It deals principally with risks to health and safety rather than damage to services. However, precautions taken which reduce risks to people’s health and safety will generally also reduce the risk of damage to services, which can directly or indirectly pose a risk to people’s health and safety.
workplace. Working with electricity in any environment can be highly dangerous but particularly so on a construction site where the hazards have the potential to be on a much biggerscale. Its often a lack of awareness that causes the most damage so it’s essential that anyone required to work on a construction site understands the risks and knows how to act to avoid themselves, or anyone else, coming to harm as a result of electricity. This paper describes the basic fundamental of OH transmission lines and UG cables that cause electric shocks, electrocutions etc and their prevention with safety precautions in construction sites.

There are several hazards in the construction site while working the employee may undergo many risks, injury or accident. The focus on protection of the electrical worker was developing the safe work practices on the transmission lines. In transmission generally two types of transmission lines are there Overhead lines (OH lines) and Underground Cables (UG cables). In construction site these two transmission lines cause several hazards, before working on these transmission lines we have to plan the work and some guidance are provide in this paper to understand before gone to the work. Every year people at work are killed or seriously injured when they come into contact with live overhead electricity power lines. If a machine, scaffold tube, ladder, or even a jet of water touches or gets too close to an overhead wire, then electricity will be conducted to earth. This can cause a fire or explosion and electric shock and burn injuries to anyone touching the machine or equipment. An overhead wire does not need to be touched to cause serious injury or death as electricity can jump, or arc, across small gaps. One of the biggest problems is that people simply do not notice overhead lines when they are tired, rushing or cutting corners. They can be difficult to spot, e.g. in foggy or dull conditions, when they blend into the surroundings at the edge of woodland, or when they are running parallel to, or under, other lines. Always assume that a power line is live unless and until the owner of the line has confirmed that it is dead. This guidance is for people who may be planning to work near overhead lines where there is a risk of contact with the wires, and

The tabulated figures delineated in Table 1 [2] divulge the incidence of inadvertent fatalities brought on by electrocution in the years 2019 and 2020. The aforementioned data explicitly indicates a rise of 0.1% in the number of unintended deaths due to electrocution in the preceding year.

In Table 2 [2], we can discern the grievous impact of electricity by examining the number of persons injured versus the number of persons who perished due to electrocution in India during the year 2020. However, itis important to note that minor injuries resulting from electrocution are not included in the report as they are not reported anywhere. Furthermore, the number of male fatalities due to electrocution is significantly higher than that of their female counterparts. This is a result of the male- dominated workforce that exists in industrial and other sectors. When evaluating electrical safety, it is imperative to refer to various standards such as the National Building
