Final answer:
Sanitizing chemicals in food establishments should be stored away from food and utensils to prevent contamination. Antiseptics are used on tissues to prevent infection, while the effectiveness of disinfectants has been historically compared to phenol. Safety equipment locations should also be known for emergency situations.
Step-by-step explanation:
Sanitizing chemicals should be stored away from food and utensils in food establishments, which corresponds to the answer choice C. This practice is essential to prevent contamination of food and to ensure the safety and health of both employees and customers. Sanitizing involves the reduction of microbes to safe levels, which can be achieved through various methods including thermal sanitization in commercial dishwashers or chemical sanitization on surfaces in environments like hospital rooms.
Regarding the control of microbial growth, specific substances are used depending on the context: antiseptics are suitable for use on living tissues to prevent infection, while effectiveness of chemical disinfectants is often compared to that of phenol. In any environment, especially a laboratory, knowing the location of safety equipment like fire extinguishers and eyewash stations is crucial for safety.
