| Description |
Colorless to water-white, nearly odorless liquid or gas (above 75 degrees F); [NIOSH] |
|---|
| Sources/Uses |
CFC-11 has been used as a blowing agent, a refrigerant, and an aerosol propellant. [ACGIH] Used in photography (film cleaner); [www.ci.tucson.az.us/arthazards/medium.html] |

| Comments |
Fluorotrichloromethane is in the list of "Some volatile substances which may be abused by inhalation" published on the web site of the U.N. International Drug Control Programme, indicating its potential to cause narcosis in workers. [Reference #1] Evaporating liquid can cause frostbite; Inhalation of high concentrations can cause CNS depression and cardiac arrhythmias; [ICSC] |

| Excerpts from Documentation for IDLHs |
Evidence of serious arrhythmia was noted in 1 of 12 conscious dogs exposed for 5 minutes to 5,000 ppm plus intravenous epinephrine [Reinhardt et al. 1971]. However, in another study, endogenous epinephrin was not sufficient to precipitate arrythmia in dogs exposed to 5,000 to 10,000 ppm [Reinhardt et al. 1971]. |
