42 Biosafety Manual • Autoclaves and pressure vessels without the ASME identification plate may continue to be used at their installed location as long as they are in good condition and are inspected for safety at least annually (automatically scheduled each year). They can never be unhooked and installed at a different location. • Inspect your autoclave components regularly. Do not operate an autoclave until it has been repaired. Repair or service of autoclaves on campus can be requested by calling Facilities Planning and Management at (515) 294-5100 unless the autoclave is under a special service contract. In this case, the service provider must be contacted. Chemical Disinfectants Items that cannot be autoclaved can generally be decontaminated using a chemical disinfectant. Choosing the appropriate chemical disinfectant depends on the surface or item needing decontamination, as well as the particular organism requiring inactivation. Choosing a Chemical Disinfectant When choosing a chemical disinfectant, review the Pathogen Safety Data Sheet (PSDS) of the Public Health Agency of Canada (if available) for the agent needing inactivation, the categories of disinfectants listed in this section, and the disinfectant product label. Personnel in the process of choosing a disinfectant must also keep the following considerations in mind: • How effective is the disinfectant for the particular application? ¤ What is the organism requiring inactivation? (Different disinfectants are more effective against different types of organisms.) ¤ How many of the organisms are present? (The more organisms present, the more disinfectant required and/or the longer the application time will be.) • What needs decontamination? (The disinfectant must be compatible with the item to be decontaminated.) ¤ Work surfaces (for example, metal, tile, plastic, wood, concrete) ¤ Glassware ¤ Equipment (such as biosafety cabinet, surgical tools, cages)
