Cause of the fire has been preliminarily determined as the bedroom, use the "heater" and will lead to electrical failure caused by the surrounding combustibles. As the culprit in the incident, "heater" is not only a college clamp down on, crush objects, has entered parts of the blacklist, strictly prohibit the marketing. "Heater" is a use of nickel-iron alloy heating wire heating, acting on the fluid of small fast electric heater, although the Business School in Shanghai incident into a major disaster, but the heating speed, low price, in universities, as well as some of the mobile site has been very market place. College near Ms Cheng told reporters: "heater" has been with her throughout the college years, the price is very cheap, stall, bought small commodity wholesale market also 35 dollars. Special ring when the boil water, the total people nervous, afraid suddenly exploded. Product life is not long, often baffling and it broke. In Miss Cheng's memories, since the use of adjacent bedroom has "heater" nearly causing a fire still haunt the memory of, after graduating from college, she never used "heater." At a Beijing university graduate student Xiao Zhou on the "heater" enthusiastic. Electric kettle was confiscated because the big power, he can only go to the supermarket to buy the school a "heater", "price as long as 10 yuan, even then will not feel distressed by check." Xiao Zhou told reporters: "Ten boys bedroom There 89 are in use, normal use should not go wrong. "heard" heater "for the fire incident was blocked universities, he felt was unworthy, can not understand. Although different views on the reporter found that most students do not agree with the school in the block "heater." In fact, even block calls everywhere, "heater" has not really disappeared around in college. Reporters recently from the Beijing Foreign Economic and Trade University near Shuntian supermarket that "heater" is still normal sale price of 18 yuan, packaging rough, fuzzy identification, some products are not even the packaging, the quality good or bad no way judge. Then, Shuntian supermarket next to the counter hardware products, the sales staff has come up with a different color of the "heater" any press selection, several products are not only different packaging, different materials and prices from 8 yuan to 18 yuan per yuan of which 10 are simple plastic packaging products, some products have significant rust heating rods. Sales staff said that all products are safe and reliable, but the two 18 per product with best quality. One well-known brand products (indicated on the package is well-known trademarks) and the other installed automatic temperature control settings. When asked what the role of automatic temperature control, sales personnel and knowledge. In addition, the reporter noticed a detail sales force recommended to reporters two best-selling "heater", which is a white ceramic heating rods, the product packaging specifically pointed out that the color enamel rods at a high temperature heating easy to precipitate chromium oxide or cobalt oxide, adverse health. The sales staff repeatedly emphasized the "safe and reliable, not easy to fade" and another "heater" is the color heating rods, and obviously self-contradictory. It is understood that the sales of the "heater" is divided into three categories: only after the heating function, power, water, alarm whistle after opening, the case of dry automatic power off of. Most of them see as reporter, only a plastic bag, does not indicate the manufacturer or safety alerts. The event of failure or dry, the metal outer tube may be quickly seared, then cause an explosion or leakage. National quality inspection center of home appliances small home appliances division deputy director, test engineers, ZHANG Zhao-ming told reporters that dry is the "heater" the most dangerous working conditions, regular "heater" should be very disconnected with all non-self-reset device or anti-dry equipment, better quality products that are equipped with temperature control, once the temperature is too high will automatically stop working.
