"Electricity" is our inseparable helper
Also a "stealth killer"
One third of the country's fires occur each year
All are caused by electrical causes
About 60% of them are mass fatalities and injuries
The "main culprit" is the electrical fire
Electrical fires refer to:
Due to electrical wiring, electrical equipment, etc
A failure releases a large amount of heat energy
and caused by fire
Causes of electrical fires
01
Short-circuit faults
Electrical equipment will cause short circuits due to insulation damage, circuit disrepair, and operation errors. The heat generated by a short circuit can cause combustion, which can lead to a fire.
02
The line is overloaded
Unreasonable selection of lines or equipment, excessive load current of lines, and long-term overload operation of electrical equipment will cause overheating of lines or equipment and lead to fires.
03
Poor contact
If the joint connection is not firm or tight, the pressure of the moving contact is too small, etc., the contact resistance is too large, and the contact part is overheated and causes a fire.
04
Poor heat dissipation
High-power electrical equipment lacks ventilation and heat dissipation facilities or the ventilation and heat dissipation facilities are damaged, resulting in overheating and causing fires.
05
Unjustified use
For example, the electric heater and electric iron are not used as required, or they forget to disconnect the power supply after use, which will cause overheating and cause fire.
Faced with electrical fires that occur from time to time in life
What can we do to prevent it from happening?
Come and learn it~
👇👇👇
01 Look for the 3C mark when purchasing
When decorating and replacing electrical appliances and wires, it is necessary to buy good quality wires and components, do not buy three-no products because of greed for cheapness, and be vigilant against buying fake and shoddy products.
02Arrange the switchboard reasonably
To install the switchboard in a safe place, do not pile up flammable and combustible materials under the switchboard, and do not replace the thick fuse or replace it with iron wire or copper wire.
03 Electrical wiring is often checked
The wires at home should be replaced in time, and the electrician with the qualification certificate should be found to operate when replacing to prevent accidents caused by improper operation during the replacement, as well as fires caused by short circuits of wires caused by non-compliant connections after replacement.
04Use electrical appliances within the bearing range
According to the thickness of the cross-section, the rated current that the wire can withstand is specified as a safe current carrying capacity, and if the line is overloaded, it will cause a fire, so it is necessary to use electrical appliances within the bearing range of the wire.
05 Refuse to use electrical appliances for a long time
The insulation layer on the surface of household appliances will age after a long time of use and lose its insulating effect. In wet weather, when moisture soaks into the metal conductor, it is easy to cause a short circuit and cause a fire.
06Do not fill the socket with electrical appliances
Ordinary plug-in board, multi-function plug-in board has been the most commonly used circuit transfer connection tool for household appliances, in the purchase of plug-in board, choose quality assurance products. At the same time, pay attention to the two electrical appliances with higher power should not be plugged into the same plug-in board.
07Turn off the power when you leave home
When leaving home, be sure to turn off the power of the electrical appliances, turn off the gas, and cut off the power to prevent the overtime use of the household appliances and cause the body to overheat and catch fire.
