Insufficient data
Excerpts from Documentation for IDLHs
Other animal data: Cats exposed to 10 ppm for 20 min died within ten days [Flury and Zernik 1931]. It has been reported that cats exposed to 7 to 25 ppm for periods ranging from 2.5 to 5 hours died within 1 to 5.5 hours [Sievers et al. 1947]. . . . Human data: It has been stated that concentrations above 5 ppm may cause irreversible lung and systemic damage [Koelsch 1917].
