CORESHIELD FLUX CORED WELDING ELECTRODES

SECTION 2: Hazards identification

Emergency Overview: Metal wires in varying colors. These products are normally not considered hazardous as shipped. Gloves should be worn when handling to prevent cuts and abrasions. Some of these products contain nickel, which is classified as a skin sensitizer and a suspect carcinogen. Some of these products contain barium fluoride, which is classified as harmful by inhalation and ingestion. Some of these products contain potassium fluorosilicate which is classified as toxic by inhalation, skin contact and ingestion. In the form that these substances are present in these products, they do not contribute to a hazard classification of the product. These products contain quartz, but normally not in an inhalable fraction. Quartz can cause silicosis and may cause cancer. Skin contact is normally no hazard but should be avoided to prevent possible allergic reactions. Persons with a pacemaker should not go near welding or cutting operations until they have consulted their doctor and obtained information from the manufacturer of the device. When these products are used in a 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 welding fumes may result in symptoms like metal fume fever, dizziness, nausea, dryness or irritation of the nose, throat or eyes. Chronic overexposure to welding fumes may affect pulmonary function. Prolonged inhalation of nickel 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.
