What must be done if running water is temporarily unavailable during hand washing?

Using an antibacterial skin cleanser is the most appropriate response when running water is temporarily unavailable during hand washing. These cleansers are designed to effectively reduce the presence of pathogens on the skin, which is crucial for maintaining proper hygiene, especially in food service and healthcare settings.

When traditional hand washing is not possible, the use of an antibacterial skin cleanser provides an alternative that helps minimize the risk of spreading germs. It is important to ensure that the product being used is specifically formulated for hand sanitation and contains effective antimicrobial agents.

Other options, such as using water from a bottle or a wet paper towel, may not adequately cleanse the hands or eliminate harmful bacteria as efficiently as a designated skin cleanser would. Skipping hand washing entirely compromises hygiene and poses health risks, emphasizing the importance of finding substitute methods, such as using antibacterial cleansers, when running water is not available.
