Continue flushing with water until advised to stop by the Poisons Information Centre. • Transport to hospital, or doctor. INHALED • If fumes or combustion products are inhaled remove from contaminated area. • Lay patient down. Keep warm and rested. • Prostheses such as false teeth, which may block airway, should be removed, where possible, prior to initiating first aid procedures. • Apply artificial respiration if not breathing, preferably with a demand valve resuscitator, bag-valve mask device, or pocket mask as trained. Perform CPR if necessary. • Inhalation of vapours or aerosols (mists, fumes) may cause lung oedema. continued... sodium hypochlorite Hazard Alert Code: EXTREME Chemwatch Material Safety Data Sheet Issue Date: 14-May-2010 XC9317SC CHEMWATCH 35008 Version No:8 CD 2011/1 Page 3 of 9 Section 4 - FIRST AID MEASURES • Corrosive substances may cause lung damage (e.g. lung oedema, fluid in the lungs). • As this reaction may be delayed up to 24 hours after exposure, affected individuals need complete rest (preferably in semirecumbent posture) and must be kept under medical observation even if no symptoms are (yet) manifested. • Before any such manifestation, the administration of a spray containing a dexamethasone derivative or beclomethasone derivative may be considered. NOTES TO PHYSICIAN ■ Excellent warning properties force rapid escape of personnel from chlorine vapour thus most inhalations are mild to moderate. If escape is not possible, exposure to high concentrations for a very short time can result in dyspnea, haemophysis and cyanosis with later complications being tracheobroncho-pneumonitis and pulmonary oedema. for corrosives: -------------------------------------------------------------BASIC TREATMENT -------------------------------------------------------------• Establish a patent airway with suction where necessary. • Watch for signs of respiratory insufficiency and assist ventilation as necessary. • Administer oxygen by non-rebreather mask at 10 to 15 l/min. • Monitor and treat, where necessary, for pulmonary oedema . For acute or repeated exposures to hypochlorite solutions: • Release of small amounts of hypochlorous acid and acid gases from the stomach following ingestion, is usually too low to cause damage but may be irritating to mucous membranes. Buffering with antacid may be helpful if discomfort is evident. • Evaluate as potential caustic exposure. • Decontaminate skin and eyes with copious saline irrigation. Check exposed eyes for corneal abrasions with fluorescein staining. • Emesis or lavage and catharsis may be indicated for mild caustic exposure. Depending on the degree of exposure, periodic medical examination is indicated. The symptoms of lung oedema often do not manifest until a few hours have passed and they are aggravated by physical effort. Section 5 - FIRE FIGHTING MEASURES EXTINGUISHING MEDIA • Water spray or fog. • Foam. • Dry chemical powder. • BCF (where regulations permit). FIRE FIGHTING • Alert Fire Brigade and tell them location and nature of hazard. • Wear full body protective clothing with breathing apparatus. • Prevent, by any means available, spillage from entering drains or water course. • Use fire fighting procedures suitable for surrounding area. FIRE/EXPLOSION HAZARD • Non combustible. • Not considered a significant fire risk, however containers may burn. Decomposition may produce toxic fumes of: hydrogen chloride, metal oxides. May emit corrosive fumes. FIRE INCOMPATIBILITY ■ None known. HAZCHEM 2X Personal Protective Equipment Breathing apparatus. Gas tight chemical resistant suit.

Neutralise with sodium metabisulfite or sodium thiosulfate. MAJOR SPILLS • Clear area of personnel and move upwind. • Alert Fire Brigade and tell them location and nature of hazard. • Wear full body protective clothing with breathing apparatus. • Prevent, by any means available, spillage from entering drains or water course. Neutralise with sodium metabisulfite or sodium thiosulfate. Personal Protective Equipment advice is contained in Section 8 of the MSDS. Section 7 - HANDLING AND STORAGE PROCEDURE FOR HANDLING • Avoid all personal contact, including inhalation. • Wear protective clothing when risk of exposure occurs. • Use in a well-ventilated area. • WARNING: To avoid violent reaction, ALWAYS add material to water and NEVER water to material. SUITABLE CONTAINER ■ Liquid inorganic hypochlorites shall not to be transported in unlined metal drums. Inner packagings shall be fitted with vented closures and plastics drums and carboys shall have vented closures or be performance tested to a minimum of 250 kPa. • Glass container is suitable for laboratory quantities. • Lined metal can, lined metal pail/ can. • Plastic pail. • Polyliner drum. • Packing as recommended by manufacturer. For low viscosity materials • Drums and jerricans must be of the non-removable head type. • Where a can is to be used as an inner package, the can must have a screwed enclosure. <</>. STORAGE INCOMPATIBILITY • Contact with acids produces toxic fumes. • Metals and their oxides or salts may react violently with chlorine trifluoride and bromine trifluoride. • These trifluorides are hypergolic oxidisers. They ignites on contact (without external source of heat or ignition) with recognised fuels - contact with these materials, following an ambient or slightly elevated temperature, is often violent and may produce ignition. • The state of subdivision may affect the results. • Presence of rust (iron oxide) or other metal oxides catalyses decomposition of inorganic hypochlorites. • Contact with water can cause heating and decomposition giving off chlorine and oxygen gases. Solid hypochlorites in contact with water or moisture may generate sufficient heat to ignite combustible materials. Thermal decomposition can be sustained in the absence of oxygen. • Contact with acids produces toxic fumes of chlorine. • Bottles of strong sodium hypochlorite solution (10-14% available chlorine) burst in storage due to failure of the cap designed to vent oxygen slowly during storage. A hot summer may have exacerbated the situation. Vent caps should be checked regularly (using full personal protection) and hypochlorites should not be stored in direct sunlight or at temperatures exceeding 18 deg. C. Contact with acids produces toxic fumes of chlorine. • Avoid any contamination of this material as it is very reactive and any contamination is potentially hazardous.

Section 11 - TOXICOLOGICAL INFORMATION POTENTIAL HEALTH EFFECTS ACUTE HEALTH EFFECTS ■ Causes burns. ■ Risk of serious damage to eyes. ■ Ingestion may produce health damage*. ■ * (limited evidence). CHRONIC HEALTH EFFECTS ■ Possible skin sensitiser*. ■ Limited evidence of a carcinogenic effect*. ■ Cumulative effects may result following exposure*. ■ * (limited evidence). TOXICITY AND IRRITATION ■ Asthma-like symptoms may continue for months or even years after exposure to the material ceases. This may be due to a nonallergenic condition known as reactive airways dysfunction syndrome (RADS) which can occur following exposure to high levels of highly irritating compound. Hypochlorite salts are classified by IARC as Group 3: NOT classifiable as to its carcinogenicity to humans. Evidence of carcinogenicity may be inadequate or limited in animal testing. The material may produce moderate eye irritation leading to inflammation. Repeated or prolonged exposure to irritants may produce conjunctivitis. Hypochlorite salts are extremely corrosive and can cause severe damage to the eyes and skin. A number of fibrosarcomas and squamous cell carcinomas were observed in mice treated dermally with repeated subcarcinogenic doses of 4-nitroquinoline-1-oxide, followed by dermal treatment with sodium hypochlorite. continued... sodium hypochlorite Hazard Alert Code: EXTREME Chemwatch Material Safety Data Sheet Issue Date: 14-May-2010 XC9317SC CHEMWATCH 35008 Version No:8 CD 2011/1 Page 7 of 9 Section 12 - ECOLOGICAL INFORMATION Very toxic to aquatic organisms.
