What system protects CNG tanks from overpressure in case of fire?

The system designed to protect CNG tanks from overpressure in the event of a fire is the overpressure relief valves. These valves play a critical role in maintaining safety by releasing gas to prevent the tank from bursting due to increased pressure caused by the heat of a fire. While fire suppression systems can help to control and extinguish fires, they do not specifically address the risk of overpressure that may result from elevated temperatures affecting the gas inside the tanks. Emergency release valves and cooling systems are also important for overall safety but serve different functions in the context of tank protection. In summary, the overpressure relief valves are essential for mitigating risks associated with thermal expansion of gases in CNG tanks during a fire situation.
