Allyl chloride

May 1994

Immediately Dangerous to Life or Health Concentrations (IDLH)

CAS number: 107-05-1

NIOSH REL: 1 ppm (3 mg/m3) TWA, 2 ppm (6 mg/m3) STEL

Current OSHA PEL: 1 ppm (3 mg/m3) TWA

1989 OSHA PEL: 1 ppm (3 mg/m3) TWA, 2 ppm (6 mg/m3) STEL

1993-1994 ACGIH TLV: 1 ppm (3 mg/m3) TWA, 2 ppm (6 mg/m3) STEL

Description of substance: Colorless, brown, yellow, or purple liquid with a pungent, unpleasant odor.

LEL: 2.9% (10% LEL, 2,900 ppm)

Original (SCP) IDLH: 300 ppm

Basis for original (SCP) IDLH: The chosen IDLH is based on the statement by Deichmann and Gerarde [1969] that a 1-hour exposure to 300 ppm might cause serious effects.

Short-term exposure guidelines: None developed

Rabbit	Boqin et al. 1982	22,500 mg/m3	—–	2 hr	8,844 ppm (1.25)	884 ppm
Cat	Boqin et al. 1982	10,500 mg/m3	—–	2 hr	4,127 ppm (1.25)	413 ppm

Human data: It has been stated that a 1-hour exposure to 300 ppm might cause serious effects [Deichmann and Gerarde 1969].

Revised IDLH: 250 ppmBasis for revised IDLH: The revised IDLH for allyl chloride is 250 ppm based on acute inhalation toxicity data in humans [Deichmann and Gerarde 1969] and animals [Boqin et al. 1982].
