Assessment of Selected Control Technology Techniques for Welding Fumes.

PB80176068

Publication Date	1979
Personal Author	Van Wagenen, H. D.
Page Count	34
Abstract	The report presents results of a National Institute for Occupational Safety and Health (NIOSH) welding fume study undertaken to verify findings for a Battelle Institute laboratory ventilation research study when applied under industrial welding plant conditions. The NIOSH welding fume investigation was conducted at the General Tool Company, Reading, Ohio (a large modern job-shop operation). It verified Battelle's results on effect of air flow direction (in relation to the welder) on fume concentrations in the welder's breathing zone that (1) cross draft air flow (100 cfm at 90 to the welder) significantly lowers breathing zone fume concentration from that prevailing when no directional air flow is employed and (2) with directional air flow from directly behind the welder (100 fpm), breathing zone fume concentration levels are approximately equal to that prevailing when no directional air flow is employed.
