Risk Assessment for Working on Overhead-Underground Services

1. The Scope

The information that is described and discussed in this guideline document will be helpful and beneficial for you if you are as project electrical engineer, a project in charge, or you are a maintenance supervisor, electrical technician and or occupational health and safety professional. This document contains some pithy but very important, informative and useful key points related to the overhead or underground services e.g., high voltage electrical transmission lines, electrical cables, and or underground oil, gas, electrical or water pipelines. To accomplish such services, underground trenches, excavations, etc. have to make and the possibility of fatal and severe electrical, suffocation, or hit by or ruined by the heavy machinery is severe. 

2. Introduction

The maintenance and installation services always involve the possibility of high ratio risks of human injuries, financial or legal complexities in the shape of the hit by the other existing underground services. Moreover, if this type of operations is not planned, organized or monitored or reviewed properly by the relative professionals including project engineers, line managers, supervision and other workforce are not competitive or not trained as per the required standards and standard operation procedures specific to that activity, the possibility of high-risk incidents or ill health issues will severe.

3. Health and Safety Consequences

During the installation and maintenance of the underground or overhead objects, the possibility of severe damage to underground installations notable. If it is being carried out by heavy equipment or machinery (cranes, shovels, etc.) the pipelines or gas or water installations also hit by the machinery. Risk of electrical injuries, skin burns, or electrical arc is also very much.
Sometimes, in deserts like geographical locations, the collapse of trenches, burying of human in excavations is very high.

4. Legal or Statutory Obligations

In each state and country, some health and safety legal or statutory and welfare rules, regulations, technical guidelines, and standards operating procedures. As employer or employees, if we are operating in the United States of America, we have to follow the OSHA standards, and if we are in the UK, we have a various health and safety compliance bodies, e.g., IOSH, etc.
And if as being a Health and safety practitioner or an organization, we are operating in the United Arab Emirates, we have to follow OSHAD Standard operating procedures, technical guidelines or other rules that are being followed by all seven states of UAE.

5. Safe System of Work (SSOW)

Annually, most severe and fatal injuries and ill health occurrences are recorded in the work activities related to overhead and underground excavations.  The question, how as being a project engineer or health and safety in charge, how we can reduce or minimize the possibility of risk of serious injuries and consequences.
We must strictly follow and implement some of the following key elements:
1.    Plan in advance
2.    Hire a competent workforce
3.    Get the authentic layout of the area of service and activities
4.    Appropriate use of electronic and metal detectors
5.    Safe operation practice of cable digging, drilling, excavations
6.    Appropriate health and safety training
7.    High level of supervision
8.    Continuous monitoring and review.
