Sulfuryl fluoride																				Related Pages
										May 1994
Immediately Dangerous to Life or Health Concentrations (IDLH)
**CAS number:** 2699–79–8
**NIOSH REL:** 5 ppm (20 mg/m3) TWA, 10 ppm (40 mg/m3) STEL
**Current OSHA PEL:** 5 ppm (20 mg/m3) TWA
**1989 OSHA PEL:** 5 ppm (20 mg/m3) TWA, 10 ppm (40 mg/m3) STEL
**1993-1994 ACGIH TLV:** 5 ppm (21 mg/m3) TWA, 10 ppm (42 mg/m3) STEL
**Description of substance:** Colorless, odorless gas.
**LEL**: Nonflammable Gas
**Original (SCP) IDLH:** 1,000 ppm
**Basis for original (SCP) IDLH:** The chosen IDLH is based on the report by Taxay [1966] that less than 5% mortality resulted from exposure of animals for 3 hours to 1,000 ppm.
**Short-term exposure guidelines:** None developed

 **Human data:** None relevant for use in determining the revised IDLH.
 
 **Revised IDLH:** 200 ppm **Basis for revised IDLH:** The revised IDLH for sulfuryl fluoride is 200 ppm based on acute inhalation toxicity data in animals [Nitschke et al. 1986; Truhaut et al. 1973].**REFERENCES:**
