What must be done with linens and towels after they have been used?

After linens and towels have been used, they must be deposited in a closed receptacle and not used again until sanitized. This practice is essential for maintaining hygiene and preventing the spread of infections or bacteria. By placing used linens and towels in a closed receptacle, it minimizes contamination and prepares them for proper washing and sanitizing.

Sanitization is crucial because any contaminants or pathogens present on the linens and towels can pose health risks if they are reused without thorough cleaning. This process ensures that all items are hygienically safe for subsequent use, adhering to health and safety regulations within medical and hospitality settings.

The other options suggest practices that could lead to inadequate sanitation. Reusing linens immediately or washing them without proper sanitization does not ensure that any potentially harmful microorganisms are eliminated. Leaving linens out for drying without washing them first also fails to address cleanliness concerns. Thus, option B is the only answer that aligns with best practices for sanitation and hygiene.
