Medical Conditions Generally Aggravated by Exposure

Pre-existing respiratory conditions may be aggravated by exposure to welding fumes.

Principle Routes of Exposure

Inhalation of welding fumes. General Welding Statement Arc Rays can injure eyes and burn skin. Electric shock can kill. Fumes and gases can be dangerous to your health. Heat rays (Infrared Radiation) from flame or hot metal can injure eyes. Noise can damage hearing. Some gaseous products from the welding process such as chromium and/or nickel can reach their PEL before the General Exposure Limit of 5 mg/ cu.m for welding fumes is reached. . The ACGIH and

Potential health effects

Eyes May cause the following effects:. Redness. Tearing. Irritation. Skin Skin Irritation. _______________________________________________ Page 1 / 5 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. Iron deposits in the lungs may cause siderosis. Prolonged over exposure to molybdenum may cause loss of appetite, weight loss, loss of muscle coordination, difficulty breathing and anemia. Chronic exposure to high levels of manganese dust and fumes can cause nervous system disorders, pneumonitis (inflammation of lung tissue), and may cause fibrosis (scarring of lung tissue) and reproductive disorders in males . Long term overexposure to nickel compounds may cause lung fibrosis, edema or pneumoconiosis. Exposure to the flouride ion may cause hypocalcemia-calcium deficiency in the blood that can result in muscle cramps and inflammation and necrosis of mucous membranes. Respirable Crystalline Silica, ( Quartz) can cause silicosis, a fibrous scarring of the lungs and possibly cancer . Short term (acute) overexposure to welding fumes may result in the following effects. Possible asphyxiation. Pulmonary edema. Death. Ingestion Irritation of the gastrointestinal system.
