For safe dispersal of fuel vapors, to what height must a storage tank vent pipe extend?

The requirement for a storage tank vent pipe to extend to a certain height is rooted in safety protocols designed to prevent the accumulation of potentially hazardous fuel vapors. Extending the vent pipe to a height of 12 feet is crucial for ensuring that vapors disperse safely into the atmosphere, reducing the risk of ignition and exposure to people in the vicinity.

By having the vent pipe at this height, it helps to ensure that any vapors released from the storage tank will rise sufficiently high above ground level, mitigating the chances of them gathering in low areas where they could pose a fire hazard. This height is established based on regulations and best practices that take into account factors such as local air currents and the physical behavior of vapors, ensuring effective dispersion and minimizing risk.

The choice of 12 feet is based on guidelines that aim to protect both property and personnel from the dangers associated with volatile organic compounds. Thus, ensuring vent pipes are of adequate height is a critical aspect of fuel storage safety.
