• Description:
  The state of the art of high velocity low volume (HVLV) technology and its successful application was surveyed on March 21, 1983 at Haveg (SIC-3079), Wilmington, Delaware. The facility employed 15 to 20 workers in the machine shop and fabrication activities. The company produced a molded corrosion resistant plastic by mixing viscous liquid phenolic or furfuryl alcohol resins with fiber filler and reinforcing agents. The potential hazard in machining the plastic was associated with dust and fibers. The HVLV exhaust system was originally designed to meet the OSHA asbestos criteria of two fibers per cubic centimeter. It has been maintained and operated to control the dust. Suction was maintained by two 150 horsepower blowers. The system had 35 to 40 attachment points, 7 of which were located at hand tool stations. The system supported 16 active outlets simultaneously. The joints in the duct piping were replaced periodically due to wear of abrasive materials in the high velocity air stream. Disposable dust masks were available to workers during dusty jobs. Other unique practices included the use of improvised deflectors to aid the HVLV pickup of material during lathe operations. Management expressed overall satisfaction with the HVLV system.
