Bromotrifluoromethane CBrF3 would have considerable potential as a closed environment fire extinguishing agent, except for its membership in that large group of hydrocarbons capable of precipitating irregular heart action when inhaled by persons with elevated levels of blood epinephrine. These experiments were an effort to determine whether myocardial metabolism was impaired in male Wistar rats breathing 7921 CBrF3O2 and challenged with 1-epinephrine in what would ordinarily constitute sub-toxic dosages. CNS effects were the major observations in rats exposed to both CBrF3 and epinephrine all control rats survived without apparent effect. The general picture was consistent with the CBrF3 induction of respiratory depression and hypoxia. Author
