Gasoline tanks are equipped with several safety devices to prevent accidents and ensure the safe storage and use of gasoline. Here are some of the main safety devices:
- Ventilation System: Gasoline evaporates easily, and the ventilation system allows the release of vapor - ized gasoline and air from the tank to prevent the build - up of pressure. This helps to avoid the tank from bursting due to excessive pressure. At the same time, it also prevents the accumulation of flammable gas mixtures in the tank, reducing the risk of explosion.
- Fuel Gauge and Sensor: The fuel gauge and sensor provide information about the fuel level in the tank. This allows the driver to know the remaining fuel quantity, preventing the engine from running out of fuel. More importantly, it helps to avoid over - filling the tank, which can cause fuel spillage and increase the risk of fire.
- Float Valve: The float valve is designed to prevent over - filling. When the fuel level reaches a certain height, the float valve closes, blocking the inlet of the fuel and preventing more fuel from entering the tank. This effectively avoids fuel overflow and the potential hazards associated with it.
- Anti - Slosh Baffles: These are internal structures in the gasoline tank that reduce the movement and sloshing of fuel when the vehicle is in motion. By minimizing the sloshing, they reduce the risk of fuel splashing out of the tank during sudden stops, turns, or collisions, and also help to prevent the build - up of static electricity.
- Protective Shell and Mounting: The gasoline tank is usually made of strong and durable materials, and it has a protective shell to resist impacts and prevent damage. Additionally, the mounting system is designed to securely hold the tank in place, reducing the likelihood of it becoming dislodged in the event of an accident.

Fire - Resistant Coatings or Linings: Some gasoline tanks are equipped with fire - resistant coatings or linings. These can help to slow down the spread of fire in case of an accident or external fire, providing additional time for emergency response and reducing the risk of a full - scale explosion.
