Disinfection-the elimination of virtually all pathogenic microorganisms on inanimate objects with the exception of large numbers of bacterial endospores, reducing the level of microbial contamination to an acceptably safe level.
Decontamination is any activity that reduces the microbial lode to prevent inadvertent contamination or infection. The appropriateness of a decontaminationprocedure is situational-dependent. For example, surgical instruments must be sterile but this level of microbial killing is unnecessary for environmental surfaces such as floors and walls.
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.
Some steps in the process of decontamination of gasoline include cleaning, disinfection and sterilization. You can learn more about gas decontamination at the Germfree website.
If refering to being clean, sterilization is preventing infection and disinfection is removing an existing contamination.
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.
disinfectant gets most of the viruses and bacteria off of something, while complete sterilization is there is absolutely NOTHING on that object. period. it is generally for surgical use that people sterilize rather than disinfect!
The stages of decontamination typically include three key processes: cleaning, disinfection, and sterilization. Cleaning involves the removal of dirt, debris, and organic material from surfaces. Disinfection follows, using chemical agents to kill or inactivate most pathogens. Finally, sterilization eliminates all forms of microbial life, often through methods like heat, radiation, or chemical treatments.
Sanitization reduces the number of microorganisms to a safe level, disinfection kills most microorganisms but not all, and sterilization kills all microorganisms. Sterilization is the most effective in killing microorganisms, followed by disinfection, and then sanitization.

Sanitation involves cleaning to remove dirt and debris, disinfection kills most but not all microorganisms, and sterilization kills all microorganisms. Sterilization is the most effective in eliminating harmful microorganisms, followed by disinfection, and then sanitation.
Hygiene in this context is similar to sanitary procedures, which means to remove gross contamination and maintain a visually clean surface. Disinfection means to remove gross contamination then apply a chemical agent to significantly reduce the microbiological contamination of a surface. Sterilisation means to completely eliminate all living organisms from a surface.
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.
