This historical photograph was provided by the Center for Disease Control's (CDC), National Institute for Occupational Safety and Health (NIOSH). It depicted two factory workers at a Carboloy� plant, who were working with heated metals at their workstation. The immediate area was being ventilated in order to extract noxious fumes that were the biproducts of the metallurgic process. Though the air was being cleansed, the workers were not wearing filtered breathing masks, nor were they wearing gloves, or 'protective' goggles, though one man was wearing eyeglasses. Carboloy� is an alloy created by combining tungsten with cobalt or nickel and carbon. The alloy is extremely hard, harder than steel, and is used to cut steel, porcelain, quartz and other brittle materials. Water is often used to extract airborne particulates from workplace environments that are subsequently filtered from the water, which is then recirculated.
