Título Exposure to isophorone and other organic solvents in a screen printing plant
Información bibliográfica Jan. 1982, Vol.43, No.1, p.43-48. Illus. 9 ref.
Resumen Sampling times of 50-90min were used to collect 124 charcoal tube samples from workers' breathing zones and various work areas and maximum mean time-weighted average concentrations (TWAC) of isophorone and cyclohexanone were 23 ±5.4ppm and 28 ±5ppm, respectively, at the breathing zones of printing press workers. Exposure levels for vapours such as cellosolve acetate, butyl acetate, xylenes, diacetone alcohol and petroleum distillate were also determined. Mean TWAC of personal samples were generally higher than area samples due to proximity of the solvent evaporating surfaces to the workers' breathing zones. Mean TWAC for individual vapours did not exceed OSHA limits. However, the sum of TWAC/TLV ratios of organic vapours with additive health effects exceeded unity at the breathing zones of workers handling inks and solvents. Actual 8h exposures were lower because of lower concentrations in the general atmosphere of the plant where workers spend non-active periods of the shift. Recommendations for improvement of working conditions and reduction of exposure levels.
