Shanxi Datong Pharmaceutical Factory is the second largest ephedrine producer in China. The red horse brand ephedrine produced by the factory won the national silver award, which not only sold well in the domestic market, but also sold well in the international market, winning a lot of foreign exchange for the country.
Why is there such a big fire in such a large-scale factory?
After the fire broke out, the direct cause of the fire was the overload and heating of the three-phase waterproof wire of the belt conveyor motor, which led to the insulation burning short circuit at the joint.
It turned out that on this day, the workers in the raw material field of the factory were stacking the medicinal materials purchased from all over the country. Each stack of three Sichuan lumbricus is 70 meters long, 15 meters wide, 15-20 meters high and 8- 12 meters apart. With the continuous rotation of the conveyor belt, packages of herbs are sent to the top of the pile. At 6 o'clock in the afternoon, suddenly, with a bang, a small fire ignited the ephedra nearby. At first, no one paid attention to the small fire, and everyone just fanned it a few times. However, after the sun-dried ephedra meets the fire, it burns quickly, and in a short moment, the fire on the field is out of control. The whole raw material yard formed a sea of fire.
According to the regulations, the motor of the belt conveyor is 20 HP, 14 kW, and the conductor with a cross section of 6 square millimeters should be adopted. However, the factory violated the regulations. When replacing the motor wire, change the cross section of the wire to 1. 5mm without the approval of the relevant departments and regular electrician installation. The short circuit of the wire caused the fire.
When the fire broke out, there were 1 1 people on the field. When the wire starts to catch fire, as long as one person can quickly pull down the switch, take effective fire extinguishing measures or call the police in time, the fire will be avoided. Unfortunately, these people don't know this knowledge. It turns out that these people are all contracted by farmers in Inner Mongolia, and they are employed by factories. They have received neither fire safety education nor fire training. Therefore, after the fire broke out, they would only use straw hats, straw bags, Gang Qian and other tools, and would not take effective measures or call the police. Prior to this, the public security fire department repeatedly asked the factory to reduce the reserves, keep the fire safety distance, prepare fire water and other requirements, but it never attracted the attention of the factory, let alone take any preventive measures, which eventually led to disaster.
There is an ancient proverb in China, which is called: "An ant hole can break the embankment of a thousand miles; Toe disease can kill several feet. "This shows that hidden dangers, big or small, cannot be underestimated.
