IDLH Documentation
CAS number: 7803­52­3

NIOSH REL: 0.1 ppm (0.5 mg/m3) TWA

Current OSHA PEL: 0.1 ppm (0.5 mg/m3) TWA

1989 OSHA PEL: Same as current PEL

1993­1994 ACGIH TLV: 0.1 ppm (0.51 mg/m3) TWA

Description of substance: Colorless gas with a disagreeable odor like hydrogen sulfide.

LEL: . . . Unknown

Original (SCP) IDLH: 40 ppm

Basis for original (SCP) IDLH: The chosen IDLH is based on the statement by AIHA [1960] that exposure of dogs and cats to 40 to 45 ppm for 1 hour has proven dangerous [Webster 1946].

Short­term exposure guidelines: None developed

Other animal data: It has been reported that exposure of dogs and cats to 40 to 45 ppm for 1 hour has proven dangerous [Webster 1946].

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

Revised IDLH: 5 ppm

Basis for revised IDLH: The revised IDLH for stibine is 5 ppm based on acute inhalation toxicity data in animals [Browning 1961].
