Thus, sterilization by moist heat will not work for all products, especially products containing electronics or flexible plastics. It is effective in killing fungi, bacteria, spores, and viruses but does not necessarily eliminate prions. Sterilization by moist heat Moist heat occurs in the form of hot water, boiling water, or steam (vaporized water). The methods are: 1. 13.4 Depending on the size of the container, it may be necessary to perform initial container mapping studies with temperature sensing devices placed inside the product container to identify its heat penetration characteristics and to determine the container "cold spot". 20-22. Heat and moist heat were applied in different groups either immediately after exercise or 24 hours later. Moist heat sterilization mechanism in sterilizing the equipment and pharmaceutical products is the denaturation of the microorganism's proteins structure and the enzymes of microorganisms present on the equipment or pharmaceutical product and thus killing them. Moist heat causes destruction of micro- organisms by denaturation of macromolecules, primarily proteins. 13.3 Heat penetration studies should be conducted with the maximum and minimum loading configurations for each sterilization cycle using the sterilization parameters specified for the normal production cycles. Process requires. All changes to the sterilizer system or process must be pre-authorized through the change control system or be required as part of a pre-established maintenance program. If you accept and continue, it means that you are happy with it. 16.4 Requalification is performed according to detailed written procedures which require that the original validation parameters and limits be used as evaluation criteria. See reference 1, 2, 3, 4, 5, 6, 7 for a discussion of how biological indicators can be used during a sterilization cycle to obtain an estimation of "F0" values. These studies are conducted to ensure that the coolest unit within a pre-defined loading pattern (including minimum and maximum loads) will consistently be exposed to sufficient heat lethality (minimum "F0"). The devices should be capable of simultaneous data generation within pre-established time intervals in order to permit determination of the slowest and fastest heating zones in the chamber. Information and data in support of. If no processing error is discernable, the process is judged unacceptable. It does not apply to products sterilized by filtration, radiation, dry heat, or ethylene oxide.. Post-sterilization is a depressurization stage where steam is replaced by air.
