Implementing OHSAS 18001:2007 for Effective OH&S Management

Workplace safety isn’t just about compliance-it’s about protecting your most valuable asset: your people. OHSAS 18001:2007 provides organizations with a systematic framework to identify workplace hazards, minimize risks, and continuously improve their occupational health and safety performance. Whether you’re in food manufacturing, logistics, or any other industry where workplace risks exist, understanding how to effectively use this standard can transform your safety culture.

Understanding OHSAS 18001:2007 🔗

OHSAS 18001:2007 stands for Occupational Health and Safety Assessment Series, a British Standard that became the first internationally recognized framework for occupational health and safety management systems. Published by the British Standards Institution (BSI), this standard was developed in response to organizations worldwide needing a unified approach to managing workplace health and safety.

The standard provides requirements for an OH&S management system, enabling organizations to control their occupational health and safety risks and improve performance. It does not prescribe specific performance criteria or detailed specifications for system design-instead, it offers a flexible framework that can be adapted to any organization, regardless of size or industry.

Core components of the standard 🔗

An occupational health and safety management system under OHSAS 18001:2007 comprises several essential elements. These include policies, processes, plans, practices, and records that define how your organization manages workplace safety. The standard requires you to establish, document, implement, maintain, and continually improve your system according to its specified requirements.

Key areas addressed by the standard include hazard identification, risk assessment and determining controls, legal compliance, emergency preparedness, performance monitoring, and management review. The structure aligns closely with ISO 14001 for environmental management and ISO 9001 for quality management, making it easier for organizations to integrate multiple management systems.

The Plan-Do-Check-Act methodology 🔗

At the heart of OHSAS 18001:2007 lies the Plan-Do-Check-Act (PDCA) cycle, a continuous improvement model that organizations use to develop, implement, and enhance their safety management systems. This iterative approach ensures that safety practices are not static but evolve based on performance data and changing conditions.

The PDCA cycle, also known as the Deming cycle, originated in the 1920s through Walter Shewhart’s work and gained further development in the 1950s through W. Edwards Deming. It has since become fundamental to management systems worldwide, providing a systematic method for problem-solving and process improvement.

Plan: establishing your foundation 🔗

The planning phase involves identifying where your organization currently stands and determining where you want to be. This stage focuses on two key elements: policy development and implementation planning. You must establish an OH&S policy that reflects your organization’s commitment to worker protection and legal compliance.

During planning, organizations should conduct thorough risk assessments to identify workplace hazards and evaluate their potential impact. Questions to address include: What risks exist for employees, visitors, and contractors? What regulations must be followed? What are current performance levels? What controls and safe systems of work are needed?

Setting clear, measurable objectives and key performance indicators is essential. These benchmarks allow you to track progress and evaluate whether your safety initiatives are achieving their intended outcomes.

Do: implementing your plans 🔗

The implementation phase transforms plans into action across three critical areas: profiling health and safety risks, organizing resources and responsibilities, and executing your safety plans. This is where your documented procedures come to life through day-to-day operations.

Effective implementation requires clearly defined roles and responsibilities, robust communication procedures, and competent personnel at all levels. Organizations must ensure that risks are adequately controlled through appropriate measures, proper maintenance procedures are established, and workers receive adequate information, instruction, training, and supervision.

Employee participation is particularly important during this phase. OHSAS 18001 requires organizations to involve workers in hazard identification, risk assessment, determining controls, and incident investigations. Consultation with contractors on changes affecting their health and safety is also mandatory.

Check: measuring performance 🔗

The checking phase evaluates whether your safety management system is working effectively. Performance measurement helps identify problems, understand why issues arose, and determine what changes are necessary. This stage involves both proactive (leading) and reactive (lagging) indicators.

Monitoring methods include regular equipment inspections, job observations to verify workplace precautions, health surveillance programs, and environmental monitoring such as measuring noise or dust levels. Incident investigations also fall under this phase, requiring documentation and root cause analysis to prevent recurrence.

Internal audits are a crucial checking mechanism. These audits assess whether your system complies with planned arrangements, has been properly implemented, and meets policy objectives. The standard requires evaluation of compliance with legal and other requirements the organization has subscribed to.

Act: driving continuous improvement 🔗

The final phase focuses on taking corrective actions based on findings from the checking stage and pursuing continuous improvement. When issues are identified-whether through audits, inspections, or incident investigations-organizations must respond promptly to address root causes and implement preventive measures.

If performance measurements reveal problems, you act upon them and implement remedies. For example, if noise monitoring shows machinery exceeds legal limits, you would address this issue and then cycle back through the PDCA process to plan and implement solutions. This iterative nature ensures your safety system continuously evolves.

Management review is an essential component of the Act phase. Top management must periodically review the OH&S management system to ensure its continuing suitability, adequacy, and effectiveness, making decisions about resource allocation and system improvements.

Certification to OHSAS 18001 🔗

While certification to OHSAS 18001 is voluntary, many organizations choose to have their systems externally audited by an accredited certification body (registrar) to demonstrate compliance. Third-party certification provides independent verification of your commitment to employee health and safety.

The certification process 🔗

Achieving certification typically follows a structured path. Organizations begin by understanding the standard requirements and conducting a gap analysis to compare current practices against requirements. This identifies specific areas needing improvement before formal audits.

The certification audit consists of two stages. Stage 1 involves document review to verify your management system design meets requirements. Stage 2 is an on-site audit confirming that your system is effectively implemented and operates in compliance with the standard. If auditors identify nonconformances, your certification depends on implementing corrective actions and having them verified.

Upon successful audit completion, the certification body issues a Certificate of Registration typically valid for three years. Regular surveillance audits-usually at six or twelve-month intervals-maintain certification validity by confirming continued compliance.

Benefits of certification 🔗

Certified organizations demonstrate to employees, customers, and stakeholders their commitment to workplace safety. This can enhance brand reputation and provide competitive advantage. Many companies also experience cost savings through reduced incidents, fewer workers’ compensation claims, and more favorable insurance rates.

The systematic approach required for certification often improves overall operational efficiency. By establishing clear processes for hazard identification, risk assessment, and incident management, organizations can better protect their workforce while meeting legal obligations.

Transition to ISO 45001 🔗

It’s important to note that OHSAS 18001 has been superseded by ISO 45001:2018, the first international standard for occupational health and safety management systems published by the International Organization for Standardization. Organizations previously certified to OHSAS 18001 were required to transition to ISO 45001 by March 2021.

ISO 45001 maintains the PDCA methodology while incorporating updates to address modern workplace challenges. The new standard uses a high-level structure common to other ISO management system standards, further facilitating integration of quality, environmental, and safety systems.

Practical implementation tips 🔗

Successfully implementing an OH&S management system requires commitment from all organizational levels, particularly top management. Leadership must demonstrate visible commitment to safety, allocate adequate resources, and actively participate in system reviews and improvement initiatives.

Engage stakeholders throughout the process-employees often have valuable insights into workplace hazards and practical solutions. Maintain detailed documentation of procedures, findings, and corrective measures while ensuring effective communication across all levels of the organization.

Consider using management system software to streamline documentation, track performance metrics, and manage audit schedules. Such tools can significantly reduce administrative burden while improving consistency and accessibility of safety information.
