    摘要: Non-ozone depleting sterilant compositions made of ethylene oxide and 1,1,1,2,3,3,3-heptafluoropropane. These compositions provide good sterilization characteristics, and are compatible with contemporary environmental concerns. One preferred aspect of the invention is a sterilant mixture comprising from about 20 mole percent to about 35 mole percent ethylene oxide and from about 65 mole percent to about 80 mole percent HFC-227 ea. Compositions comprising from about 25 mole percent to about 30 mole percent ethylene oxide and from about 70 mole percent to about 75 mole percent HFC-227 ea are preferred, with a composition comprising about 27 mole percent ethylene oxide and about 73 mole percent HFC-227 ea being most preferred.

    摘要: A method for delivering a liquid fire suppression composition to a fire includes storing the fire suppression composition and a pressurized gas in separate containers, detecting the occurrence of a fire to be suppressed, within about 60 seconds of detecting the fire coupling the pressurized gas with the fire suppression composition to superpressurize the composition, and emitting the superpressurized fire suppression composition to the fire. The method is particularly adapted for use in a total flooding system.
