• Description:
  A walk through survey was conducted to evaluate the application of High Velocity Low Volume (HVLV) technology at the Kenworth Truck Company (SIC-3711, SIC-3713) in Seattle, Washington on June 8, 1983. The HVLV systems were installed to reduce employee exposures to nuisance dust. The system consisted of a vacuum with ceiling drops connected to the tools by a flex hose. Sanding was performed in front of filtered lateral exhaust plenums. A ventilated enclosure was provided for gelcoat activity, and chopped fibers were applied in ventilated booths. The employees preferred air hoods or respirators to the cumbersome exhaust hoses and tools. The HVLV sander was too large and too slow. Personal exposure measurements were lower when the HVLV was used. Nuisance dust concentrations were below the limit of 10 milligrams per cubic meter even without the use of HVLV sanders. The author notes that the plastic shop ventilation system was recognized by OSHA as exemplary. The authors conclude that the facility is a good candidate for HVLV system operation demonstration.
