The present invention relates to a method of fumigating closed systems susceptible to microbially influenced corrosion (MIC). The method is particularly useful in a method for mitigating MIC in fire protection sprinkler systems.

Method using ethylene oxide to fumigate corrosion promoting microbes

Non-flammable sterilizing gas compositions of ethylene oxide and a flame suppressant comprising pentafluoroethane and heptafluoropropane are useful in the gaseous sterilization of heat and/or moisture sensitive materials. The sterilizing gas compositions are environmentally acceptable and are more efficient and safer to use than conventional sterilant gas mixtures.

Sterilizing gas compositions of ethylene oxide, pentafluoroethane and heptafluoropropane

A method for aerating an ethylene oxide-sterilized article, said method comprising exposing said article to at least one co-adsorbate under conditions such that said co-adsorbate remains vaporized, said co-adsorbate having a partial pressure under said conditions sufficient to displace at least a portion of ethylene oxide adsorbed by said article.

Method and apparatus for aerating chemically-sterilized articles

A method of increasing the shelf life of a sterilant mixture of ethylene oxide and one or more halocarbons when the mixture is in contact with iron oxide on the surface of a storage vessel. Sufficient carbon dioxide is added to the mixture to reduce the reactivity of the iron oxide for converting ethylene oxide to reaction products of ethylene oxide. In an alternate embodiment, a hollow carbon steel vessel which holds a mixture of ethylene oxide and a halocarbon as a sterilizing gas has its inside surface passivated by forming a reaction product of iron oxide and carbon dioxide.

Shelf life improvement for ethylene oxide sterilant mixes

A sterilant mixture comprising 14 to 25 mole percent ethylene oxide and 75 to 86 mole percent 1,1,2,2,2-pentafluoroethane, and a sterilization method using same.

Sterilant mixture

A sterilant mixture comprising 15 to 30 mole percent ethylene oxide and 70 to 85 mole percent 1,1-dichloro-,2,2,2-trifluoroethane and/or 1-chloro-1,2,2,2-tetrafluoroethane, and a sterilization method using same.

Sterilization method

A sterilant mixture comprising 15 to 30 mole percent ethylene oxide and 70 to 85 mole percent 1,1-dichloro-2,2,2-trifluoroethane and/or 1-chloro-1,2,2,2-tetrafluoroethane, and a sterilization method using same.
