Повышение уровня электробезопасности на контактной сети за счет создания новых знаков безопасности труда

Abstract

The analysis of injuries in attendants of catenary units showed that there happen electrical injuries due to extension of the workplace and its area, especially in case of work at interlinkage of anchor sections of station and wayside lines of the catenary system. It was found that attendants not always know their way around in complicated operation environment, show ignorance of the catenary sectionalizing and factual performance place, this resulting in their electrical traumas. The electrical safety signs used on railway catenary systems were studied. A new safety sign which will inform workers about a hazardous factor was invented. It will provide better orientation in the operational process, reducing the risk of being injured and increasing the safety level. The work safety sign was suggested to be installed at interlinkage spots of anchor sections of wayside and station lines and at edges of catenary different sections. The most suitable safety sign variant was determined from three work safety signs using ranking of the variants by the least rank sum. The expert opinion consistency was proved through calculation of concordance coefficient. Using χ2 Pearson criterion it was found out that the expert opinion consistency in selecting the most suitable safety sign was nonrandom. Further lines of research for inventing new work safety signs on the catenary were identified.
