FIRST AID MEASURES FIRST AID PROCEDURES Prompt removal of the material and obtaining medical attention are essential for all contact. Remove all contaminated clothing and immediately wash the exposed areas with copious amounts of water. Continue the flushing during transportation to the emergency department. Corrosive effects may be delayed (up to 72 hours), and damage may occur without the sensation or onset of pain. Contact local poison control centre for further guidance. General Guidelines: Move victim to fresh air. Give artificial respiration ONLY if breathing has stopped. Give cardiopulmonary resuscitation (CPR) if there is no breathing AND no pulse. Oxygen administration may be beneficial in this situation but should only be administered by personnel trained in its use. Obtain medical attention IMMEDIATELY. Inhalation: Prompt removal of the material from the skin is essential. Remove all contaminated clothing and immediately wash the exposed areas with copious amounts of water for a minimum of 30 minutes or up to 60 minutes for critical body areas. Obtain medical attention IMMEDIATELY. See "Note to Physicians" below. Skin Contact: Immediately flush eyes with running water for a minimum of 30 minutes, preferably up to 60 minutes. Hold eyelids open during flushing. If irritation persists, repeat flushing. Do not transport victim until the recommended flushing period is completed unless flushing can be continued during transport. Eye Contact: Corrosive! Toxic effects are principally related to its corrosive properties. Toxic effects may be delayed. Harmful if inhaled or swallowed. Causes severe skin and eye burns. Mists or sprays are extremely irritating to eyes and respiratory tract. Causes delayed lung injury. May cause respiratory sensitization or other allergic responses. See "Other Health Effects" Section. Can decompose at high temperatures forming toxic gases. A readily obtained degradation product is sulphur dioxide. Contents may develop pressure on prolonged exposure to heat. EMERGENCY OVERVIEW: POTENTIAL HEALTH EFFECTS Corrosive! Product may cause severe irritation of the nose, throat and respiratory tract. Repeated and/or prolonged exposures may cause productive cough, running nose, bronchopneumonia, pulmonary oedema (fluid build-up in lungs), and reduction of pulmonary function. Toxic effects may be delayed. Airborne concentration of dust, mist or spray may cause damage to the lung tissue which could produce chemical pneumonia. Can cause injury to entire respiratory tract. If heated to the point where sulphur dioxide gas is driven off, then this gas is highly irritating to the respiratory tract. May cause respiratory sensitization or other allergic responses. See "Other Health Effects" Section. Inhalation: Corrosive! Burns (chemical) can occur if not promptly removed. Concentrated solutions may cause pain and deep and severe burns to the skin. Prolonged and repeated exposure to dilute solutions often causes irritation, redness, pain and drying and cracking of the skin. Prolonged and repeated contact may lead to dermatitis. Toxic effects may be delayed. Skin Contact: Corrosive! Skin absorption is a secondary concern to the continual destruction of tissue while the product is in contact with the skin. Burns (chemical) can occur if not promptly removed. Skin Absorption: Extremely corrosive! This product causes corneal scarring and clouding. Glaucoma, cataracts and permanent blindness may occur. Eye Contact: Corrosive! Ingestion is not a likely route of exposure. This product causes severe burning and pain in the mouth, throat and abdomen. Vomiting, diarrhea and perforation of the esophagus and stomach lining may occur. Ingestion: Corrosive effects on the skin and eyes may be delayed, and damage may occur without the sensation or onset of pain. Strict adherence to first aid measures following any exposure is essential. May cause violent colic, allergic reactions, bronchoconstriction, cardiovascular effects, chemical pneumonitis, pulmonary oedema and central nervous system (CNS) depression. Pulmonary oedema is the build-up of fluid in the lungs that might be fatal. Symptoms of pulmonary oedema, such as shortness of breath, may not appear until several hours after exposure and are aggravated by physical exertion. (4) CNS depression is characterized by headache, dizziness, drowsiness, nausea, vomiting and incoordination. Severe overexposures may lead to coma and possible death due to respiratory failure. May cause respiratory sensitization or other allergic responses. Sulphite-sensitive people who inhale or ingest this product may experience severe allergic reaction. Exposure to small amounts of sulfites have been reported to cause hypersensitivity reaction in certain susceptible individuals, especially asthmatics. Symptoms include hives, respiratory distress, flushing, gastro-intestinal disturbances and contact dermatitis. (3) Sulphur dioxide can be released if the product is used improperly in acidic or moist conditions. Sulphur dioxide is toxic and can cause death in extreme cases, eg: if the gas is released into a poorly ventilated area. (3) Other Health Effects: Sodium Bisulphite Solution, 15 - 40 % Brenntag Canada Inc. Date of Revision: 2009 March 06 WHMIS Number : 00061372 Page 3 of 9 Do not attempt to give anything by mouth to an unconscious person. IMMEDIATELY contact local Poison Control Centre. If victim is alert and not convulsing, rinse mouth out and give 1 to 2 glasses of milk. Water may be used if milk is not available but it is not as effective. If spontaneous vomiting occurs, have victim lean forward with head down to avoid breathing in of vomitus, rinse mouth and administer more milk or water. IMMEDIATELY transport victim to an emergency facility. DO NOT give acidic agents (e.g., citrus juices or vinegar) to "neutralize" the alkali. This action may cause an exothermic reaction and burn the esophagus. Ingestion: Immediate consultation with the local Poison Control Centre should be initiated. Severe and sometimes delayed (up to 72 hours) local and systemic reactions can occur. Treatment for corrosive chemical contact with skin after initial flushing procedures: 1. Immerse the exposed part immediately in ice water to relieve pain and to prevent swelling and blistering. Place cold packs, ice or wet cloths on the burned area if immersion is not possible. 2. Remove anything that is constrictive, such as rings, bracelets or footwear, before swelling begins. 3. Cover the exposed part with a clean, preferably sterile, lint-free dressing. 4. For severe exposure, immediately seek medical attention and monitor breathing and treat for shock. Due to the severely irritating or corrosive nature of the material, swallowing may lead to ulceration and inflammation of the upper alimentary tract with hemorrhage and fluid loss. Also, perforation of the esophagus or stomach may occur, leading to mediastinitis or peritonitis and the resultant complications. (3) Mucosal injury following ingestion of this corrosive material may contraindicate the induction of vomiting in the treatment of possible intoxication. Similarly, if gastric lavage is performed, intubation should be done with great care. If oral burns are present or a corrosive ingestion is suspected by the patient's history, perform esophagoscopy as soon as possible. Scope should not be passed beyond the first burn because of the risk of perforation. This product contains materials that may cause severe pneumonitis if aspirated. If ingestion has occurred less than 2 hours earlier, carry out careful gastric lavage; use endotracheal cuff if available, to prevent aspiration. Observe patient for respiratory difficulty from aspiration pneumonitis. Give artificial resuscitation and appropriate chemotherapy if respiration is depressed. Sulphur Dioxide: Persons subject to asthmatic attacks may experience asthmatic paroxysm. Any disorder inhibiting nasal respiration or any cardiovascular disease may preclude exposure to sulphur dioxide. Effects may be exacerbated in smokers. Significant variations in individual susceptibilities to sulphur dioxide probably exist. Medical supervision of all employees who handle or come in contact with respiratory sensitizers is recommended. This should include preemployment and periodic medical examinations with respiratory function tests (forced expiratory volume, forced vital capacity as a minimum). Persons with asthmatic- type conditions, chronic bronchitis, other chronic respiratory diseases or recurrent skin eczema or sensitization should be excluded from working with this product. Once a person is diagnosed as sensitized, no further exposure to any sensitizer should be permitted. Medical conditions that may be aggravated by exposure to this product include diseases of the skin, eyes or respiratory tract, neurological, cardiovascular and skin disorders. Note to Physicians: 5.

ACCIDENTAL RELEASE MEASURES Information in this section is for responding to spills, leaks or releases in order to prevent or minimize the adverse effects on persons, property and the environment. There may be specific reporting requirements associated with spills, leaks or releases, which change from region to region. See Section 13, "Deactivating Chemicals". In all cases of leak or spill contact vendor at Emergency Number shown on the front page of this MSDS. Wear respirator, protective clothing and gloves. Replace damaged containers immediately to avoid loss of material and contamination of surrounding atmosphere. Spilled material may cause floors and contact surfaces to become slippery. Do not use combustible materials such as sawdust as an absorbent. Recover spilled material on non-combustible absorbents, such as sand or vermiculite, and place in covered containers for disposal. Use spark- resistant tools. Eliminate all sources of ignition. Collect product for recovery or disposal. For release to land, or storm water runoff, contain discharge by constructing dykes or applying inert absorbent; for release to water, utilize damming and/or water diversion to minimize the spread of contamination. Ventilate enclosed spaces. Notify applicable government authority if release is reportable or could adversely affect the environment. Containment and Clean-Up Procedures: 7. HANDLING AND STORAGE HANDLING Use normal "good" industrial hygiene and housekeeping practices. Containers exposed to heat may be under internal pressure. These should be cooled and carefully vented before opening. A face shield and apron should be worn. Clean all containers of residues before adding the product. This will avoid potential violent reaction with unknown residues. (3) Enforce NO SMOKING rules. When diluting, add this material/product to water in small amounts to avoid spattering. Never add water to this material/product. The water should be lukewarm. Never start with hot or cold water. Add small quantities of this material slowly to large quantities of water, stirring constantly all the while. Constant stirring is necessary to avoid concentration of the product at the bottom of the mix vessel. Such concentration of the product may result in a violent exotherm with boiling of the liquid resulting in splashing, spattering or a violent eruption of a highly corrosive solution if the addition is too rapid or without sufficient stirring. Handling Practices: See Section 8, "Engineering Controls". Ventilation Requirements: Use only with adequate ventilation and avoid breathing aerosols ( vapours or mists ). Avoid contact with eyes, skin or clothing. Wash thoroughly with soap and water after handling. Wash contaminated clothing thoroughly before re-use. Do not store or transport with food or feed. Corrosive residue is most likely to be deposited at process vents or storage tanks, especially during filling operations. The use of compressed air to force corrosive materials from delivery trucks is of special concern. Scrubbing the exhaust of these vents is highly recommended. Jurisdictional regulations should be consulted to determine required practices. Sulphur Dioxide: When necessary, installation of sulphur dioxide monitors is recommended for the warning of dangerous levels of sulphur dioxide gas. (3) Other Precautions: STORAGE Ideal storage temperature is 10 to 30 °C. Do not store below 10 °C. This product will freeze at 6 °C.
