4 FIRST AID MEASURESFor advice, contact a Poisons Information Centre ( phone Australia 131 126; New Zealand 0800 764 766) or :Remove victim from area of exposure - avoid becoming a casualty. Remove contaminated clothing and loosenremaining clothing. Allow patient to assume most comfortable position and keep warm. Keep at rest until fullyrecovered. For all but the most minor symptoms arrange for patient to be seen by a doctor as soon as possible, eitheron site or at the nearest Contact:If spilt on large areas of skin or hair, immediately drench with running water and remove clothing. Continue to washskin and hair with plenty of water (and soap if material is insoluble) until advised to stop by the Poisons InformationCentre or a Contact:If in eyes, hold eyelids apart and flush the eye continuously with running water.

5 Continue flushing until advised to stopby a Poisons Information Centre or a doctor, or for at least 15 Name: CAUSTIC SODA - LIQUID (46%-50%)Issued: 11/05/2015 Ingestion:Immediately rinse mouth with water. If swallowed, do NOT induce vomiting. Give a glass of water. Seek immediatemedical No: 000031006701 Indication of immediate medical attention and special treatment needed:Treat symptomatically. Can cause corneal : 65. FIRE FIGHTING MEASURESPage 2 of 7 Safety Data SheetSuitable Extinguishing Media:Not combustible, however, if material is involved in a fire use: Fine water spray, normal foam, dry agent (carbondioxide, dry chemical powder).Hazchem or Emergency Action Code: 2 RSpecific hazards arising from the chemical:Non-combustible protective equipment and precautions for fire-fighters:Not combustible, however following evaporation of aqueous component residual material can decompose if involvedin a fire, emitting toxic fumes.

6 Contact with metals may liberate hydrogen gas which is extremely flammable. Firefighters to wear self-contained breathing apparatus and suitable protective clothing if risk of exposure to products ACCIDENTAL RELEASE MEASURESE mergency procedures/Environmental precautions:Clear area of all unprotected personnel. If contamination of sewers or waterways has occurred advise localemergency precautions/Protective equipment/Methods and materials for containment and cleaning up:Slippery when spilt. Avoid accidents, clean up immediately. Wear protective equipment to prevent skin and eyecontact and breathing in vapours. Work up wind or increase ventilation.

7 Contain - prevent run off into drains andwaterways. Use absorbent (soil, sand or other inert material). Collect and seal in properly labelled containers ordrums for disposal. Caution - heat may be evolved on contact with HANDLING AND STORAGEThis material is a Scheduled Poison S6 and must be stored, maintained and used in accordance with the for safe handling:Avoid skin and eye contact and breathing in vapour, mists and Name: CAUSTIC SODA - LIQUID (46%-50%)Conditions for safe storage, including any incompatibilities:Store in cool place and out of direct sunlight. Store away from incompatible materials described in Section 10. Storeaway from foodstuffs.

8 Do not store in aluminium or galvanised containers nor use die-cast zinc or aluminium bungs;plastic bungs should be used. At temperatures greater than 40 C, tanks must be stress relieved. Keep containersclosed when not in use - check regularly for : 11/05/2015 Substance No: 0000310067018. EXPOSURE CONTROLS/PERSONAL PROTECTIONV ersion: 6 Control Parameters: No value assigned for this specific material by Safe Work Australia. However, WorkplaceExposure Standard(s) for constituent(s):Page 3 of 7 Sodium hydroxide: Peak Limitation = 2 mg/m3 Safety Data SheetAs published by Safe Work Australia Workplace Exposure Standards for Airborne Limitation - a maximum or peak airborne concentration of a particular substance determined over the shortestanalytically practicable period of time which does not exceed 15 Workplace Exposure Standards are guides to be used in the control of occupational health hazards.

9 Allatmospheric contamination should be kept to as low a level as is workable. These workplace exposure standardsshould not be used as fine dividing lines between safe and dangerous concentrations of chemicals. They are not ameasure of relative engineering controls:Ensure ventilation is adequate to maintain air concentrations below Workplace Exposure Standards. Keep containersclosed when not in in the handling and application of this material, safe exposure levels could be exceeded, the use of engineeringcontrols such as local exhaust ventilation must be considered and the results documented. If achieving safe exposurelevels does not require engineering controls, then a detailed and documented risk assessment using the relevantPersonal Protective Equipment (PPE) (refer to PPE section below) as a basis must be carried out to determine theminimum PPE protection measures, such as Personal Protective Equipment (PPE):The selection of PPE is dependent on a detailed risk assessment.

10 The risk assessment should consider the worksituation, the physical form of the chemical, the handling methods, and environmental factors. OVERALLS, CHEMICAL GOGGLES, FACE SHIELD, GLOVES (Long), APRON, RUBBER overalls, chemical goggles, face shield, elbow-length impervious gloves, splash apron or equivalent chemicalimpervious outer garment, and rubber boots. Always wash hands before smoking, eating, drinking or using the contaminated clothing and other protective equipment before storage or determined by a risk assessment an inhalation risk exists, wear a suitable mist respirator meeting the requirementsof AS/NZS 1715 and AS/NZS PHYSICAL AND CHEMICAL PROPERTIESP hysical state:LiquidColour:Colourless to Slightly ColouredSolubility:Miscible with @20 CRelative Vapour Density (air=1):Not availableVapour Pressure (20 C) mm Hg (calculated)Flash Point ( C):Not applicableFlammability Limits (%):Not applicableProduct Name: CAUSTIC SODA - LIQUID (46%-50%)Autoignition Temperature ( C):Issued.
