What is the maximum allowed percent capacity for transporting storage tanks?

The maximum allowed percent capacity for transporting storage tanks is typically set to ensure safety during transport and to minimize the risk of spills or leaks. In the context of transporting storage tanks, the 5% capacity allowance serves several important safety and regulatory purposes. It helps to provide adequate space for the liquid to expand during temperature fluctuations, which is crucial to prevent overfilling and potential breaches in the tank.

Additionally, this smaller percentage contributes to reducing the risk of accidents during transportation, as it limits the movement of liquid within the tank, which can affect the vehicle's stability. It also aligns with regulatory standards aimed at preserving environmental safety and public health. Thus, the choice of 5% is established as a precautionary measure to uphold the necessary safety guidelines in moving hazardous materials.
