Life-Saving Rules

Life-Saving Rule systems have proven their value in reducing fatal accidents, which is why TenneT has developed and introduced an LSR system. This system consists of six Life-Saving Rules and the FAIR Approach (Flowchart Analysis of Investigation Results). The six Life-Saving Rules are particularly intended for preventing fatal and very serious accidents. We do not want our employees or those of (sub) contractors to risk their lives for TenneT. These six rules give you the right to say “No” and to stop work in situations defined within the LSR.

The 6 Life-Saving Rules

The TenneT life-saving rules are based on analyses of all our High-Risk Incidents (HRI) from the past years. We then derived the six most important rules for TenneT from these analyses while considering international standards in the oil and gas industry. These Life-Saving Rules present a collection of existing rules that are now being given a special status as they are crucial in preventing fatal or otherwise serious accidents. Compliance with these rules is therefore TenneT’s utmost priority.

TenneT has grown rapidly over the past few years: the number and scope of our projects, the size of our workforce, and the number of suppliers and (sub) contractors that we work with have all increased significantly. But this means that the risk of accidents is also increasing. Unfortunately, fatal accidents have occurred at TenneT – a few years ago and recently. We must do everything in our power to prevent this from ever happening again

The 6 Life-Saving Rules

  • Prevent dropped tools and equipment
  • Comply with electrical safety rules
  • Work with a valid work permit when required
  • Protect yourself against falling when working at height
  • Do not work, walk or stand under a suspended load
  • Use personal protective equipment when required
