What are the contents of daily safety management of gas filling stations?

it is not enough to do a good job in the safety management of gas filling stations to ensure the normal operation of gas filling stations. It is also necessary to formulate a set of feasible safety management methods and operating procedures according to the characteristics of gas filling stations and the relevant regulations on fire control in petrochemical industry, and implement them strictly when they arrive at their posts, so as to effectively prevent, control and eliminate fire and explosion accidents. Safety management measures of filling stations have the following characteristics besides safety management measures of filling stations.

1. Establish a system of fire prevention, explosion prevention and leakage prevention

(1) Establish a fire safety responsibility system, implement special personnel management, and put the safety management of fire prevention, explosion prevention and leakage prevention in the first place in 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 of 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

As the saying goes, "fire and water are ruthless", and 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. When operating and maintaining equipment, explosion-proof tools should be used.

(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.

(4) Before refueling, the operator shall conduct safety inspection on the gas cylinder instrument and valve pipeline 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) During operation, the aerated rubber (soft) pipe shall not be handed over or bypassed by other equipment.

(7) When the internal pressure of 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, pay attention to monitoring whether the liquid level or pressure of the metering instrument of the refueling machine and the gas cylinder of the vehicle are normal.

(9) During the filling period, operators are not allowed to leave the site, and it is forbidden to let non-operators operate on their behalf, and it is forbidden for non-operators to take the initiative to fill themselves.

(1) In case of emergency (such as vehicle or equipment leakage) during refueling, the operation should be stopped immediately. (11) After gas filling, close the gas filling gun, vehicle gas cylinder valve and gas filling pipe valve, unload the gas filling gun, cover the gas filling port protection cover, verify the gas filling quantity, and confirm that there is no air leakage before allowing the driver to start the vehicle. (12) During the gas unloading and filling operation, the safety officer shall regularly inspect the operation parameters of the gas storage tank, and stop the operation of the submersible pump and the filling operation when the liquid level of the gas storage tank is lower than 2%.

(13) It is forbidden to fill the automobile gas cylinders without the inspection certificate of the technical supervision department at the filling station; It is strictly forbidden to refuel any gas devices and gas cylinders other than automobile gas cylinders. V. Rules for Safe Operation of Aeration

(1) Aerators must have knowledge of LPG (or CNG) and fire fighting, and should hold relevant certificates. (2) After the gas vehicle is positioned, the gas attendant checks whether the engine is turned off and whether the hand brake is put on. (3) For refitted vehicles, before refueling, the gas filler should ask the driver to open the rear cover of the vehicle and check whether the container is within the service life and has the specified label. Check the liquid level gauge, valves and piping of the container for gas leakage or other abnormal conditions by looking, listening and smelling. For non-modified vehicles, drivers should be required to cooperate with the above work.
