A hazard evaluation was performed at Dalb, Inc. (SIC-2751, SIC- 3499), located near Ranson, West Virginia, in response to a request from management to explore possible exposures related to butyl- cellosolve (111762) solvent (ethylene-glycol-monobutyl-ether, EGBE). About 26 workers were involved in silkscreening signs for use on vending machines. None of the 14 personal exposure measurements taken for EGBE exceeded the OSHA limit of 50 parts per million (ppm), although six exceeded the American Conference of Governmental Industrial Hygienists threshold limit. On some occasions workers using EGBE to clean signs and silkscreens wore no protective masks, gloves, or goggles. A major exposure hazard existed during these operations for the absorption of EGBE through the skin. Pure EGBE was used in the spray trough and wash table areas, with large amounts of vapor release and employee exposure occurring. Exposures were high around the silkscreen printer, the open ink containers, and the conveyor area between the oven and dryer. The author concludes that some workers received excessive exposures to EGBE; skin exposure increased total exposures for some workers. The author recommends that all employees wear personal protective gloves, eye goggles and aprons when working with EGBE. Recommendations for a ventilation system are included. All open ink and solvent containers should be covered.
