Excerpts from Documentation for IDLHs

Basis for original (SCP) IDLH: The chosen IDLH is based on the statements by Patty [1963] that 10,670 ppm for 225 minutes and 16,000 ppm for 160 minutes were fatal for mice [Weese 1928]. According to Patty [1963], at 20,000 ppm it took 12 to 20 minutes to produce prostration in mice and 40 minutes to produce narcosis; no deaths occurred [Starrek 1938]. The chosen IDLH is probably conservative.
