|First Aid Measures||M|
|Inhalation||Remove victim to fresh air. Do not use mouth-to-mouth method if victim inhaled the substance; induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult|
|Ingestion||If swallowed, do NOT induce vomiting. Give a glass of water to be taken slowly. Seek urgent medical assistance.|
|Skin||If skin contact occurs, remove contaminated clothing and wash skin thoroughly. Wash clothing before re-use. Seek medical assistance.|
|Eye||If in eyes, hold eyes upen, flood with water for at least 15 minutes. Seek urgent medical assistance.|
|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.|
|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||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|
|Unsuitable Extinguishing Media||M|
|6. ACCIDENTAL RELEASE MEASURES|
|Methods and Materials for Containment and Clean Up Procedures||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||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|
|National Exposure Standards||Name||STEL (mgm3)||STEL (ppm)||TWA (mgm3)||TWA (ppm)||FootNote|
|Sodium hydroxide||2||Peak limitation|
|Biological Limit Values||M|
|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.

|11. TOXICOLOGICAL INFORMATION|
|Toxicology Information||No adverse health effects are expected, if the product is handled in accordance with this Safety Data Sheet and the product label. Symptoms and effects that may arise if the product is mishandled and overexposure occurs are:|
|Inhalation||Inhalation of dusts or concentrated mists may cause damage to the upper respiratory tract and lungs. Symptoms may range from a mild irritation of the mucous membranes, cough, a burning sensation, laboured breathing, sneezing, sore throat, a runny nose, to severe|
pneumonitis (irritation and inflammation of lung tissues). Inhalation may also cause pulmonary oedema (fluid build-up in the lungs), with the potential to become a medical emergency. Onset of symptoms may be delayed for several hours.
|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. May cause perforation of the stomach and intestines, and the sites of subsequent scarring have been associated with the later development of stomach cancer. Internal damage may not be apparent until|
days after exposure, but may still prove fatal.
|Skin||Causes severe, deep burns. Exposure to dusts or mists may cause small burns, redness and a rash.|
|Eye||Corrosive to eyes. Contact with the eyes rapidly causes severe damage to the tissues. May cause redness, pain, blurred vision. May cause severe, deep burns and permanent impairment to, or total loss of, sight.|
|Chronic Effects||Prolonged contact may cause severe eye irritation and some form of permanent eye damage may occur. Prolonged or repeated skin contact will lead to necrosis (death) of the skin.|
