I heard that you like road trip. You should know the knowledge of vehicles and first aid measures! Where there are preventive measures.

In recent years, go on road trip has become more and more popular. Many people like to bring their relatives and friends, go on road trip. But at the same time, there are more and more reports about the accident in road trip.

So, how can we ensure the safety of traveling on the road to the greatest extent and let ourselves and our peers have a pleasant travel time?

Preparation before departure

1. Vehicle inspection. There are two aspects that are easily overlooked. The first is the inspection of tires. It mainly includes tire pressure, tread scar, tread pattern depth, etc. At the same time, in order to prevent the tire from bursting at high temperature, you can also choose to empty the air in the tire in summer and then fill it with inert gas nitrogen.

Second, replace the coolant. Because driving often involves a long distance, the running time of the engine is relatively prolonged, and the requirements for coolant will also rise. Comrades who usually use tap water instead of coolant should be cautious and use special coolant.

2. Analyze the road conditions along the way. It is believed that many people will do their homework before going out, but in order to prevent accidents, it is best to plan more than two routes as alternatives. At the same time, it is necessary to find out the approximate location of gas stations and repair shops along the way, and try to fill up the fuel tank when there is about one third of oil left.

3. Prepare emergency reserve box. Bian Xiao suggested that the storage box should at least include food and water, first-aid medicine, charging treasure and data cable. Of course, if you want to experience the fun of car cross-country, then in addition to the conventional items mentioned above, car navigation, xenon lights, tow ropes, emergency lights, tire repair tools and so on. You may need these things.

Common problems in driving and common sense of self-help

Situation 1: fire. Although the probability of car fire is relatively low, it is very necessary to learn fire prevention knowledge if your car happens to be a new energy vehicle with poor quality or some problems in circuit design. Once the car catches fire while driving, you should immediately turn off the engine, cut off the oil and power supply, turn off the blinds and ignition switch, pull over as soon as possible on the premise of being as safe as possible, organize personnel to stay away from the burning car as soon as possible, and call the fire alarm immediately.

Situation 2: falling into the water. After the car falls into the water, if the water is shallow, try to leave the car after the car is stable. If the water is deep, it is difficult to open the door at this time. Passengers had better try to break the glass to escape, but one thing should be noted. If the door can't be opened during drowning, don't panic at this time to avoid consuming physical strength and oxygen, because under normal circumstances, the car will be completely filled with water after 1 to 2 minutes.

Situation 3: collision. When a collision accident happens, drivers and passengers had better take different countermeasures. For the driver, he should hold the steering wheel with both hands, hook the pedal with both feet, lean back, try to be relatively stable and reduce accidental injuries. For passengers, in the event of an accident, try to protect important parts such as the head, and remember to fasten your seat belt when going out by car.

Situation 4: Flat tire. If your vehicle is a front wheel, what you need to do after the rear wheel has a flat tire is to park your car in a safer place, and then get off to change the tire or wait for rescue. However, if the front wheel has a flat tire, the car is very easy to lose balance at this time, so you need to hold the steering wheel immediately and straighten the steering wheel in the opposite direction of the flat tire, and pay attention to slowly collecting oil until the car regains its balance and stops.

Situation 5: The battery is dead. In addition to the emergency power supply and traction rescue equipment in the car, you can also quickly connect the wires so that the electric car can get electricity for the electric car, thus getting out of trouble. Generally speaking, quick wiring is divided into red line and black line. One end of the red line is connected with the positive pole of the trolley battery, and the other end is connected with the positive pole of the trolley battery. One end of the black line is connected to the negative electrode of the tram battery, and the other end is connected to the metal part of the tram. This connection is good. After the tram starts running, you can take the tram with you.

How do the wounded save themselves

1, First Aid for Patients with Hemorrhage and Fracture

If the personal injury is minor, only a small amount of bleeding occurs on the skin surface, clean fabric or gauze can be used for dressing and spraying to stop bleeding, and efforts should be made to press the bleeding blood vessels to stop bleeding. But pay attention to limb bleeding. Generally, the dressing should be close to the heart, and the bandage should be tied for one hour and relaxed for five minutes to avoid limb ischemia and necrosis. In case of fracture, try to avoid moving the wounded, and try to fix the wounded body with wooden bars and other objects.

2. First aid for the injured in the collision

In case of collision injury, it is necessary to reduce the rough movements of the injured person, move the injured person as gently as possible, avoid lifting and hug, and move the injured person to the supine position. After fixing the neck, several people work together to lift the injured person to a stretcher or a board, with his head behind and his feet in front, and then transport him to an ambulance smoothly.

3, it is forbidden to give the wounded drinking water and use drugs for analgesia.

In order to reduce bleeding, once an injury occurs, it is forbidden to give the wounded any drinks and tea. Because most of the wounded must be treated immediately, drinking water or drinks will make the operation more difficult. For the wounded in coma, shock or respiratory tract injury, morphine is strictly prohibited to relieve pain, so as not to suppress breathing and cover up the injury.

How to deal with extreme weather

1, rainstorm weather. If heavy rain causes sudden floods, first of all, we should pay attention to avoid low-lying areas and try to park in higher places. If the water potential is low and the surrounding terrain is relatively flat, you should call the police immediately, accurately report your position, and climb to the top of the building to wait for rescue.

2. Extreme cold and blizzard weather. It's easy to open the door in extremely cold weather. At this time, the ice can be melted by heating with a lighter, or a little lubricating oil can be injected into the lock hole of the car door in advance, and a thin layer of grease can be coated on the sealing strip around the car door to avoid freezing the car door. Another situation that is easy to happen is the difficulty in starting. In this case, you can choose to play for a while, but the single start time should be controlled within 5 seconds. You can also take the battery out and keep it indoors for heat preservation, and then use it after the battery temperature is restored.

Although it seems that the threshold is not high, traveling on the road itself still needs experience. For example, the accident we mentioned earlier happened on a mountain road. If it's the first time to drive a mountain road, it's best to be accompanied by an old driver. At the same time, you should also make preparations in advance, understand the road conditions of tourist routes, read more common sense and self-driving knowledge, and finally hope that the lost children can be found early and pray that they can return safely. I hope everyone's journey is smooth and smooth.
