Where should vent outlets be located in relation to building openings and air intakes?

• A. Next to grade
• B. Below grade
• C. At or above adjacent roof-lines
• D. Vertical to grade

Answer: (C)

The placement of vent outlets at or above adjacent roof-lines is based on safety and environmental considerations. When vent outlets are properly situated at or above the roof-lines, they effectively prevent the accumulation of potentially hazardous vapors around building openings and air intakes. This is crucial in minimizing the risk of flammable vapors entering the building, which could create dangerous conditions for occupants. In addition to safety, positioning vent outlets in this manner enhances the dispersal of vapors into the atmosphere, allowing them to dissipate more effectively and reducing the chances of adverse impacts on air quality. The vertical alignment helps in ensuring that any released vapors rise naturally, benefitting from the upward air currents and avoiding the disruption caused by lower air pressure areas that might occur if the outlets are positioned at a lower elevation. Overall, locating vent outlets at or above adjacent roof-lines is in compliance with safety codes and best practices that are designed to protect both people and the environment from potential hazards associated with fuel storage and vapors.
