CAS number: 509148
NIOSH REL: 1 ppm (8 mg/m3) TWA
Current OSHA PEL: 1 ppm (8 mg/m3) TWA
1989 OSHA PEL: Same as current PEL
19931994 ACGIH TLV: 0.005 ppm (0.04 mg/m3) TWA, A2
Description of substance: Colorless to paleyellow liquid or solid (below 57°F) with a pungent odor.
LEL :. . Unknown
Original (SCP) IDLH: 5 ppm
Basis for original (SCP) IDLH: The chosen IDLH is based on the statement by AIHA [1964] that concentrations above 5 ppm may cause irreversible lung and systemic damage [Koelsch 1917]. Patty [1963] reported that a cat exposed to 10 ppm for 20 minutes died within 10 days [Flury and Zernik 1931], and 5 cats exposed to 7 to 25 ppm for periods ranging from 2.5 to 5 hours died within 1 to 5.5 hours [Sievers et al. 1947].
Shortterm exposure guidelines: None developed

Other animal data: Cats exposed to 10 ppm for 20 min died within ten days [Flury and Zernik 1931]. It has been reported that cats exposed to 7 to 25 ppm for periods ranging from 2.5 to 5 hours died within 1 to 5.5 hours [Sievers et al. 1947].
Human data: It has been stated that concentrations above
5 ppm may cause irreversible lung and systemic damage [Koelsch
1917].
Revised IDLH: 4 ppm
Basis for revised IDLH: Based on acute inhalation toxicity data in humans [Koelsch 1917] and animals [Horn 1953; Kinkead et al. 1977], the revised IDLH for tetranitromethane is 4 ppm. |
