A dumper driver lost control of his vehicle in trying to handle a speed bump. The backside of the dumper skidded along the track and turned over between 2:30 and 3 pm in a gneiss quarry after passing a bund wall without the requisite height at over 20 km/h. The driver, a subcontracted employee, was slightly injured. The lubricants spilling onto the ground were covered with sand and discarded by a specialist.
The inspection authorities for classified facilities visited the quarry that same day and the next day. Extraction operations were suspended until 2 March. Several recommendations were issued to the operator: bring the track up to code and improve its state of repair, increase distance between the end of the track and the beginning of the upward slope, raise the bund walls, and upgrade the site’s road signs.
