Lead Coated Copper Flashing

SECTION 2: Hazards identification

OSHA HAZARDS OVERVIEW: There are no chemical hazards from these sheets in solid form. Machining, grinding, flame cutting, or welding of the flashing will put contaminants, primarily copper and lead, in the air. Fumes and dusts from the flashing irritate the nose and throat. If too much fume is inhaled, it will cause a sweet or metallic taste in the mouth. High Concentrations of the fumes can also cause metal fume fever, which resembles the flu. Breathing or swallowing lead dust or fume from the casting can result in lead poisoning. The effects are fatigue, headache, loss of appetite, aching bones and muscular weakness. Overexposure for a long time can cause kidney damage, nervous system damage, reproductive effects, and anemia. Because of this potential hazard from metal dust and fumes, grinding, welding operations, etc., should be done under local exhaust ventilation. If ventilation is not adequate, wear a NIOSH approved dust and fume respirator. In addition, good hygiene practices should be followed. Smoking should not be allowed in lead handling areas. Wash hands thoroughly before eating. Keep work area clean.
