How far must exhaust from mechanical ventilation systems serving machinery rooms be discharged from property lines or openings into buildings?

The correct distance for discharging exhaust from mechanical ventilation systems serving machinery rooms is 20 feet from property lines or openings into buildings. This requirement is established to ensure safety and prevent the infiltration of exhaust gases or pollutants into occupied spaces or neighboring properties.

Maintaining this distance minimizes the risks associated with exhaust emissions, including exposure to harmful substances and unpleasant odors that may arise from machinery operations. Proper separation also contributes to improved air quality in surrounding areas and buildings by reducing the likelihood of exhaust re-entering through windows, doors, or other openings.

By adhering to this regulation, facilities ensure compliance with safety standards and best practices for environmental health.
