four people were killed in a fire caused by an electric hair dryer in a group rental house
Zhao is from Huai'an, Jiangsu. Previously, she rented a bungalow with her boyfriend in beixiu village, Gulou District, Nanjing. There are other tenants in this folk house. A fire at the beginning of this year made Zhao a suspect in a fire case. The case was heard in Gulou court.
the fire occurred on January 19, 2015. Zhao recalled that at 1:00 a.m. that day, she returned to her residence to wash her hair. After blowing with the hair dryer, she turned off the hair dryer, put it on the bed and went to the yard to wash clothes. Before long, she saw thick smoke in the yard. She ran back to the house and saw that her room was burning. She quickly knocked on the left and right doors to let everyone escape as soon as possible. Watching the tenants running out one after another, she followed the crowd. Then a neighbor called the police.
the open fire was put out around 3:30 a.m. that day. Unfortunately, four people were killed in the fire. Three of the women lived in the same room. They worked in a snack bar. The boss rented it as a dormitory. Another man who died also came to Nanjing to work and lived in a single room.

the prosecution believed that the hair dryer was not turned off, and the party said it was turned off
Zhao said that she had used the hair dryer for a year or two and had never had a problem. She bought the hair dryer from a market without an invoice. As for the specific brand, she said she didn't remember. She also told the judge that she did turn off the hair dryer at that time, but did not unplug the power plug.
the prosecution said in court that according to the identification, the line of the hair dryer was blown twice. According to this, it can be determined that the hair dryer was powered on at that time. The power on state cannot only be connected to the power supply, but also should be in the on state. Zhao is suspected of the crime of fire, and the prosecution recommends a sentencing of 4-6 years
there was a fire in the rental house, which was caused by an old washing machine
according to reports, just six months before the fire, there was a fire in the rental house. It was an old washing machine on fire. However, the fire was quickly put out and caused no serious damage.
the prosecutor said that due to the increase of rooms, water, electricity and lines need to be modified, which has potential safety hazards. In addition, except for the snack bar, which rented four dormitories, other tenants didn't know each other and didn't know each other very well. And the door is relatively simple, there are hidden dangers of public security.
[hair dryer safety investigation]
some hair dryers in small markets do not have overheating protection
8195. "Later, I bought brand hair dryers, which will stop automatically as soon as the temperature is high." Miss Wang said that at first she thought the hair dryer was broken, but later she knew it was an overheating protection function.
so, what about hair dryers in the market? At present, hair dryers in small markets are available from unknown small brands to large brands. The price is basically 40 or 50 yuan, and the most expensive is no more than 100 yuan. Most hair dryers have signs such as 3C and power on their outer packaging.
do these hair dryers have the function of overheating protection? Many stores said that some small brands basically do not have such functions. "Most people don't blow for an hour or so, but only for ten to twenty minutes. Just pay attention." One boss said.
four people were killed in a fire caused by a girl blowing her head. The safety of household appliances is thought-provoking. The safety of household appliances is thought-provoking
the electric hair dryer can ignite the cotton cloth in 8 seconds
in early 2015, the website of Zhejiang Provincial Bureau of Quality Supervision announced the results of special supervision and random inspection on the quality of hair dryer products in Zhejiang Province in 2014. The results showed that the batch failure rate was 52.9%. In March, Jiangsu Provincial Bureau of quality supervision also issued a random inspection report on hair dryer products, with a qualified rate of 79%, and more than 20% of them were unqualified.
in the risk monitoring of the hair dryer, the experimenters found that if there is no overheating protection device, the temperature of the cotton cloth rises rapidly from normal temperature to 200-300 ℃ in just 8 seconds when the hair dryer dries the cotton cloth, and then the cotton cloth begins to smoke with sparks.
[expert advice]
mandatory installation of overheating protection device "the national standard of hair dryer is relatively broad, and there is no mandatory requirement for hair dryer to have overheating protection device." Huang Yaohua, engineer of the electrical product testing center of Jiangsu Institute of product quality supervision and inspection, said that if there is an overheating protection device, when the temperature exceeds the limit temperature, the hair dryer stops working and enters the protection mode. After the hair dryer cools down, the thermal protection automatically resets and can work normally, which can improve safety.
in the above case, if the hair dryer is turned off but the power is not unplugged, will it also cause a fire? Huang Yaohua told reporters that under normal circumstances, if the hair dryer is turned off, the temperature will soon drop. Even if the power is plugged in, it will not cause a fire. "Of course, there are also many extreme cases. For example, even if the hair dryer is turned off, the temperature is still very high, and there are inflammables nearby, which is easy to cause a fire." He said that sometimes if the hair dryer is a fake and shoddy product and there is a problem with the structure of the hair dryer, it may also cause a fire.
[group rental visit]
there are many hidden dangers of low-cost group rental, especially the use of electrical appliances and wiring boards
in addition to the potential safety hazards of hair dryers, there are also hidden dangers in the fire control of group rental houses. Yesterday afternoon, the reporter of Modern Express came to the place where the fire happened. The whole bungalow is sandwiched in dense tall buildings, and the fire passage is narrow. The bungalow has been renovated, but it is empty. In the nearest high-rise building, there are traces of blackening on the air-conditioning plug-in machine and the wall.
the reporter observed that due to the narrow room and limited sockets, many low-cost group tenants will buy their own wiring boards, and even the wiring boards will be connected to the wiring boards. But some terminal blocks are not of good quality. And like electric car chargers, mobile phone chargers and other plugs, some people usually do not pull out, and the switch of the wiring board is not turned off, which is easy to cause accidents. Another tenant revealed that they use electric blankets in winter, basically do not unplug the power, just turn off the switch. In addition, some people will use the heater, because the room is very small, the heater temperature is too high, and the quilt is almost burnt, which is particularly dangerous.
[precautions for fire prevention of household appliances in winter]
finally, based on the painful lessons of the above events, Xiaobian summarized some points that need to be paid attention to in the process of using household appliances in winter, and we should take precautions in daily life to prevent the occurrence of dangers.
electric fan: the electric fan shall have grounding or neutral protection and adopt three pin plug. Do not touch the wall or other objects when shaking the fan. Generally, electric fans are not used in winter. We'd better clean the fans before collecting them, dry them and keep them in a ventilated place.
washing machine: the household washing machine should have grounding or neutral protection and adopt three pin plug. Do not use wet hands to pull out the plug during use. When dehydration, washing bucket, ferry, mixer and other high-speed operation, it is forbidden to put your hands into the washing bucket. If the motor is stuck or abnormal sound or smell is found during use, the power supply shall be cut off immediately for inspection, and the problem shall be repaired by professionals.
air conditioning: in terms of safety performance, users are required to use special lines for general cold and warm air conditioning, because the power of air conditioning is relatively large, and separate wiring can reduce the impact on other electrical appliances. According to the requirements of electrical safety performance, the air conditioner must have grounding device. It is strictly forbidden to connect the grounding wire with the gas pipe. The reinforcement in the building can be used as the grounding electrode. In addition, the circuit should also be equipped with fuses with corresponding values. Before using the air conditioner, pay attention to check whether the power fuse, watt hour meter and wire have enough margin; Remove the air inlet cover before use to make the air inlet unblocked and prevent fire caused by burning of the air compressor.
electric iron: the electric iron should have grounding or neutral protection. It is best to use a three pin plug to connect the power supply. It cannot be placed on inflammables immediately during use or after use. Cut off the power supply immediately after use to prevent fire caused by high temperature. Do not leave during use.
TV set: it should be placed in a cool and ventilated place, and do not let the sun shine directly. Don't cover the TV cover immediately after the TV is turned off. After the TV is turned on, do not touch the fluorescent screen with a wet cloth or cold water drops to avoid the explosion of the picture tube. In some areas with high humidity or rainy season, the TV should be turned on every day to prevent moisture and damage to internal components. In addition, users must not open the TV cover to check or clean the dust. When the voltage is too high or too low, it is best not to turn on. If the user is equipped with an outdoor antenna, stop receiving in thunderstorm days and unplug the antenna plug. The weather is dry in winter, especially to prevent TV failure.
refrigerator: the refrigerator should be placed in a dry and ventilated place, and pay attention to prevent direct sunlight or close to other heat sources. The refrigerator must be protected by grounding or neutral connection, and the three pin plug should also be used to connect the power supply. The power line shall be far away from the heat source of the compressor to avoid electric leakage caused by burning the insulation.
