What sign must be displayed at all hand washing sinks?

The answer "Wash Hands" is the appropriate choice because it is a clear and direct reminder to employees to maintain hygiene by washing their hands. Such signage plays a crucial role in food safety, as proper handwashing is essential to prevent the spread of foodborne illnesses.

Having effective signage at handwashing sinks ensures that employees are consistently reminded of the importance of this practice, especially in food handling environments where cleanliness is critical. Clearly labeled signs can help reinforce the habit of washing hands at key moments, such as before food preparation, after handling raw ingredients, or after using the restroom.

While similar wording in other choices suggests handwashing as well, “Wash Hands” is the more standard and straightforward phrase that aligns with health and safety regulations, ensuring that it is instantly recognizable and understood by all employees.
