How to use triangle warning signs and safety vests?
The so-called necessary small skills, naturally, we do not need to prepare any tools in advance, only need to use the accessories and tools that come with the vehicle. Of course, we also need to master certain skills or skills, so that we can quickly respond to or solve some difficult problems in unexpected situations.
First of all, we want to introduce the first small Tip, which is also the most basic and important, how to correctly place the triangle warning sign? As we all know, no matter how big or small a traffic accident occurs, the most important thing is to prevent the occurrence of secondary accidents and derivative accidents under the premise of ensuring the safety of the people in the car of both sides of the accident, in the words we often say now, "stop loss in time". How to place the triangle warning sign, perhaps in theory, everyone has been very clear, is nothing more than three sentences taught by the coach when driving the school to learn the car: "50 meters during the day, 100 meters at night, 150 meters on the highway." "And on the road to true openness, there are still many issues that need to be paid attention to. Next, I will take you to take a look at what problems need to be paid attention to in addition to the placement rules.
First of all, everyone is already familiar with the provisions on the placement of triangle signs in traffic laws, but in special circumstances, we still have to adapt to local conditions. For example, if we encounter wind, frost, rain, snow, fog or other extreme weather, the distance of the triangle card should also be appropriately increased to 80 meters, 120 meters, 150 meters, 200 meters or more.
How to judge whether the placement distance is appropriate? The one-step distance (hind heel- forefoot tip) for adult males is about 45-60 cm, and for adult women is generally 40-50 cm. That is to say, in the city road in normal weather, we walk 80-100 steps to the rear of the accident vehicle, and the position is about 50 meters.
The reason why the four words of local conditions mentioned above are because in many cases, the distance stipulated by the regulations can only ensure that you have placed a triangle warning sign in accordance with the regulations, and it cannot be guaranteed that such a way is the most in line with the on-site safety specifications. For example, when our car is involved in a traffic accident under a mountain road bend or arched bridge slope, then we must put the triangle warning sign on the safety and full position before entering the bend and on the uphill slope to prompt the rear driver to avoid and slow down in time. This not only avoids the occurrence of secondary accidents or derivative accidents, but also prompts the driver of the rear car to merge in advance to prevent the rear car from being unable to find the accident in front of it at the first time, and the emergency parallel line leads to the occurrence of large-scale congestion.
In addition to the triangle warning signs, there is also a small accessory that we often overlook in the car - the reflective vest. Since January 1, 2018, reflective vests have been included in one of the mandatory accessories in the car, which is the first time that the mainland has included reflective vests in vehicle safety standards. Therefore, cars leaving the factory after December 31, 2017 will be equipped with a reflective vest as standard. And from January 1, 2018 onwards, all cars need to show reflective vests to pass the inspection during the annual inspection. Don't look at this little thing every car has, but will you really use it?
In fact, many friends have a misunderstanding when using reflective vests, thinking that reflective vests only need to be used at night, and there is no need to use reflective vests when the line of sight is good during the day. In fact, this is also the wrong idea, reflective vests are very useful not only at night, but also during the day. For example, if we are driving on a highway, the vehicle breaks down due to a flat tire, no oil or a traffic accident. We'd better wear reflective vests during the day and at night. Because most of the highways are very open, the driver will inevitably lead to a decrease in concentration after a long time of driving, when you push the car on the highway or repair the vehicle, it is easy due to the rear driver's lack of concentration, coupled with the speed of the car is too fast to react to lead to secondary accidents.
In addition, if the vehicle breaks down in a climate environment with poor visibility such as rain or snow, or a problem causes a problem to be forced to stop, it is also recommended that you wear a reflective vest when dealing with accidents and checking the condition of the vehicle. The reason is the same, the sight of rain and snow weather is poor, and the rear car May not be able to operate when it finds you, resulting in a safety accident.
There is also a point that everyone must not ignore, where should the reflective vest be placed? Many friends may choose to put it in the luggage compartment, but in fact, this is not true. It should be noted that the reflective vest must be placed in the car.
When you buy a new car, you will find that the reflective vest that comes with the car is usually placed in the glove box in front of the co-pilot. This is also to facilitate the driver to find and wear a reflective vest before getting off the car, and when getting off the car, the car can be found at the first time, wearing a reflective vest to place triangular warning signs, check the condition of the vehicle and deal with accidents.
How to use jacks and fire extinguishers correctly?
Just above we introduced the use of triangle warning signs and reflective vests and precautions, and then we will introduce the use of jacks and fire extinguishers and precautions.
The vast majority of the models we can buy now are equipped with automotive folding jacks. The advantage of the folding jack is that it is light in weight, easy to store, and the production cost is relatively low, which is currently the most used by car companies. Due to its space-saving nature, this jack needs to be unfolded before use.
After installing the jack's handle in the specified position (some models use an integrated rocker, no need to install it), turn the handle to open the jack from the folded state to the ready state. The jack has an axis-attached bayonet above and a movable base below for easy use on uneven or sloped ground.
We need to pay attention to the fact that many friends will mistakenly snap the snap above the jack on the skin welding edge of the vehicle shell to support the vehicle, in fact, such an operation is not only wrong, but also very dangerous! Perhaps the welding part of the skin of some models is very hard and can support the weight of half the body, but in the process of removing the tire, the edge of the skin is difficult to resist the gravity of a point of shaking, not only easy to break the edge of the skin, but also may lead to vehicle damage and unnecessary casualties.
The correct way of operation is to place the jack in the fulcrum position indicated by the vehicle, if there is no obvious indication, we can also support the jack near the side of the removed tire under the frame, turn the jack rocker at a uniform speed, use the small bevel gear to drive the large bevel gear to save effort, and gradually support the vehicle.
When releasing the jack, we should also pay attention to it, I see that many friends on the Internet are directly "violently" removing the jack after replacing the new tire, such an operation is also very dangerous. Not only is it easy to deform the fulcrum point suddenly, but it is also easy to be injured by the popping handle. The correct way is to turn back to the shake handle, slowly lower the jack, clean up the dust and gravel on the jack gear and put away the jack, which is the safe operation process.
We have just introduced the use of jacks, and then we will talk about fire extinguishers that are not used often. The most important thing about a fire extinguisher is not how to use it, but to make sure that it is still valid. The air pressure in the body of the expired fire extinguisher tank will be reduced, such as our common vehicle-mounted dry powder fire extinguisher, and the powder in the tank may be damp and clumped after the shelf life, which will seriously affect the fire extinguishing effect.
In addition to ensuring that the fire extinguisher is valid for a long time, we also need to learn how to use the fire extinguisher. In fact, for everyone, the use of fire extinguishers is not difficult.
The first step pulls open the safety pin, the second step points the spout at the flame, and the third step presses the rear handle for easy use. However, it is worth noting that if it is a headwind, we must not use a fire extinguisher without rubber tubes to extinguish the fire, so it is likely that the powder will blow to themselves because of the wind, and if the dry powder enters the eyes, there will be burning, tears and even temporary blindness. In this way, not only did it not succeed in extinguishing the fire, but it even "killed eight hundred enemies and inflicted a thousand self-inflicted losses."
The on-board fire extinguisher is small in size, the capacity is not large, and the continuous spraying time will not exceed one minute at most. So if there is a fire in the car, the tail box, etc., we must aim the flame at the spray. However, if there is a fire in the cabin, we must pay attention not to open the hatch cover hastily, and if you can, you should use a damp cloth to open a gap to extinguish the fire.
If you find that the fire is reduced, you can open it and continue to spray. But if the fire does not decrease, it should still wait for professional firefighters to deal with it. After all, money is something outside the body, and life safety is the most important.
How to remove the anti-theft screws?
Finally, we want to introduce to you a cold knowledge that is not often encountered nowadays, that is, when dismounting tires, what should I do if I encounter a "different looking" bolt? In fact, you don't need to worry, this strange-looking bolt is actually an anti-theft screw. Anti-theft screws are generally used in European brand models, and today the Imported Models of audi brands and Volkswagen brands are still equipped with anti-theft screws. Of course, it can also be seen from the side that The social security in Europe is indeed worrying. Back to the point, how to disassemble the anti-theft bolts? Let's look down.
In fact, the significance of the anti-theft screw is nothing more than to let the thief steal the tire in a short period of time without sufficient preparation, and the universal wrench alone. But if you, as the owner, don't know how to disassemble it, it's a big deal. In fact, removing the anti-theft screw is very simple. Simply go to the partition under the trunk floor where the spare tire is placed to find a transfer screw, which is usually placed with a jack and a wrench.
The adapter is not very large and unremarkable, and it is very simple to use. Mount the adapter directly on the screw of the wrench and rotate the anti-theft screw counterclockwise to remove it. It should be noted that the anti-theft screw is generally only one on each wheel, so everyone must put it back in place after using the rotary interface to avoid loss.
If you change the tire in the repair shop should also pay special attention, be sure to instruct the maintenance master, do not violently disassemble the anti-theft screw, because the anti-theft screw is generally used is the internal and external flower of the imperial bolt, the imperial six-flower bolt pattern is more precise than the ordinary hexagonal bolt, violent disassembly may lead to the buckle. And once a buckle occurs, it is difficult to remove the bolt.
In fact, in addition to the anti-theft screw can play a role in preventing tire theft, there is another small device to prevent tire theft. It looks like a decorative cover for the rim designed to block the exposed bolts, but its main function is to prevent tire theft.
Such a design is widely used in Audi, Bentley and other models, how to remove the anti-theft decorative cover? Of course, it is also necessary to open it with a small device. We also have to go to the luggage compartment, open the cover under the spare tire slot, you can see the jack, wrench and other accompanying tools. A small crochet device can be seen in the corner.
Use the crochet needle inserted into the small round hole in the middle of the decorative cover and pull the crochet outward to open the decorative hood to expose the bolts. In general, because the decorative cover has the same function as the anti-theft screw, it is rare to have two anti-theft structures. After reading the above operation techniques, no matter what kind of structure you encounter, you can easily deal with it.
