Environmental surveys to evaluate potential health hazards associated with the grinding, drilling, milling-slotting, and grooving operations at an iron (7439896) and copper (7440508) sintered metal parts manufacturing facility reveals that the levels of iron, copper, lead (7439921), magnesium (7439954), zinc (7440666), tin (7440315), antimony (7440360), molybdenum (7439987), graphite (7782425) and silica (7631869) dust in the air do not exceed the levels recommended by the prevailing health standards. Sound levels measured in a number of operations exceed the standard for noise exposure. Previously reported respiratory disorders disappear subsequent to ventilation improvements.
