Using too much sanitizing agent can be toxic. • The three factors that must be considered are: 12. There are five key factors involved when cleaning that are equally important: time, temperature, mechanical action, chemical reaction and procedures. LESSON PLAN in TLE GRADE 7 COMMERCIAL COOKING - Copy.docx, K TO 12 COMMERCIAL COOKING LEARNING MODULE.pdf, 325026181-Detailed-Lesson-Plan-in-T-L-E.pdf, Benguet State University • EDUCATION 1234, Philippines Science High School System • RES 123, Culinary Institute of America • BAKING 101. Different factors influence the effectiveness of chemical sanitizers. Study: 62% Hand Sanitizer Gel More Effective than 40% Ethanol Gel 40% ethanol, tap water, and 40% ethanol gel produced no significant reductions of germs and bacteria. This preview shows page 26 - 28 out of 69 pages. Another way to prevent getting this page in the future is to use Privacy Pass. Concentration and time of exposure are among the most critical factors. Several factors can influence the sanitizing potential of chemical agents. All of the following factors influence the effectiveness of chemical sanitizers, except A. concentration. Too much can be toxic. Certain sanitizers are more active against gram positive than gram-negative microorganisms and vice … It is, for example, un necessary and impractical to steri lise bedpans, baths, eating utensils and so on. What are the factors that influence the effectiveness of chemical sanitizers? The three factors that must be considered are: a. Contact of the sanitizer - in order for a chemical to react with microorganisms, it must achieve intimate contact. Top of Page. chemical sanitizers. Generally, the lower the temperature, the longer it takes to disinfect or decontaminate. • Temperature-- Generally chemical sanitizers work best in water that is between 55oF Chlorine is most effective at pH 6-8.5. Generally, the lower the temperature, the longer it takes to disinfect or decontaminate. D. temperature. - 7395704 myleneagojo19 is waiting for your help. Too much can be toxic. Factors that Influence Effectiveness of Sanitizers Contact Time The amount of time a sanitizer must be in contact with the surface being sanitized Temperature Must be the correct temp. B. contact time. Raise your hand if you're lucky enough to own a bottle—or 40—of hand sanitizer. Selectivity of the sanitizer - certain sanitizers are non-selective in their ability to destroy a wide variety of microorganisms while others demonstrate a degree of selectivity. Pathogens which are There is typically a maximum effect, after which changing a factor will have no effect or will slow a reaction. The amount of minerals you find in water. Concentrations too high are considered toxic and poisonous. Hard water and notably the presence of divalent cations (eg, Mg 2+ , Ca 2+ ) may interfere with the activity of some biocides by blocking adsorption sites on the bacterial cell. Concentration: Proper concentration is critical. What factors influence the effectiveness of chemical sanitizers? Safest Ways of Cleaning, Sanitizing & Disinfecting. These biological factors have an influence on the wider ecosystem. The growth opportunities can be attributed to the fact that these sanitizers are 40% more effective against viruses than normal sanitizers. The chemical should possess a broad spectrum of antimicrobial activity at a low concentration. 8-10 Factors influence the effectiveness of chemical sanitizers. Several factors influence the effectiveness of chemical sanitizers. Acids and bases (such as caustic-soda) are great for cleaning and removing trub and dirt but are not very effective at killing bacteria and yeast and therefore should not be used as a sanitizing agent. Concentration -- The presence of too little sanitizer will result in an inadequate reduction of harmful microorganisms. Time. Different factors influence the effectiveness of chemical sanitizers. C. abrasiveness. Different factors influence the effectiveness of chemical sanitizers. 5 Most Effective Sanitizing Chemicals. Concentration. in pH will also affect the disinfectant efficacy.17 2.4 Factors influencing virus susceptibility There are specific unique characteristics of viruses that influence inactivation by disinfection. Time is the duration allotted to a cleaning task. Too much can be toxic. The chart below is a summary of the main factors that influence the reaction rate. The effectiveness of a disinfectant or antiseptic can be determined in a number of ways. • Different factors influence the effectiveness of chemical sanitizers. 16. For example, increasing temperature past a certain point may denature reactants or cause them to undergo a completely different chemical reaction. The three factors that must be considered are: There are three steps needed to effectively clean and sanitize utensils: Utensils such as cutting boards, bowls and knives need to be thoroughly, washed in warm soapy water. Add your answer and earn points. b. 13. Sanitizing: Sanitizing involves the use of chemical agents to reduce the number of microorganisms on a surface to an acceptable level but does not destroy or eliminate all microorganisms. For example, phenol can absorb into rubber, hence reducing its effective aqueous concentration (Allwood, 1978, Russell, 2004). Temperature — generally chemical sanitizers work best at temperatures between 55°F (13°C) and 120°F (49°C). Several physical and chemical factors also influence disinfectant procedures: temperature, pH, relative humidity, and water hardness. The choice of color depends on the following important factors excepta) the patron's requirementsb) the natural hair colorc) the patron's skin colo … rd) the skin texture2. • What is concentration (of sanitizers) measured in? The 40% gel supplemented with ethanol to a final concentration of 62% reduced the mean CFU by 90%, a level of reduction similar to that of the 62% ethanol gel. FACTORS THAT AFFECT THE PERFORMANCE OF SANITIZERS Temperature- The higher the temperature, the greater the Sanitizers also vary in their effectiveness against yeasts, mold, fungi and viruses. There are a number of factors which influence the antimicrobial action of disinfectants and antiseptics, including: 1. Hypochlorites – Probably the most commonly found chemical in sanitizers, hypochlorite and its compounds are highly effective in killing microbes.
