In the fourth quarter of 2010, the Fire Department of the Ministry of Public Security informed the Chinese fire situation in 2010. From the direct cause of fire, electrical fires ranked first; followed by fire carelessness; third, children play with fire. Looking back at previous years' data, in the past 10 years, the number of electrical fires in China has topped the total number of fire accidents. In 2007, a total of 159,000 fires occurred (excluding forests, grasslands, military, and mine underground fires, the same below). Electrical fires caused the most fires, with a total of 45,703 incidents, accounting for 28.8% of the total; in 2008, a total of 133,000 fires occurred. Short circuit, overload, electrical equipment failure and other electrical causes caused 40,000 fires, accounting for 30.1% of the total. The proportion increased by 1.3 percentage points over 2007. In foreign countries, such as Japan, electricity consumption is 8 times that of China, but electrical fires only account for 2% of the total number of fires.
Inadequate policies and regulations lead to high electrical fires
Some people think that the reason why the proportion of electrical fires in Japan is low is due to the Japanese government’s introduction of a mandatory policy in 1978 to install electrical fire forecasting, warning, and forecasting systems that can eliminate hidden dangers before electrical fires occur. Although the Chinese government attaches great importance to electrical fire prevention work, it is always a matter of luck because the people’s awareness of electrical fire prevention is not high, resulting in incomplete rectification.
The new Fire Protection Law, which came into effect on May 1, 2009, stipulates in Article 66 that the installation and use of electrical and gas appliances, as well as the design, laying, maintenance, and testing of their circuits and pipelines, do not comply with the fire control system. If the technical standards and management regulations are prescribed, they shall be ordered to make corrections within a time limit; if they do not correct after the deadline, they shall be ordered to stop using them, and a fine of more than 1,000 yuan but less than 5,000 yuan may be imposed concurrently. After the introduction of the policy, look at China's fire situation this year, the first eight months of the survey report shows that electrical fire still ranked first. It can be seen that non-mandatory policies and regulations do not have an immediate effect.
Advanced electrical fire monitoring and detection technology can effectively reduce accidents
There is also a view that, in contrast to developed countries, China is in a period of economic development and is still lagging behind in the field of electrical fire monitoring technology. Therefore, even if policies and regulations are issued, the hardware products cannot keep up, and the problem of high electrical fires cannot be solved effectively.
When we understand the principle of the electrical fire monitoring system, it is actually the system that can send out alarm signals, control signals and can indicate the location of the alarm when the detected parameters in the protected circuit exceed the alarm setting value. It consists of electrical fire monitoring equipment. (Can receive the alarm signal from the electrical fire monitoring detector, send the sound and light alarm signal and control signal, indicate the alarm location, record and save the alarm information device) and the electrical fire monitoring detector (detect the residual current in the protected circuit, The temperature and other electrical fire hazard parameters are defended by detectors). The monitoring system technology based on this principle is not a highly sophisticated technology field. The current technology can accurately monitor the faults and abnormalities of the electrical lines, and record and save them in a timely manner. At the same time, the hidden dangers of electrical fires can be discovered. These hidden dangers. The level of science and technology in our country can fully meet international standards. At present, many companies in the fire protection industry in China are doing very well in the field of electrical fire alarm systems. Some companies' products have gone abroad. It can be said that China's electrical fire monitoring and detection technology has reached a level that can effectively control the accident.
How can we effectively control the incidence of electrical fire in China?
National cooperation to strengthen fire awareness is fundamental to reducing electrical fires
For the prevention of electrical fires, it is not as simple as using fires and other fire prevention. Electrical fires often occur with uncertainties. The number of involved personnel is also very large. From the construction of houses, the use of electrical appliances of personnel, the regulation methods of the power supply department, etc. All may be the cause of electrical fires. Therefore, the people's awareness of fire prevention and prevention at all levels are in place. Increase the detection of electrical lines. In the daily fire supervision and inspection, supervisors of public security and fire control agencies shall give full play to the function of the electrical inspection intermediary organization, and regular inspection shall be conducted on the electrical lines installed and used by relevant units and places. In particular, some new public gathering places must be qualified for electrical testing before they can be opened before they can be allowed to start business. At the same time, a regular electrical safety inspection system should be established for the public gathering place in use so that it can not only detect the aging, damage, and disorderly connection of the electrical lines in time, but also prevent the occurrence of fire accidents.
2. Establish a good collaboration relationship between users and power supply departments. As a user, the electrical circuit installed in the power supply department cannot arbitrarily change the original design or laying function, and should promptly report the problem to the power supply department in order to promptly repair and ensure safe use. For the power supply department, the installation and maintenance of electrical lines must be strictly in accordance with the relevant provisions on electricity use, and the terms of the contract or agreement should be carefully performed. In addition to regular inspections and maintenance of public lines, they must be irregular. The above-ground gates provide users with the services of safe power management and maintenance, ensuring that if a dangerous situation arises, they will be eliminated in a timely manner and the responsibility disputes between the two sides in power consumption management will be reduced. At the same time, power-using units and sites should use personnel with strong sense of responsibility and comprehensive technical skills as electrician operators, and be trained by relevant departments to obtain corresponding qualifications.
3. Standardize the construction and installation of electrical circuits. The selection of electrical lines should be in accordance with the requirements of the site and equipment, according to the size of the different power devices to choose the size of the wire, according to different locations to choose explosion-proof, waterproof and other electrical circuits, to ensure the normal operation of the line to prevent the insulation aging of the line And other undesirable phenomena. At the same time, during the laying of electrical circuits, the protection must be completely worn when laying concealed or passing flammable materials, and metal tubes must be worn when laying in flammable and explosive places. In the selection of electrical circuits, qualified products that are produced by regular manufacturers should be used, and corresponding electrical circuits should be selected according to different places and different equipment. In general places, the use of easily-aged electrical circuits such as polyvinyl chloride and aluminum cores should be avoided.
Such comprehensive cooperation is a good way to completely reduce electrical fires.
Now is the arrival of the 20th 119th Day of Fire in our country. The fire departments of all regions are vigorously implementing firefighting propaganda. We will make electric fire propaganda knowledge and education a reality. We will take firefighting awareness deep into the hearts of the people, and the whole nation will take preventive measures and cooperate with it. The construction laws and regulations of the state can only reduce the high incidence of electrical fire. This requires a long-term process, but it is also a process that must be experienced.
