(1) Prevent personal charges. During the loading and unloading operation, the human body must be in contact with the working object (fueling vehicle) and the working object to generate friction, which is very likely to generate static electricity, and may form an electrostatic discharge. If the flammable and explosive oil vapor is encountered at this time, An explosion will occur. The operator must wear anti-static overalls and anti-static shoes during the operation, the purpose is to ground the human body. In addition, the shoes should be thin nylon socks or other conductive socks. It is strictly forbidden to affix insulation film on the anti-static sole and should be checked regularly.

　　(2) Electrostatic grounding cannot be ignored. From the point of view of the fuel truck, the main generating parts of static electricity are pumps, filters and pipes. The refueling vehicle filling system produces much more static electricity than the ground pipe. For electrostatic hazards, the following measures must be taken:

　　1 Connect the grounding wire before loading the oil, and check its integrity and grounding resistance to meet the anti-static standards.

　　2 When loading oil, the crane pipe must reach the bottom of the tank, the pipe mouth should be kept at about 15cm from the bottom of the tank, and the initial filling speed should be strictly controlled within 1m/s, until the oil outlet is submerged, then gradually increase the flow rate, but The maximum flow rate must not exceed 4.5m/s to prevent static accidents caused by splashing;

　　3 After the oil is loaded, the ground must be disconnected after 5 minutes of oil stabilization. Because the oil is in the tank after the oil is installed, the oil potential is kept for a few minutes.

　　4 Do not relax your vigilance because of good grounding. Electrostatic grounding can only conduct static electricity on "conductors" (metals, human bodies, conductive liquids, etc.) that are closely connected to them, and to isolated conductors and non-conductors (oil, rubber, resin, glass, etc.) that are not connected to them. Static charge is powerless or difficult to guide in a short time; therefore, the operator should also strictly follow the operating procedures and pay attention to the hidden dangers that may occur at any time while electrostatic grounding, and at the same time grasp the emergency response to various emergencies. Measures and rescue measures

　　(3) The accident caused by “conversion of oil” should also be paid enough attention. This kind of accident mainly occurs when the gasoline is filled with gasoline-filled tanks. The flash point of gasoline is lower than that of diesel. If diesel is injected into a tank containing gasoline vapor, the gasoline vapor is reduced by the absorbed diesel oil. With a small pressure, the air is sucked into the tank, and a flammable mixture is formed somewhere between the surface of the liquid and the point of inhalation of the air, and an explosion accident occurs when the static electricity is accumulated and discharged. Therefore, when it is necessary to "convert the oil", the gasoline in the tank must be cleaned first, and the operation must be carried out in strict accordance with the operating procedures.

　　(4) Use equipment that meets technical specifications and safety requirements. The self-control, remote control, measuring instruments, valves and other equipment of the fuel station must be regularly inspected and calibrated, and the relevant management system should be formulated, especially the material of the oiling equipment should not be underestimated. At the same time, the electrostatic grounding device can not make do with it. It must be handled strictly according to the specifications, carefully installed and regularly inspected. For the common use of clips and magnetic joints grounded, should not be pinched or adsorbed on the free part of the fuel truck, even on the surface of the paint. This is extremely detrimental to anti-static, and it is a big hidden danger. Many users buy cars in order to be cheap, but they don't know how to pay for a penny. Inferior equipment can easily cause accidents. For dangerous vehicles such as tankers, more attention should be paid.
