The permit to work in relation with occupational accident at Petrochemical Plant

Abstract

Permit To Work is an official documents used as a means of communication, control and managing of work activities to prevent accident at the Petrochemical Plant. But in many cases the Permit To Work has failed in its roles to control work activities which causes the occupational accident in the plant. Because of that this study was conducted to assess the Permit To Work in occupational accident occurred in the Petrochemical Plant This study was conducted by distributing 260 survey questionnaire to Work-leader of various contractor company that work in the Plant. The data was analysed using the Exploratory Factor Analysis (EFA), Confirmatory Factor Analysis (CFA) to confirm the five Permit To Work elements construct. The Structural Equation Model was performed to identify most significant element related to failure of Permit To Work, and it was found that the hazardous activity and worksite inspection are the main element contributed to occupational accident in the Petrochemical Plant.The result of all the study has indicated that the Permit To Work and their element play important roles and it must be fully comply in every Permit To Work Process for work that need to be done in the Petrochemical Plant to ensure no accident occurred at Petrochemical Plant. This is Part 1 of two paper, focusing on PTW Assessment. Part 2 deal with PTW Accident Model, PTW in Bow Tie, Predictive Modelling and Case Study.
