Adequate exposure period that will provide for complete penetration of the load and insure destruction of microbial life with a liberal margin of error. Steam Sterilization Advantages Destruction of most resistant bacterial spores with relatively brief exposure. Easy control of lethality for various materials and supplies. Not toxic residue and materials following sterilization process Most economical method. Disadvantages Incomplete air elimination from sterilizer depresses temperature and prevent sterilization.
Air is a stubborn opponent to the diffusion and expansion of steam.
Possible superheated steam with diminished microbial power if sterilizer is used incorrectly. Unsuitable method for sterilization of anhydrous oils, greases and powders. There are many trade names for the wide variety of disinfectants. The degree of success achieved with chemical decontaminants may range from minimal inactivation of the target microorganism to sterility depending upon how these factors are manipulated. No single chemical disinfectant or method will be effective or practical for all decontamination situations.
