The Mine Safety and Health Administration (MSHA) has released the investigation report on a June 13, 2013, fatality at a stone operation. The incident involved a 50-year-old mechanic with 15 years of experience who was killed when an articulated haul truck went out of control, overturning the bed and ejecting the victim from the upright cab.
MSHA recommends the following best practices for operating mobile equipment:
Always wear a seat belt when operating self-propelled mobile equipment.
Do not operate mobile equipment with reported brake problems. Use other means to move the mobile equipment to a safe area for inspection and repair.
Ensure that mobile equipment operators are task trained adequately in all phases of mobile equipment operation, including the mobile equipment’s capabilities, operating ranges, load-limits and safety features, before operating mobile equipment.
Maintain equipment steering and braking systems in good repair and adjustment. Always follow the manufacturer’s service and maintenance schedules.
Never rely on engine brakes and transmission retarders as substitutes for keeping brakes properly maintained.
Conduct adequate pre-operational checks to ensure the service brakes will stop and hold the mobile equipment prior to operating.
Operators of self-propelled mobile equipment shall maintain control of the equipment while it is in motion.
Operating speeds shall be consistent with conditions of roadways, tracks, grades, clearance, visibility, curves, and traffic.
Do not attempt to exit or jump from moving mobile equipment.
