| Excerpts from Documentation for IDLHs |
Other animal data: A 4�hour exposure to 10,000 ppm was not lethal to rats [Smyth 1956].
Human data: Severe irritation of the throat has been reported in volunteers exposed to 300 ppm for 3 to 5 minutes [Nelson et al. 1943]. However, it has also been reported that irritation of the eyes and nose is first objectionable at 3,300 ppm and that higher concentrations cause tearing and hyperemia of the conjunctiva [Grant 1974] |
