4. First Aid Measures

Ingestion: If swallowed, do not induce vomiting. Immediately rinse mouth with water. Give a glass of water. Never give anything by mouth to an unconscious person. Seek medical attention if symptoms persist.
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.
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 medical attention
if symptoms persist.
Other Information: No further relevant information available.

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.
Smoke and oxides of carbon.

Special protective equipment and precautions for fire fighters

When fighting a major fire wear self-contained breathing apparatus and protective equipment.

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 plenty 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

Material	TWA ppm	TWA mg/m³	STEL ppm	STEL mg/m³
Sodium metabisulphite	-	5 mg/m³	-	-
Hydrochloric acid	-	-	5 ppm	7.5 mg/m³

Engineering controls: Maintain air concentration below occupational exposure standards, providing adequate ventilation.

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: Not available.
Respiratory protection: When vapours approach the exposure standards then the use of a dustmask or half-face respirator with a P1filter 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.
