What are the precautions in a thunderstorm room?
What are the precautions in thunderstorm weather? Although it is safer indoors in thunderstorm weather, there are still many things to pay attention to. The following is some information I have compiled for you about the precautions in thunderstorm weather. Let's have a look!
What are the precautions in thunderstorm weather 1
Some citizens choose to use solar water heaters. Most solar water heaters installed on the roof have no grounding wire and no lightning protection facilities. Some solar water heaters even built high iron frames to get good lighting. When it rains, the water heater may become a lightning rod, causing lightning strikes.
Many people remember to use electronic products as little as possible in a thunderstorm, but now it depends on the weather to take a bath. Try not to take a bath with a solar water heater in a thunderstorm.
The solar water heater is installed at the top of the building. If the lightning protection device is not perfect, it will become an induction lightning device and play the role of lightning. Especially in rural areas, there is a lack of lightning protection measures at the top of buildings, and the solar water heater installed at the top of the roof is completely exposed to direct lightning.
If there is no effective lightning protection, once struck by lightning, not only the solar water heater will be damaged, but also the lightning current will enter the bathroom and indoor wire network along the water pipes and power lines, which may cause damage to indoor appliances and personal injury.
Is it dangerous to play computer in thunderstorm weather?
Don't be afraid of thunder in the distance, but pay attention to thunder nearby. Because the lightning protection measures of high-rise buildings are relatively perfect, it is rare for lightning to directly hit indoor computers, and lightning generally enters the room from power lines or signal lines.
Because high-rise buildings have relatively perfect lightning protection measures, users in buildings generally do not need to consider lightning protection from the perspective of power supply, but once lightning strikes the outdoor power line, your computer will suffer.
Signal line intrusion is mainly caused by lightning surge caused by induced lightning. Induction lightning generally comes from lightning strike to the ground and cloud-to-cloud discharge, among which the induced surge voltage generated by lightning strike to the ground is large, and electronic information equipment within 500 meters may be damaged by it. According to the theory and practical experience of lightning electromagnetic pulse, it is proved that the damage of electronic computers and other information equipment is mainly caused by lightning induced surge voltage, which can introduce the induced surge voltage wave into the equipment through various signal leads and destroy its chips and interfaces.
So before the rainy season comes every year, check and install the outdoor lightning arrester. I suggest you turn off the computer when it thunders nearby, unplug the power plug of the computer from the socket, unplug the telephone line from the "cat" and plug it back after the thunderstorm, just in case.
Thunderstorm weather room 2 1, what are the precautions before thunderstorm and flood:
1. The office and bedroom houses of the project department should not be selected in low-lying areas or areas threatened by landslides. Every early summer, we should check the front and back of the house, pay attention to the changes of the nearby mountains, see if there are signs of cracks and landslides on the mountains, and check the deformation of the foundation and the house itself. If the rain is heavy, check whether there is water around the house and whether the drainage is smooth to prevent flash floods from hitting or soaking the house; Understand the direction and location of evacuation in an emergency.
2, check the power lines and facilities, low-lying areas should focus on inspection, take corresponding preventive measures, for disrepair, aging and can not be replaced in time lines and facilities, should be closed in advance.
3. Employees should avoid going out and be prepared to prevent thunderstorms. Employees should stay away from dangerous building facilities (such as dangerous buildings, walls, billboards, etc.). When walking and driving a vehicle, you should bypass when encountering low-lying water to avoid forced passage.
2. After the thunderstorm and flood:
1. When a major thunderstorm or flood sign is found or a thunderstorm or flood disaster has occurred, the person in charge of the project department should calmly and decisively respond. When rescue is needed to prevent and delay the danger and expand the disaster, the information should be transmitted as soon as possible to attract the attention of the higher authorities and strive for rescue, or call 1 10 and 65438+ in time.
In an emergency, employees should act calmly and quickly. Thunderstorms and floods come suddenly and steeply, but for a long time. When you find that the river is flooded when you are working in the river or about to cross the river, you should evacuate quickly and don't hesitate. In flood season, when the river overflows, never cross the river by force. Wait patiently for the river to recede, or cross the river around a distance.
3. In case of thunderstorm and flood, employees should stay away from high-voltage lines, poles (towers, electrical equipment and other dangerous areas. ). Turn off the phone when necessary. Enterprises should retain employees to avoid thunderstorms and floods, arrange temporary accommodation, and employees should inform their families in time.
4. Employees working outdoors should take shelter from the rain nearby, and vehicles should choose a safe driving route or park in a safe place nearby.
5. When the water depth is close to the vehicle chassis, the driver and passengers should land on their feet at the same time when getting off the vehicle, and leave the vehicle quickly to a safe place.
6. When the water depth in the house will reach the minimum height of power socket or before live equipment, the power supply should be cut off immediately.
