Understanding COMAH Reports: Key Insights & Practical Guidance

Understanding COMAH Reports: Key Insights & Practical Guidance

The Control of Major Accident Hazards (COMAH) regulation, introduced in 1999 and revised in 2015, mandates that any business storing or handling hazardous substances at specified volumes must develop a comprehensive safety case. This requirement, enforced by the Health and Safety Executive (HSE), protects people, assets, and the environment.

While the legal framework is clear, the language of COMAH reports can be intimidating for non‑experts. Common questions include:

• Which COMAH tier applies to my organisation?
• How can I transform the report into a “living document”?
• How can the report be used day‑to‑day?

DEKRA Organisational & Process Safety has addressed these challenges through a targeted webinar series designed to demystify COMAH requirements and embed safety culture.

Webinar Series Overview

Webinar 1: COMAH Deconstructed – What You Need to Know

This foundational session explains the three regulatory tiers, outlines the structure of a COMAH report, and clarifies the responsibilities of each section. A recorded version is now available here.

Webinar 2: Top Tips to Make Your COMAH Report a Living Document

Building on the first webinar, we explore engagement strategies that make the report accessible to every employee. The HSE’s “living document” requirement means the report must evolve with your operations. Join us on 19 January 2022 at 2 pm GMT. Register now.
