This is achieved by demonstrating actual effectiveness on bacterial spores, which are generally regarded as difficult to kill. Note that autoclave tape only indicates that a certain temperature threshold has been met and therefore is not sufficient as the only indicator of sterilization.īiological indicator systems are designed to validate that an autoclave run was successful at killing microorganisms. Biological indicators, in contrast, take more time to read but measure the growth or inhibition of bacterial spores generally known to have high resistance to steam and vaporized hydrogen peroxide. They do not give an indication of how long that high temperature was held or whether the procedure was sufficient to provide adequate sterilization. Chemical indicators are quick to read, but generally, only demonstrate that the autoclave has reached a certain minimum temperature. ![]() Items purchased as sterile must be used before the expiration date, if one is given.Chemical and biological indicators are used to validate whether an autoclave is working properly.Containers used for storage of sterile instruments should be moisture resistant and cleanable.Packages should be stored at least 1 metre away from sinks, drains and moisture.Unless the instructions say otherwise, you can write on the plastic using a felt-tipped marker. Do not write on the paper side of paper/plastic pouches as the pen may puncture the paper.Handling wet or warm packages can compromise the sterility of the item. After sterilization, let the package dry thoroughly before handling.Sterile items must be cleaned and re-sterilized if the packaging is no longer sealed or in good condition.Use only packaging materials that are specifically designed for the type of sterilizer being used.Never place items onto any surface that itself is not sterile such as a tray or table. Open sterile, pre-packaged items in front of the client.A sticker can also be used with the sterilization date. Before writing, wait for the item to dry and be careful not to tear the package with your pen. The date an item is sterilized must also be written on the package. These records must be on site for one year and on file for five years. You must write down the date, time, duration, amount of equipment, temperature, pressure and the person who is responsible for the sterilization load. Physical monitoring means keeping a record for each load. It does not tell you if the instrument was sterilized properly. The indicator will change colour if the instrument has gone through a cycle in the autoclave. This means that all instrument packages must have a heat sensitive indicator on the outside. The business moves to a new fixed location.Ĭhemical monitoring must be done every time you use the autoclave.The autoclave has not been in use for more than 2 weeks.Three consecutive spore tests must be conducted if: **Do not use sterilized items or instruments until AFTER you receive the passed (negative) spore test results** Keep copies of the spore test results on site for a year and on file for 5 years. A failed (positive) spore test means the sterilizer is not working properly. ![]() A passed (negative) spore test means the sterilizer is working properly. You must send the strip tests to a laboratory for testing. There are three types of monitoring that is required biological, chemical and physical.īiological monitoring (spore testing) must be done every 2 weeks. ![]() Autoclaves must be monitored to ensure they are working properly.All items must be packaged before being sterilized.An ultrasonic cleaner can be used to clean instruments before sterilization. Any item being sterilized must first be cleaned.
