Investigation was conducted in order to find the root cause of the accident.
However, the questions remain unanswered. Experts and investigator only found out
the gas explosion is caused by pipe leaking. Hence, experts and investigators listed
few reasons that cause the pipe leaking. The first cause of the tragedy is safety
regulations are not being observed due to the deadlines given by the manager is too
short. These lead to some firms on the site do not observe the danger zone designed to
prevent heavy machinery being placed over the pipelines. As the heavy machinery
placed above the pipelines, there are potential mechanical aggressions that may
weakened the pipe wall. Besides, heavy rain and large machinery will cause soil
erosion; this explained some pipes are not 1.1m beneath the surface [3].
In addition, the workers work is overload. Ten engineers are responsible for
checking 3706km of pipelines. The engineers may not have sufficient time as the
deadline given is too short. Therefore, some area is assumed to be safe and ignored by
engineer in order to meet the deadline given. The ignored area is where the accident
occurred. Furthermore, the workers of the company are not well train in dealing pipe
leaking experience. As natural gas has no smell and coulerless, workers must learn the
standard of procedure in order to identified pipe leaking and take action as soon as
possible to prevent tragedy happened.
