Excerpts from Documentation for IDLHs

Basis for original (SCP) IDLH: The chosen IDLH is based on the statements by Patty [1963] and Deichmann and Gerarde [1969] that 0 rats died following a 4­hour exposure to 2,000 ppm, but 6 of 6 rats died following a 4­hour exposure to 4,000 ppm [Smyth et al. 1949]. . . . Human data: None relevant for use in determining the revised IDLH.
