In the past few days, the precipitation in the province has increased
The air also started to get humid
Many people think
Rainy and humid environments are less prone to fire
This is not the case
Dampness is also a household appliance
One of the most feared "invisible killers".
Cautionary case 1
On February 21, 2022, a fire broke out in a board house in Zhongshan, Guangdong. According to the investigation, the cause of the accident was a leakage of water from the roof of the board house on a rainy day, which dripped onto the socket and caused a short circuit in the line and a fire.
Cautionary case 2
On December 15, 2022, a fire accident occurred in Beigang, Hubei Province, and three shops were burned. According to the investigation, the cause of the accident was the aging and broken skin of the wire, coupled with the continuous rainy weather caused by the short circuit of the wire and the fire.
Why the weather is humid
Is the chance of an electrical fire increasing?
First of all, we need to know
Rain just increases the humidity of the air
It does not reduce the occurrence of fires
The main causes of fires in rainy weather are as follows
Impurities become conductors. Due to the humidity of the air, the dust impurities in the electrical appliances become excellent conductors due to moisture, and the soaked dust impurities are easily broken down by the current in the energized state, thus causing combustion.
Aging lines. High humidity can easily lead to corrosion of internal metal components and circuits of electrical appliances, especially some elderly electrical appliances that have been in service for a long time, aging of internal components, wear and tear of some exposed lines, and are prone to short circuit ignition in the case of long-term erosion by water vapor.
The power plug is not in good contact. The power plug is in poor contact, and the air is humid, which can easily lead to changes in the conductive parameters between the poles, and leakage, short circuit, ignition and other phenomena may occur.
Rainy days increase the humidity of the air
This increases the fire risk factor
It is easy to cause accidents such as leakage, electrical short circuit and fire
So how to prevent fire on a rainy day?
Let's take a look!
