Industrial Hygiene Survey Land and Marine Enterprises Abrasive Blasting Division, Harvey, Louisiana

摘要

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. 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.
