Abstract

This paper examines issues of safety of high-altitude works, using individual protection equipment to prevent falling from a height. In particular, the paper reviews personal protective equipment - shock absorber, its dynamic characteristics and related test methods to meet the requirements of Technical Regulations 019/2011 “Safety of Individual Protection Equipment”. The paper discusses the differences between the Russian and European standards for dynamic characteristic testing of shock absorbers, even as the former are harmonized texts of the latter, and the effect of such differences on protective performance of shock absorbers and ultimately on safety of works on heights. It have been shown that tests, conducted in accordance with the Russian regulative documents for dynamic performance of the shock absorbers, entail decreasing in safety usage of such type of IPE and increasing in injuries during falls from a height. It has been defined necessity to actualize the range of the testing system of shock absorbers, and to admit its larger value that will cause increase in protective properties of shock absorbers.

Highlights

Falling from heights certainly stands apart as a cause of accidents in the construction sector
After the Customs Union Technical Regulations No ТР ТС 019/2011 “Safety of Individual Protection Equipment” was enacted, all individual protection equipment (IPE) is to pass the mandatory certification procedure to meet the provisions of the said Technical Regulations [9,10,11]
One of the major components of any IPE is a shock absorber designed to absorb the kinetic energy generated when a person falls from height and to make the stop after falling softer [12,13,14]

Summary

Introduction

Falling from heights certainly stands apart as a cause of accidents in the construction sector. This cause of injuries accounts for 30 % of all grave and lethal statistics, and the ratio will top 35% if we examine fatalities [1,2,3,4,5,6,7,8]. To ensure safe operation on heights, use of individual protection equipment (IPE) to prevent falling from heights is an option. Methodologies that regulate tests of such IPE are set forth in GOST R ЕН 355. “Individual protection equipment to prevent falling from heights. Testing Methods» [15], and GOST R 12.4.206 – 99
