What are the fire and explosion protection requirements for the construction and structure of automobile filling stations?

1. establish a system of fire prevention, explosion prevention and leakage prevention (1) establish a responsibility system for fire prevention and safety, implement special personnel management, and put the safety management of fire prevention, explosion prevention and leakage prevention at the top of all work. There should not be a trace of paralysis and luck in the operation of filling stations. (2) According to the actual situation of the gas filling station, scientifically and reasonably formulate the working system and * operating procedures for each post that are suitable for the gas filling station. (3) Strengthen the safety education of employees, including the study of gas fuel knowledge, establish safety concepts and enhance safety awareness. Second, strengthen the open flame management system to prevent the fire from entering the common saying "fire and water are ruthless". The "fire" in LPG stations and natural gas (CNG) stations is even more ruthless, and the losses and harms caused by fire and explosion are greater than those in other industries. General material fire, the speed of spread and expansion is relatively slow, in the early stage of occurrence, the scope is small, and it is easier to put out. The fire of liquefied petroleum gas and natural gas spreads and expands quickly, and its flame speed reaches 2 m/s. Above, and it is difficult to put out, especially the explosion accident, once it happens, it will immediately cause major disasters. Strengthening the management of naked flame and preventing the entry of kindling is a primary measure for the safety management of filling stations, and the following points should be done specifically. (1) Warning signs and signs such as "No Fireworks" should be set up in a conspicuous position at the filling station. * Explosion-proof tools should be used when making and maintaining equipment. (2) The speed of cars entering the station shall not exceed 5 km/h.. Tractors, battery cars, motorcycles and animal drawn vehicles are prohibited from entering the station. Third, the safety management of gas receiving and unloading operations (1) Carefully check the delivery documents, check the name, quantity, quality test and the number of the intake tank, and it is strictly forbidden to discharge the gas with excessive corrosive medium into the tank. (2) Unloading operations shall be carried out in strict accordance with *. (3) the car should be parked and turned off according to the designated position, and the car keys should be handed over to the clerk for temporary storage. (4) When unloading gas, the electrostatic grounding wire must be connected first, and the stop valve (ball valve) on the gas and liquid hoses should be confirmed to be closed, and then the gas unloading pipe should be connected. The unloading equipment of tank car shall be made by the gas supplier. (5) During gas unloading, the operator must monitor the site and check the pressure, temperature and liquid level at any time. The liquid volume of LPG gas storage tank shall not exceed 85% of the volume of gas storage tank. The pressure of CNG storage tank shall not exceed 25MPa. (6)* The operator shall supervise the aspirator driver to leave the aspirator vehicle, but not far from the job site, and shall not clean or repair the vehicle. (7) After the gas unloading, the operator * will remove the gas pipeline and electrostatic grounding wire, and after checking, hand over the car keys to the driver, and then send the car to start and leave the scene. Iv. Safety management of gas filling operation (1) During operation, each gas filling machine should have one operator, but one person can't work with two gas guns at the same time. (2)* The operator should stand on the side to guide the vehicle into the station, and the vehicle should be parked at the designated position with obvious signs, keeping the distance from the dispenser above lm. (3) After the car stops, the operator should supervise the driver to tighten the handbrake, turn off the engine, remove the key and leave the cab. Turn off the lights at night. (4) Before refueling, the operator shall carry out safety inspection on the gas cylinder instruments, valves and pipelines of the vehicle to see whether they are within the service life. (5) The submersible pump can only be started after the valves of the outlet pipeline and the return pipeline are all opened. The regulating valve (or safety return valve) on the bypass pipeline of submersible pump shall not be closed. (6) When working, the aerated rubber (soft) pipe shall not be handed over or bypassed by other equipment. (7) When the internal pressure of 7)LPG gas cylinder is too high to be filled, it should be connected to the gas phase return pipe for pressure relief, and it is not allowed to vent on site; When CNG is emptied, it is forbidden to aim the gun at people. (8) During refueling, attention should be paid to monitoring whether the liquid level or pressure of the metering instrument of the refueling machine and the gas cylinder of the vehicle is normal. (9) During the filling period, the working personnel shall not leave the site, and it is forbidden to let the non-working personnel do it for them, and it is forbidden to take the initiative to fill them themselves. (1) In case of emergency (such as vehicle or equipment leakage) during refueling, the operation shall be stopped immediately. (11) Add
