Our Response to an Industrial Accident at Parts Operation in Komatsu Europe International N.V.

On September 8, 2015, at Parts Operation in Komatsu Europe International N.V. in Brussels, Belgium, two order pickers (high-place work vehicle) collided. One vehicle was overturned and the operator riding on it fell to the ground with the vehicle, sustained serious injuries including skull fracture and brain contusion, and died on September 25.
The local and Japan's safety representative and production engineers worked together to determine the cause of the accident and proposed an accident countermeasure, and a special safety activity was held at Komatsu Europe.
Causes:              - Both rules of not parking within the work lane and no more than 2 vehicles entering the same lane at
                             one time had been broken.
                           - There was no visual check of the front/back/left/right before moving the vehicle.
Interim Measures:    - Implement reminders and re-education for operators
                              - Inspection/maintenance of work environment   (Example: internal lights always on)
Permanent Measures: - Prevent work vehicles from contacting or colliding with each other by using sensor alarms.
                                 - Prevent overturning of work vehicles by using guide rails.
These measures were notified across the domestic and overseas work places that similarly use high-place work vehicles in handling parts.
