Control of Major Accident Hazards (COMAH) Regulations 2015: Ensuring Safety in Complex Industrial Operations
Control of Major Accident Hazards (COMAH) Regulations 2015 represent a fundamental legal framework designed to prevent and mitigate serious accidents involving dangerous substances at industrial sites across the United Kingdom. These regulations are part of the UK’s commitment to safeguarding human health, the environment, and property from the catastrophic consequences of major accidents in the chemical, petrochemical, and other hazardous industries.
Introduced under the European Union’s Seveso Directive, the COMAH Regulations 2015 came into force to update and streamline previous legislation, ensuring better safety management, clearer responsibilities, and improved emergency preparedness. This comprehensive legal system is vital for operators, regulators, and local communities, emphasizing proactive risk management and accountability.
Background and Context of COMAH Regulations 2015
Origins and Evolution of COMAH Legislation
The Control of Major Accident Hazards Regulations have their roots in the EU Seveso Directives, first enacted in 1982 and subsequently revised to improve safety standards. The UK transposed these directives into national law, with the initial regulations introduced in the 1990s. The 2015 update reflects ongoing advancements in safety science, industrial practices, and regulatory approaches.
The key objectives of the COMAH Regulations are to:
- Prevent major accidents involving dangerous substances
- Limit the consequences of such accidents for people and the environment
- Ensure effective emergency preparedness and response
Scope of the COMAH Regulations
The regulations apply to establishments that handle or store dangerous substances above specified thresholds. These include chemical manufacturing plants, fuel storage facilities, pharmaceutical manufacturing units, and other industrial sites where hazardous materials are present.
There are two categories of establishments under COMAH:
- Top-tier establishments: Larger sites with significant quantities of dangerous substances, requiring comprehensive safety management systems and notification to the competent authority.
- Lower-tier establishments: Smaller sites with lesser quantities, subject to certain safety obligations but less complex regulatory requirements.
Key Provisions of the COMAH Regulations 2015
1. Safety Management and Prevention Measures
The cornerstone of COMAH compliance is the implementation of robust safety management systems (SMS). Operators are mandated to:
- Identify hazards and evaluate risks associated with dangerous substances
- Establish and maintain safety management procedures
- Train staff appropriately and ensure awareness of hazards
- Implement control measures to prevent major accidents
2. Safety Reports and Emergency Plans
Operators must prepare and submit detailed safety reports to the competent authority, covering:
- Details of dangerous substances handled
- Risk assessments and safety measures
- Emergency plans and procedures
Additionally, comprehensive emergency plans must be developed, tested, and coordinated with local emergency services to ensure swift response during incidents.
3. Major Accident Prevention Policy (MAPP)
Establishing a MAPP is a legal requirement for top-tier establishments. It sets out the company’s commitment to preventing major accidents and outlines the safety objectives, organizational responsibilities, and safety culture within the organization.
4. Notification and Reporting Obligations
Operators are legally obliged to notify the competent authority of:
- Accidents that cause or could cause major hazards
- Changes in the nature or quantities of dangerous substances
- Incidents or near misses that could escalate into major accidents
5. Inspections, Enforcement, and Compliance
The Health and Safety Executive (HSE) or the relevant authority conducts regular inspections to ensure compliance. Non-conformance can lead to enforcement actions, including notices, penalties, or even site shutdowns.

Implementing Effective Control of Major Accident Hazards
Risk Assessment and Management
Core to COMAH compliance is thorough risk assessment, which involves identifying hazards, evaluating risks, and implementing control measures. Techniques include:
- Layered safety barriers
- Process safety management
- Regular maintenance and inspection
- Incident analysis and learning from past events
Safety Culture and Workforce Engagement
A strong safety culture is essential. Employers should foster open communication, encourage reporting of hazards, and involve staff at all levels in safety initiatives.
Emergency Preparedness and Response
Effective emergency plans must be regularly tested through drills and updated based on lessons learned. Coordination with local emergency services is critical for rapid response and minimizing impact.
Benefits of COMAH Compliance
Adhering to COMAH regulations offers multiple advantages:

- Balancing operational efficiency with safety priorities
Future Developments
The regulatory landscape continues to evolve with technological advancements and lessons learned from incidents worldwide. Future initiatives may include:
- Increased use of digital safety management tools
- Enhanced community engagement and transparency
- Stronger focus on sustainability and environmental safety
Conclusion
The Control of Major Accident Hazards (COMAH) Regulations 2015 serve as a vital framework for managing the risks associated with hazardous substances in industrial settings. By establishing clear responsibilities, rigorous safety management requirements, and robust emergency preparedness measures, COMAH aims to prevent accidents and mitigate their consequences should they occur. Compliance not only protects lives and the environment but also enhances operational resilience and corporate responsibility. As industries continue to evolve, ongoing commitment to safety, innovation, and community engagement will be essential for maintaining a safe and sustainable industrial sector in the UK.
