renewcomerLeave a comment

ftl2013m03On March 27, 2013, a 61-year old loader operator with 24 years of experience was killed at a crushed stone operation. The victim was in a front-end loader about 50 feet from the base of a highwall when a blast was initiated. Broken rock struck the front-end loader and covered it. The rock was removed from the front-end loader and the victim was recovered about 10 hours after the blast occurred.

 

Best Practices

 

  • Do not initiate a blast until it has been determined that all persons have been evacuated from the blast area.
  • Establish and discuss safe work procedures. Identify and control all hazards associated with the work to be performed along with the methods to properly protect persons.
  • Task train all persons to recognize all potential hazardous conditions, to ensure all persons have left the blast area, and to understand safe job procedures for elimination of the hazards before beginning work.
  • Maintain and use all available methods of communication, such as sirens and radios, to warn persons of an impending blast. Establish methods to ensure that all persons are out of the blast area.
  • Before firing a blast give ample warning to allow all persons to be evacuated.
  • Guard or barricade all access routes to the blast area to prevent the passage of persons or vehicles.
  • Verify that the blasting procedures are effective and being followed at all times.

  • When descending a grade, operate the forklift with the load in the upgrade position.
  • Maintain control of self-propelled mobile equipment while it is in motion.
  • Operating speeds shall be consistent with conditions of roadways, tracks, grades, clearance, visibility, curves, and traffic.
  • Operate equipment within its designed limitations. Slow down or drop to a lower gear when necessary. Post areas where lower speeds are warranted.
  • Always wear a seat belt when operating self-propelled mobile equipment.

On June 21, 2012, a 49-year old customer truck driver with no mining experience was killed at a surface stone mine. He was driving a loaded dump truck, traveling down a grade, when the truck lost its brakes and went out of control. The victim jumped out and the truck ran over him. A passenger in the truck also jumped out and was treated at a hospital and released.

  • Ensure that mobile equipment operators are task trained adequately and demonstrate proficiency in all phases of mobile equipment operation before performing work.
  • Maintain equipment braking systems in good repair and adjustment.
  • Conduct adequate pre-operational checks to ensure the service brakes will stop and hold the mobile equipment prior to operating.
  • Know the truck’s capabilities, operating ranges, load-limits and safety features.
  • 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.
  • Slow down or shift to a lower gear when necessary. Post areas where lower speeds are warranted.
  • Always wear a seat belt when operating self-propelled mobile equipment.
  • Do not attempt to exit or jump from moving mobile equipment.
  • Provide adequate site specific hazard training to all customer truck drivers.
