There are generally three levels of decontamination: cleaning, disinfection, and sterilization. Cleaning involves removing dirt and impurities, disinfection reduces or eliminates pathogens on surfaces, and sterilization destroys all forms of microbial life, including spores. Each level is appropriate for different situations based on the type of contamination and the required level of safety.

lowest level of Decontamination
Decontamination generally involves three main types: cleaning, disinfection, and sterilization. Cleaning removes dirt and organic matter, while disinfection eliminates most pathogens but may not kill all spores. Sterilization, the most thorough method, destroys all forms of microbial life, including spores. Each type is used based on the level of contamination and the required safety standards for specific environments.
Sterilization is used for decontamination purposes when there's a need to eliminate all forms of microbial life, including bacteria, viruses, fungi, and spores. This method is crucial in settings such as hospitals, laboratories, and food processing facilities, where ensuring complete sterility is essential to prevent infections and contamination. Common sterilization techniques include autoclaving, dry heat, and chemical sterilants, depending on the materials being treated. It is typically employed for surgical instruments, laboratory equipment, and other items that require a high level of hygiene.
Disinfection and sterilization are both decontamination processes. Disinfection is the process of eliminating or reducing harmful microorganisms from inanimate objects and surfaces. Sterilization is the process of killing all microorganisms.

Type of decontamination that is carried out by a unit to reduce contamination equal to natural background or to the lowest level possible.
Before sterilization, the sterility level is checked by performing biological and chemical indicators tests to ensure that the materials are free from microbial contamination. After sterilization, the sterility level is checked by incubating the sterilized materials in a sterile culture medium and observing for any microbial growth. Additionally, physical monitoring such as checking for any breach in packaging integrity can also indicate the sterility level post-sterilization.
Low risk may involve using general workers trained in decontamination procedures, while moderate risk may require specialized decontamination teams equipped with proper gear. High-risk decontamination would typically involve hazmat or emergency response teams with extensive training and equipment. The level of risk will determine the expertise, training, and resources needed for effective decontamination.
