Allyl Glycidyl Ether

May 1994

Immediately Dangerous to Life or Health Concentrations (IDLH)

CAS number: 106-92-3

NIOSH REL: 5 ppm (22 mg/m3) TWA, 10 ppm (44 mg/m3) STEL [skin]

Current OSHA PEL: 10 ppm (45 mg/m3) CEILING

1989 OSHA PEL: 5 ppm (22 mg/m3) TWA, 10 ppm (44 mg/m3) STEL

1993-1994 ACGIH TLV: 5 ppm (23 mg/m3) TWA, 10 ppm (47 mg/m3) STEL

Description of substance: Colorless liquid with a pleasant odor.

LEL: Unknown

Original (SCP) IDLH: 270 ppm

Basis for original (SCP) IDLH: The chosen IDLH is based on the mouse 4-hour LC50 of 270 ppm [Hine et al. 1956] cited in ACGIH [1971], AIHA [1965], and Patty [1963].

Short-term exposure guidelines: None developed

ACUTE TOXICITY DATA

Lethal concentration data:

					Adjusted
		LC50	LCLo		0.5-hr	Derived
Species	Reference	(ppm)	(ppm)	Time	LC (CF)	Value
Mouse	Hine et al. 1956	270	—–	4 hr	540 ppm (2.0)	54 ppm
Rat	Hine et al. 1956	670	—–	8 hr	1,675 ppm (2.5)	168 ppm

Human data: None relevant for determining the revised IDLH.

Revised IDLH: 50 ppmBasis for revised IDLH: The revised IDLH for allyl glycidyl ether is 50 ppm based on acute inhalation toxicity data in animals [Hine et al. 1956]. This may be a conservative value due to the lack of relevant acute toxicity data for workers.
