What is the minimum height for exit terminals of mechanical draft systems located adjacent to public walkways?

The minimum height for exit terminals of mechanical draft systems adjacent to public walkways is established to ensure safety and prevent any potential hazards to pedestrians. The requirement for a height of 7 feet helps to avoid accidental contact with the exhaust from these systems. By positioning the exit terminals at this height, it minimizes the risk of individuals walking beneath the draft system being exposed to harmful fumes or other dangerous materials that might be expelled.

This particular height standard also takes into account the typical stature of individuals and allows enough clearance to ensure that exhaust does not interfere with everyday activities near public pathways. It ensures compliance with safety regulations and best practices designed to protect public health in areas where people commonly pass by.
