Immediately Dangerous to Life or Health Concentrations (IDLH)
**CAS number:** 7803–52–3
**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
**1993-1994 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].
**Short-term exposure guidelines:** None developed

 **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].**REFERENCES:**
