What sign must be displayed throughout food service facilities to promote a smoke-free environment?

The sign that must be displayed throughout food service facilities to promote a smoke-free environment is the "No Smoking Sign." This signage is a direct and clear message to patrons and employees that smoking is not permitted within the premises. It helps create a healthier atmosphere by reducing exposure to secondhand smoke, which is a significant health risk in enclosed spaces.

Displaying a "No Smoking Sign" aligns with the regulations and laws regarding smoking in public places, especially those that serve food. These signs are often legally required in various jurisdictions, including New York City, to ensure compliance with public health guidelines. The clear and understandable nature of the sign allows for immediate recognition and understanding of the policy, which is crucial in a food service environment where health and safety are priorities.

While other options may reference policies related to smoking or tobacco use, the "No Smoking Sign" specifically addresses the immediate need for a smoke-free space, making it the most appropriate choice for food service facilities.
