[Explanation] Recently, many places across the country have encountered extreme weather such as heavy rains, and incidents of vehicles being soaked in heavy rains have occurred from time to time. If the heavy rains continue and the vehicles are at risk of being submerged, how to safely escape and save themselves?
Recently, the Nanning City Fire Rescue Detachment of Guangxi carefully planned an experiment: simulating the real scene of a vehicle being soaked in heavy rain, firefighters personally tested the escape routes and measures at different water levels.
[Explanation] In the experiment, it was first tested that when the water level reached the position of 1/2 of the tire of the vehicle, the firefighters in the vehicle tried to open the doors and windows and found that they could be opened, and the time for escape was relatively sufficient. This is also the best way to escape. opportunity.
When the water level rises to the position of the door handle, due to the short circuit of the car's circuit system, the electronic components fail, the door lock is automatically locked, and the door cannot be opened due to the pressure difference due to the different water levels inside and outside the car. At this time, the firefighter explained in detail How to use the tools at hand to escape at this time.
[Simulation scene] It is perpendicular to the glass, so it can be broken by pressing down perpendicular to the glass.
(If this point is not suitable, you can try a few more points, basically the edges of the four corners are the best.)
[Explanation] When the water level rises to half of the car window, the firefighter reminds, don’t panic at this time, first keep calm and store your energy. The compartment will not be filled with water in a short time. There is still some oxygen in the car to maintain escape .
Don't try to open the car door lightly. The underwater pressure is very high. At this time, it is almost impossible to try to open the car door.
[Explanation] Later, firefighters also tested the use of car seat headrests, safety hammers, window breakers and other equipment and tools to break the windows of the car to inspect the degree of damage to the car windows by different hard objects.
[Explanation] Through this simulation experiment, firefighters summarized the "four-character trick" for self-rescue vehicles trapped in the water: hit, smash, fast, and escape.
Fighting: It means to seize the "golden time" for self-rescue by escaping and opening the doors and windows as soon as the water level is still low.
Smashing: When water floods into the car and the car’s circuits fail to open the doors and windows, use all the sharp objects around you to smash the windows of the car. It is best to keep a safety hammer or a window breaker in the car.
Quick: It means to stay calm and act as soon as possible. Don't panic, hesitate, and miss the best time to escape.
Escape: After leaving the submerged vehicle, you must quickly escape from the compartment and follow the direction of the bubble rising to the surface of the water, seeking rescue.
[Explanation] Nanning Fire Remind the majority of car owners: pay attention to the weather forecast before traveling, pay attention to the weather conditions, and quickly carry out self-rescue and escape in distress. Life safety is the top priority.
