In the field of building construction and other work at height, safety has always been a concern. With the development of science and technology and people's increasing attention to safety, the safety control of aerial work has become a very important topic. This article will focus on the key points and practical strategies of safety control of work at height from the aspects of definition, classification and basic safety requirements of work at height.
First, we need to understand the definition of working at height. According to the national standards, high-altitude operations refer to operations that are carried out at heights where there is a possibility of falling at a height of more than 2m (including 2m) on the datum of the falling height. This means that as long as the operator may be at risk of falling while carrying out the work, it falls under the category of working at height. Therefore, in practice, we need to carry out strict safety control for all possible work at height.
Secondly, the classification of work at height is for better safety control. According to the national standards, there are four levels of construction work at height:
1.Level 1 high-altitude operation: when the height of high-altitude operation is 2 5m, its fall radius is 2m.
2.Level 2 high-altitude operation: when the height of high-altitude operation is 5 15m, its fall radius is 3m.
3.* Working at height: When the height of working at height is 15 30m, its fall radius is 4m.
4.Level 4 high-altitude operation: when the height of high-altitude operation is greater than 30m, its fall radius is 5m.
By grading work at height, we can better formulate corresponding safety measures for different levels of work at height to ensure the safety of workers.
Next, let's take a look at the basic safety requirements for working at height. In order to ensure the life safety of personnel engaged in high-altitude operations, the construction unit shall provide qualified safety helmets, safety belts, non-slip shoes and other necessary personal safety protective equipment and supplies for personnel engaged in high-altitude operations. Personnel engaged in high-altitude operations should wear and use these safety protective equipment and supplies correctly according to regulations.
In addition to personal safety protective equipment and supplies, we also need to pay attention to the following points:
1.Strengthen the training and education of personnel engaged in high-altitude operations, and improve their safety awareness and self-protection ability.
2.Formulate detailed operating procedures for working at height to ensure that operators operate in accordance with the prescribed procedures.
3.Strengthen the supervision and management of high-altitude work sites to ensure the safety and order of the construction site.
4.For special high-altitude work projects, such as high-altitude hoisting, high-altitude welding, etc., special safety measures and emergency plans need to be formulated.
In short, the safety control of aerial work is a systematic project, which requires us to consider and implement it comprehensively from many aspects. By strengthening the understanding and mastery of the definition, classification and basic safety requirements of work at height, we can better protect the life safety of personnel engaged in work at height and reduce the probability of safety accidents. At the same time, we also need to continuously sum up experience, improve the system, and continuously improve the safety management level of aerial work, so as to contribute to the safety development of construction and other aerial work fields.
