4. First Aid Measures

Ingestion

If swallowed, do not induce vomiting. Never give anything by mouth to an unconscious person. Seek immediate medical attention.

Inhalation

If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Seek medical attention if breathing problems develop. Do not use mouth-to-mouth method, use an alternative method or a proper respiratory device.

Skin Contact

In case of skin contact, immediately remove contaminated clothing and wash affected areas with water and soap. Seek medical attention if symptoms persist.

Eye Contact

In case of eye contact, hold eyelids open and rinse with water for at least 15 minutes. Seek immediate medical attention.

Other Information

No further relevant information available.

5. Firefighting Measures

Suitable extinguishing equipment

Fire

Water fog, foam, dry chemical or carbon dioxide.

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. Extinguish all sources of ignition. Avoid sparks and open flames. No smoking.

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. Do not use sawdust. Collect the spilled material and place into a suitable container for disposal. Blanket the spill with foam or use water spray to disperse vapours. Use only non-sparking tools.

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. Take precautionary measures against static discharge. 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, oxidising agents and nitrates.

8. Exposure Controls / Personal Protection

Exposure Standards

Engineering controls

Maintain air concentration below occupational exposure standards, providing adequate ventilation. Use explosion-proof ventilating equipment.

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 and permeation 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

No information available.

Respiratory protection

• When vapours approach the exposure standards then the use of a half-face organic vapour respirator with dust/mist filter is recommended.
• When vapours exceed the exposure standards, the use of an positive pressure demand self-contained or airline breathing apparatus 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.
