Investigation of the Safety Conditions of Voltage in High Voltage Network Poles: A Case Study of Benin City, Nigeria

Abstract

This study focused on the investigation of the safety condition of

voltage in high voltage network pole. The study involved the use

of 132KV transmission line and the safety level during which it

operates under certain power condition. The interview conducted

showed that when the power is on or in a stressful condition,

there is high potential hazard which puts workers' safety at risk;

hence hazard identification is essential at every stage of the

process. The goal of this study is to identify the sources of

potential workplace risks based on the four impacted

classifications: the general public, work-related technical staff,

installations, and the environment. The interview conducted

revealed the potential hazards for the general public safety and

the control measures required. The preliminary findings of this

study indicate that falling objects, flash over, injured workers,

scorching temperatures, improperly built aluminum and

bulkhead ladders, and the existence of stressful conditions on

each conductor are the sources of hazard when operating at 132

KV voltage. Hence, for the implementation of work in a 132 KV

voltage state, it is recommended that every technician follow the

SOP (Standard Operating Procedure), wear complete Personal

Protective Equipment (PPE), and be cautious when doing work

and socializing with the surrounding community.
