Development of Electrical Hazard and Probability (ELHAP) Tool Related to Equipment and System Failure

Electrical safety in the industrial process plant plays an important role to ensure
overall safety of the chemical plant, but most of the time this subject has been largely
ignored leading to major accidents in the plant. Due to this reason, many researchers
find that it is important to understand completely the electrical system to avoid any
accident in the plant. Hazard and Operability (HAZOP) analysis tool is widely used
as qualitative tool to identify potential hazards that can cause major accidents in the
plant, while the Fault Tree Analysis (FTA) method is widely used to estimate the
probability of occurrences of the hazards. However, they have never been
implemented vigorously to identify potential hazards due to electrical equipment and
system failure. Thus, the main objective of this project is to provide a framework for
systematic investigation of the problems in process plant due to electrical equipment
and system failure. This project consists of analysis that is done to complement the
need for detailed study of the electrical hazard. The analysis will include both
qualitative HAZOP analysis approach to identify the possible hazards and a
quantitative FTA assessment to rank the hazardous event accordingly for direct
implementation in industrial case study. The tools developed will provide a detail
review of chemical plant safety focusing on electrical equipments and system design.
At the end of the study, the analysis will help to provide suggestion to improve the
design, installation, operation and maintenance procedures in order to optimize the
safety and operability in the plant.
