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


Lethal concentration data:

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.
