Excerpts from Documentation for IDLHs
Basis for original (SCP) IDLH: The chosen IDLH is conservative, but the only data available on which to base the IDLH is the statement by Patty [1963] that Smyth [1956] found rats survived when exposed for 4 hours to 8,000 ppm. The IDLH for isobutyl alcohol is also 8,000 ppm. . . . Human data: It has been reported that corneal irritation was occasionally observed in workers exposed to 200 ppm [Sterner et al. 1949].
