The field of infection prevention describes a hierarchy of removal of microorganisms from surfaces including medical equipment and instruments. Cleaning is the lowest level, accomplishing substantial removal. Disinfection involves the removal of all pathogens other than bacterial spores.
The operations of a sterile services department usually consist of the cleaning, disinfection, and sterilization of reusable medical equipment. Reusable medical equipment, or RME, can consist of any medical equipment from stainless steel surgical instrumentation, to IV pumps and crash carts. RME is separated into three classes: non-critical ...

[12] [11] In semi-critical situations, or situations with contact of mucous membranes or non-intact skin, high-level disinfectants are required. Cleaning and disinfecting devices with high-level disinfectants, rinsing with sterile water, and drying all equipment surfaces to prevent microorganism growth are methods nurses and doctors must follow.
A less specific measurement of effectiveness is the United States Environmental Protection Agency (EPA) classification into either high, intermediate or low levels of disinfection. "High-level disinfection kills all organisms, except high levels of bacterial spores" and is done with a chemical germicide marketed as a sterilant by the U.S. Food ...
Gamma radiation is very penetrating, and is commonly used for sterilization of disposable medical equipment, such as syringes, needles, cannulas and IV sets, and food. It is emitted by a radioisotope , usually cobalt-60 ( 60 Co) or caesium-137 ( 137 Cs), which have photon energies of up to 1.3 and 0.66 MeV , respectively.
Earle Spaulding of Temple University (Philadelphia, Pennsylvania) in a 1939 paper on disinfection of surgical instruments in a chemical solution proposed "a strategy for sterilization or disinfection of inanimate objects and surfaces based on the degree of risk involved in their use". [1]
Universal precautions are an infection control practice. Under universal precautions all patients were considered to be possible carriers of blood-borne pathogens. The guideline recommended wearing gloves when collecting or handling blood and body fluids contaminated with blood, wearing face shields when there was danger of blood splashing on mucous membranes ,and disposing of all needles and ...
