renewcomerLeave a comment

ftl2013m09On June 13, 2013, a 50-year old mechanic with 15 years of experience was killed at a stone operation. He was operating a 35 ton articulated haul truck down a haul road. The truck went out of control and hit a berm, propelling it in the air. The truck came to a stop with the bed overturned and the cab upright. The victim was ejected from the truck.

Best Practices

  • 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.

ftl2013m08On June 2, 2013, a 42-year old miner with 2½ years of experience was killed at an underground gold mine. The victim was operating a Load Haul Dump (LHD), preparing to backfill a stope, when the LHD overtraveled the edge of the stope and fell into the open hole.

Best Practices

  • Establish policies and procedures for conducting specific tasks.
  • Before beginning any work, ensure that persons are properly task trained and understand the hazards associated with the work to be performed.
  • Provide berms, bumper blocks, safety hooks or similar impeding devices at dumping locations where there is a hazard of overtravel or overturning.

Fatality #9 for Coal Mining 2013

ftl2013c09On Thursday, June 6, 2013, a 36-year-old conveyor belt foreman with 4 years of mining experience was killed while checking a belt wiper at the belt conveyor discharge. He was positioned at the end of an elevated catwalk parallel to the belt drive to check the wiper. When the victim contacted the guardrail at the end of the catwalk, it gave way and he fell below onto the moving belt conveyor.

Best Practices

  • Check guards along belt conveyors for stability and good repair.
  • Train all employees thoroughly on the dangers of working or traveling around moving conveyor belts.
  • Install appropriately-designed railings, barriers, or covers at all required conveyor belt locations, and ensure it is maintained in structurally sound condition.
  • Perform thorough workplace examinations. Inspect the work areas for all potential hazards including places that persons may fall from or through.
  • Provide belt conveyor stop and start controls at areas where miners must access both sides of the conveyor. Provide these areas with adequate crossing facilities (e.g. cross-overs or cross-unders).
  • Do not assume handrails or guards are strong enough to support you, and never lean against or support your weight on guarding.

On May 17, 2013, a 22-year old mucker with 31 weeks of experience was killed at an underground molybdenum mine. The victim was checking a derailed loaded ore car when he was pinned between it and another loaded ore car.

Best Practices

  • Establish policies and procedures for conducting specific tasks.
  • Before beginning any work, ensure that persons are properly task trained and understand the hazards associated with the work to be performed.
  • Maintain communications with all persons performing the task.
  • Conduct adequate pre-operational checks and ensure that all braking systems on mobile equipment are functioning properly.
  • Do not work or cross between rail cars unless the locomotive is stopped and the operator is notified and acknowledges your presence.
  • Never place yourself between rail cars without blocking them to prevent movement.
  • Maintain the track and track mounted equipment to prevent derails.

ftl2013m06On April 27, 2013, a 58-year old mechanic with 2 years of experience was killed at a surface gypsum operation. The victim was clearing a blockage on a mobile track-mounted crusher when he became entangled in the discharge conveyor.

Best Practices

  • Establish policies and procedures for conducting specific tasks on belt conveyors.
  • Before beginning any work, ensure that persons are task trained and understand the hazards associated with the work to be performed.
  • Do not perform work on a belt conveyor until the power is off, locked, and tagged, and machinery components are blocked against motion.
  • Provide emergency stop mechanisms at the control panel(s) and at ground level where maintenance or repair work is performed.
  • Provide appropriate controls to protect any person working near a stalled conveyor from unexpected motion.
  • Maintain communications with all persons performing the task. Before starting belt conveyors, ensure that all persons are clear.

Fatality #5 for Metal/Nonmetal Mining 2013

renewcomerLeave a comment

ftl2013m05On April 16, 2013, a 58-year old shaftman with 32 years of experience was seriously injured at an underground salt mine. The victim and two coworkers were replacing a bushing on the side of a skip hoist in the production shaft. The victim was standing on a steel beam outside the handrails of a covered work platform where the coworkers were standing, when a piece of salt fell and struck him. He was transported to a hospital where he died on April 17, 2013.

Best Practices

  • Establish and discuss safe work procedures. Identify and control all hazards associated with the work to be performed in a shaft with the methods to properly protect persons.
  • Task train all persons to recognize all potential hazardous conditions and to understand safe job procedures for elimination of the hazards, such as falling material, before beginning work.
  • Examine the shaft and remove loose material prior to commencing work.
  • Implement measures to ensure persons are properly positioned and protected from falling material while performing shaft maintenance work.
  • Perform shaft maintenance work from a substantial platform with adequate overhead protection.
  • Perform maintenance work for skip hoists and other conveyances on the surface whenever possible.
  • Monitor personnel routinely to determine that safe work procedures are followed.
