What is the minimum distance that outdoor air intakes must be from waste air discharges?

The correct answer is based on regulations that aim to promote air quality and prevent the contamination of indoor environments within nursing homes. Specifically, outdoor air intakes must be adequately distanced from waste air discharges to reduce the risk of harmful pollutants, odors, and particulate matter from adversely affecting the air that is introduced into the facility.

A distance of 25 feet is generally considered sufficient to allow for natural dispersion and dilution of exhaust contaminants, thereby safeguarding the health and comfort of residents and staff. This minimum distance helps to minimize the chances that harmful airborne substances emanating from waste air discharges will re-enter the building through air intakes, ensuring a safer, healthier living environment.

Other distance options, while they may seem reasonable, do not align with established health regulations that prioritize indoor air quality, underlining the importance of adhering to this specific measurement. By following this guideline, facilities can maintain compliance with health regulations, promote better air quality, and support the well-being of all individuals within the nursing home.
