How far away is smoking prohibited from doors, windows, or ventilation systems of any building?

The correct answer is 25 feet. This distance is established to minimize the exposure of non-smokers to secondhand smoke, which can migrate through doors, windows, and ventilation systems. By prohibiting smoking at least 25 feet away from these areas, the policy aims to create a healthier environment for all occupants within the building. This regulation reflects a growing understanding of the health risks associated with secondhand smoke and aims to provide a safer space, particularly in public and shared environments.

The chosen distance of 25 feet is based on research and public health guidelines that take into account how smoke can easily travel and the potential risks associated with close proximity to secondhand smoke sources. Therefore, enforcing this distance helps protect individuals, especially those who may be more vulnerable, such as children, the elderly, or individuals with respiratory conditions.
