ISMS partners have investigated the reasons why ground personnel on platforms and service roads do not always comply with the rules and regulations. This research demonstrates several factors at play. To improve this situation, we have now implemented measures that were feasible at short notice. Enforcement of wearing seatbelts in vehicles on airside is intensified and engine start is possible with a pass only. We have also introduced stricter airside access rules. The longer-term safety improvements are currently worked out in a study or implemented. The implementation date above refers to the safety improvements which are currently being implemented. For the safety improvements which are currently in study, the implementation date might be updated.
