Minimizing Worker Exposure during Solid Sampling: A Strategy for Effective Control Technology.
NIOSH 1983 Dec:28 pages
A strategy for controlling worker exposures to hazardous materials during solid sampling was described. This involved a systematic approach to selecting sampling devices and peripheral control technology which would minimize hazards to workers during sample collection and still meet requirements for the sample to be usable. Primary types of sample extraction designs included cross cutting, gravity flow, auger, and retractable tube. Data from many industrial locations indicated that proper use of automatic samplers augmented with peripheral engineering control technology could keep levels of some very hazardous solids below OSHA permissible exposure levels. Effectiveness of various solid sampling techniques and peripheral control technologies have been evaluated by NIOSH in walk through and indepth studies of a number of different industrial facilities. Indepth studies included taking industrial hygiene samples for airborne solids and engineering measurements such as air velocity, pressure drops, and equipment dimensions. An example of a study involving a facility handling solid beryllium-oxide (1304569) was presented.
