Final Answer:
Sanitizing articles before disinfecting them serves the purpose of reducing the microbial load on surfaces, ensuring a more effective disinfection process. Sanitization helps eliminate a significant portion of germs, dirt, and organic matter, creating a cleaner surface for subsequent disinfection to target remaining pathogens more efficiently.
Step-by-step explanation:
Sanitizing and disinfecting are two distinct but complementary processes in maintaining a hygienic environment. Sanitization involves reducing the number of microorganisms on a surface to a safe level, typically by 99.9%. This preliminary step is crucial because disinfectants may be less effective in the presence of dirt, debris, or a high microbial load. The reduction achieved through sanitization enhances the efficacy of the subsequent disinfection process.
To elaborate, consider a surface with 1,000,000 microorganisms. Sanitizing reduces this number to 1,000, leaving only 1% of the initial microbial load. This creates a more favorable condition for disinfectants to act, as they can now target a smaller population, increasing their potency. Disinfectants then proceed to eliminate the remaining 1,000 microorganisms, achieving a higher overall reduction in pathogens on the surface.
In summary, the purpose of sanitizing articles before disinfecting them lies in optimizing the disinfection process. By reducing the microbial load beforehand, sanitization creates a cleaner surface, allowing disinfectants to work more effectively and ensuring a more thorough elimination of harmful microorganisms. This two-step approach is integral in maintaining a sanitized and safe environment.
