In high-hazard industries such as oil & gas, petrochemicals, energy, and process manufacturing, managing Major Accident Hazards (MAHs) is critical to ensuring workforce safety, asset integrity, and regulatory compliance.
Our MAH Critical Tasks (MCTs) and MAH Management Services are designed to systematically identify, assess, and control high-consequence risks using globally recognized process safety methodologies and human factors engineering principles.
What is a Major Accident Hazard (MAH)?
A Major Accident Hazard (MAH) is a high-impact risk scenario that can lead to catastrophic outcomes such as:
- Multiple fatalities or serious injuries
- Large-scale equipment or facility damage
- Environmental pollution or long-term ecological impact
Although the likelihood of such events is typically low, the severity of consequences makes MAH management a top priority in process industries.
Common Sources of MAHs:
- Storage and handling of hazardous chemicals beyond threshold limits
- High-pressure and high-temperature process operations
- Flammable, explosive, or toxic material releases
- Equipment failures and loss of containment
- Human errors in critical operations
Our MAH Identification & Risk Assessment Approach
We adopt a structured and data-driven methodology to identify and evaluate MAHs across the facility lifecycle.
Key Techniques Used:
- Hazard Identification (HAZID): Early-stage hazard recognition through multidisciplinary workshops
- HAZOP & LOPA Studies: Detailed process deviation analysis and risk quantification
- Bow Tie Analysis: Visualization of threats, consequences, and safety barriers
- Site Safety Audits: Real-time verification of plant conditions and operational practices
Typical MAH Scenarios Assessed:
- Fire events (jet fire, pool fire)
- Explosion scenarios (VCE, BLEVE)
- Toxic gas dispersion and exposure
MAH Critical Tasks (MCTs) – Ensuring Operational Safety
What are MCTs?
MAH Critical Tasks (MCTs) are safety-critical activities performed by personnel that directly prevent, control, or mitigate major accident scenarios.
A task is classified as an MCT when failure to perform it correctly can:
- Trigger a major accident event
- Escalate an ongoing hazardous situation
- Compromise Safety Critical Elements (SCEs)
Our MCT Identification & Assessment Methodology
We follow a systematic approach to define and validate MCTs within your facility.
Step-by-Step Process:
- Data Collection & Review
- HAZOP, LOPA, and SIL reports
- Operating procedures and maintenance manuals
- Incident history and safety documentation
- Task Identification
- Mapping tasks linked to MAH prevention and mitigation
- Linking human actions to safety barriers
- Competency & Gap Analysis
- Evaluating workforce skills and training levels
- Identifying gaps against international standards
- Performance Standards Development
- Defining clear execution criteria for each MCT
- Establishing measurable performance indicators
Human Factors Assessment (HFA) for MCTs
Human reliability plays a critical role in MAH prevention. Our Human Factors Assessment (HFA) ensures that personnel can perform MCTs effectively under real operational conditions.
Key Human Factors Considered:
- Operator workload and fatigue conditions
- Human-machine interface (HMI) effectiveness
- Clarity and usability of procedures
- Decision-making under emergency stress
- Accessibility, escape, and evacuation constraints
We use structured checklists, field observations, and workforce interviews to validate human performance capability.
MCT Register & Compliance Documentation
We develop a comprehensive MCT Register tailored to your facility, ensuring full traceability and compliance.
Includes:
- Detailed list of MAH Critical Tasks
- Personnel competency and training records
- Performance standards and verification criteria
- Audit findings and corrective actions
- Workshop outcomes and approvals
ALARP-Based Risk Reduction Strategy
We apply the ALARP (As Low As Reasonably Practicable) principle to ensure that all risks are reduced to acceptable levels through cost-effective measures.
Hierarchy of Controls Applied:
- Elimination of hazards
- Substitution with safer alternatives
- Isolation and segregation
- Engineering controls and safeguards
- Administrative and procedural controls
- Personal Protective Equipment (PPE)
Cost-Benefit Analysis (CBA)
Our approach includes Cost-Benefit Analysis (CBA) to evaluate the practicality of implementing risk reduction measures, ensuring optimized safety investments without unnecessary expenditure.
MCT Workshops & Stakeholder Engagement
We facilitate structured workshops involving cross-functional teams and independent experts to validate findings.
Workshop Deliverables:
- Verified MCT list for each facility
- Gap analysis results and recommendations
- Defined competency requirements
- Human factors evaluation outcomes
- Clear linkage between hazards, barriers, and tasks
MAH Management & Safety Case Support
Our services support the development and enhancement of MAH Management Systems and Safety Cases, ensuring alignment with international process safety frameworks.
Key Elements Covered:
- Hazard identification and classification
- Consequence and risk analysis
- Safety Critical Elements (SCEs) definition
- Barrier-based risk management
- Emergency response planning
Safety cases demonstrate how MAHs are:
- Prevented through design and controls
- Detected using monitoring systems
- Controlled and mitigated through safeguards
- Managed during emergency response and recovery
