It's hot
The frequency of use of air conditioners began to rise dramatically
But the air conditioning brings coolness at the same time
There are also safety risks
!
Fire hazards
01
Instantaneous power on after power failure
The air conditioner is energized instantaneously after the power is off, and the internal air pressure of the compressor is very large, which makes it difficult to start the motor, and the large current generated is easy to cause the circuit to catch fire.
02
The air conditioner capacitor is damaged
The capacitor is heated and damp, the insulation performance is reduced, and the leakage generates sparks, which in turn ignites the combustible materials in the machine and causes fires.
03
The power supply is not safe
When installing an air conditioner, connect the air conditioner directly to a power circuit without a safety device, which poses a fire hazard.
04
Mechanical malfunction of the air conditioner
The centrifugal fan of the air conditioner gets stuck due to mechanical failure, which will cause the temperature of the fan motor to rise, overheat and catch fire.
05
Air conditioners are in service over age
The service life of household air conditioners is about 10 years, and the internal circuits of air conditioners that are in service over age are aging, which is easy to cause short circuits and fires.
06
Improper use of the external unit
Because the outdoor unit is placed outdoors for a long time, it is exposed to sunlight for a long time, and the temperature itself is high, and if it encounters an open flame at this time, it is easy to cause spontaneous combustion.

Fire prevention measures
in everyday life
I want to prevent an air conditioner from catching fire
This brings us to the correct "posture" for using the air conditioner
The installation position, height and direction of the air conditioner should be conducive to air circulation and heat dissipation, and pay attention to keeping a certain distance from combustibles such as curtains.
The air conditioner should have a separate fuse and power socket if the power is large, do not share a socket with other household appliances, and the power cord of the air conditioner should be protected by pipes.
When using the air conditioner, it should be operated under supervision, and the power of the air conditioner should be cut off when going out. Do not cut off or turn on the power of the air conditioner continuously in a short period of time.
The air conditioner should be maintained regularly, and the condenser, evaporator, filter, and heat exchanger of the air conditioner should be cleaned regularly to wipe off the dust and prevent the radiator from clogging.
In thunderstorms, it is necessary to turn off the air conditioner in time, because the air conditioner does not have the lightning protection function, it is difficult for the air conditioner installed on the high-rise building to avoid lightning attack.
Users should not pile up debris near the air conditioner; Residents on the upper floors should not throw lit cigarette butts, matchsticks and other objects with open flames downward.

Coping methods
If the air conditioning in the home is due to
High temperature, aging, short circuit, etc
Don't panic
Call the police on 119 in time
After the alarm, the power supply should be cut off quickly, and a dry chemical fire extinguisher should be used to extinguish the fire. In the absence of cutting off the power supply, do not extinguish electrical fires with water or foam fire extinguishers, otherwise there is a risk of electric shock. If you find that the fire is large and cannot be controlled, you should immediately evacuate to a safe place.
