Describe how and when disinfectant agents are used, Calculate the following and povide the answer rounded off to the correct accuracy Disinfectants are usually used in the hospitals, kitchens, bathrooms, etc to kill infectious microbes. One of the most cost-effective disinfectants used is chlorine bleach (a 5% solution of sodium hypochlorite), which is effective against most common pathogens, including difficult organisms found in a healthcare setting, such as antibiotic-resistant strains of staphylococcus, fungi, and hepatitis B and C. Disinfection does not necessarily kill all microorganisms, especially resistant bacterial spores; it is less effective than sterilisation. <>/ExtGState<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 594.96 842.04] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>>

Before preparing or eating food it is important to always wash your hands with soap and water for at least 40-60 seconds. Factors that affect the efficacy of both disinfection and sterilization include prior cleaning of the object; organic and inorganic load present; type and level of microbial contamination; concentration of and exposure time to the germicide; physical nature of the object (e.g., crevices, hinges, and lumens); presence of biofilms; temperature and pH of the disinfection process; and in some cases, relative humidity of the sterilization process (e.g., ethylene oxide). Sterilizationdescribes a process that destroys or eliminates all forms of microbial life and is carried out in health-care facilities by physical or chemical methods. Gelling granules should be used especially where there are copious amounts of fluids involved. #wWs~X%Q+};/[0TD OTdA S!$k

Disinfection differs to sterilisation whereby the object is free of all viable microorganisms. Sterilization is intended to convey an absolute meaning; unfortunately, however, some health professionals and the technical and commercial literature refer to disinfection as sterilization and items as partially sterile. When chemicals are used to destroy all forms of microbiologic life, they can be called chemical sterilants. The process of laundering contaminated linen (including clothing) requires treatment that is effectively a wash-based disinfection process, and is required to avoid cross infection from re-used items.
