Health Hazards associated with foundry operations were assessed at Pippy Foundry in Salt Lake City, Utah, on November 6 and December 16, 1968. Personal, respirable mass samples were obtained from each of the three workers. Metal shot was used for sandblasting in a Pangborn rotoblast machine in a cinderblock building ventilated by two wall exhaust fans. In the three samples, dust measurements varied from 1.83 to 3.98 milligrams per cubic meter (mg/cu m) as compared with the threshold limit value of 0.5mg/cu m for a 40 hour per week exposure. The author concludes that even though foundry operations do not produce constant dust concentrations in excess of the threshold limit value, additional exhaust ventilation should be provided. They also suggest that approved dust respirators be used during dusty operations.
