LPG civil gas filling station unloading matters

Before loading and unloading, the car tanker should stop and turn off the flame, connect the ground wire, firmly connect the pipe interface, and exhaust the air inside. During the loading and unloading operation, the vehicle should be turned off to avoid the electric spark generated by the engine, which will cause man-made disasters, but I also noticed that the LPG trailer in some countries is equipped with an unloading pump, which requires the power of the vehicle to drive, in fact, this is very Unsafe, and at the same time, do not use tools that may produce sparks during operation.. In case of thunderstorms, abnormal hydraulic pressure, nearby fire, and other factors that threaten the safety of loading and unloading, the truck tanker should stop loading and unloading operations. After unloading, the vehicle should be parked in the dedicated car tank garage, and should not be parked in other places.
