

Body protection

Not available.

Respiratory protection

• The use of a dustmask or half-face respirator with a P1 filter is recommended.
• Filter capacity and respirator type depends on exposure levels.
• If entering spaces where the airborne concentration of a contaminant is unknown then the use of a selfcontained
• breathing apparatus (SCBA) with positive pressure air supply is recommended.
• See Australian Standards AS/NZS 1715 and 1716 for more information.
