The next scene is also very thrilling, car chaser Allen? A van? Der？ Merwe rushed to the rescue, and the track safety personnel used dry powder fire extinguishers to clear the way for Grosjean. After a short struggle and the help of the staff, Grosjean finally escaped from the fire, leaving the car only 28 seconds after being hit.
Grosjean, who was sent to the hospital for loan, confirmed that he was only slightly burned on his hands and feet and could be discharged after a few days' rest.
Grosson survived such a major collision, but all this needs to be thanked not only for the staff who braved the fire at the scene, but also for all the people who have invested their energy, time and even lives in car safety since the birth of the car a hundred years ago.
Vehicle safety can be said to be advancing in groping. When the first car appeared, we didn't know what car safety was, but when the first driver lost his life driving the car, people began to think about how to design the car to avoid such a danger again.
Chet Miller (Chet? Miller) 1953 accident
1950F 1 When it was first held, racing was born for speed, only for speed. No one has thought about safety, and no one has realized what needs to be done to make vehicles safer. Even the helmet is not mandatory (it was not officially mandatory until 1952, and it is not a full helmet) because the car is safe. In the next ten years, drivers were killed in car accidents.
In the1960s and1970s, one person died or was seriously injured in every ten accidents. During the period of 1980- 1992, the death toll and serious injury rate of each accident decreased significantly to below 250 people 1. So F 1 What happened in these 20 years? Why Grosjean escaped in such a big accident.
FIA has done a lot of work in track safety, driver safety and race safety. The change of F 1 in recent years is also an important foreshadowing for Grossen to avoid a major accident. Including very important safety configuration, such as helmet, fire suit, single cockpit, safety car, pursuit car, track buffer wall (TechPro), headrest, Hans, halo and so on.
In fact, many people may not know that the beginning of modern F 1 is the promotion with safety promotion as the core. 1994 San Marino grand prix, Ayrton Senna, the world's greatest driver? Senna) died in a competition accident, which is undoubtedly a great blow to the F 1 competition, and also sounded the alarm for the safety of the competition again.
After Senna's death, the FIA set up an expert advisory safety committee to study and improve racing safety, and appointed Watkins as its chairman.
Watkins is one of the top neurosurgeons in the world. He has been working in Formula One since 1978, and he was also the owner of Braham at that time.

The Safety Committee cooperates with the Automobile Industry Research Association to enhance the anti-collision performance and restraint system of automobiles and improve the personal safety of drivers. With the promotion of the Committee, the crash test of racing cars is more stringent, and the new safety standards of helmets and racing suits and the final Hans equipment are essential in all international racing competitions. The Committee is also committed to improving the safety of the track. This has also led to many changes in track around the world, including crash barriers, buffer zones and medical equipment beside the track.
Unfortunately, in 20 14, the twentieth year after Senna's death, Bianchi had a serious accident on the track and died after receiving treatment for one year. This is the first driver in F 1 who died in an accident since 1994. Because of this accident, the FIA accelerated the birth of the halo.
Grosjean's collision accident can be said to be very serious in the whole history of F 1, but fortunately he was only slightly injured in the end. What saved his life, but there was a mistake.
First of all, the first point of the accident is collision. After the collision with Coveyat, Graudjean car crashed into the guardrail at the speed of 22 1km/h, and the car disintegrated. At the same time, the cockpit was inserted into the guardrail on the roadside. Secondly, almost at the same time as the collision, the fuel tank of the racing car leaked oil and caught fire instantly. In less than half a minute, rescuers were in place to rescue and the driver climbed out of the car.
This involves the collision safety of the car, the protection of the driver's equipment, the safety of the track buffer and the rescue afterwards.
The most important thing is to ensure the integrity of the passenger compartment to the greatest extent after a serious collision. In F 1 racing car, 198 1 introduced a single cabin design, and the cab was arranged in a single-seat cabin. With the improvement of rigid design and material science, single cockpit can withstand more and more impact and is almost indestructible.
In the 20 18 season, the halo system added in the competition ensured the space at the top of the passenger compartment. After adding the halo, the F 1 racing cockpit is like a cage, which can resist the impact of external objects on people in the car from many angles.
In Grosjean's accident, the cockpit was split and stuck in the middle of the iron guardrail. If there is no halo, the guardrail has a great chance of directly touching the driver. At the same time, in the absence of aura, even if the guardrail does not hurt the driver, it may block the driver's escape space. Halo, on the other hand, "pushed open" the guardrail here, leaving room for residents to escape. At that time, the question about the influence of halo on escape space became insignificant here.

Then, helmet, six-point seat belt, Hans and foldable steering column also play a very important role in this accident if the interior parts of the car are guaranteed not to hurt the driver after a violent collision.
Then there is the driver's fire-proof clothing and the whole body fire-proof materials and equipment. These equipments are all DuPont Nomex coatings, which can ensure fire resistance and prevent heat conduction. After keeping 1 1 second at a high temperature of 600-800 degrees Celsius, the temperature in the racing suit shall not exceed 4 1 degrees Celsius. And this material is used for all items on the driver to ensure that the driver can get enough fire protection in the fire.
The second is car chasing. Generally, the major accidents in the competition occur in the first lap. A medical car that can keep up with the tail car can immediately start rescue in case of serious accidents.
This powerful pursuit car full of life-saving articles and professional medical staff is C63? AMG？ Manor, let the driver Allen? A van? der？ Merwe can arrive at the scene within 10 second after the accident, which plays a key role in the first rescue.
In fact, not all safety devices have played a role, so I have to mention a few bugs here.
Oil tank and oil circuit. F 1 adopts fully flexible fuel tank, which is officially called flexible? Fuel? Bladder. Kevlar material is usually used, and both sides must be covered with fire-resistant elastic coating to meet the requirements of light weight, high strength and fire prevention at the same time. At the same time, the FIA of the oil circuit requires the use of dry-cut joints to prevent the occurrence of Grossman accidents-after the engine and the single shell (fuel tank) are broken into two parts, the fuel will continue to escape through the pipeline.
However, the official reason for the car burning is precisely because of fuel leakage, which is ignited by the burning battery.
So at present, it has not been confirmed whether the fuel tank leaks or the oil pipe leaks, so from the perspective of preventing oil leakage, F 1 still has some bugs.
Wheels. After the collision, it can be seen in the video that one wheel of the car has flown far away and almost hit a passing car in the process of flying out, which is very dangerous.
As early as 1999, the FIA has already added the wheel restraint system to the race case of F 1. The function of the system is to prevent the risk of accidental injury caused by flywheel in collision accidents. 20 1 1 The number of binding ropes per vehicle is doubled to further reduce the flying of tire parts after the accident. Nevertheless, the system failed in this accident.
The buffer wall TechPro is at 1967. In order to prevent fire, the FIA banned the use of haystacks as protective walls. Later, in 2000, TechPro was introduced, which is a special buffer wall for the current track. F 1？ TecPro has the largest energy absorption capacity and was developed according to the speed of modern Formula One racing cars. Its real efficiency lies in the fact that the system will not disintegrate in the event of a collision, nor will it be pierced by any type of vehicle.
But! ! ! !
Because the collision site of Grosjean is not a regular accident site, the TechPro wall is not used. Although F 1 has been very strict in the layout of track safety, accidents are unexpected.
Also in this year's F2 Russian station, Ghiotto and Aitken had a serious collision and flew out of the track at the No.4 high-speed corner, but thanks to the impact energy absorbed by TechPro, neither driver was injured. This also proves that TechPro plays a very important role in collision safety, but it is a pity that the accident site in Bahrain station was not affected by TechPro this year, which led to the deterioration of the accident.
As early as 20 18, F2 champion Russell called on the audience to use TechPro. After all, accidents always come unexpectedly.
In fact, there are sad stories behind the introduction and use of our very common security technologies. For example, Bianchi's accident promoted the birth of the halo. When writing this article, I read a lot of information, and I was particularly sad in the process, but I was also particularly fortunate.
Sadly, in this process, the tragic cases repeated again and again in front of my eyes are repeated again and again. Fortunately, I live in this era, and we also live in this era. We have gathered the wisdom and experience of all our predecessors and built a car that we can touch and drive today, the safest configuration ever. Therefore, please make good use of all the safety equipment that can fully protect us, because this era has given us the most precious gift.
