4. First Aid Measures

Ingestion: Rinse mouth thoroughly with water immediately, repeat until all traces of product have been removed. DO NOT INDUCE VOMITING. Seek medical advice if
effects persist.
Inhalation: Inhalation of any vapours from this product is not likely to present an acute hazard. If inhaled, remove from contaminated area to fresh air immediately.
Apply artificial respiration if not breathing. If breathing is difficult, give oxygen. Immediately obtain medical aid if cough or other symptoms appear
Skin Contact: Irritation unlikely. If irritation occurs wash with plenty of soap and water.
Eye Contact: Immediately irrigate with copious quantity of water for at least 15 minutes.
Eyelids to be held open. In all cases of eye contamination it is a sensible precaution to seek medical advice.
Other Information: Treat symptomatically based on judgement of doctor and individual reactions of the patient.

5. Firefighting Measures

Suitable extinguishing equipment

Fire: Use extinguishing media most appropriate for the surrounding fire. No limitations to the type of extinguishing media.
Use water, CO₂, or dry chemical depending upon other chemicals that may be present in vicinity
Only small quantities of decomposition products are expected from this product at temperatures normally achieved in a fire. This will only occur after heating to dryness.
Temperature and combustion of material in vicinity may cause formation of toxic fumes.

Special protective equipment and precautions for fire fighters

Hazardous combustion products include oxides of carbon, smoke and fumes.This material is not a flammable or combustible liquid.Use water spray to cool fire exposed containers. Containers close to fire should be removed if safe to do so.
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 approved respiratory protection, chemical resistant gloves, protective clothing and safety boots. 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. Remainder of material can be washed to drain with plenty of water.

7. Handling and Storage

Precautions for safe handling: Work in an area of good ventilation, an approved fume cupboard is preferred.
Avoid fumes.
Wear Safety glasses, gloves and protective apron.
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: Keep containers tightly closed.

Aluminium sulphate 18 hydrate	-	2	-	-

Engineering controls: The product does not contain any relevant quantities of materials with critical values that have to be monitored at the workplace. 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: When selecting gloves for use against certain chemicals, the degradation resistance, permeation rate and permeation breakthrough time should be considered.
PVC or natural rubber gloves. See Australian/New Zealand Standard AS/NZS 2161 for more information. 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: Impervious clothing. The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace.
