Work at height is carried out in various industries and areas of human activity: from construction to science and entertainment. But despite the variety of tasks and conditions, there are a number of general methods for ensuring safety when working at height.

Safety systems for working at height can be divided into several types:

• restraint systems;
• safety systems;
• positioning systems;
• rope access systems;
• evacuation and rescue systems.

The choice of the system or systems used is made based on the task at hand, the configuration of building structures, the architecture of the building, available supports for installing anchor devices, duration of work, etc.

Restraint systems

Restraint systems limit the area of ​​free movement of the worker, preventing him from being at risk of falling. If the restraint system is used correctly, the worker simply physically cannot fall over the height difference.

Compound:

• holding lanyard or traction rope, carabiners (connecting and shock-absorbing subsystem);
• restraint or safety harness.

Restraint systems do not place large loads on the worker's body, so both a safety harness and a restraint and positioning harness can be used. The worker's harness is connected to the anchor device using a restraint or safety lanyard. It is allowed to use slings with a length adjustment device. Petzl JANE and Petzl GRILLON slings are suitable for organizing restraint systems.

To expand the area of ​​possible movement of a worker, flexible or rigid horizontal anchor lines can be used. In this case, the worker will move along the anchor line.

It must be understood that the restraint system is not, in principle, designed to stop a fall, but only to prevent it. Therefore, in the area of ​​possible movement of the employee there should be no unstable surfaces, openings, open hatches, etc. There may also be a risk of falling when approaching the corners of buildings.

Unacceptable use of restraint systems

Safety systems

Safety systems should be used whenever there is a risk of a worker falling. Their purpose is not just to stop a fall (asphalt can do this too), but to do it safely. The dynamic load on a worker when stopping a fall—the braking force—should not exceed the safe value of 6 kN.

When using safety systems, it must be used safety harness. Fall arrest devices must be attached to the employee's harness at attachment points located on the chest or back, marked with the letter A.

Safety systems usually use shock absorbers that absorb some of the energy during a fall and reduce the braking force to a safe 6 kN. When activated, the shock absorbers extend. It is necessary to take into account the extension of the shock absorber when calculating the amount of free space under the worker. If there is insufficient headroom, the worker may hit the floor or other obstacles before coming to a complete stop.

Let's consider existing ways of organizing safety systems.

Safety system using a safety lanyard

Compound:

• anchor device, horizontal anchor line;
• safety lanyard with shock absorber, carabiners (connecting and shock-absorbing subsystem);
• safety harness.

The worker's harness is connected to the anchor device or horizontal anchor line using a safety lanyard. The lanyard must be equipped with a shock absorber, which reduces the force of the dynamic impact on the worker in the event of a fall. Using a double-legged safety lanyard, you can move in space while maintaining a constant connection to the support.

Application of horizontal anchor line

Belay system using a slider type belay device

Compound:

• anchor device, vertical or inclined anchor line;
• slider-type safety device, shock absorber (connecting and shock-absorbing subsystem);
• safety harness.

A safety device (for example, Petzl ASAP) moves freely along the anchor line following the movement of the worker, but if the worker falls, it is automatically fixed and stops the fall. Safety systems using slider-type PPE and vertical anchor lines are used during roofing work, when climbing stairs to a support, and when working on inclined surfaces.

Use of a belay device on inclined and vertical anchor lines

Safety system using retractable PPE

Compound:

• anchor device;
• Retractable PPE;
• safety harness.

PPE of the retracting type is attached to the support, and the cable or sling coming out of it is attached to the worker’s harness. When a worker moves, the cable is automatically extended from the block or retracted into it depending on the direction of movement. In the event of a fall, the automatic braking system stops the fall. Some retracting-type PPE models provide a smooth descent system to lower the worker to the ground at a safe speed.

Positioning systems

Compound:

• anchor device;
• lanyard for positioning, carabiners (connecting and shock-absorbing subsystem);
• harness for holding and positioning.

Positioning systems are used to fix the worker at height and provide support for work, while minimizing the risk of falling below the support point by adopting a certain working posture for the worker. Such systems are used when a worker has support under his feet, but to maintain a stable position requires holding on with his hands. A striking example is work on towers and cellular masts. The positioning system allows you to free your hands for work.

The use of a positioning system requires a mandatory safety system.

For positioning, slings of adjustable and fixed length are used.

The positioning lanyard can be attached to the support in a circumference, or using an anchor device.

Positioning a worker using a Petzl GRILLON sling,
the safety system is represented by a flexible anchor line and a Petzl ASAP belay device

Rope access systems

Rope access systems allow you to reach the work site by ascending or descending along a rope - a flexible vertical or inclined anchor line. Such systems are a last resort solution when other access methods such as scaffolding, cradles or lifting towers are not practical.

To lift and lower a worker along vertical (more than 70º to the horizon) and inclined (more than 30º to the horizon) planes, as well as to perform work while suspended in an unsupported space, a rope access system is used, consisting of anchor devices and a connecting subsystem (flexible or rigid anchor line, slings, ropes, carabiners, descending device, lifting device).

Work using rope access systems is carried out with the mandatory use of a safety system, consisting of an anchor device, a connecting subsystem (flexible or rigid anchor line, shock absorber, slings, ropes, carabiners, catcher, safety harness).

It is not permitted to use the same rope simultaneously for the fall arrest system and the rope access system.

Rope access systems use a harness combined with a sitting harness. Fall arrest devices are attached to the thoracic or dorsal attachment point, marked with the letter A. Lifting devices (clamps) and lowering devices are attached to the attachment point located in the abdomen.

When working in a suspended state for a long time, it is necessary to use a work seat to prevent circulatory problems.

Evacuation and rescue systems

Before carrying out any work at height, an evacuation plan should be developed in the event of a hazard. The evacuation plan must ensure that the victim is brought to the ground within 10 minutes to prevent suspension injury. In the absence of a simple, quick and safe escape route, personal rescue devices can be used to allow the worker to independently descend from a height.

A rescue plan must also be developed in the event that an employee falls and hangs on the safety system, or if it is impossible to independently descend from a height due to injury or poor health. For this purpose they are used rescue kits, which may include anchor devices, ropes, descending devices, special winches, pulley systems (for example, Petzl JAG RESCUE KIT).

Petzl JAG RESCUE KIT

Very effective pre-installed rescue systems- in this case, devices for descent are pre-built into the safety system or rope access system in such a way that, if necessary, the worker can be evacuated at any time. The anchor lines are secured using lowering devices, and their length is selected with such a margin that it is enough to lower the worker to the ground. This method requires a longer anchor line, but in the event of an accident, it allows the worker to be lowered in a matter of minutes. Evacuation can be carried out from a safe place, without climbing to a workplace at height.

A safety harness is one of the elements of the system that ensures safety and protects against a fall. We will tell you about its design, testing and GOST requirements.

Read in the article:

Safety harness (webbing safety belt for high-altitude work)

According to the current state standards in our country, work that is carried out more than 1.8 meters above the ground is considered high-rise. Of course, such work cannot be done without special tools, so individual safety devices have constantly evolved: from primitive crampons and hooks to mounting belts and complex safety harnesses for working at height (hereinafter SP).

A safety harness is an important element of a safety system used during high-altitude work, reliably holding a person at a given distance from the surface and preventing a fall. It differs from others in its reliable coverage, as well as fixing the body in a comfortable, safe position. These capabilities are provided by a well-thought-out system of shoulder and hip straps, durable slings, adjustable straps, and self-locking buckles.

When used correctly, this design does not restrict the movements of the climber and does not allow him to slip out of the safety system, no matter how he is positioned during work. This, however, does not mean that anyone without training can use it. A high-altitude specialist is obliged to comply with all labor safety requirements, properly check and use his joint venture.

Briefly, the general test rules look like this:

• Before each use, the joint venture must be carefully inspected for damage or loose components;
• when putting it on, you need to make sure that the belt is at the waist, the leg and shoulder straps are in their places;
• the back point should be adjusted, the shoulder straps should be tightened;
• Next, the shoulder straps need to be connected to the belt using buckles and carabiners.

After this, you can test the strength, observing the conditions established by the manufacturer, that is, in the recommended temperature conditions, away from chemically active substances and sharp objects. The product is tested for static and dynamic loads on special stands using a steel dummy that imitates a person.

SP storage is carried out according to the rules: in a dry room, protected from direct sunlight. Do not store equipment near heating devices, flammable or chemically aggressive substances. After cleaning, only natural drying of the product is possible.

It is important to remember that if the structure is damaged or weakened in any way, the harness cannot be used, and after the warranty period has expired, the equipment should be taken out of service and destroyed.

Testing safety belts according to new rules

Similar standards apply to the operation and storage of mounting belts, but the test details differ. Once every 6 months, belts must be tested for a static load of 4,000 N.

This is done in two ways:

• the belt for working at height is fastened with a buckle on a rigid cylindrical beam, and a load giving a load of 4,000 N is suspended from the ring on the waist belt for 5 minutes;
• After securing the belt to the beam, the ring on the waist safety belt is attached to the winch, which develops a load of 4,000 N for 5 minutes.

The slings are tested in a similar way, suspending loads of 4,000 N for 5 minutes with a carabiner attached to the anchor.

If after testing the metal parts are not deformed, the fabrics and threads are not torn, or other defects appear, then the test of the safety belt is considered successfully completed.
