Excerpts from Documentation for IDLHs |
Human data: It has been reported that 5.5 ppm results in intense irritation and marked lacrimation, after 60 seconds [Henderson and Haggard 1943]. Exposures to 1.8 ppm result in slight eye irritation after 1 minute and profuse lacrimation after 4 minutes [NRC 1981]. In volunteers exposed for 5 minutes, concentrations of 2 to 2.3 ppm produced severe irritation [Darley et al. 1960]. A 10-minute exposure at 8 ppm and a 5-minute exposure at 1.2 ppm elicited extreme irritation described as "only just tolerable" [Sim and Pattle 1957]. |
