Safety lanyard: types and applications

Working at height is an integral part of many professions. This type of activity implies strict adherence to safety rules and the mandatory use of safety devices that will help avoid injuries and deaths. Manufacturers produce a wide range of lanyards that differ in price range and design. Before starting to use this device, be sure to carefully study its features and area of ​​use.

A safety sling is a special device for working at height, the task of which is to prevent workers from falling off and falling from a height. This element connects the high-rise belt to the support structure or other fixing devices.

Scope of the fall arrest device:

• restoration work;
• repairs at height;
• construction and installation work;
• extreme and sports sports.

The safety element has the following functional load:

• positional - for construction, installation, repair and restoration work at height;
• belay - ensuring safety when moving;
• softening - reducing the dynamic impact in the event of a breakdown and fall.

Taking into account the wide field of application of safety slings and different purposes, manufacturers produce the following types of devices.

• Safety - for positioning in the work area to prevent falls. Scope of application - work at an altitude of no more than 100 m.
• Adjustable shock absorber - for belaying at a height of more than 2 m. Design features of a simple element with a shock absorber - the presence of seams on the synthetic tape with different thicknesses of the thread, which break when falling, except for the last one.

Also, the sling can be single or double, with a length regulator and with a different number of carabiners. The following materials can be used as basic raw materials:

• synthetic rope;
• wicker textiles;
• nylon tape;
• steel chains;
• cables.

Depending on the type of rope used, the products can be of the following types:

• wicker;
• twisted;
• twisted with steel inserts.

A feature of rope and tape slings is the presence of a protective metal or plastic thimble.

Also, models can be single-arm, double-arm and multi-arm. The two-shoulder safety sling is the most popular and demanded one.

Before starting to operate the device, it is necessary to carefully study the operation manual, and the design of the safety devices must necessarily correspond to the scope of application. If the height does not exceed 100 cm, then experts recommend using positioning and holding elements; at a higher level, it is better to use belay devices with shock absorbers. The main condition is that the length of the product should not exceed the height of the working area.

Work in high temperature conditions is best done with metal belts. Despite their reliability, their use is not possible when working with electrical installations. In contact with alkalis, it is better to use products made of nylon tapes, and acidic surfaces do not come into contact with lavsan insurance. Also, the following factors influence the choice:

• the level of resistance to unfavorable working conditions and aggressive environments;
• temperature Range;
• level of resistance to mechanical damage.

When operating the safety elements, the following sequence of actions must be observed:

• visual inspection of lines with possible detection of defects and damages;
• checking textile parts for flexibility;
• checking the thimble, seams, anchor loops, joints and ends of the product.

In case of revealing even minimal mechanical, thermal and chemical damage, it is strictly forbidden to use these products. Ignoring this requirement can lead to irreparable consequences. Also, you can not use those slings that have lost their elasticity, even in small areas.

It is unacceptable to use the product with stretched, twisted or damaged seams. Do not carry out self-repair or alteration of the structure. If an adjustable bracket is present, then it is imperative to check its serviceability, and also make sure there are no rust or cracks. Only after making sure that the device is in perfect working order can it be put into operation, and deformed devices must be destroyed.

Labor protection specialists recommend that you pay attention to the fact that safety slings are subject to annual revision with the subsequent entry of information into the registration card. Products that have not passed the mandatory technical inspection are also removed from service. The operating time of the slings is directly influenced by the storage conditions.

Before the safety slings are sent for long-term storage, they must be cleaned of dirt and thoroughly dried. Joint storage of devices with flammable chemical compounds is inadmissible. During storage, it is imperative to regularly lubricate the metal elements.

Working in areas of increased complexity requires special attention and the most accurate observance of safety rules, especially when it comes to high-altitude work... To minimize the risks of injury, as well as preserve the life and health of employees, it is necessary to use safety slings. Manufacturers produce a wide range of these products, the correct choice of which depends on the scope and working conditions. Before using the slings, you must carefully study the instruction manual and strictly follow all the recommendations.
