Safety/HSE Cases

Learn how to develop, present, and maintain Safety/HSE Cases that meet regulatory requirements, demonstrate ALARP, and align with organisational safety management systems. Gain practical skills to build clear claims, arguments, and evidence, and ensure the Safety Case remains a living document throughout the asset lifecycle.

Prerequisites

Basic understanding of major accident hazard management or process safety is recommended. Prior experience with safety cases is helpful but not required.

How Can I Demonstrate ALARP?

Understanding and applying the ALARP principle is key to effective risk management and legal compliance in safety-critical industries.

Safety Cases and Safety Reports

A Safety Case or HSSE (Health, Safety, Security & Environmental) Case demonstrates that a high-hazard facility has identified its major accident hazards, assessed the associated risks, and implemented sufficient controls to reduce those risks to a tolerable or ALARP level. Safety cases are tailored to industry, site-specific, and regulatory requirements, providing assurance to regulators, workforce, and stakeholders that risks to people, the environment, and assets are systematically identified, managed, and continuously monitored. They play a central role in regulatory regimes such as the Nuclear Installations Act, UK Offshore Installations (Safety Case) Regulations, COMAH Regulations, and Seveso III Directive.

COMAH Services

The COMAH (Control of Major Accident Hazards) Regulations apply to UK facilities handling significant quantities of dangerous substances. Achieving COMAH compliance means demonstrating robust safety management systems, effective risk reduction, and emergency preparedness to protect people and the environment from major accident hazards, aligned with UK legislation and European Seveso III requirements.

Hazardous Substances Consent (HSC)

Hazardous Substances Consent (HSC) is a legal requirement in the UK under the Planning (Hazardous Substances) Regulations, ensuring that sites storing or using dangerous substances above specified thresholds assess, manage, and communicate their major hazard risks. HSC supports safe land use planning, protects surrounding communities, and aligns with broader regulatory frameworks such as the COMAH Regulations and Seveso III Directive. We help organisations navigate HSC applications, renewals, and ongoing regulatory engagement to maintain compliant, safe, and sustainable operations.

Quantitative Risk Assessment (QRA)

Quantitative Risk Assessment (QRA) systematically estimates the likelihood and consequences of hazardous events, including fires, explosions, and toxic releases. QRA provides a robust, data-driven basis for managing safety, environmental, and economic risks in high-hazard industries, supporting ALARP demonstration and informed decision-making.

Simultaneous Operations (SIMOPs) Assessment

Simultaneous Operations (SIMOPs) Assessment identifies and manages the additional hazards introduced when two or more high-risk activities, workgroups, or adjacent facilities operate concurrently. SIMOPs studies help prevent escalation, ensure operational control, and safeguard people, assets, and the environment by defining clear roles, interfaces, and controls.

HAZOP Study and Process Hazard Analysis (PHA)

HAZOP (Hazard and Operability Study) and Process Hazard Analysis (PHA) are structured techniques used to systematically identify hazards and operability issues in processes, systems, or facilities. By exploring how deviations from intended parameters can arise — using guidewords like more, less, none, reverse — teams can uncover credible causes, evaluate safeguards, and define risk-reduction actions. Originally developed for chemical processes, HAZOP is now widely used across industries, supporting compliance with standards.
