Guide to Implementing the ISO 45001:2018 Standard
International Occupational Health and Safety (OH&S) Management System.
What is ISO 45001 and why is it important?
ISO 45001:2018 is an international standard that provides a framework for organizations to proactively improve their occupational health and safety performance, preventing injuries and ill-health in the workplace. This standard replaced the older OHSAS 18001.
Its key goal is not just mere compliance with legal norms, but building a safety culture where organizational leadership and the workers themselves take an active role in identifying and eliminating risks.
Benefits of implementing ISO 45001
Companies with a certified system record significant business benefits:
- Cost reduction: Fewer injuries mean lower costs for sick leave, insurance premiums, and legal disputes.
- Competitive advantage: Many public tenders and large international corporations require an ISO 45001 certificate from their suppliers and contractors.
- Worker satisfaction: Workers feel safer, leading to higher productivity and lower staff turnover.
- Legal compliance: The standard automatically forces the company to track and comply with all local OH&S laws.
High Level Structure (HLS)
ISO 45001 uses the same 10-chapter structure (HLS) as ISO 9001 (Quality) and ISO 14001 (Environment). This means it is very easy to integrate (so-called Integrated Management System - IMS) into existing ISO certificates the company already holds. If you already have ISO 9001, half the work regarding documentation (document control, internal audits, management review) is already done!
7 Key Steps to Certification
The implementation process usually takes between 6 and 12 months, depending on the company size:
- 1. Gap Analysis: Comparing the current OH&S state with what the standard requires.
- 2. Policy and Objectives: Management must sign the OH&S policy and set measurable goals (e.g., "0 accidents this year").
- 3. Worker Participation: Workers must be consulted about hazards (via safety representatives).
- 4. Risk and Opportunity Assessment: Identifying hazards and establishing operational controls (which are then implemented through work instructions).
- 5. Education and Communication: Employee training on new procedures.
- 6. Internal Audit: Internal review of the system.
- 7. Certification Audit: Visit by an independent certification body (e.g., TÜV, SGS, Bureau Veritas, DNV).
Mandatory Documentation According to the Standard
For a successful audit, you will need to present the following documents (documented information) to the auditor:
- Scope of the OH&S management system.
- Health and Safety Policy.
- Criteria for evaluating risks.
- Legal register (list of laws you must comply with).
- Emergency preparedness and response plans (Evacuation plan).
- Records of incidents and nonconformities (corrective actions).
- Records of training and audits.
