ALL-STATE ALUMINUM AND MAGNESIUM BRAZING

SECTION 2: Hazards identification

Emergency Overview: A white, grey or blue powder with no odor. Can irritate or burn skin, especially in the presence of moisture. Toxic if swallowed. Powders can cause irritation or burns to skin, eyes, digestive tract and respiratory tract, especially in the presence of moisture. Contact with moisture may release fluorides in acidic form (HF) for which specialized first aid may be required. Toxic and may be fatal if swallowed. Gloves should be worn when handling to prevent contact with product. Persons with a pacemaker should not go near brazing and welding operations until they have consulted their doctor and obtained information from the manufacturer of the device. When these products are used in a brazing or welding process, the most important hazards are heat, radiation, electric shock and welding fumes. Heat: Spatter and melting metal can cause burn injuries and start fires. Radiation: Arc rays can severely damage eyes or skin. Electricity: Electric shock can kill. Fumes: Overexposure to brazing and welding fumes may result in symptoms like metal fume fever, dizziness, nausea, dryness or irritation of the nose, throat or eyes. Chronic overexposure to brazing and welding fumes may affect pulmonary function. Prolonged inhalation of nickel and chromium compounds above safe exposure limits can cause cancer. Overexposure to manganese and manganese compounds above safe exposure limits can cause irreversible damage to the central nervous system, including the brain, symptoms of which may include slurred speech, lethargy, tremor, muscular weakness, psychological disturbances and spastic gait. Chronic exposure to fluorides above safe exposure levels can cause changes in bone density and the teeth (fluorosis). Zinc chloride vapors produce irritation to the throat and lungs. Flame When used with combustible gas equipment (e.g., oxy-acetylene torch), read the use and safety information for that Processing: equipment.
