Storage and Transport:
Store away from oxidising materials and foodstuffs. Keep containers closed at all times – check regularly for spills. Container Type: Plastic film bags inside plastic fabric bags.
Spills & Disposal

Spills: Wear self contained breathing apparatus, rubber boots and heavy rubber gloves. Avoid raising dust. Ventilate area and wash spill site after material pickup is complete. Sweep up, place in bag and hold for waste disposal.
Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber.
Fire/Explosion Hazard
Will not burn or explode. Reacts with various sulph-hydryl oxidising agents and forms complexes and adducts with metallic salts and many organic compounds including proteins and certain hydrocarbons. Incompatible with acrylaldehyde, hydrogen peroxide and nitric acid. May react violently with acrolein. Decomposition products: TOXIC fumes of carbon monoxide, carbon dioxide, nitrogen oxides and sulphur oxides.
Extinguishing Media: Evacuate area – move upwind of fire. Summon fire brigade immediately, DIAL 000, water spray, carbon dioxide, dry chemical powder, alcohol or polymer foam.

Product Name: Sodium Hydroxide U.N. Number: 1823

Other Names: Caustic Soda; Anhydrous Sodium Hydroxide, Sodium Hydrate; White
Caustic; Soda Lye
Hazchem Code: 2R
Manufacturer’s Product Code: CASODA25 Dangerous Goods Class: 8
Poisons Schedule: S6
Use: NAOH solutions are used to nuetralise acids and make sodium salts, e.g. in petrolium to remove sulphuric and organic acids; to treat cellulose in making viscose rayon and cellophane; in reclaiming rubber to dissolve out the fabric; in making plastics to dissolve casein. NaOH solutions hydrolyse fats and form soaps; they precipitate alkaloids and most metals from water solutions.

Health Effects:
Acute:
Swallowed: Ingestion of the substance causes severe burns of the mouth and the oesophagous, nausea, vomiting and edema of the pharynx. In the worst cases perforation of the gastrointestinal tract and heart failure may occur.
Eye: Contact of this substance with the eyes may cause severe lesions and possible loss of sight.
Skin: Skin contact with this substance causes severe burns and necrosis
Inhaled: Inhalation of dusts may cause pulmonary congestion with subsequent compromission of respiratory functionality followed by loss of consciousness.
Extremely irritive to respiratory tract (including mucous membranes, throat and lungs). Slightly toxic.

Chronic: prolonged and reiterated inhalations of the dusts may cause chronic disturbance of the respiratory routes. May cause dermatitis.
First Aid
If swallowed: Contact a doctor or the Poisons Information Centre immediately Give patient 1-3 cups of water DO NOT induce vomiting. Immediately transport to a hospital or doctor.
Eye: Flood eye with clean water for 15 minutes - retract eyelids often Immediately transport to hospital or doctor.
Skin: Remove all contaminated clothing including footwear. Wash affected areas thoroughly with mild soap and water. Seek medical advice.
Inhalation: R4move from contaminated area immediately; avoid becoming a casualty.
If not breathing apply artificial resuscitation. Experienced person may administer oxygen if breathing is difficult. Immediately transport to hospital or doctor. ADVICE
TO DOCTOR: Wash skin until soapiness feeling disappears.

Storage: Tightly closed. Dry. Away from acids. At room temperature
(recommendation: +15to+25 deg C). Requirements for storage rooms and containers:
No aluminium, tin or zinc containers.
Spills & Disposal
Wear appropriate protective clothing. If local regulations permit, mop up with plenty of water and run to waste, diluting greatly with running water. Otherwise transfer to container and arrange removal by disposal company. Wash site of spillage thoroughly with detergent and water. For large spillages liquids should be contained with sand or earth and both liquids and solids transferred to salvage containers. Any residues should be treated as for small spillages. No environmental hazard is anticipated provided that the material is handled and disposed of with due care and attention.
Harmful effect due to pH shift. Chemical residues are generally classified as special waste, and as such are covered by regulations, which vary according to location.
Contact your local waste disposal authority for advice, or pass to a chemical disposal company. Rinse out empty containers thoroughly before returning for recycling.
Product: There are no uniform Australian Regulations for the disposal of chemicals or residues. Chemical residues generally count as special waste. The disposal of the latter is regulated in Australia through Commonwealth, State, Territory or Local government laws and regulations. We recommend that you contact either the authorities in charge or licensed waste disposal companies, which will advise you on how to dispose of special waste.
Packaging: Disposal in compliance with official regulations. Handle contaminated packaging in the same way as the substance itself. If not officially specified differently, non-contaminated packaging may be treated like household waste or recycled.
