Abstract
The authors respond to comments by K. E. Robinson (see NIOSHTIC record NIOSH-00241874) on their article entitled Hazards At Your Auto Dealership (Including Everything You Ever Wanted to Know About a Tail-Pipe Exhaust System) (Applied Occupational and Environmental Hygiene, Vol. 12, No. 12, page 781; see NIOSHTIC record NIOSH- 00236400). Due to various factors enumerated, efforts to obtain exhaust fan curves, design criteria, technical manuals, and maintenance records for the 20 year old facility were unsuccessful. Based on visual inspection using a 24 foot extension ladder, the decrease in static pressure was not due to belt condition, direction of rotation, inlet or outlet design, or obstructions at the outlet. The drive belts appeared to be in good condition and the fan inlet and outlet were installed adhering to typical fan guidelines. Sizing the pulleys would not have provided any useful information as the rated fan speed was not available. Due to the lack of information available in evaluating the exhaust fan, it was recommended that the existing fan be replaced by one with the recommended flow rate and static pressure at a cost of less than five hundred dollars. Operating specifications, documents, and other pertinent information would then be available.
