The flood season has arrived! There may be a "big pit" under the calm water surface. What should you do if you accidentally drown?

Recently, a couple in Yuncheng City, Shanxi Province, fell into the Yellow River Diversion Canal near the Jie Village Bridge and drowned.

Some seemingly calm wild waters are actually fraught with danger. Especially now that the flood season has arrived, some rivers will lower their water levels in advance, which is often called "releasing water". At this time, the water is turbulent, and if the public rashly wade in the water, the consequences will be disastrous.

my country's flood season begins 17 days earlier than usual this year

According to the Ministry of Water Resources, from March 12 to 15, heavy rainfall occurred in Jiangxi, Fujian, Zhejiang and other places in southern my country. The accumulated rainfall for three consecutive days exceeded 50 mm, covering an area of ​​173,000 square kilometers.

According to the "Notice of the Ministry of Water Resources on Issuing the Method for Determining the Flood Season Date in my country", this year's flood season date in my country is March 15, which is 17 days earlier than the average flood season date in many years (April 1).

The flood season has arrived. Beware of the "undercurrent" beneath the calm water surface

▲ Underwater rocks and undercurrents

Even if there is no height difference in the water area, when the water hits the large rocks and accumulated stones in the river, the flow direction will change, and it is possible to form a strong undercurrent or even a whirlpool.

There are not only rocks under the water, but also water plants and mud. If you step into the mud or get entangled in water plants after wading, you will also be at risk of drowning.

▲The first step is shallow, the next step is deep

The riverbed structure of most rivers is uneven, and the water depth varies. If you wade rashly, you may easily step into deep water and drown.

▲If there is heavy rain upstream, be careful of flooding downstream

Sometimes, even if the weather downstream is fine, if there is heavy rain upstream, the water volume of the river will increase rapidly, forming a turbulent current rushing downstream. People in the water have no time to escape and are swept away by the river.

In addition, people often overlook the refraction of water, and the water level seen from the shore is shallower than the actual water level. In other words, what you think is a "shallow water area" may actually be an "abyss".

After drowning, don't struggle in the water

The most important thing after drowning is to adjust your mentality, don't be anxious, try to calm down, and don't struggle in the water. Because the density of the human body is slightly greater than the density of water, the more you struggle in the water, the faster your body sinks. Remember that "the head will sink if your hands are out of the water."

▲How to save yourself from drowning?

Hold your breath, hands in front of you

Tilt your head back and breathe through your mouth

Keep your hands close to the water and reach them above your head.

Mandible tilted upward, knees slightly flexed

In addition, pay attention to whether there are any items around you that can help you float. You can hold buoyant items such as empty plastic bottles in front of you to help you float even more.

If you fall into water with fast current, this self-rescue method will not apply. The person can float with the current and quickly grab any object that can fix the body, such as a tree, and wait for rescue.

▲How to rescue if you see someone drowning?

Rescuers must analyze the situation calmly at this time and not jump into the water directly or hold hands to rescue. Because once a "human chain" is formed, if someone breaks the "balance" due to exhaustion, many people will fall into the water, which may easily lead to mass deaths and injuries.

Rescue can be carried out on shore by shouting, stretching and throwing.

"Call": call for help loudly and seek help from more people around;

"Call": Dial 110, 119, 120, etc. for help;

"Reach": While ensuring your own safety, pass branches, sticks, bamboo poles, etc. to the person who falls into the water;

"Throw": Throw floating objects such as foam blocks, lifebuoys, sealed empty plastic bottles, etc. to the drowning person to help him float and wait for help.

If the conditions for diving into the water for rescue are met, the rescuer should approach the drowning person from behind, then lift up his body, keep his head out of the water, and swim sideways to the shore.

Ke Ke reminds: Our country has now entered the flood season. The underwater situation is complicated, and emergencies and accidents occur from time to time. Don't be deceived by the calm water surface and do not wade rashly.
