During pressure testing, which part of the tank should you maintain distance from?

During pressure testing of underground storage tanks, it is important to maintain distance from the end manways fittings. This area is crucial because it is where the tank is filled, emptied, and accessed for inspection and maintenance. If there are any failures or leaks during the pressure testing process, these fittings can be especially vulnerable and may pose a risk due to the sudden release of pressure or hazardous materials.

End manways fittings are critical structural points that can experience stress during testing. Standing too close could increase the risk of injury should an unforeseen failure occur. Safety protocols often emphasize keeping a safe distance from any fittings or access points to minimize exposure to potential hazards during pressure testing operations.

While concerns for safety and structural integrity apply to various parts of the tank, surrounding areas such as the tank body, top of the tank, and access door areas typically do not pose the same level of specific risk as the end manways fittings in the context of pressure testing. Therefore, the need for caution is specifically heightened around the end manways.
