HHE report no. HETA-89-220-2191, Hertz Car Rental, Chicago, Illinois.
NIOSH 1992 Mar; :1-24
In response to a request from employees at a Hertz Car Corporation (SIC-4119) building near Chicago's O'Hara International Airport, an investigation was undertaken of possible hazardous working conditions at the site. The Hertz building was a single story concrete, block, and glass construction. Indoor temperature measurements ranged from 72 to 75 degrees-F. Indoor humidity measurements averaged 47 to 52%. Most of the indoor carbon-dioxide (124389) (CO2) measurements on the day of the survey were 600 parts per million (ppm). A study of the ventilation system in place at the company suggested that it could have resulted in some of the complaints. Several possible bioaerosol sources were found in the outside air duct, supply duct lining, and a computer room cooling unit and furnishings. The authors conclude that complaints appear to be due to thermal comfort and bioaerosol problems. The authors recommend measures to improve conditions in the facility.
