Inherent occupational health assessment index for research and development stage of process design

Occupational health analyses the job and health relationships, in particular the chronic health influence of chemicals to workers. In most of the previous works for inherent hazards assessment, the focus was put on safety aspect; with very minor elements of health are taken into account. Most of the...

description Occupational health analyses the job and health relationships, in particular the chronic health influence of chemicals to workers.

Most of the earlier design stage assessment methods focus only on the hazard identification and assessment part; but not the risk mitigation element. This study aims to create an assessment method that integrate the existing inherent hazards assessment index which is the Inherent Occupational Health Index (IOHI) with suitable Layers of Protection (LOP) strategies for each of the enlisted hazard parameters. The IOHI considers the health hazards existed during research and development stage. Risk prevention and minimization strategies are proposed according to each hazard parameters and levels.
