|First Aid Facilities||Eye wash. Hand wash basin. Emergency shower.|
|Advice to Doctor||Sodium hydroxide is highly corrosive. Vomiting has not been induced because of risk of aspiration into the lungs. If swallowed, may cause holes in stomach and intestines. Evacuation of stomach should not be attempted. Contact Poisons Information Centre.|
|5. Fire-fighting measures|
|Suitable extinguishing media||Water fog or fine water spray.|
|Unsuitable Extinguishing Media||M|
|Hazards from Combustion Products||M|
|Specific Methods||In case of small fire/explosion use water. In case of major emergency use PPE: breathing apparatus and protective gloves.|
|Specific hazards arising from the chemical||Not flammable. Contact with aluminium, tin, zinc or galvanised iron may generate hydrogen, a flammable gas. Will react vigorously or violently with acids, generating much heat, and giving off carbon dioxide, a simple asphyxiant. Contact with ammonium compounds will generate ammonia, a poisonous gas.|
|Precautions in connection with Fire||M|
|6. Accidental release measures|
|Methods and materials for containment and cleaning up||Remove all non-ferrous metals from area (aluminium, zinc and magnesium), if product has spilt on these metals immediately, flush them with plenty of water and shut off ignition sources, no smoking or flames in hazard area. Stop leak if you can do it without risk. Water spray may reduce vapour; but it may not prevent ignition in closed spaces.|
|Spills & Disposal||SMALL SPILLS: |
Take up with sand, dirt or vermiculite. Do NOT use sawdust. Use non-sparking tools. Place into labeled plastic drum(s) for later disposal.
Notify Emergency Services (Police or Fire Brigade). Tell them exact location, nature, hazards, quantities, type of vehicle and any other information that would be helpful. Contain spill. Remove all ignition sources and safely stop flow of spill. Bund area. Trained personnel should wear Personal Protective equipment as highlighted in this MSDS. Blanket the spill with foam or use water fog to disperse vapour clouds. Consult an expert regarding disposal of this product.
|Personal Protection||Wear protective clothing to prevent eye and skin contamination. Ensure an|
eye bath and safety shower is available. Operators are recommended to wear
full protective clothing, glasses, gloves, apron etc. including footwear.
|Environmental Precautions||Prevent spills from entering drains and waterways. Contact local emergency|
services if contamination of sewers or waterways occurs.
|Other Information||Products that contain alkali hydroxides must be kept away from non-ferrous metals, as extremely flammable hydrogen gas will be generated and if the appropriate flammability limits are reached and a source of ignition is present, a violent explosion will occur.|
|7. Handling and storage|
|Precautions for Safe Handling||Handle according to good manufacturing and industrial hygiene practices. Do|
not drink, eat or smoke while handling. Respect good personal hygiene.
|Conditions for safe storage, including any incompatibilities||Store in a cool place and out of direct sunlight. Store away from sources of heat or ignition, strong acids, aluminium, zinc and magnesium or their alloys. All equipment must be earthed. Store in original packages as approved by manufacturer. Check all fittings, valves, reticulation (piping) and any ancillary equipment for leaks. A supplied air respirator or a self-contained breathing apparatus (SCBA) for emergencies should be available and checked regularly. For further information please refer to the Engineering Controls of this MSDS.|
|Unsuitable Materials||Store away from acids. Hydrogen gas is generated when undiluted material contacts aluminium, zinc or tin.|
|Additional information on precautions for use||Mixing this product with strong mineral acids such as sulfuric, nitric and/or hydrochloric acid will result in a highly exothermic (releasing heat) reaction, which may lead to a fire and potential explosion.|
|8. Exposure controls/personal protection|
|Occupational exposure limit values||Name||STEL (mgm3)||STEL (ppm)||TWA (mgm3)||TWA (ppm)||FootNote|
|Sodium hydroxide||2||Peak limitation|
|Biological Limit Values||M|
|Appropriate engineering controls||Do not use aluminium, tin, zinc or galvanised iron as materials of construction. Use in a well ventilated area. If ventilation is insufficient use a corrosive - resistant ventilation system separate from other exhaust systems. Engineering control methods to reduce hazards are preferred.|
|Personal Protective Equipment||Avoid contact with skin and eyes. Avoid breathing dusts or aerosols. Personal protection to be selected from those recommended below, as appropriate to mode of use, quantity handled and degree of hazard:-|
Face shield or safety glasses
Gloves, rubber or plastic
Plastic apron, sleeves and boots
Select and use respirators in accordance with AS/NZS 1715/1716. When the concentration of airborne contaminants reach the exposure standards then the use of a half-face respirator with P1 filter is recommended. For high concentration use an atmosphere-supplied, positive pressure demand self-contained or airline breathing apparatus supplied air respirator complying with the requirements of AS/NZS 1715 is recommended. Filter capacity and respirator type depends on exposure levels and type of contaminant.
Always maintain a high level of personal hygiene when using cleaning chemicals. That is wash hands before eating, drinking, smoking or using the toilet.

|Acute Toxicity - Oral||LD50 Oral Mouse: 40 mg/kg|
Oral Rat: 140-340 mg/kg
|Ingestion||May be fatal. Causes very serious damage to the mucous membranes and any other tissues it comes into contact with. May cause swelling of the larynx and subsequent suffocation. May cause burns in the mouth and throat, nausea, vomiting, abdominal pains and diarrhoea (occasionally bloody), fall in blood pressure, heart failure, coma and death.
