description |
Gas supply contributes to major fuel requirements for petrochemical plants, power
generation, large and small industries to upkeep the operation and production to meet the
consumer’s demand. To achieve that, gas pipeline construction plays an important role to
provide the infrastructure for gas transportation through the pipelines to ensure
uninterruptible supply. Constructing a gas pipeline involves high-risk activities such as
excavation works, Horizontal Directional Drilling (HDD), lifting, confined space
activities, and welding works which are required to be performed along the construction
process. This activity requires serious attention for hazard identification associated with
the task, performing risk assessment, and implementation of control measures to
minimize the occurrence of occupational accidents. Hazard identification, Risk
Assessment, and Risk Control (HIRARC) is a fundamental tool that helps to minimize
and prevent accidents to take place in the workplace by cultivation a safe work system
through matrix analysis which reveals the likelihood and severity of accidental
occurrences. This study aims to perform hazard identification, conduct a risk assessment,
and propose control measures based on the hazard and risk associated with the gas
pipeline construction activities. Performing hazard identification based on the
construction activities leads to several findings which can be evaluated and improved to
prevent accidents. The evaluation and analysis are conducted based on the site
practicability, experienced personnel opinions, and previous lesson learned. Upon risk
assessment completion, a control measure is proposed according to worksite suitability.
This is achieved through adaptation of several methods such as survey analysis conducted
which consists of 127 respondent who is working in the gas pipeline-related construction
field, site observation on actual construction practice, Fault Tree Analysis (FTA), and
HIRARC form is used to identify the hazard and analyses the risk associated with the gas
pipeline construction activities. Findings show that the attitude of the workers and
responsibilities of the employee and management plays an important role in cultivating a
safe work system. Besides that, negligence in small flaws leads to critical accidents or
contributes to the main event which leads to a more severe impact. Moreover, this study
also demonstrated that the involvement of management focusing on safety aspects
improves the site safety practices. Safety competence personnel also ensures the worksite
safety through site inspection and induction briefing is carried out on daily basis.
Implementation of more comprehensive HIRARC through this study improves the site
safety practices through awareness to the construction personnel which emphasizes on
safety is everyone’s responsibility and working safely is the top priority. |
