Final answer:
The correct temperature for making McD Sanitizer Solution is room temperature, not too hot or too cold, to ensure the proper function of the sanitizer. For use on tissues to prevent infection, antiseptic solutions are appropriate because they are designed for application on living tissues.
Step-by-step explanation:
The temperature of water for making McD Sanitizer Solution should be room temperature. Sanitizer solutions typically require a specific temperature range to ensure the effective concentration of the active ingredients. Using water that is too hot or too cold could either degrade the sanitizer or impede its efficacy.
There is no direct reference provided for the specific use of sanitizer in McDonald's, but general cleaning guidelines tend to recommend room temperature water unless otherwise specified by the manufacturer. Regarding the selection of microbial control for tissues to prevent infection, antiseptic is suitable. Antiseptics are agents that are applied to living tissue/skin to reduce the possibility of infection, sepsis, or putrefaction.
Disinfectants are usually meant for surfaces, not for living tissue, and sterilants are used for complete sterilization of medical instruments and other items. Water alone, without the addition of antimicrobial agents, does not control microbial growth effectively.
