Keep others without proper respiratory protection away from the fumes and gases and your work zone while using this product..

Medical Conditions Generally Aggravated by Exposure

Pre-existing skin conditions may be aggravated by exposure to this product. Pre-existing respiratory conditions may be aggravated by exposure to welding fumes. Pre-existing kidney disorders.

Principle Routes of Exposure

Eyes. Skin contact. Inhalation of welding fumes. General Welding Statement Fumes and gases can be dangerous to your health. Heat rays (Infrared Radiation) from flame or hot metal can injure eyes.

Potential health effects

Eyes Eye contact may cause mechanical irritation. Risk of serious damage to eyes. Skin Prolonged skin contact may cause skin irritation and/or dermatitis. Causes burns. _______________________________________________ Page 1 / 4 Short term overexposure to welding fumes may result in dizziness, nausea, or dryness or irritation of nose, throat, or eyes. Long term exposure may lead to iron deposits in the lungs and is believed by some investigators to affect pulmonary function. Inhalation of magnesium and copper fumes can cause metal fume fever . Inhalation of copper oxide and zinc oxide fumes can cause metal fume fever. Initial symptoms of metal fume fever can include sweating, shivering, headache, fever, chills, thirstiness, muscle aches, nausea, vomiting, weakness, and tiredness . Long term exposure can lead to Manganism.The central nervous system is affected and symptoms include muscular weakness and tremor. Exposed workers should get quarterly medical examinations for manganism. Symptoms may be similar to Parkinson's Disease, including slowness, changes in handwriting, gait impairment, muscle spasms and cramps, and less commonly, tremor and behavioral changes. Long term overexposure to nickel compounds may cause lung fibrosis, edema or pneumoconiosis. Chronic exposure to inert dusts of silicon can cause increased airway resistance and contributes to chronic bronchitis . Symptoms of poisoning may not appear for several hours. Keep under medical supervision for at least 48 hours. Ingestion Ingestion may cause gastrointestinal irritation, nausea, vomiting and diarrhea. Severe ingestion over- exposure of copper can be fatal.
