What action should a retail project take to minimize occupant exposure to environmental tobacco smoke?

Minimizing occupant exposure to environmental tobacco smoke is essential for maintaining a healthy and safe indoor environment. Implementing a no-smoking policy is a proactive step in this regard. By posting signage indicating the no-smoking policy within 10 feet of all building entrances, the project effectively establishes clear and visible communication about the smoking restrictions. This helps to create a buffer zone that reduces the likelihood of smoke entering the building through doors and windows directly exposed to outside air.

This approach encourages individuals to adhere to the smoking policy before they approach the building, thereby protecting occupants from secondhand smoke. Signage is an important tool in fostering awareness and compliance among both employees and visitors, making it a practical action to decrease smoke exposure.

While the other options may contribute to a broader strategy for managing smoking-related issues—such as fostering communication about smoking (employee meetings), improving indoor air quality (air purifiers), or designating specific areas for smoking (designated smoking areas)—they do not directly control exposure in the same effective manner that well-placed signage does. The signage serves as an immediate visual reminder and promotes adherence to the no-smoking policy at critical entry points to the building.
