How should tank vents be handled during installation in areas prone to flooding?

Tank vents should be extended above the flood-stage water level to ensure proper function and avoid the potential for flooding-related issues. When tank vents are positioned below the flood stage, they risk submersion during floods, which can lead to blockages, malfunction, and possible overpressure conditions in the tank.

Extending the vents above flood-stage water levels allows for the necessary ventilation of the tank while preventing contamination and the ingress of floodwaters, which could compromise the integrity of the stored product. This practice also helps to maintain compliance with safety regulations that require adequate ventilation to prevent dangerous vapor accumulation and ensure safe fueling operations.

The consideration of flooding is crucial in installation practices, so ensuring that vents are located high enough effectively mitigates risks associated with flooding in vulnerable areas.
