Safety technology of the hottest gas station

Gas station safety technology

(I) refueling site and fuel dispenser

refueling site and fuel dispenser are the parts that directly refuel users, and also the main places that directly emit diffuse oil and gas. Don't you know? Leakage, oil leakage of automobile fuel tank, leakage of fuel dispenser, etc. will form explosive gas cooling in the gas station area. Usually, water-cooled mixture is used. Static electricity, electrical sparks, open fire and filling oil in plastic barrels may cause fire and explosion accidents in gas stations

(II) management room

the management room is generally isolated from the refueling site and refueling machine, but oil and gas are still very easy to escape into the management room, indoor open fire, smoking of personnel on duty, etc., which may cause fire and explosion accidents

(III) oil tank and pipeline

among all kinds of accidents in gas stations, oil tank and pipeline accidents account for a large proportion. When the oil tank leaks or discharges oil to the oil tank, the concentration of explosive gas mixture in the area will exceed the lower explosion limit. At this time, in case of open fire, electrostatic spark or lightning stroke, fire and explosion accidents may be caused

(IV) oil loading and unloading process

the oil loading and unloading process is not carried out in accordance with the requirements of rules and regulations, such as unloading the oil without eliminating the static electricity of the oil delivery vehicle, refuelling the vehicle without flameout, unloading the oil into the oil tank in thunderstorm days, too fast unloading speed, incorrect refueling operation, lax management of open flames, etc., which will cause fires and personal injury accidents

On July 23, 2001, a gas station in a city in Henan Province suddenly exploded, causing 4 deaths and 12 injuries, and a direct economic loss of 160000 yuan. The cause of the accident was the serious oil leakage of the tanker, which caused a large amount of oil and gas to diffuse in the basement, forming an explosive gas mixture and being ignited by a non explosion-proof electric light switch. After the investigation, experts confirmed that cracks and oil leakage occurred in the weld of the vertical pipe under the fuel dispenser at the southeast side of the gas station. The design of the gas station is unreasonable, the basement is set under the fuel dispenser, and the operators operate in violation of rules and regulations, which eventually leads to accidents

on November 29, 2001, a gas station on a national highway in Gansu Province suddenly exploded violently, and the concrete pouring ground within hundreds of square meters was lifted up. The explosion blast completely destroyed the glass of nearby buildings and buildings. There were 17 casualties in the accident, one of which was not only an indispensable basic production link of a large number of industrial and agricultural products, but also people died. It is estimated that the accident was caused by the explosive gas mixture formed by the oil pipe leakage being ignited by static electricity or open fire

on October 13, 2001, on the road from a city in Hebei Province to a city, a car tanker loaded with gasoline caught fire. After three loud noises, the oil tank mouth, cab, chassis and tires of the car were all on fire. The oil tank containing 20t gasoline was in danger of explosion at any time. Fortunately, firefighters struggled to put it out. The fire seriously injured two drivers. The direct cause of the accident was the illegal transportation of gasoline by a tank car designed to load diesel

the gas station accident case shows that the design does not meet the specification requirements, leaving hidden dangers of accidents, and the construction quality does not meet the requirements, leaving hidden dangers of accidents, as well as illegal command, illegal use of fire, and illegal operation. What is the development prospect of "king of new materials" graphene in China? Is the main cause of the accident
