Life-Saving Rules

Safety is a top priority for TenneT. We want everyone who works for us to come home safely, every day. That is why TenneT has eight Life-Saving Rules in combination with the Fair Approach.

8 Life Saving Rules

Life-Saving Rules (LSR) have proven their value in preventing fatal accidents.

They have been created to keep our people and the people who work for us safe. We have analysed serious incidents and risks within our organization and have developed eight Life-Saving Rules to help prevent accidents.

The Life-Saving Rules provide a framework and guidance for working safely. It is therefore very important that everyone who works for TenneT, not only our own employees, but also contractors’ employees, knows the eight Life-Saving Rules, follow them and know how to apply them in their daily work. When a Life-Saving Rule is broken, the Fair Approach will come into effect. Always follow the Life-Saving Rules, for your own safety and that of others.

The FAIR Approach

The Fair Approach is an instrument to identify the underlying causes why someone has broken a Life-Saving Rule.
It could be that someone is unaware that a certain rule applies in a specific situation, or thinks he/she cannot perform his/her work without breaking a rule, or he/she thinks to know a better and more effective method to complete their work.

The Fair Approach is based on the assumption that employees come to work to do good job, not with the intention of breaking rules.
In practice the Fair Approach means that anyone who sees a person breaking a Life-Saving Rule, reaches out to the person who broke the rule. Aim is to find out why he/she has broken the Life-Saving Rule in order to learn from it and define organisational measures to prevent similar breaches in future.

There is an interactive e-learning on the eight Life-Saving Rules and the Fair Approach in English, Dutch and German. You can find it in the TenneT Academy.
