Immediately Dangerous to Life or Health Concentrations (IDLH)

Sulfur monochloride

CAS number: 10025–67–9

NIOSH REL: 1 ppm (6 mg/m3) CEILING

Current OSHA PEL: 1 ppm (6 mg/m3) TWA

1989 OSHA PEL: 1 ppm (6 mg/m3) CEILING

1993-1994 ACGIH TLV: 1 ppm (5.5 mg/m3) CEILING

Description of substance: Light-amber to yellow-red, oily liquid with a pungent, nauseating, irritating odor.

LEL: . . Unknown

Original (SCP) IDLH: 10 ppm

Basis for original (SCP) IDLH: Very little data are available on which to base the IDLH for sulfur monochloride. The chosen IDLH has been estimated from the statement by ACGIH [1971] that 12 ppm for 15 minutes was tolerated by cats, but four times that concentration, also for 15 minutes, could lead to death after a few days [Flury and Zernik 1931]. No other useful data are available on which to base the IDLH.

Short-term exposure guidelines: None developed

Other animal data: It has been reported that cats have tolerated 15-minute exposures to 12 ppm, while 48 ppm could lead to death after a few days [Flury and Zernik 1931].

Human data: None relevant for use in determining the revised IDLH.

 

Revised IDLH: 5 ppm

Basis for revised IDLH: The revised IDLH for sulfur monochloride is 5 ppm based on acute inhalation toxicity data in animals [Flury and Zernik 1931; Henderson and Haggard 1943].
