Excerpts from Documentation for IDLHs
Basis for original (SCP) IDLH: The chosen IDLH is based on the following statements: A 4­hour exposure to 8,000 ppm killed 4 of 6 rats [UCC 1971; Smyth et al. 1962 as cited by ACGIH 1971] and no deaths resulted from a 4­hour exposure of 6 rats to 4,000 ppm [UCC 1971; Smyth 1964 as cited by ACGIH 1971]. . . . Human data: None relevant for use in determining the revised IDLH.
