Health hazard evlauation report: HETA-81-161-952, Public School 397, Brooklyn, New York.
Cincinnati, OH: U.S. Department of Health and Human Services, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, HETA 81-161-952, 1981 Sep; :1-7
Environmental measurements of temperature, relative humidity, air movement, carbon-monoxide (630080), carbon-dioxide (124389), formaldehyde (50000), and organic vapors were taken on March 31,1981 at Public School 397 (SIC-8211) in Brooklyn, New York. A representative of the United Federation of Teachers, Local 2, requested the evaluation on behalf of approximately 550 teachers and students. Employee medical interviews were also conducted. All measured concentrations of carbon-monoxide, carbon-dioxide, and formaldehyde were substantially below the OSHA standards of 50, 500, and 3 parts per million (ppm), respectively. No hydrocarbons were detected. Overall air supply was adequate although air movement at desk top level was low. Relative humidity was slightly below the comfort level. Medical interviews indicated widespread complaints of stale air and respiratory irritation due to dust from classroom carpets. The authors conclude that a health hazard from toxic substances did not exist at this facility. They recommend the vacuuming of classroom rugs, modifications to increase air circulation, and extension of the school's chimney to increase dispersion of the chimney's effluents.
