Abstract:
Electricity distribution is a vast sector and it is stretched out over the whole country. Huge
quantity of distribution line, line equipment, workers and public are involved in the system.
The activities of the distribution system are mainly risky. The possibility of safety breaks in
this system is very much for it's complex and risks involved operation. Death due to
electrical shock is as usual news published in most of the Daily Newspapers.
For a country like Bangladesh due to economical and technological drawbacks and lack of
giving proper importance of the sector, I lie management of distribution system in
Bangladesh is still using very primitive methods with minimum or without using of personal
protective devices (PPE) for completion of' distribution system activities. Non availability of
safety measures posses a great challenge to the workers enhancing the uncertainties and
risks, resulting injury and accident. In this research, it is tried to explore the occupational
safety problems t hat exist in distribution system in Bangladesh. It is also investigated, the
possible hazards available in distribution system and tried to find out the main causes and
agents responsible for accidents.
Keeping this view in mind, data for this project were collected from distribution systems as
primary data through a prescribed questionnaire. 'Three sets of questionnaires were prepared;
one for distribution system workers, one for managers and the another for public. Six
distribution organizations were taken into consideration for data collection. During study,
different categories of distribution system workers, managers and public were interviewed
based on the level of technical knowledge, experience, intimacy with the accidents and also
educational level. The sample was kept relevant considering the time and cost. Victim,
witness, experienced workers and managers were included in the sample. The sample size
was limited to 1 55 for distribution system workers, 20 for Managers and 175 for public. The
different categories of workers were regrouped into tour categories for the study purpose,
such as High- skilled, Skilled, Semi- skilled and Un -skilled. 19% 1-1gh-Skilled, 36%
Skilled, 20% Semi-Skilled and 161X) tin-Skilled workers were selected as sample to reflect
the staffing pattern of it distribution system (Appendix-A). About 91 of workers
Experienced with accident during their work in distribution system. Personal negligence,
lack of experience, not to use PPE, absence of good working environment, over confidence
and finally excessive work loads were also identified unanimously by workers as causes of
accident. Most of the managers were agree with the causes mentioned by workers. Both the
managers and workers mentioned that illegal use of electricity, tree adjacent to distribution
line, improper clearance of line is the main causes of accident for public.
To prevent accident (in case of workers) 30.76% managers suggested to use PPE followed
by 21. 15% suggested for continuous supervision, 1 7.3% for raising awareness, 13.46% for
training, 9.6 % for ensure good work environment on distribution system works and 7.6%
recommended fur justified work load. For public safety, both the workers and mangers
provided some suggestion as- improving public awareness, operation to remove illegal
connection and discourage public to plant trees near distribution line. As far as knowledge of
rules and regulations is concerned about 7% workers know about Electricity Acts-i 910. But
most of them do not have any idea about departments responsible for looking after the
Electricity Acts-I 910. Moreover, the government workers right and occupational safety & health
issues along with the working environment of distribution organization and surroundings
were not active at all.
At last, some recommendations are made for the betterment of distribution sector. The
proper application of the recommendations will be helpful to reduce the frequency of
accidents and there by will be possible a sound operation of the distribution organizations as a whole.
