How to do a good job of safety management of gas station?

Decision to do a good job of safety management of gas station, to ensure the normal conduct of business activity, only the configuration of the device is not enough, must also be based on the characteristics of LPG stations, combined with the relevant provisions of the petrochemical industry of fire management, formulate a set of practical safety measures for the management and each work procedure, and carry out to work, to people, strictly enforced, to effectively prevent, control and eliminate the fire explosion accidents.The safety management measures of filling stations have the following characteristics besides the safety management measures of filling stations.

1, the establishment of fire prevention, explosion prevention and leakage prevention system

(1) Establish fire safety responsibility system, implement dedicated management, and put fire prevention, explosion prevention and leakage prevention safety management in the first place in all work.In the process of operation of the filling station can not have a trace of paralysis thought and fluke psychology.

(2) According to the actual situation of the filling station, the working system and working procedures of each post suitable for the filling station should be formulated scientifically and reasonably.

(3) Strengthen the safety education of employees, including the study of gas and fuel knowledge, establish safety concepts and enhance safety awareness.

2. Strengthen the management system of open fire and prevent fire from entering

As the saying goes, "fire and water are merciless", the "fire" of liquefied petroleum gas (LPG) station and natural gas (CNG) station is more merciless, and the loss and harm caused by fire explosion is greater than that of other industries.General material fire, spread and expand the speed is relatively slow, in the early stage of occurrence, the scope is small, more easy to extinguish.Liquefied petroleum gas and natural gas fire spread and spread very fast, its flame speed up to 2000m/s.Above, and difficult to extinguish, especially the explosion accident, once happened, will immediately cause major disasters.To strengthen the management of open fire and prevent the entry of fire is a primary measure for the safety management of filling stations. The following points should be done in detail.

4, air operation safety management

(1) During operation, each inflator shall have a staff member, but one person cannot operate two air guns at the same time.

(2) The operator should stand on the side to guide the vehicle into the station. The car should stop at the designated position with obvious marks, and keep a distance of more than 1m from the inflator.

(3) After the car stops, the worker should supervise the driver to pull the handbrake, turn off the engine, take off the key, leave the cab, and turn off the lights at night.

(4) Before gas filling, the worker should check the safety of the vehicle's gas cylinder instrument and valve pipeline to see whether it is within the service life.

(5) The submersible pump can not be started until the valves of the liquid outlet line and the return line are all opened.The regulating valve (or safety return valve) on the bypass line of the submersible pump shall not be closed.

(6) Aerosol (soft) pipes shall not cross or pass other equipment during operation.

5. Safety operation rules for air refueling

(1) The aerator must have LPG (or CNG) knowledge and fire knowledge, and should hold the certificate to work on the post.

(2) After the positioning of the aerated vehicle, the aerator checks whether the engine is flameout and the hand brake is on.

(3) For the modified vehicle, before filling the air, the aerator should ask the driver to open the back cover of the vehicle and check whether the container is in service period and has the specified label.Check whether there is gas leakage or other abnormal conditions in the liquid level gauge, valve and piping of the container by means of seeing, listening and smelling.For non-modified vehicles, the driver should be required to cooperate with the above work.

(4) The air feeder shall connect the air gun with the air inlet of the vehicle after inspection and confirm that it is firm.It is strictly forbidden to cross and wrap the air pipe on other equipment.

(5) The aerator shall observe the flow rate and the scale of the container when filling air. The maximum LPG aeration volume shall not exceed 85% of the container volume of the automobile storage tank or the specified red line;CNG refueling volume shall not exceed 20MPa.

(6) In the aeration operation, the aerator is forbidden to hand over the air gun to the customer for operation, and it is forbidden to operate two air guns by one person, and it is not allowed to leave the vehicle that is aerating for free.

(7) The aerator should supervise the driver not to use the brush to clean the vehicle or open the front cover of the engine to repair the vehicle.

(8) In case of serious gas leakage in the process of filling, the aerator should immediately close the cylinder valve of the vehicle and press the emergency closing button at the same time to control the gas leakage in the minimum range.

(9) After the end of air filling, remove and properly place the air gun.

(10) Air filling must be carried out in separate vehicles, and no yard air filling is allowed between vehicles.The use of mobile phones and other mobile communication devices is prohibited in the gas filling area.
