Abstract : It is believed that atmospheres can be developed which will not support combustion of ordinary materials such as paper, plastics, solvents, etc., and in which humans will be able to live and function normally for extended periods of time. Such atmospheres would contain relatively small amounts (10-20%) of certain fully-fluuorinated agents (CF4, C2F6, or C3F8) added to air. The presence of the agents would completely suppress the burning of materials, but because they are physiologically inert and present in small concentration, they would not appreciably affect the life support process. The objective of the present study was to evaluate the avalidity of this concept. The toxicity tests included acute and ten-day inhalation studies on rats and guinea pigs and cardiac sensitization tests on dogs (with CF4). (Author)
