The chosen IDLH is based on the statement by AIHA [1963] that from animal experiments, a single 1-hour exposure to 150 ppm might be fatal, while the same exposure to 100 ppm would probably allow survival [Dunlap et al. 1958]. Short-term exposure guidelines . None developed

Revised IDLH: 20 ppm
Basis for revised IDLH: The revised IDLH for allyl alcohol is 20 ppm based on
acute inhalation toxicity data in humans [Dunlap et al. 1958] and animals
[Dunlap et al. 1958; Smyth and Carpenter 1948].
