How to Self-Rescue When a Vehicle Submerges in Water?
2 Answers
Vehicle submergence self-rescue methods are: 1. Unfasten the seatbelt and vigorously move limbs; 2. If doors won't open, check central locking system, lift the central lock, activate window controls to lower windows; 3. If electrical short circuits prevent window operation, use sharp tools to strike glass corners; 4. When interior water level approaches head height, push doors open as equalized water pressure facilitates opening. Water ingress consequences include: 1. Mildew and deformation of upholstery and carpets; 2. Short circuits or damage to precision instruments, sensors, and control unit circuits; 3. Component corrosion and rusting; 4. Engine piston and connecting rod damage; 5. Transmission fluid contamination leading to lubrication loss and accelerated mechanical wear.
The first step in vehicle submersion self-rescue is to remain absolutely calm, as panic only wastes precious oxygen and time. I unfasten the seatbelt and avoid blindly pushing the door due to high water pressure making it difficult to open. Prioritizing trying to open the side window, the electric window button lowers it the fastest. If it gets stuck or doesn't respond, immediately find a tool to break the glass; the metal prongs of the headrest are the simplest and easiest accessible window breaker, striking the corner of the window is most effective. When the car first starts to sink, there's enough air, quickly crawl out and swim away. Waiting until the car is nearly full of water makes opening the door easier due to equalized pressure inside and out, but don't delay as the risk increases. Safety equipment is key to survival; I always keep a specialized window-breaking hammer with a cutting knife in my car, and avoid driving through deep water areas in rainy weather to prevent accidents.
