Walk Through Survey Report of General Dynamics, Fort Worth, Texas

摘要

A walk through survey was conducted to evaluate painters' exposures to glycol ethers at the General Dynamics military aircraft manufacturing facility (3721), Fort Worth, Texas. Personal breathing zone exposures to airborne 2-ethoxyethyl-acetate (111159) (2-EEA) averaged 1.30 parts per million (ppm). The highest individual exposure was 6ppm. The current OSHA standard is 100ppm. Results of two surveys of major painting areas indicated that painters' exposures to 2-EEA ranged from 0.48 to 2.8ppm, from 0.1 to 7.49ppm, and from 1.5 to 12.1ppm in the three areas. Due to the use of respiratory protection by many of the painters, actual inhalation exposures were undoubtedly much lower than the breathing zone measurements. Some exposure may have been incurred through skin absorption. The authors recommend that an additional industrial hygiene survey, including urine monitoring and air monitoring should be carried out in order to obtain a better estimate of total exposure to 2-EEA.
