Our key tasks

Learning from incidents

Everyone will agree that lessons can be learnt from accidents. But to do that, you first need to know what happened and why it happened. In short: an investigation needs to be conducted.

It is TenneT's policy to investigate incidents that have (or could have) led to severe injury, using the Tripod Beta method. Incidents with minor injuries, of the categories MTC (medical treatment case), RWC (restricted work case) and LWC (lost workday case) must also be investigated, but the choice of investigation method is free.

For contractors working for TenneT, the same rules apply. Apart from Tripod Beta however, they may use a different method. On this page, you can find a list of methods for incident investigation that are approved by TenneT. If you want to use another method still, please contact safety(at)tennet.eu so that we can review the method and, after consenting with it, add it to the list of approved investigation methods. You can find more information in the factsheet on this webpage.

TenneT has trained its SHE advisors in the use of the Tripod Beta method. We are always willing to help our suppliers with investigations using Tripod Beta. If you would like to increase your own organization’s expertise with regard to Tripod Beta, you can do this via one of the recognized training institutes in this field. 

A better understanding of the causes of an accident will allow us to take more effective measures. If we know the underlying causes, we can implement better strategies to prevent accidents in the future.

Life-Saving Rules

TenneT applies six Life-Saving Rules. These rules are intended to prevent fatal accidents, and are based on the safety standards applicable in the petrochemical industry and a careful analysis of past high-risk incidents at TenneT. TenneT employees or personnel working for our (sub)contractors should never feel pressured to risk their lives for the sake of the company. The six Life-Saving Rules empower employees to say 'No' and stop the work in any situation where a Rule applies.
