Меры безопасности при производстве работ на двускатных крышах

Abstract

The study is concerned with the security measures in case of works carried out on gable roofs. Maintenance and repair works of gable roofs are compulsory when any building is used. Different types of networks (power lines, telecommunications etc.) are located on roofs. Gable roof operations are always associated with a risk of falling down as such roofs have slopes. More than 25 percent of accidents during construction operations are connected to the risk of falling down. The facts of falling from a roof are also included into the statistics of Communications and Power industry. The available regulatory documents on labor protection and layout of roofs contain the requirements to safety but these requirements are too general. Specific safety requirements are to be determined at the stage when an engineering design project of a building (roof) is being prepared. It is explained by the fact that gable roofs have different forms and arrangement of engineering systems, thus each design is individual. But in reality it is difficult to make project decisions with respect to safety measures for such kinds of work. According to the legislation related to labor safety, in case of works at heights people are obliged to use full-body safety harness which ensures safety of their work. But the combination of engineering, economic and organizational problems in case of works on gable roofs does not always result in using full-body safety harness. Therefore there is a great risk of falling which results in a high rate of reportable injuries. As an engineering solution of the above-stated problems, it is offered to arrange anchor points or anchor lines to fix full-body safety harness at the stage of designing and constructing works.
