Questions and answers about disaster prevention and mitigation knowledge

1 How does tourism deal with mountain torrents? To keep calm at all times and quickly judge the scene environment, we must leave the low-lying areas as soon as possible, immediately look for higher places and choose favorable terrain to avoid.

When the escape transfer fails, you should choose a safer place, stick it on a stable and solid rock or tree and wait for rescue, and constantly send rescue signals to the outside world to get rescue as soon as possible.

It is necessary to maintain collective action with other trapped passengers, obey the instructions of management personnel, and do not act alone to avoid being in a desperate situation.

If you can get out of danger as soon as possible, you should report to the local management department quickly, and take the initiative to obey the command of the relevant local departments and actively participate in the rescue operation.

Under no circumstances can you wade across the river easily.

Never run in the direction of the valley when the flood comes. You should evacuate to the high slopes on the left and right as soon as possible.

The transfer should be quick and timely, and you can abandon the burden when you are in urgent need, and don't be greedy for property, which delays the best hedging time.

If you don't know the contact information of the local tourism department or scenic spot, you can call 1 10, 1 19, 120 for help.

Once the situation is dangerous, you have the obligation to call the police to other tourists in time.

2 What are the omens before the mountain torrents and mudslides break out? Before flash floods and mudslides break out, there are various omens, such as:

(1) When there are unstable factors in the slope near the mountain, landslides and mudslides are easy to occur.

(2) When the rainfall reaches the maximum, the upstream rainfall is strong, the sediment disaster is obvious, and the gullies are abnormally submerged.

(3) When landslides or gullies occur in mountainous areas, trees on the mountains rustle, and the mountain sounds abnormally.

(4) The upstream channel is blocked, and the gully water level drops sharply.

(5) Due to the collapse of the upstream, the running water in the stream is very turbid.

(6) When the running water suddenly increases, the sound in the stream is obviously different from the sound of locomotive, wind and rain, lightning and blasting, which may be caused by the impact of boulders carried by mudslides.

(7) There is a landslide in the upper reaches, and there is an abnormal smell.

(8) There is the sound of trees cracking.

(9) Before people feel abnormal phenomena, animals have abnormal actions, such as the loud bray of cats.

Most of these precursor phenomena of mountain torrents and mudslides are closely related to the intensity of precipitation. Therefore, it is extremely important to do a good job of rainfall forecast in a short time in advance.

How to save yourself from the storm water in the dangerous old houses in low-lying areas? Urban dangerous houses are an important concern to prevent waterlogging disasters. Residents living in dilapidated bungalows should not stay indoors when it rains, but should evacuate quickly to find a safe and solid place to avoid falling into the water. Grassroots organizations such as the community will also organize the safe transfer of residents in dangerous houses for the first time. Residents should obey the arrangement of the organization department, and those who ask for evacuation should evacuate immediately to ensure personal safety.

It is best to choose the nearest highland and roof as a safe haven. Don't panic if it's too late to move. You can move to a high place and wait for rescuers to save you. In the suburbs, if you can't find a tall building, try to move to a higher place.

Residents of dangerous houses should pay attention to the quality of houses at ordinary times, and timely notify the housing management department for maintenance in case of rain leakage and water seepage. At present, many cities have opened housing hotlines. Please call quickly if necessary.

4. What are the household flood prevention products that need to be kept? In order to prevent waterlogging, you need to prepare some items at home. Have you thought about it and done it?

Radio can help us receive weather and flood warning information. Radio may not be commonly used, but most radios use batteries and do not need to be connected to the AC power supply at home, which is very useful in flood control.

Whistling is a tool for us to ask for help, so we must be prepared.

Flashlight can help us evacuate safely at night, and it is also an important distress signal.

Life jackets and lifebuoys are our protective tools to prevent drowning.

What should I do if I find that the power equipment is damaged when a typhoon strikes?

If you see bare wires or electric sparks, or smell burning, you should immediately turn off the switch on the main circuit and consult an electrician.

When the outdoor high-voltage line is found to be inclined or short-circuited, you should immediately call the electric power department to report the accident location and erect obvious signs nearby to prevent people from getting an electric shock.

When going out, if you find that the wire is broken, you should call for emergency repair, protect yourself and remind passers-by to avoid it in time.

What should I do if a typhoon strikes? Under the command of the crew, put on life jackets and board the lifeboats in the order of the old, the weak, the sick and the disabled, women and children to avoid confusion and accidents.

Don't rush when diving. The correct time is not to be hit by others when jumping, not to hit others.

Choose the windward side of the ship, that is, dive against the wind to avoid being hit by a ship drifting with the wind after launching. When the ship leans left and right, it should jump from the bow or stern.

Pay attention to finding floating objects before diving, swim to floating objects after diving and use floating objects to escape.

Try to stay away from the boat after diving to avoid being sucked into the water when the boat sinks.

How to ask for help when trapped by flood? In the hilly environment, whether you are alone or gathering people, if you are suddenly flooded on a platform with a solid foundation or a residential building with a brick-concrete structure, you just have to stick to it in an orderly way, waiting for rescue or waiting for the steep flash floods to subside.

In case of flood, trapped in a low-lying river bank, dry ridge or wooden house, when the situation is critical:

(1) If there are communication conditions, you can use communication tools to report the flood situation and the trapped situation to the local government and flood control department for rescue.

(2) When there is no communication condition, you can set off fireworks, wave brightly colored clothes or call for help collectively, and constantly send out emergency distress signals to the outside world for early rescue.

(3) Actively take self-help measures to find larger floating objects.
