The prevention of electrical fires includes four aspects: one is the selection of electrical appliances, the second is the selection of wires, the third is installation and use, and the fourth is not to use high-power electrical appliances without authorization. For electrical appliances, the qualified products produced by the manufacturer should be selected, the installation should comply with the regulations, the use should be in accordance with the requirements of the manual, and the wires should not be pulled randomly. When the teaching work requires the use of high-power electrical appliances, professional electricians should be invited to install special circuits, and they should not be mixed with other electrical appliances at the same time. Turn off the power supply when it is not normally used.
The following is a list of some common electrical appliances fire prevention:
(1) Fire prevention measures for TV sets
If you turn on the TV for 4-5 hours in a row, you need to shut down and rest for a while, especially when the temperature is high. Keep away from heat sources and do not cover the TV with a TV cover when watching TV. Prevent liquids or insects from entering the TV. The outdoor antenna must have lightning protection devices and grounding facilities. Do not turn on the TV when using the outdoor antenna during thunderstorms. Turn off the power when not watching TV.
(2) Fire prevention measures for washing machines
Do not let the motor enter the water and short-circuit, do not cause the motor to become overheated and catch fire due to excessive clothes or hard objects stuck on the motor, and do not use gasoline or ethanol to clean the dirt on the motor.
(3) Refrigerator fire prevention measures
The refrigerator radiator temperature is very high, do not put flammable items behind the refrigerator. Do not store flammable liquids such as ethanol in the refrigerator because sparks are generated when the refrigerator is started. Do not wash the refrigerator with water to avoid short-circuiting and igniting the refrigerator components.
(4) Fire prevention measures for electric mattresses
Do not fold to avoid damage to the wire insulation, which could cause a short circuit and cause a fire. Do not use the electric blanket for a long time, and be sure to turn off the power when leaving to avoid overheating and fire.
(5) Fire prevention measures for electric irons
Electric irons are very hot and can ignite common substances. Therefore, there must be a special person to take care of the electric iron when using it. The power-on time should not be too long. After use, it must be cut off and placed on a heat-insulated shelf to cool down naturally to prevent the residual heat from causing a fire.
(6) Fire prevention measures for microcomputers
Prevent moisture and liquid from entering the computer, and prevent insects from climbing into the computer. The use time of the computer should not be too long, and the cooling window of the fan should keep the air unobstructed. Do not touch heat sources and keep the interface plugs in good contact. Pay attention to eliminate hidden dangers. The electrical circuits and equipment in the computer room are many and complex, and the materials are mostly flammable materials. Problems such as crowding, high mobility, and chaotic management are all hidden dangers, and preventive measures should be implemented in a targeted manner.
(7) Fire prevention measures for lamps and lanterns
When the switches, sockets and lighting fixtures of lamps and lanterns are close to combustibles, measures for heat insulation and heat dissipation should be ensured. When the current passes through the incandescent lamp, it can generate high temperature of 2000-3000 degrees Celsius and emit light. Since the bulb is filled with inert gas to conduct heat, the temperature of the glass surface is also very high. The higher the power, the faster the temperature rises. The distance of combustibles should be greater than 0.5 meters, and no combustibles should be placed under the bulb. When reading and studying at night, do not put lighting fixtures on the bedding.
