NIOSH REL: 3 ppm (14 mg/m3) TWA, 6 ppm (28 mg/m3) STEL
Current OSHA PEL: 3 ppm (13.5 mg/m3) TWA
1989 OSHA PEL: 3 ppm (14 mg/m3) TWA, 6 ppm (28 mg/m3) STEL
1993-1994 ACGIH TLV: 3 ppm (13 mg/m3) TWA, 6 ppm (25 mg/m3) STEL
Description of substance: Colorless gas with a characteristic, sweet odor.
LEL: . . Nonflammable Gas
Original (SCP) IDLH: 385 ppm
Basis for original (SCP) IDLH: The chosen IDLH is based on the rat 4hour LC50 of 385 ppm [Greene et al. 1960 cited by ACGIH 1971].
Short-term exposure guidelines: None developed
ACUTE TOXICITY DATA:
Lethal concentration data:
| Rat
Rat Mouse Dog | Dost et al. 1974 Greene et al. 1960 Greene et al. 1960 Jacobson 1958 |

Human data: None relevant for use in determining the revised
IDLH.
| Revised IDLH: 100 ppm
Basis for revised IDLH: The revised IDLH for perchloryl fluoride is 100 ppm based on acute inhalation toxicity data in animals [Greene et al. 1960; Jacobson 1958]. |
