... Massive exposure to fumes may occur during transportation accidents, but the development of treatment procedures has resulted in low incidences of morbidity and mortality in industrial operations, as opposed to nonindustrial exposures (ACGIH, 1980; Lawson, 1981; Stecher et al., 1968; Ploysongeang et al., 1982~.

... Pathologic examination of rats exposed at 9 ppm showed gross evidence of infIa~matory reactions of the upper and lower respiratory tract, including hyperemia and accumulation of inflammatory material in the nasal passages. There were also various degrees of pulmonary ateJectasis or consolidation.

... Having reviewed available toxicity data on chlorine, the Committee believes that no compelling new information warrants revision of the previously established 60~in EEL and 90 CEL. However, on the basis of human data that suggest sensory irritation and changes in pulmonary function as results of B-h exposure to chlorine at 1 ppm, the Committee believes that the 24-h EEL should be lowered to 0.5 ppm.
