Abstract
A walk through survey was conducted at the Sacramento Air Logistics Center (SIC-3721), McClellan Air Force Base, California on June 13, 1983 to evaluate the use of High Velocity Low Volume (HVLV) technology in the aircraft maintenance industry. The HVLV system consisted of 65 ceiling drops in the bonded honeycomb shop where grinding and sanding operations created glass fiber and resin dusts. The system was operated from three 60 horsepower, 3500 revolutions per minute vacuum pumps rated at 925 cubic feet per minute at 11 inches of mercury. Preemployment and periodic physical examinations were required. Workers were required to wear disposable coveralls, and disposable dust masks were available. Workers walked through decontamination air jet showers before leaving the area to change clothes. Environmental monitoring revealed no significant dust exposures when the HVLV system was in use. Performance of the exhaust system on the 8 inch diameter nose cone sanding operation was good, but the 3 inch diameter tools were too large and the shrouds too cumbersome for use on many hand finishing tasks. The author concludes that the HVLV system is partially successful but requires additional shroud design. Further development of small tool shrouds is recommended.
