In today’s rapidly evolving industrial landscape, manufacturing safety remains a top priority for businesses worldwide. With the introduction of ISO 45001 in 2018, many safety managers and plant operators are left wondering about the status of the previous standard, ISO 18001 (OHSAS 18001). This comprehensive guide examines whether ISO 18001 still holds relevance in modern manufacturing environments and provides actionable insights for businesses navigating this transition.
ISO 45001 Replacement for ISO 18001: Understanding the Shift
The transition from ISO 18001 to ISO 45001 represents more than just a simple update – it’s a fundamental shift in how organizations approach workplace safety. The International Organization for Standardization (ISO) developed ISO 45001 to create a more robust, proactive framework for occupational health and safety management systems (OHSMS).
Key reasons for the replacement include:
-
Global standardization: ISO 45001 provides a unified approach accepted across all ISO member countries
-
Preventative focus: The new standard emphasizes hazard prevention rather than incident response
-
Leadership requirements: Top management must now demonstrate active involvement in safety programs
-
Worker participation: Employees at all levels must be consulted on safety matters
-
System integration: Designed to work seamlessly with ISO 9001 and ISO 14001
For manufacturing facilities still operating under ISO 18001 certification, it’s important to note that the standard was officially withdrawn in March 2021. While some organizations may continue referencing their existing ISO 18001 systems, all new certifications must now follow the ISO 45001 framework.
ISO 18001 vs ISO 45001 Manufacturing: Key Differences Explained
Understanding the differences between these two standards is crucial for manufacturing operations considering certification or transitioning between systems. Here’s a detailed comparison of how these standards approach workplace safety:
Structural Differences
ISO 45001 follows the High-Level Structure (HLS) common to all modern ISO management system standards, making it easier to integrate with quality (ISO 9001) and environmental (ISO 14001) management systems. ISO 18001 used a different structure that could create challenges when implementing multiple management systems.
Risk Management Approach
The older ISO 18001 standard focused primarily on hazard identification and control. ISO 45001 expands this concept to include both risk and opportunity assessment, encouraging manufacturers to consider potential safety improvements during operational changes or new process implementations.
Leadership and Worker Involvement
Perhaps the most significant change involves leadership requirements. Under ISO 45001, top management must demonstrate direct involvement in the OHSMS, rather than simply delegating responsibility to safety personnel. The standard also requires meaningful worker participation in safety decisions affecting their work areas.
Documentation Requirements
ISO 45001 offers more flexibility in documentation compared to ISO 18001. While manufacturers still need to maintain proper records, the newer standard allows organizations to determine the most effective way to document their safety processes based on their specific operations.
Performance Evaluation
The newer standard places greater emphasis on continuous monitoring and measurement of safety performance. Manufacturers must establish key performance indicators (KPIs) and regularly review their effectiveness in maintaining a safe work environment.
Upgrading from ISO 18001 to ISO 45001: A Practical Guide for Manufacturers
Transitioning from ISO 18001 to ISO 45001 requires careful planning and execution. For manufacturing operations, this process typically involves several key steps:
1. Gap Analysis and Planning
Begin by conducting a thorough gap analysis comparing your current OHSMS against ISO 45001 requirements. This should identify:
-
Processes that meet the new standard
-
Areas requiring modification
-
Completely new requirements to implement
Develop a transition plan with realistic timelines, assigning responsibilities to appropriate team members. Most manufacturers find the process takes 6-12 months depending on facility size and complexity.
2. Leadership Engagement and Training
Since ISO 45001 requires demonstrated leadership commitment, begin by educating executives and managers about their expanded roles. Training should cover:
-
New responsibilities under the standard
-
Risk-based thinking principles
-
Integration with other management systems
-
Performance evaluation requirements
3. Worker Consultation and Participation
Develop structured methods for worker involvement in safety matters. This might include:
-
Safety committee formation
-
Regular safety meetings
-
Hazard reporting systems
-
Participation in risk assessments
4. Documentation Updates
Review and revise all safety documentation to align with ISO 45001 requirements. Pay special attention to:
-
Safety policy statements
-
Risk assessment methodologies
-
Operational control procedures
-
Emergency preparedness plans
-
Performance monitoring systems
5. Implementation and Internal Auditing
Roll out changes in phases, starting with high-priority areas. Conduct internal audits to verify effectiveness before your certification audit. Many manufacturers find value in performing a mock audit to identify any remaining gaps.
6. Certification Audit
Schedule your official transition audit with an accredited certification body. The audit will verify your system meets all ISO 45001 requirements and properly addresses the transition from ISO 18001.
Maintaining Relevance in Modern Manufacturing
While ISO 18001 served manufacturers well for many years, ISO 45001 better addresses the complex safety challenges of modern manufacturing. The newer standard’s emphasis on leadership involvement, worker participation, and risk-based thinking creates a more dynamic and effective approach to workplace safety.
For manufacturers still operating under ISO 18001, the time to transition is now. The benefits of upgrading include:
-
Improved hazard prevention capabilities
-
Better alignment with other management systems
-
Enhanced worker safety culture
-
Continued recognition in global supply chains
-
Compliance with current international standards
By embracing ISO 45001, manufacturers can not only maintain their safety certifications but also implement a more robust, effective approach to protecting their most valuable asset – their workforce. The transition process, while requiring investment of time and resources, ultimately creates safer, more efficient manufacturing operations better prepared for the challenges of modern industry.
FAQ’s
1. Can companies still get certified to ISO 18001 in 2024?
No. ISO 18001 (OHSAS 18001) was officially replaced by ISO 45001 in March 2021. All new certifications must now follow the ISO 45001 standard.
2. What’s the main difference between ISO 18001 and ISO 45001?
The key difference is that ISO 45001 focuses on proactive risk prevention and requires leadership involvement, while ISO 18001 was more reactive and didn’t mandate management participation.
3. How long does transition from ISO 18001 to ISO 45001 take?
Most manufacturers complete the transition in 6-12 months, depending on facility size and complexity of existing safety systems.
4. Is ISO 18001 certification still valid if we don’t upgrade?
Existing ISO 18001 certificates expired after the 3-year transition period ended in 2021. Companies must now maintain ISO 45001 certification.
5. What happens if we keep using ISO 18001 procedures?
While you can maintain some legacy processes, you risk non-compliance with current international standards and potential issues with clients requiring ISO 45001 certification.
6. Does ISO 45001 require more documentation than ISO 18001?
Actually, ISO 45001 allows more flexibility in documentation. The focus is on effective risk management rather than rigid paperwork requirements.
7. How does worker participation differ between the standards?
ISO 45001 specifically requires consultation with workers on safety matters affecting them, while ISO 18001 only recommended such participation.
8. Can we integrate ISO 45001 with our existing ISO 9001 system?
Yes. ISO 45001 uses the same High-Level Structure as ISO 9001, making integration significantly easier than with the older ISO 18001 standard.
