Abstract
In response to a request from a management representative of Patio Enclosures, Inc. (SIC-3442), Macedonia, Ohio, an environmental survey was conducted in the 700 and 720 office buildings of Patio Enclosures. Personnel working at the site had complained of eye problems, burning of the throat, and sinus problems. Patio Enclosures consisted of a large manufacturing area with two story office areas at the east and west ends. Average temperatures in the office ranged from 69.2 to 74.9 degrees-F during the morning and from 69.1 to 75.3 degrees in the afternoon. Average relative humidity ranged from 15.0 to 21.2% during the morning and 18.0 to 23.3% in the afternoon. Average carbon-dioxide (124389) concentrations ranged from 375 to 850 parts per million (ppm) in the morning and 500 to 850ppm in the afternoon. Visible microbial growth was present in some of the air handling unit drip pans. Analysis revealed several species such as Penicillium, Cladosporium, Aspergillus, Alternaria, yeasts, Ulocladium, and Fusarium. Smoking was permitted in the private offices which then circulated to other areas served by the same units. The author concludes that a potential health hazard existed due to the recirculation of environmental tobacco smoke throughout the offices. Microbial growth in the ventilation system could be aerosolized and distributed throughout the building. The author recommends that a no smoking policy be established, and cooling coil condensate pans and drains be cleaned.
