Abstract
An industrial survey was conducted at the Abrasive Blasting Division of Land and Marine Enterprises (SIC-1629) in Harvey, Louisiana to monitor the use of a coal slag abrasive blasting agent for blasting new steel. Blasters at the site were equipped with protective clothing and a double protective respiratory system consisting of a disposable respirator worn over the nose and mouth and a carbon filtered air supplied helmet fastened to the protective garment. Environmental concentrations of respirable dust ranged from 1.08 to 72.7 micrograms per cubic meter of air. The particle diameters ranged from 0.21 to 1.80 microns. The authors conclude that although atmospheric dust concentrations are high, the workers are adequately protected by the double respiratory protective system. They recommend using an expert abrasive blaster to train blasters in proper blasting techniques to reduce the quantities of dust produced.
