Since you didn't provide a list of options, I can't point to the specific "following" item you're looking for. However, in common medical and safety tests (like CNA or dental exams), disinfection refers to the use of chemicals or physical processes to kill most germs on inanimate objects and surfaces.
Chemical disinfectants from the Guideline for Disinfection and Sterilization in Healthcare Facilities (2008).
An example of disinfection is cleaning a shower chair with a chemical cleanser.
Iodophor and synthetic phenol compounds are examples of intermediate-level disinfectants that are appropriate for use on clinical contact surfaces in the dental operatory.
Disinfection eliminates or reduces harmful microorganisms (like bacteria and viruses) on nonliving surfaces and objects. Common examples include using household bleach (sodium hypochlorite) on bathroom tiles, 70% isopropyl alcohol for medical thermometers, and quaternary ammonium compounds (quats) on gym equipment.
The two primary methods of disinfection are thermal (heat) disinfection and chemical disinfection.
Chlorine is the universal disinfectant, active against all microorganisms. It is generally served in the form of sodium hypochlorite, with different concentrations of free chlorine. As a general disinfectant for all types of laboratory work, a concentration of 1 g/l (1000 ppm) of free chlorine is used.
The level of disinfection or sterilization depends on the intended use of the object: critical (items that contact sterile tissue, such as surgical instrument), semicritical (items that contact mucous membranes, such as endoscopes), and noncritical (items that contact only intact skin, such as stethoscopes) require ...
After a patient examination, you must disinfect all surfaces and equipment that were potentially contaminated. This stops the spread of pathogens and ensures a safe environment for the next patient.
OSHA recommends using an EPA-registered tuberculocidal disinfectant or a freshly prepared 1:10 dilution of household bleach (5.25% sodium hypochlorite) for decontaminating blood spills. The bleach solution should be applied to the area for at least 10 minutes to ensure proper disinfection.
Disinfection is most accurately defined as the process of eliminating or killing pathogenic microorganisms (germs) on inanimate objects and surfaces. It destroys the vegetative forms of pathogens so they no longer pose a threat of disease, but it does not necessarily kill all microbial life (like bacterial spores).
Physical disinfection methods: procedures and applications
UV-C-Light uses shortwave radiation to destroy microorganisms and is increasingly used for air and surface disinfection. Filtration mechanically removes microorganisms, for example in water systems, and is widely used in the food industry.
It is important to note that, for effective disinfection, chemicals must be used at the correct concentration. What chemicals are commonly used? Three main types include; Isopropyl (Rubbing) Alcohol, Chlorine-containing products such as bleach and quats, and Hydrogen Peroxide.
Types of Disinfectants Used in Hospitals
The most common disinfectant is household bleach (sodium hypochlorite). It is universally used because it is inexpensive, fast-acting, and highly effective against a broad spectrum of bacteria, viruses, and fungi.
A disinfectant is a chemical agent or substance applied to non-living surfaces (like countertops, floors, or medical instruments) to destroy or inactivate harmful microorganisms such as bacteria, viruses, and fungi.
Housekeeping surfaces should be cleaned with soap and water or a detergent/disinfectant.
In general: Sterility is required for critical items that will touch sterile tissues (e.g., surgical instruments) • Intermediate to high-level disinfection is required for items that will touch non-intact skin or mucous membranes (e.g., respiratory equipment, ear syringe equipment, vaginal specula, thermometers, etc.)
What are the two methods of disinfection?
Effective cleaning and disinfection require a systematic, five-stage process to remove debris, eliminate germs, and prevent cross-contamination.
Wash bedding and towels in hot water. Sanitize and disinfect frequently touched surfaces, like light switches, doorknobs, phones, remotes, faucets and toilet handles. Clean any drinking glasses, water bottles or utensils used while sick.
An example of disinfection is cleaning a shower chair with a chemical cleanser.
54 defines several grades of disinfectant as will be used below.
Disinfection is the removal, deactivation, or killing of pathogenic organisms either by physical or chemical methods. The three most common ways to disinfect wastewater are chlorination, ozonation, and ultraviolet.
