The primitive hunter, who managed to attach a stone to a stick, laid it in the foundation of eternal science - safety engineering. Losers who neglected it did not survive. But apparently not all. Descendants of nonchalant meet among us.
As the vehicle’s ground clearance was reduced, it was becoming more difficult to tighten the nuts under it, more and more it was necessary to work by lifting the car with a jack. And the ease of use and safety are only apparent. Having hung out the car, you should not immediately dive under it with the keys - it can be very painful to pinch, or even just flatten.
Most often, a jack is needed when changing a punctured wheel. It would seem that the operation is simple, but the machine happens to fall off the jack. Another "master" is trying to hold her by grabbing the threshold or arch. If you are not a weightlifter playing pancakes under a quarter ton - not worth it! All the same, do not hold it, and you will be fed with a spoon for a long time.
That is why it is so important that the machine lifted by the jack cannot move. You are too lazy to drive the stops under the wheels of the opposite side, relying on the handbrake and hard asphalt - this time it may be lucky, but one day the car will certainly crash! And on the ground, especially wet, - be sure, most likely will fall! It is unlikely that anyone in the trunk has a pair of branded wheel rests, sometimes you have to use improvised material. However, a cobblestone correctly driven under a wheel is a good alternative. The main thing is to securely pinch it between the tire and the road. And to do this before, and not after hanging the machine - Fig. one:

But what good is it from stopping if the jack breaks! Therefore, before changing the wheel we put a spare wheel under the threshold. Having removed the pierced, we put it here and only then put the spare wheel. If the car falls down, then the threshold will fall on the wheel. It's okay if, we repeat, you do not poke your hands between them. Then there will be something to rearrange the jack and try again.
If you need to climb under the car, and even in a deserted place, we will be ten times more alert! Good sciatica is able to “crush” no worse than the machine itself. Outsiders will still pull you out, but they will also need room for maneuver.
Somehow, my friend decided to do his Volga at the dacha. He alternately lifted both sides of the car with a jack and put several thick boards under the thresholds. And while he was looking for what to lay on the ground, the car quietly moved … and collapsed! Slippery boards and a damp lawn let down. Here you have the material at hand! By the way, adjustable traguses have long been on sale.
But suppose the car is raised securely. Can I take the keys? Do not hurry. If the work is long, and the weather is not hot and with the wind, then drafts walk from below, and in summer there are still hordes of small blood-sucking bastards. In addition, dried-up dirt is pouring directly onto the head from the bottom, so a suitable hat, clothes and safety glasses cut out of at least a plastic bottle will come in handy.

We hope that the keys that you are going to work with are in good working order - we are talking primarily about carob keys. A thawed key can suddenly “lick” on a nut! Not only is it difficult to unscrew it later, but if the key is broken, there’s a great chance to drive your hand into some piece of iron - it’s very painful! Therefore, we work in gloves, and we pull the key towards ourselves, and not from ourselves - the fingers will be more intact.
Sometimes the strength of one hand is small. Instead of grasping the key with two, it is better to increase the lever by putting on a key, for example, a suitable pipe.
A stone ax with a wooden handle is a thing of the past, but the problem of getting a hammer off a handle still lives on. A hammer flies, we note, at the most inopportune moment - at acceleration, and then - as lucky. Whether it flies to the floor, gets into a car or bangs on the fingers is a will, but according to Murphy’s law, the maximum possible harm will be done. Therefore, we constantly monitor the reliability of the striker landing, timely change the soaked handle and wedge correctly - Fig. 3:

A pair of hammer and chisel deserves special respect. Over time, the steel hammer uncovers the nape of the chisel so that the petals twist into the ram’s horn. The danger is that upon impact, these curls fly off at great speed. It gets into the eye - a serious injury is guaranteed. Therefore, the hardening is periodically removed on the sharpener, and we work in goggles.
By the way, a variety of protective devices are sold for working with chisels. If you don’t have the right fungus on hand, we’ll put a piece of rubber hose on the nape of the chisel or wrap it with several layers of tape, etc. four:

The car is full of all kinds of springs. The thicker the spring, the stronger it can fire. Particularly aggressive are those in the suspension. You should not take risks, squeezing them when replacing with folk wire clamps - for this, reliable couplers are sold! Even the modest spring of the rear shoes strives to tear your fingers with your hook! Here, and sometimes the glove is powerless - experience and common sense will help.
Technical fluids. It is unnecessary to remind you that you can not drink them. Antifreeze is poison. True, weaker than potassium cyanide. Sometimes, making sure that it is he who is dripping, you can try it on the tongue - lick and spit right there. Antifreeze is tasteless and sweet! Nevertheless, it is not worth tasting once again, because if it was he who was poured into the cooling system, water from the radiator will not flow.
An anti-freeze based on isopropyl alcohol thickens in frost and copes with the task no matter. And on ethyl - excise taxes! Non-freezing ones based on it are prohibitively expensive - who will buy? Meanwhile, the whole world uses methyl alcohol liquids. As you know, you can’t drink it: if you survive, you can go blind. Such an idea will not even wander into a Finnish or German head, but these frost-free bans have forbidden us at all - away from sin. However, throughout the winter, five-liter large bottles with bright blue liquid are traded along the roads!
Petrol. Even children with mopeds know how to pump a petrolman out of a truck’s tank: he put a hose in, sucked his mouth in, and abruptly ended down into a bucket. In order not to overwhelm, you need skill. Experience comes fairly quickly, however, if you intend to often resort to this method, train ahead on a water barrel. And do not be greedy - although a hose with a diameter of 3 cm pours quickly, it will very soon teach you to distinguish gasolines from taste.
