Allyl alcohol

May 1994
Immediately Dangerous to Life or Health Concentrations (IDLH)

CAS number: 107-18-6

NIOSH REL: 2 ppm (5 mg/m3) TWA, 4 ppm (10 mg/m3) STEL [skin]

Current OSHA PEL: 2 ppm (5 mg/m3) TWA [skin]

1989 OSHA PEL: 2 ppm (5 mg/m3) TWA, 4 ppm (10 mg/m3) STEL [skin]

1993-1994 ACGIH TLV: 2 ppm (4.8 mg/m3) TWA, 4 ppm (9.5 mg/m3) STEL [skin]

Description of substance: Colorless liquid with a pungent, mustard-like odor.

LEL: 2.5% (10% LEL, 2,500 ppm)

Original (SCP) IDLH: 150 ppm

Basis for original (SCP) IDLH: 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

Human data: Severe eye irritation is reported to result from exposure at 25 ppm [Dunlap et al. 1958].

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].
