Abstract
Real time techniques were used to identify and quantify dust exposures at repetitive tasks. The task studied was a bag emptying operation. The bags weighed 50 pounds and were loaded with lead- chromate (7758976). Videotapes were made of workers emptying 65 bags in a 24 minute period. Seven specific tasks were identified along with the relative contribution of each to the worker's overall dust exposure. Pushing empty bags into barrels for subsequent disposal was the major source of airborne dust. Lesser but significant amounts of dust became airborne when the bags were cut open and lifted to the emptying shelf of the dump station. The bag disposal unit within the dump station control system was awkward for the workers to use and necessitated disposal outside the control area. Redesign of the disposal system was associated with a 33% reduction in atmospheric dust. The authors encourage the use of video recording and dust monitoring overlay to improve work practices.
