Ensuring safety during work at height is the most important task in the context of the development of a modern construction complex. Falling from a height occupies one of the first places in terms of the number of victims among all the traumatic factors, based on the statistical data, and its share among other traumatic factors is 28 %. Works at height include construction works, in which there are risks associated with a possible fall of an employee from the height of more than 1.8 m. The employer is obliged to ensure the implementation of measures to reduce injuries at the construction site in accordance with the current legislation. Protective measures when working at height include personal and collective protective equipment, including the use of anchor lines on the building roofs.
The article provides for a comparative analysis of five options for the installation of anchor lines suitable for wooden, concrete, metal, and green roofs.
For the analysis, a flexible anchor line using a metal cable, a rigid anchor line on high supports, a rigid anchor line on low supports, a flexible anchor line with weights for use on the roofs with landscaping and a flexible anchor line with supports were selected. All the selected anchor line systems comply with the international safety requirements and can be used by one or more workers.
The advantages of each system of the anchor lines are revealed, a wide variety of roofing materials are considered: metal seam, made of polyvinyl chloride, with oriented strand board and thermoplastic polyolefin reinforced membrane, which is a high-tech polymer roofing material.
All the anchor lines have a variability in terms of the shape and can be used on the roofs of any configurations in the building design without additional efforts and search for the complex solutions on the part of the designer.
