標準簡介
OHSAS 18001 曾是國際公認的職業健康與安全管理系統標準。它為組織提供識別、控制和降低工作場所危害的框架，同時確保法規合規並改善員工安全。自 2018 年 3 月起，OHSAS 18001 已被 ISO 45001:2018 取代。
先前通過 OHSAS 18001 認證的組織，須於 2021 年 9 月前完成轉換至 ISO 45001。新的 ISO 45001 標準更加強調領導階層參與、員工參與、風險與機會管理，並透過高階結構（HLS）與其他 ISO 管理系統標準接軌。
Hazard Identification
Systematic approach to identifying workplace hazards, assessing risks, and implementing controls to prevent injury and ill health.
Migration to ISO 45001
OHSAS 18001 was withdrawn in March 2021. Organizations must transition to ISO 45001:2018 to maintain certified OH&S management.
Worker Participation
Emphasizes consultation with workers on occupational health and safety matters, including risk assessment and incident investigation.

Who Needs to Comply?
Organizations that were certified to OHSAS 18001 must migrate to ISO 45001:2018. The standard was historically used by manufacturing, construction, mining, and logistics companies.
Key Requirements
Hazard Identification
Establish procedures to identify hazards, assess OH&S risks, and determine necessary controls using the hierarchy of controls (elimination, substitution, engineering, administrative, PPE).
Legal Compliance
Identify and maintain access to applicable OH&S legal requirements. Periodically evaluate compliance with these obligations.
Operational Control
Implement and maintain controls for identified risks including safe work procedures, permit-to-work systems, and contractor management.
Incident Investigation
Investigate incidents and nonconformities to determine root causes, identify corrective actions, and identify opportunities for preventive action and continual improvement.
Penalties & Enforcement
No direct legal penalties for non-certification. OHSAS 18001 certificates are no longer valid after March 2021. Organizations must transition to ISO 45001 or lose their certified status.
