The effect of light and weather on textile personal protective equipment against falls from a height in the construction industr

Introduction. According to the information of the Ministry of Labour and Social Protection of the Russian Fede­ration, the most common type of accidents with injuries and fatalities at work is a fall at different heights. The analysis of such accidents for 2022 and 2023 by types of economic activity shows that the largest number of accidents with severe consequences occurs in construction.

Purpose of the work. To ensure the safety of people with the help of personal protective equipment (PPE) when performing work at a height in the construction industry.

Objectives. Analysis of scientific works devoted to the influence of light and weather on textile protective equipment. Analysis of the group of GOSTs regulating the certification of PPE against falling from a height for the presence of technical requirements and methods of testing textiles and paint coatings for the impact of light and weather, including solar radiation; problem statement and development of recommendations for further work in this direction.

Analytical part. The safety of application of textile personal protective equipment against falling from a height as one of the most widespread types of protection at the construction site, which are exposed to the impact of light and weather, is considered. The analysis of scientific and technical sources shows that exposure to light (especially ultraviolet), as well as the combined effects of light, temperature, humidity and other atmospheric conditions leads to the degradation of textile PPE. On the basis of the complex analysis carried out in the paper, the conclusion is made about the need for normative regulation of this area of textile PPE in the field of technical requirements and test methods, as well as the need for additional parameter-oriented research in this direction.

Conclusions. Published sources do not contain information on light and weather resistance of textile PPE. The analysis of published studies indicates the negative influence of atmospheric conditions on textile and poly­meric materials. The necessity of development of test methodology and balanced requirements to the material resistance to light and weather impact is determined, as the existing GOSTs in the field of PPE against falls from a height do not apply to these textile PPE and have functionally unoriented criteria for determining the negative impact of light and weather.
