Abstract

The alcohol warehouse at PT Phapros Tbk, Semarang, functions as a storage area for chemical raw materials-especially alcohol-used in a production process. In this sense, obviously, the warehouse has a high potential to cause a significant hazard because it contains flammable, reactive, and toxic materials. However, the company has not ever assessed the risk and hazard of the warehouse. Therefore, this study attempts to identify the potential hazard, to assess the associated risk, as well as to control the risk. The hazard identification, risk assessment and risk control (HIRARC) is used to achieve the objective of the study. This study highlights: hazard identification (including finding potential hazards), risk assessment (defining the risks and rating which is linked to the hazard based on severity and likelihood), and risk control (controlling of hazards and associated risks with the hazard). Three main activities in the warehouse, i.e., receiving, maintenance, and transferring materials, are evaluated. Result shows that in the receiving materials activity, about 3.45% of the potential risk is classified as an extreme risk and 37.93% of the potential risk is classified as high risk- while in the maintenance and transferring materials, respectively, about 44.44% and 54.17% of the identified risk are classified as high risk (no extreme risk is identified in these two activities). Finally, recommendations are provided to control the high and extreme risks to minimize hazards and associated risks.
