Static electricity is a common physical phenomenon, which may be generated when people exercise or take off their clothes. Wearing clothes of different materials will produce different levels of static electricity. According to the measurement, the friction between pure cotton clothes can hardly generate static electricity, but when people put on the inner and outer coats of chemical fiber fabrics or wool fabrics, the static electricity generated is relatively large, reaching several hundred volts or even thousands of volts.

The climate in northern China is dry, especially in winter, when people take off their clothes or touch metal objects, the discharge phenomenon is very common, and the sparks generated are visible to the naked eye; Sometimes, the contact between human bodies will also produce a strong discharge, which far exceeds the energy required to ignite and detonate the oil-gas mixture. If the emission occurs at a gas station, it is likely to ignite fuel vapor.

The case of electrostatic ignition of oil-gas mixture caused by clothing friction did happen in China. In a dry winter in northern China, a driver filled up the gas station, opened the tank cover and lifted his coat to pay. As a result, the static electricity of the chemical fiber jacket and sweater ignited the oil and gas coming out of the oil tank mouth, and the flame escaped from the oil tank mouth. Fortunately, the on-site oiler immediately blocked the tank mouth with a wet cloth, thus avoiding a disaster.

It can be seen that the potential danger caused by static electricity of textiles in gas stations should not be underestimated. As a gas station worker, he has long working hours and a wide range of activities in the station. He should pay more attention to dress safety, avoid wearing chemical fiber clothes, cotton inner and outer coats, strictly abide by safety regulations, and wear anti-static work clothes at work. In addition, when maintaining and repairing the equipment, do not wipe the equipment with chemical fiber fabric to avoid static electricity.

The types of accidents caused by static electricity are: poor electrostatic grounding of tanker, broken electrostatic wire or poor contact between refueling gun and oil machine; Wear and take off chemical fiber clothing at the refueling site; Electrostatic sparks caused by illegal use of plastic barrels for refueling; Wear leather shoes with nails and walk around in the field or collide with iron in the field to produce sparks.

Combat method: stop operation. Immediately spray the fire with the nearest fire extinguisher, or spray them one by one, or cover the ground with asbestos or sand. And call 1 19 to call the police. Pay attention to the evacuation of vehicles and cut off the power supply when fighting.
