Health hazard evaluation determination report: HHE-79-54-578, Horizon House Institute for Research and Development, Philadelphia, Pennsylvania.
NIOSH 1979 Apr; :1-6
Environmental and medical evaluations were conducted on February 27 and 28, 1979 at the Horizon House Institute for Research and Development (SIC-8922) in Philadelphia, Pennsylvania in response to a request from an authorized employee representative to determine a possible hazard to approximately five employees from exposure to unknown odors in the workplace. Direct reading instruments were used to evaluate environmental conditions and to check for airborne contamination from carbon-monoxide (630080), carbon-dioxide (124389), oxides of nitrogen, ozone (10028156), and total organic vapors. Each employee was given a non-directive medical questionnaire to complete. No toxic exposures to any of the contaminants were found. The kitchen exhaust was not functioning and was allowing odors to downdraft into the work area, and gas stove pilot lights were emitting a slight gas odor. Relatively high temperatures (80 degrees-F), low relative humidity (approximately 15 percent), and borderline inadequate lighting (45 to 60 footcandles) were observed. Three employees reported adverse health effects. The author concludes that no toxic agents were present to account for the alleged health effects, but environmental conditions could have produced the reported symptoms. The repairing of exhaust ventilation, lowering of room temperatures, use of brighter lighting, and installation of a portable humidifier are recommended by the author.
