Fire hazard of gas station:
1. Gas stations mainly deal in gasoline and diesel. The flash point of gasoline is generally between-50 and-30, the flash point of diesel is generally between 60 and120, the explosion limit of gasoline is between 1.5-6.48% by volume, and the explosion limit of diesel is between 1.5-6.5% by volume, which has great fire hazards. At room temperature, gasoline can volatilize a large amount of steam, which is easy to burn and explode in case of open flame or electric spark.
Second, there are many gas stations, long lines and wide areas, and the management components are complex, both collective and individual, which is difficult to manage. The quality of fire safety of gas station personnel is poor, the safety system and fire control organization are not implemented, and efficiency is emphasized, but safety is ignored. Individual gas stations operate with light oil, which increases the fire risk of gas stations.
Third, with the increase of operation time, the fire-fighting equipment in gas stations lacks maintenance, the electrical wiring is aging, the electrostatic discharge is poor, the equipment is prone to leakage, and the unsafe factors are increasing. If it is not eliminated in time, it is prone to fire.
Fourth, there are many foreign workers in the gas station, individual drivers and passengers have poor awareness of fire prevention, and there is smoking in the station, which is more likely to cause fires.
Main measures of fire safety management in gas stations;
First, from the address selection, strictly control the site selection: the oil station has great fire risk and is prone to combustion and explosion. So site selection is a key step. The address of the gas station shall meet the requirements of urban planning and fire safety, and it shall be not less than 50m away from important public buildings, 30m away from open flames and fire-prone places, 25m away from the first-class station, 25m away from the second-class station and 17.5m away from the third-class station. It should also avoid crowded places, and overhead communication lines and power lines should not cross gas stations.
Second, strict inspection and acceptance. Doing a good job of examination and acceptance is the key to prevent gas stations from leaving fire hazards; Codes and standards should be strictly implemented during the audit, and the main audit contents include: surrounding environment, general layout, fire prevention spacing, electrical installation, electrostatic grounding, installation of oil tanks and pipelines, fire control facilities, etc. , pay special attention to the following points:
First of all, the oil tank directly buried in the ground should be well protected against corrosion and ground sealing. Safety measures should be taken to prevent the oil tank from floating or sinking. Clean sand or fine soil with a thickness of not less than 0.3m should be backfilled around the oil tank, and a fire dike should be set up for the above-ground oil tank. The pipeline should pass through the fire dike and must be tightly packed with incombustible materials. Second, the power lines in the station are directly buried by cables, and the parts crossing traffic roads are protected by steel pipes. Cables shall not be laid in the same ditch as the pipelines in the oil station. Oil pipelines and cable trenches must be filled with sand. 3. The elevation of the gas station building, refueling island and terrace should be 0.2m higher than the oilfield terrace, the width of the refueling island should not be less than 1.2m, and the distance between the pillar of the refueling island and the end of the refueling island should not be less than 0.6m；; 4. The oil inlet pipe of the directly buried underground oil tank should extend downward to the tank 0.2m away from the bottom of the tank. The nominal diameter of the vent pipe should not be less than 50mm, and it should not be less than 4mm from the ground, and a flame arrester should be installed.
Third, do a good job in pre-opening training and establish and improve rules and regulations. According to the "Shandong Province Fire Management Measures", flammable, explosive and special post personnel must be trained and obtain a fire safety certificate before taking up their posts. Therefore, it is very necessary to do a good job of training before opening. Through training, all personnel can master the flash point, ignition point, explosion limit, fire danger, matters needing attention in oil loading, unloading and refueling, the use of fire-fighting equipment and common sense of fire prevention.
Fourth, strengthen safety management, carry out regular fire inspection, and eliminate fire hazards in time. Gas station leaders should establish the idea of safety first, educate employees to strictly abide by the operating rules, especially the fire safety in the process of loading, unloading and refueling, regularly check whether the electrical equipment, electrical wiring, static elimination and fire-fighting facilities meet the requirements, and regularly report the fire safety situation of gas stations to the fire department. The fire department should establish archives and file the report, so as to know the safety situation of the gas station in time.
Five, the special treatment of gas stations, regular review, combined with flammable and explosive special treatment activities, the gas station can not meet the fire safety requirements for special treatment, rectification within a time limit. Those who fail to pass the rectification and have serious problems are not allowed to operate, and the situation of the oil station is reviewed and accepted once a year to see whether the electrical equipment, lines, fire-fighting equipment and electrostatic discharge meet the requirements, whether the fire safety system and fire-fighting organization are established and improved, and whether the oil tanks and pipelines are leaking. Through re-inspection and acceptance, the existing problems are eliminated in time to ensure that the oil station meets the fire safety requirements and prevent the oil station from burning.
