Best Practices
- Always wear a seat belt when operating a haul truck or mobile equipment.
- Conduct thorough, in depth task training to cover potential hazards.
- Monitor employees regularly to ensure seat belts are worn when operating mobile equipment.
- Emphasize that improperly worn seat belts can NOT provide the proper restraint to necessary to protect equipment operators in hazardous situations.
- Conduct pre-operational checks to identify defects that may affect the safe operation of equipment before being placed into service.
- Observe all speed limits, traffic rules, and ensure that grades on haulage roads are appropriate for haulage equipment being used. Maintain control and stay alert when operating mobile equipment.
- Provide and maintain adequate berms and other barriers of mid-axle height.
- Perform safety inspections that include braking systems and seat belts before operating equipment; promptly remove equipment from service if defects affecting safety are found.
