Abstract

BACKGROUND AND OBJECTIVE: In industries, CONSTRUCTION phase is one of the high risk activities that involve with many problems. One of these problems is injuries wide spectrum as considerable portion of lost days allocate in this phase. According to the importance and expansion of petrochemical CONSTRUCTION projects, in this study the comprehensive safety assessment has been conducted with the goal of determining the potential existing hazards and decreases the occupational accident level. METHODS: In this study, ET& BA method (to safety analysis) and qualitative risk assessment has been applied. For this purpose, the risk matrix presented in the MIL-STD-882E has been used. This matrix shows the qualitative classification of the intensity and possibility of occurrence of accidents.FINDINGS: According to the results of this study, a total of 144 hazardous zones were identified. Based on the MIL-STD-882E Standard, 68% of the cases were in the high-risk zone, 30% were in the important risk zone and 2% were in the average risk zone. Meanwhile, working on scaffoldings has had the most number of high risks (23 cases) and the other sections including excavation, working at height, electrical, welding and cutting operations are placed in the next level of importance with 21, 19, 13 and 11 high-risk cases, respectively. With due to the results, nearly the majority of identified points are in the high-risk zone and important zone (98%), which is unacceptable according to the MIL-STD-822E.CONCLUSION: Hence, the necessity of conducting appropriate controlling measures including the establishment of supervision and inspection systems, preventive repairing, and applying standard and safe techniques and methods are some of the proposals which leads to a drop in the possible risks.
