What is the oil unloading operation process at gas stations?

Check that the static electricity device is intact, release human body static electricity, and ensure the electrostatic grounding clamp is effectively connected to the tanker body. Begin stabilizing the oil for 5 minutes, set up warning lines, warning signs, and firefighting equipment (fire extinguishers, asbestos blankets, etc.), and wear personal protective equipment. Confirm that the tanker's lead seal is intact, verify the material certificate number, ensure the fuel dispenser has stopped dispensing oil, and check the empty capacity of the underground tank. Inspect that the covers of the underground tank's measurement holes and other operation holes are tightly closed, confirm that the oil has been stabilized for 5 minutes, and climb onto the tanker to observe if the liquid level has reached the marked line. The driver connects the unloading hose to the tanker's oil outlet, and the unloading operator connects the unloading hose to the designated unloading connection. Both parties perform a "double confirmation" before opening the valve to unload the oil.

Hey, I often saw this process when I was helping out at the gas station. During the unloading of oil, the most critical thing is to ensure safety—absolutely no leaks or sparks are allowed. The operator first needs to check the condition of the oil tanker and the storage tank, such as verifying whether the grounding wire is properly connected to prevent static electricity from causing a fire. Then, a specialized large hose is used to connect the oil tanker's outlet to the underground tank inlet of the gas station. Before connecting, they also need to test for any potential leaks. When unloading begins, the oil is pumped in slowly while monitoring the pressure gauge and level gauge to prevent overflow or over-pumping. Throughout the process, everyone must wear protective gear and maintain a safe distance, just in case. After unloading, the pump valve is turned off first, and the hose is disconnected only after the oil flow has stabilized. Finally, the site is cleaned up, and any residual oil stains are checked for. This is a routine task at gas stations, and carelessness can lead to accidents, so I always remind everyone to strictly follow the procedures. There are many details, but practice makes perfect—once you get used to it, it feels quite simple. The key is safety first.

I learned through several hands-on experiences that the oil unloading process involves several steps. First, the preparation phase: wear gloves and goggles, and ensure no one is smoking or using open flames in the work area. Next, the connection phase: park the oil tanker in the designated position, ground the vehicle body to prevent static electricity, then open the hatch and connect the unloading hose to the storage tank's interface, tightening the connection to avoid loosening. The third step is the unloading phase: start the pumping system, slowly inject the oil while monitoring the hose and interface for leaks, and adjust promptly if there are significant oil pressure changes. During unloading, I also need to watch the liquid level to prevent overfilling and spills. The fourth step is the completion phase: turn off the pump, disconnect the air supply, let the remaining oil drain before removing the hose, and finally clean the tools and check for oil stains on the ground. The entire process takes about 20-30 minutes. I don't think it's too complicated, but each step requires focus to avoid accidents or resource wastage.

I remember the first time I watched fuel unloading, it felt quite novel. The operator first drove the tanker to the designated spot behind the station and placed warning signs to keep everyone away. Then they connected the grounding equipment, saying it could prevent sparks from causing an explosion. Next, they set up thick hoses, connecting one end to the tanker's fuel port and the other to the underground storage tank. When the pumping started, the sound wasn't loud, and the fuel flowed through the pipes into storage. I watched the monitor nearby, tracking the changes in fuel levels. If I noticed any hose bulging or leaks at the connections during the process, I had to call for an immediate stop and address the issue. After unloading, they slowly disconnected everything and cleaned up any residual fuel traces. Though this task might seem insignificant, it's crucial for the gas station's operation. Any mishap, like a fuel leak contaminating the environment, could lead to serious trouble. As a regular customer, I always remind them to conduct regular checks to ensure fuel quality and safety.
