Certification is usually accomplished utilizing instrumentation, chemical indicators, and biological indicator to verify that appropriate physical parameters are satisfactory and that resistant microorganisms are destroyed. It is highly recommended that biological indicators be used rather than those chemical temperature. 3. Chemical indicators are of limited value in verifying the decontamination of biohazardous waste. Chemical indicator inks printed on waste packaging materials inteneded for autoclaving provides a color change that serves only to distinguish treated waste from waste requiring treatment, i.e., failure of an indicator to change to its signal color after the process demonstrates immediately that the equipment has malfunctioned. Temperature indicator strips that change color indicates only that the outside of the container was exposed to a certain temperature, they do not indicate internal temperature or exposure times and therefore, do not indicate that the waste has been sterilized. They do indicate, however, processing time rather than treatment effectiveness. 4. A recording thermometer must be used to ensure that a sufficiently high temperature is maintained for an adequate time during the cycle. Failure to attain or maintain operating temperature may indicate mechanical failure. . 5. It is highly recommended that each load contain a biological indicator (Bacillus sterarotheromphilus) to determine that the autoclaved biological wastes have been sterilized at proper temperature, time and pressure. 1. Biological commodities requiring registration must be autoclaved in the primary laboratory unless otherwise authorized.. 2. All commodities being autoclaved must be accompanied on a quarterly basis by a biological and each cycle by a time/thermal or color indicator and must be placed in the autoclave by a member of the responsible group will see that temperature and pressure is up to desired levels and the unequivocal instructions for sterilization are posted before leaving the area. 3. Contaminated dead animals, animal wastes or tissues wastes must be placed into sealed, properly labeled, doubled plastic bags, and put into a lidded leak proof, metal container prior to autoclaving. 1. All commodities must be delivered in a lidded, leak proof, secondary container and each secondary container must be so labeled as to indicate the laboratory of origin, the most hazardous microorganism present and that the material has not been autoclaved. 2. If biological commodities requiring registration are involved, a member of the responsible research group delivering the material to be autoclaved must place the secondary container in the autoclave. file://C:\Documents and Settings\Owner\My Documents\P&PUnfection Control 2005\Bioha... 5/5/2005
