Walk-Through Survey Report, Control Technology for Grinding and Cutting at Fairchild Republic Co., Farmingdale, New York

摘要

A walk through survey was conducted at the Fairchild Republic Company (SIC-3729), in Farmingdale, New York, on March 25, 1983 to determine the state of the art of high velocity low volume (HVLV) technology in grinding, sawing, sanding, and drilling aluminum (7429905), resins, and fiberglass. Hazards identified were total dusts, resin dusts and fibers, and fiberglass dust and fibers. HVLV systems had been installed in each of the three areas, but were not being used as they were designed to be used. In area 1, the shroud was removed and the flexible duct was fastened to the workpiece. Area 2 and area 3 did not use the shroud at all. The author notes that a full observation of the difficulties reported in the HVLV system was not possible, but that the hoods had not been used for some time. The authors conclude that the perceived encumbrance of the vacuum hose and tool shrouds has resulted in their disuse. Improvements are needed in the HVLV design to achieve complete implementation of the control system. Further observations should be made to determine suitability of HVLV hoods.
