In a survey in March 1985, concentrations of hydrochloric acid, sulfuric acid, sodium hydroxide, propylene oxide, and total and respirable starch dust were all below acceptable limits. « lessĪ request for an investigation of pulmonary and cardiovascular disease was received from the National Starch and Chemical Corporation, Indianapolis, Indiana. The authors recommend specific measures to reduce exposures. The authors conclude that a health hazard existed due to overexposures to total particulates, mixtures of organic solvents and to coal-tar paint containing polynuclear aromatic hydrocarbons. The seven sanding employees reported no symptoms associated with their occupations. Among the painters these symptoms coincided with the use of the bitumastic coal-tar paint. A medical questionnaire administered to nine employees revealed occasional eye and upper respiratory irritation. Polynuclear aromatic hydrocarbons ranged up to 4.1 micrograms/cubic meter.

Total more » particulates ranged from 5.1 to 36.3mg/cu m, compared to an exposure criteria of 10mg/cu m. One worker had potential overexposures to solvents based on the additive effect of the solvent vapor mixtures although the worker wore a respirator, the protection afforded using the respirator was inadequate. The measured concentrations of individual solvents were below NIOSH and ACGIH recommended levels and OSHA standards.

The facility was involved in manufacturing custom fire trucks, and had 125 production workers. In response to a request from the United Steel Workers of America, Local 2166, an evaluation was made of employee exposures in the primer parts spray paint booth and sanding area of the FMC Corporation (SIC-7535), Tipton, Indiana.
