Walk-Through Survey Report: HVLV (High Velocity Low Volume) Control Technology for Auto Body Shop Sanding at Kay Parks Autobody Rebuild Inc., Tacoma, Washington

摘要

A walkthrough survey was conducted to assess the effectiveness of high velocity low volume (HVLV) technology at Kay Parks Autobody Rebuild, Inc. (SIC-7531), in Tacoma, Washington on June 9, 1983. The employees were observed using the vacuum system for housekeeping tasks as well as HVLV sanders. Coveralls and caps were worn, as were face masks and spray paint cartridge respirators. No dust monitoring was performed, but the shop was cleaner than most other auto body shops. Resuspension of dust was prevented by the use of a vacuum attachment to clean sanded parts rather than blowing with compressed air. A video tape was made of the facility and of the dust collection efficiency. There was a remarkable visible difference with and without the HVLV vacuum hose attached. The author concludes that the innovative system developed by the owner provides valuable information for other businesses that might benefit from using a HVLV control system.
