Environmental surveys were conducted on June 20 and 21, 1978, to evaluate the presence of soluble barium (7440393) in the work atmosphere of welders at the Mark Steel Corporation (SIC-3325) in Salt Lake City, Utah. The evaluation was requested by a company representative on behalf of the approximately 100 affected employees. The time weighted average (TWA) exposures for soluble barium ranged from 2.20 to 6.13 milligrams per cubic meter (mg/m3), exceeding the 0.5mg/m3 OSHA standard. Exposed workers reported no adverse health problems at the time of the survey. The author concludes that welders are exposed to excessive soluble barium concentrations, however no adverse health effects can be related to the exposures. Recommendations are given for improved exhaust ventilation systems for welders and for medical monitoring of exposed workers.
