Old City Police Tip: Beware of Fire in Thunderstorm Season

During the summer thunderstorm season, the rain is vigorous, and the electrical lines are eroded by the rain for a long time, which is easy to cause leakage or short circuit and cause fires. In addition, fires caused by chemical hazardous materials leakage, spontaneous ignition of materials due to moisture and lightning are also particularly prominent during thunderstorms. To this end, the police in the old city remind the general public to pay attention to fire and lightning protection during the rainy season, especially to prevent electrical and chemical hazardous materials from leaking, materials from spontaneous combustion due to moisture, and fire accidents caused by lightning.

1. Beware of electrical fires

Thunderstorm weather, often accompanied by thunderstorms and strong winds, can easily lead to short-circuited wires; some old buildings and residential houses have aging wires, which are prone to leakage or short circuit when exposed to moisture. At the same time, due to high air humidity, household appliances are prone to moisture and may bury fires. Hidden dangers.

The police reminded: The general public should timely repair the distribution lines and electrical facilities, replace the old and aging wires in time, and take protective measures such as migration or overhead for wires that are easily immersed in rain. In the event of an electrical fire, the gate should be closed to cut off the electricity, and it is strictly prohibited to use water to extinguish the electrical fire.

2. Be alert to chemical hazards

The activity of some flammable and explosive dangerous goods is enhanced under high temperature and humidity environment. In the storage place with poor ventilation, it often encounters moisture and absorbs water, causing spontaneous combustion. Flooding and low-lying areas in heavy rain weather can easily cause the storage tank to float, incline or rupture the pipeline due to the impact of rain or buoyancy, resulting in the explosion of combustible liquids and gases in case of fire.

The police reminded that places where chemical hazardous materials are produced, stored and used should be equipped with appropriate safety facilities such as ventilation, explosion-proof, cooling, and moisture-proof according to the types and performance of chemical hazardous materials. Chemical dangerous materials that are easy to burn, explode or produce toxic gas in case of fire or moisture shall not be stored in open air, damp, rainy and low-lying places where water can easily accumulate.

3. Be careful of spontaneous combustion

Accumulated too thick cotton, linen, paper and other items, in the case of high water content, due to the action of microorganisms, cause rot, fermentation, fiber decomposition, violent oxidation and release a lot of heat. Without exposure to open flame, it will Spontaneously ignited.

The police reminded: cotton, straw and other production materials must be dried before they can be stacked, and they must be sun-dried frequently to pay attention to moisture; the stack should not be too high, and ventilation holes and spacing should be reserved to allow heat to prevent rapid spread of fire; plant stacking There are many traces before spontaneous combustion, such as steaming, collapse, rats under the stack, and escape of snakes, etc. Once discovered, check in time to prevent fires.

4. Avoid Thunder and Fire

Lightning is a discharge phenomenon that occurs between thunderstorm clouds with positive and negative charges, respectively. The phenomenon of discharge between clouds and ground often causes lightning strike fires in the form of induced lightning strikes and lightning wave intrusion. The main reason for the safety of home appliances during the thunderstorm season is caused by the intrusion of induction thunder. Induced lightning refers to lightning electromagnetic pulses generated on various metal pipes and wires entering buildings when lightning occurs.

The police reminded that social units, especially flammable and explosive places, should strengthen the lightning protection and inspection to ensure that the various devices such as anti-static and lightning protection are complete and easy to use; the general public should not stay on the roof of the building (house) or indoors during thunderstorms. Pay attention to closing doors and windows, turning off the TV power, closed lines and other outdoor cables; unplug the computer power and network cable. In addition, when the thunder and lightning flash, try to unplug all lines from the socket; avoid using solar water heaters, computers, TVs, mobile phones, etc.
