Yellow Book

"Praxis High Integrity Systems Ltd has been closely involved with the Engineering Safety Management handbook, or the Yellow Book as it is more commonly known, since 1992. In this time, they have contributed significantly to the development and dissemination of good system safety engineering practice within the UK rail industry. Praxis High Integrity Systems continue to provide a professional focus for Yellow Book training, user group management and Yellow Book improvement."
Rod Muttram, Railway Safety

Praxis High Integrity Systems led the development of the "Yellow Book" from its inception in 1992. The Yellow Book (also known as "Engineering Safety Management") provides in-depth guidance on managing safety in the railway industry. The Yellow Book guidance takes the best ideas from across industry and shows how projects can achieve and demonstrate acceptable levels of safety. The guidance is scalable to project size and level of risk.

Praxis High Integrity Systems is represented on the Yellow Book Steering Group.

We have a proven track record in working alongside organisations who need to produce safety cases in the rail industry and provide several levels of support including:

• planning the safety approach for your project setting up the framework which allows you to compile the safety case which you need
• training your staff in safety management
• enhancing the capability of your organisation by coaching your staff
• providing a safety management system for your organisation
• compiling your safety case for you

We will work with you to choose the level of support most suited to your needs.

The Praxis High Integrity Systems approach to safety is aligned with the Yellow Book guidance and is aimed at providing the evidence you need to gain acceptance from your regulator and operator (e.g. HMRI in the UK, or ProRail in the Netherlands).
