A mechanistic model for industrial workplace design based on inherent safety and health concepts

This study aims to establish a mechanistic model of using inherent safety and health concepts to conduct industrial workplace risk reduction strategies during the project planning stage. Accordingly, a dedicated implementation tool termed inherently safer and healthier design model for industrial workplaces (ISHDM-IW) is developed. First, the safety and health by design checklist is adapted to derive industrial workplace safety and health risk indicators. Then, the risk indicators are rated and weighted using the methods of risk matrix and precedence chart. Subsequently, the risk indicators are aggregated via fuzzy risk representation with the indicators' risk values and weights. Last, the inherent safety and health principles are used to do risk-based baseline design optimization. The case study demonstrates the capabilities of the proposed ISHDM-IW to upgrade the workplace design scheme from risk level II to risk level I, thus generating a more satisfactory workplace design alternative. The proposed ISHDM-IW offers a novel design mechanism of inherent safety and health for industrial workplaces, which can be expected to ensure employees' safety, health, and well-being with fundamentally better ergonomics of industrial work environments.
