By expressing gratitude to the presence of Allah SWT, for the abundance of His grace and guidance, the writing of the book entitled Occupational Safety and Health: Concepts,Regulations, and Implementation can be completed. This book discusses the introduction to occupational safety and health, regulations and policies on OHS in Indonesia and internationally, hazard identification and risk assessment, OHS management systems, implementation of OHS in the workplace and occupational diseases.

Occupational Safety and Health (OSH) as a scientific discipline has undergone a significant paradigmatic shift over the past few decades, from a highly focused approach to technical protection from purely physical danger to a more hands-on approach systemic and risk-based. In the early stages of OSH development, the dominant concept of technical protection emphasized the use of personal protective equipment, basic safety procedures, and post
incident response to workplace accidents. However, criticisms of this model, including its reactive tendencies and lack of anticipation of complex hazards, have led to the emergence of a new approach that places risk assessment and risk management as the primary foundation of organizational safety. This modern approach integrates hazard identification, risk evaluation, and mitigation measures within a proactive and adaptive management system framework.
