HHE report: HETA-81-188-1046, Federal Correctional Institution, Miami, Florida.
NIOSH 1982 Feb; :1-15
Working conditions in the Industry Building at the Federal Correctional Institution (SIC-9223), Miami, Florida were investigated on May 12 to 14, 1981. About 40 inmates were employed to assemble electronic cables. An industrial hygiene investigation was conducted to determine if workers were adversely affected by exposure to methyl-ethyl-ketone (78933) (MEK), 1,1,1-trichloroethane (71556) (methyl-chloroform), and soldering fumes. The survey was prompted by complaints of headaches, dizziness, nausea, and related symptoms. Personal exposures were determined by collecting air samples. The highest exposures to MEK and methyl-chloroform were 89.2 and 15 parts per million (ppm), respectively. The NIOSH recommended standards for MEK and methyl-chloroform are 200ppm and 350ppm, respectively. Toluene-2,4-diisocyanate (584849) (TDI) was found in the breathing zone of one inmate at a concentration of hour time weighted average. General dilution ventilation was inadequate at the work site. Liver enzymes were elevated in three workers exposed to TDI. The author concludes that a potential health hazard did exist as a result of TDI exposure. However, the symptoms of TDI exposure are not consistent with the symptoms reported by the inmates. Elevated liver enzyme findings could not be explained.
