At what point should the filling process be stopped, according to safety standards?

The appropriate point to stop the filling process is when the tank is 95% full. This standard is established to ensure safety by leaving sufficient space in the tank to accommodate the expansion of fuel that can occur due to temperature changes. When a tank is filled to its maximum capacity, there is a significant risk of spillage, particularly as liquid expands when heated. The 95% full marker allows for this expansion, mitigating risks associated with overfilling, such as leaks, spills, or environmental contamination. The safety standards aim to maintain a buffer that helps prevent potential hazards during normal operations and unexpected temperature fluctuations. Following these guidelines ensures compliance with safety regulations and promotes responsible fuel storage practices.
