Walk-Through Survey Report: Control Technology for Airline Maintenance Facility at: United Airlines Maintenance Facility, San Francisco, California, Report No. CT-145-21a.
NIOSH 1983 Nov; :1-7
A control technology survey was conducted at the United Airlines maintenance facility (SIC-4582), San Francisco, California, in November 1983. The purpose of the visit was to explore the facility's use of high velocity low volume (HVLV) technology for dust control in the airline maintenance industry. The facility employed about 6000 workers including 22 in the carpentry panel shop, 50 in the plastics shop, 6 in the vacuum forming panel shop, and 11 in the bonding and trim shop. In these five shops, HVLV systems were installed. The design of the HVLV systems called for a vacuum capacity sufficient for 50 percent of the drops to be utilized at any time while maintaining a velocity of 10000 feet per minute in the shrouds to assure effective capture. In practice, most HVLV tool shrouds had been removed by the workers because they interfered with the jobs. The workers thought dust control was sufficiently important. They held the exhaust hose close with one hand and operated the tool with the other. Detachable shrouds for small tools had been bought but were not being used. The author concludes that the facility is familiar with HVLV systems, including detachable small tool shrouds. However, the systems are not being used in the originally intended configuration. There is a need for effective HVLV collection devices which are compatible with the work tasks while achieving a high degree of worker acceptance.
