Description of first aid measures I SDSOI{OO . SODIUM METABISULPHITE Preparation Date 241 Augl2017 NF/FG/PHOTO GRADE Generaladvice Show this safety data sheet to the doctor in attendance. lmmediate medical attention is required. lnhalation Remove to fresh air. Get medical attention immediately if symptoms occur. Eye contact Get immediate medical advice/attention. Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes. Remove contact lenses, if present and easy to do. Continue rinsing. Keep eye wide open while rinsing. Do not rub affected area. Skin contact Wash off immediately with soap and plenty of water for at least 15 minutes. Get medical attention if irritation develops and persists. lngestion Do NOT induce vomiting. Clean mouth with water and drink afterwards plenty of water. Never give anything by mouth to an unconscious person. Call a physician. Self-protection of the first aider Avoid contact with skin, eyes or clothing. Wear personal protective clothing (see section 8). Most important symptoms and effects. both acute and delayed: Large doses may cause violent colic and diarrhea, circulatory disturbances, central nervous system depression. Possible signs and symptoms of allergic reaction include bronchoconstriction, sweating, flushing, hives, rapid heart rate, decreased blood pressure and anaphylaxis. Contact with acids liberates irritating and potentially fatal sulphur dioxide gas. May result in irritation of the mouth and gastrointestinal tract. Solutions are more irritating and may cause burns if not removed from skin promptly. May cause severe or deadly allergic reactions in some asthmatics and sulfite sensitive individuals. May cause permanent eye damage. Dust or mist may irritate or burn eyes. Sulfite sensitive individuals may experience an allergic reaction with nausea, diarrhea, itching, swelling, hives, acute asthma attack, loss of consciousness or anaphylactic shock. May cause irritation of the respiratory tract. Repeated or prolonged contact may cause irritation. Solutions can cause severe eye irritation with tearing, redness, or a stinging or burning feeling. lndication of anv immediate medical attention and special treatment needed: Note to physicians Note potential for anaphylactic shock with allergic individuals. Treatment based on sound judgment of physician and individual reactions of patient. Suitable Extinguishing Media Use extinguishing media appropriate for surrounding fire Specific hazards arising from the substance or mixture Emits toxic fumes under fire conditions.
