In the field of mountaineering, various equipment is used. One of them is the safety system, which is worn on the person to ensure safety. A rope is attached to it with the help of a carbine or a knot - "figure eight". The equipment is designed to distribute the force when pulling the rope due to falling and to protect against injury. Safety systems must comply with ULAA.
Types of systems
The safety system can be of several types: chest harness, arbor, combined. The main details of each are:
All elements must be of high quality, because the reliability of the design depends on them. Equipment is selected depending on the sport.
Self insurance
This concept implies a device used for climbing insurance in difficult mountainous areas. The mechanism must be free from damage and destruction. Its main task is to withstand the greatest jerk.
The safety system is manufactured using the production method. Equipment must be checked. There is a certificate for quality products.
The use of a self-insurance mustache is allowed only after training by an instructor. The safety-holding system in this case is a small piece of rope or a sling with loops at the ends.
What is insurance required for?
Works are high-altitude if the distance between a person and the earth is more than 1 meter. For their implementation, a safety system is required. The mechanism is needed to work in conditions of risk of falling from a height. Its purpose is to protect against injury and to provide a better landing.
Human safety depends on the proper operation of all parts of the equipment, as well as on the selection of a suitable protection system. You need to learn how to use it correctly, since each mechanism is different in application. This requires practice, and only after it will be possible to work at height.
"Lower harness"
This individual safety system is attached to the belt and upper thighs. The design is universal. It is used for extreme activity. There are several options for these systems. Many of them adjust the waist and leg girth thanks to special buckles.
The advantages of this option include ease of use, lightness, compactness. To ensure complete safety, you must learn to use the equipment correctly.
"Upper system"
Such fall protection systems are worn on a torso. They are an addition to the lower system if the sport or work will be very dangerous. Equipment increases safety. The system is needed for the convenience of placing special equipment. It can be used separately only with experience.
“Combined system”
Equipment includes the functions of both previous systems. It is used where reliable protection is required - in difficult mountaineering, caving, industrial mountaineering and other extreme types of activity. The advantage is ease of use, moreover, this tool is less bulky.
The combined system has maximum security. It can be used for children. But it is more difficult to remove and put on in comparison with other types of equipment.
Selection tips
When choosing a system, the scope of its use must be taken into account. If it is difficult to determine, then you need to purchase a universal model. It is important to consider size. There are designs made on the principle of "one size". There are products that are divided into several sizes - S, M, XL. You must choose the right size, because only it will provide the appropriate security.
The systems are adjusted with special buckles necessary for high loads. Nowadays, products with ordinary single buckles are practically not sold, but often in stores you can find “double lock” - double buckles, with the help of which adjustment is facilitated. It is better to purchase equipment with unloading loops.
Do not buy new, unverified designs. You need to get a reliable thing. Before prolonged use, it is advisable to check the design. It is best to buy products from trusted brands.
You need to be careful about the choice of equipment. It is necessary to learn its use, best of all - from professionals. You should consult with experienced people, instructors. Only after practice can you engage in extreme sports.
For safety systems to last for a long time, they need proper care. They are washed with laundry soap and cleaned of sand and dirt. It should not be dried under the sun and on the battery. The period of operation is usually 1-3 years, but it all depends on the intensity of the loads. Before use, check the system for damage. Home-made systems should not be used, since production systems will be the best for safety.
