Description:

"The recommended standard compiled by NIOSH requires that occupational exposure to insoluble tungsten (7440337) and to soluble tungsten shall be controlled so than employees are not exposed at concentrations greater than 5 milligrams and 1 milligram, respectively, of tungsten per cubic meter of air, determined as a time weighted average (TWA) concentration for up to a 10 hour shift in a 40 hour week. Recommended levels for occupational exposure to dust of cemented tungsten carbide containing more than 2 percent cobalt (7440484) or more than 0.3 percent nickel (7440020) are established at 0.1 milligram of cobalt and 15 micrograms of nickel per cubic meter of air, determined as a TWA concentration for up to a 10 hour shift in a 40 hour week. Recommendations are also made for sampling and analysis, medical surveillance and counseling, engineering controls, work practices, and personal protective clothing and equipment.
