Sterilization refers to a process where all the living microorganisms including bacterial spores are killed. Sterilization can be done with process of physical, chemical and physiochemical means. The physical method consists of sunlight and heat. The sterilization can be done by the process of heat, irradiation, dry heat, gas vapor sterilants, ultra violet radiation, filtration like steam under the pressure and high pressure. Heat method is the most common and used method of the sterilization. The process of sterilization through heat is done by the increasing temperature of heat (Ling et al., 2018).

The heat process consists of two methods that are wet heat and dry heat. Filtration is another way of sterilization and it is very quick to done as compare to heat. The method of filtration involves the filtering in a pore size so that the microbes cannot pass through it because it is very small for the microbes. Another method of sterilization is through radiation. Radiation is a method that involves the participation of UV, gamma, X-rays to expose the packed materials for sterilization (Pan et al., 2018). Now the last method of sterilization is the chemical method. Chemical method of sterilization includes the involvement of harmful liquids and the gases that are toxic. This process has been done without affecting products while using the harmful chemicals.

Assignment 2

Sterilization packaging is a process and considered to be a device of medical. Sterilized packaging should be done very carefully as they are meant to be used in health care facilities. Packagings are sterilized to kill the microbes that are contained or present in the packages. There are three types method to done the sterilizing packages like sterilization containers, peel pouches of paper plastic and flat wrappers (Kumar et al., 2020). According to the American National Standard Institute, the criteria to follow a proper sterilization packaging are the room should be clean and the room should consist of those elements which can be cleaned easily on a regular basis. The ventilation should be there in a room in a positive presence.

There should be positive pressure of minimum exchanges of 4 airs per hour. In the room, the temperature should not exceed 75 degree Fahrenheit and the presence of humidity should also not exceed 70%. The product when it’s finally packed that should not contain more than 0.5ppm (Rutala & Weber, 2016). For the successful sterilized packaging there should be presence of Hydrogen peroxide that should be in a temperature of up to 80 degree Celsius and with the presence of the concentration up to 30% and the contact time up to 15 seconds. The process will be successful with or without any wetting substance.
