Hazard identification, risk assessment, and control at PT. Kharisma Iskandar Muda's Clarification Station: An HIRARC approach

Abstract

Occupational safety and health are critical for organizational stability and legal compliance. This study aims to identify hazards, assess risks, and develop control measures at the Clarification Station of PT Kharisma Iskandar Muda using the Hazard Identification, Risk Assessment, and Risk Control (HIRARC) method. This qualitative case study involved five informants, including an HSE officer, a process assistant, and station operators. The findings identified four key activities as major risk sources. Risks were classified into four levels: light (score 4), moderate (8), substantial (12), and extreme/unacceptable (20). Control measures were formulated based on the Hierarchy of Controls, ranging from elimination to Personal Protective Equipment (PPE). Specific recommendations include maintaining workplace cleanliness, conducting daily monitoring, installing safety signage, strictly adhering to Standard Operating Procedures (SOPs), and utilizing SNI-compliant PPE. The study concludes that relying solely on administrative controls is insufficient due to observed unsafe behaviors. Therefore, integrating engineering controls and fostering a strong safety culture are essential for effective risk management.
