HHE Report No. HETA-83-409-1450, King Kwik Minit Market, Inc., Cincinnati, Ohio.
NIOSH 1984 Apr:10 pages
In response to a request from the management of King Kwik Minit Markets (SIC-5411), located in Cincinnati, Ohio, an investigation into complaints of itching and localized rash occurring in workers was made. The study was directed toward the data processing computer room which had a 100 percent recirculating air handling system. The system used an unlined high density fibrous glass duct system with flexible metal lined air ducts connected to ceiling supply vents. Polyester filters were located in all of the supply air openings. The problems developed after startup of the room's air conditioning system following an inadvertent 30 to 45 minute shutdown to service one of the building's other air conditioning units. All seven computer room workers and two accounting department workers who handled computer room printouts were affected. Symptoms, which had persisted over a 5 month period, diminished if workers showered and changed clothes after leaving work. Glass fibers (14808607) were identified on three tape samples taken from exposed skin areas (two currently symptomatic) and on one sample taken from a computer printout. No glass fibers were detected in air or surface samples nor in vacuum samples from a stack of computer paper and a small hood over the printer paper discharge. The authors conclude that the outbreak is consistent with fibrous glass dermatitis, but a possible source of exposure cannot be identified. They recommend that the computer room be completely cleaned, that added precautions be taken during any maintenance of fibrous glass duct work, and that a regularly maintained dehumidifying system for introducing outside air into the computer room be considered.
