Hazard Identification, Risk Assessment, and Control Design for Digital Design & Prototyping Laboratory at a University in West Java

Abstract

Background: The Digital & Design Prototyping Laboratory at a University in West Java (University X) faces various potential hazards due to the use of computers, 3D printers, electronic workstations, and shared equipment. This situation requires a systematic risk assessment to ensure user safety and compliance with OHS standards. This study aims to identify potential hazards in the Digital & Design Prototyping Laboratory, assess the likelihood and severity of the risks through a risk assessment, and formulate appropriate risk control recommendations. This study focuses on the physical, chemical, and ergonomic risks associated with prototyping activities to improve laboratory safety.

Methods: This study used the Hazard Identification, Risk Assessment, and Control (HIRAC) method, referring to ISO 45001:2018 and SMK3. Ten laboratory activities were analyzed based on likelihood and severity parameters using a 4x4 risk matrix. Data were collected through direct observation, potentially unsafe documentation, work accident records, and informal interviews with laboratory assistants.

Result: Initial assessments indicated several activities were at moderate to high risk levels, with the highest risk scores of 12, including tripping hazards from loose cables, electrical shock from computers, and biological exposure through shared computer equipment. Other activities had risk scores of 8–9, including floor storage, crowded spaces, food/drink spills, and ergonomic risks. After implementing additional controls such as cable management, improved housekeeping, space management, hygiene procedures, and ergonomic improvements, the risk scores for all activities decreased to the 3–8 range. Significant decreases were seen in electrical shock (12 → 4), spills (9 → 3), and ergonomics (8 → 4). Overall, the average risk score decreased from 9.4 to 4.6, representing a 51% risk reduction..

Conclusion: Implementing a hierarchy-based control system has the potential to reduce the level of risk in identified activities, provided the recommended control plan can be consistently implemented
