Everyone needs to do risk assessment. You can’t do good work with poor tools and the risk matrices used by many companies are poorly designed and often misunderstood by the people who use them. If you need to build a well-designed and highly-functional risk matrix, you need to read this book. Learn how to set risk targets, specify consequence and likelihood criteria and design a risk matrix that reflects your organisation's attitude to risk.

The book is written by a chemical engineer who has over twenty-five years experience dealing with major chemical risks.

This book has not been updated since its publication in 2013. However it still offers good advice.
