Overturned Water Truck
A loaded Eculid Water Truck was involved in a potentially
serious accident at a District 8 surface mine. The truck had
partially traveled up a spoil ramp leading from the pit when the
engine stalled. The truck lost all power assist steering
functions and the engine retarder also became inoperable. This
truck was not equipped with emergency steering. The operator
quickly called on his radio for all persons and equipment to stay
clear of the moving truck. As the truck rolled backwards down the
ramp, the operator attempted to apply both the service brake and
the park brake, however, neither would slow the truck. The truck
continued to travel backward until it struck the toe of the
spoil, located approximately 60 feet away. On impact, the load of
water shifted to the left side of the truck, causing the truck to
overturn. The operator was wearing his seatbelt, which prevented
serious injury. He was treated at a nearby hospital for slight
contusions and irritation of the right eye due to a particle of
broken glass. The employee was released for work by the hospital
the same day after receiving treatment.
BEST PRACTICES
- Always make complete and thorough pre-operational equipment
checks.
- Truck brakes should be frequently tested and capable of
holding a full load on both ascending and descending grades.
- Equipment seatbelts should be provided and used at all times
during operation.
- Establish and maintain communications with all trucks and
mobile equipment.
