Fatality #8

On May 18, 2019, a 34-year-old plant operator with 8 years of experience received fatal injuries when he was ejected from a man lift basket. The victim was tramming while elevated at 28 feet. The miner was wearing a fall protection harness with a retractable lanyard but it was not secured/tied off to the man lift basket. 

Best Practices: 

  • Always stay connected/tie off.  Always attach the lanyard of the approved fall protection device to the designated attachment point.
  • Use boom functions instead of tram functions to position the platform close to obstacles.
  • Ensure that persons are properly task trained regarding safe operating procedures before allowing them to operate mobile equipment.
  • Do not place yourself in a position that will expose you to hazards while performing a task.
  • Ensure that access gates or openings are closed.

2019 Fatality #7

On May 13, 2019, a 57-year-old truck driver with 12 years of experience was fatally injured when his haul truck rolled over. The haul truck was ascending a haul road when it slowed, stopped, and rolled backwards over 300 feet. The haul truck then ran up a hill, which caused it to roll over.

Best Practices: 

  • Task train mobile equipment operators adequately and ensure each operator can demonstrate proficiency in all phases of mobile equipment operation before performing work.
  • Conduct adequate pre-operational checks and correct any defects affecting safety in a timely manner prior to operating mobile equipment.
  • Maintain control of self-propelled mobile equipment while it is in motion.
  • Load trucks within the safe operating range based on the load rating of the truck, the road grade, and weather conditions.
  • Exercise caution when approaching grades and operate mobile equipment at speeds consistent with the conditions of roadways, tracks, grades, clearance, visibility, curves, and traffic.
  • Maintain equipment in accordance with manufacturer’s service and maintenance schedules.

Rescission Date:  June 26, 2019

The Acting Chair of MSHA’s Chargeability Review Committee reviewed the death certificate, autopsy report, and MSHA’s accident investigation findings and determined that the miner died from natural causes.  The  fatality is not chargeable to the mining industry.

[Since MSHA in their infinite wisdom is no longer counting MNM vs. Coal that confuses the number on every fatality for 2019 after this. I have attempted to go back and change those already posted so they correspond to the numbers MSHA references, but you may notice some text within the fatalgram that references old numbers. – Randy]

On March 7, 2019, a 46-year-contractor with three years of experience was fatally injured when he lost his balance and fell backwards through a narrow gap between two log washers and landed on a cable tray approximately 12 feet below.  The victim was changing drive belts on a log washer motor when his wrench slipped off of a bolt he was tightening, causing the loss of balance.

Best Practices: 

  • Always use fall protection equipment, safety belts and lines, when working at heights and near openings where there is a danger of falling.
  • Always be aware of your surroundings and any hazards that may be present.
  • Have properly designed handrails, guards, and covers securely in place at openings through which persons may fall.
  • Train personnel in safe work procedures regarding the use of handrails and fall protection equipment during maintenance and construction activities and ensure their use.
  • Conduct workplace examinations in order to identify and correct hazards prior to performing work.

On March 6, 2019, a 35-year-old contractor with 35 weeks of experience was fatally injured when he was struck by a relief valve that was ejected from a 500-ton hydraulic jack.    The hydraulic jack was being engaged to make contact with the frame of a P&H 4100A shovel when the relief valve was ejected.

Best Practices: 

  • Inspect, examine, maintain, and evaluate all materials and system components used in the installation, replacement, or repair of pressurized systems to ensure they are suitable for use and meet minimum manufacturer’s specifications.
  • Test systems at lower pressures to verify connections and flow rates prior to full pressure use.
  • Position yourself in a safe location, away from any potential sources of failure, while pressurizing systems.   
  • Consult and follow the manufacturer’s recommended safe work procedures.
  • Establish and discuss safe work procedures that include hazard analysis before beginning work. Identify and control all hazards associated with the work to be performed and use methods to properly protect persons.

On November 11, 2018, a 45-year old Underground Technician with 4 years of experience was killed when the Load-Haul-Dump (LHD) machine he had been operating underground ran over him.

Best Practices

  • Ensure that all braking systems installed on mobile equipment function properly when the engine is operating and when it is shut off.  Do not depend on hydraulic systems to hold mobile equipment in a stationary position
  • Block LHDs against motion by setting the parking brake. Turn the tires toward the rib and lower the bucket onto the floor.  Use wheel chocks when parking mobile equipment.
  • Conduct adequate pre-operational examinations on all self-propelled mobile equipment and promptly correct any defects affecting safety.
  • Before beginning a task, miners should discuss the work procedures, identify all possible hazards, and ensure steps are taken to safely perform the task.

On November 3, 2018, a 44-year old shift supervisor with 3 years of experience was killed when a loaded Caterpillar 785B haul truck ran over her pickup truck at the crusher site.

Best Practices

  • Communicate and verify with all equipment operators your planned movements and location upon entering a work area.
  • Ensure all persons are trained to recognize workplace hazards. Specifically, train equipment operators on the limited visibility and blind spot areas that are inherent to the operation of large equipment. Do not drive or park smaller vehicles in mobile equipment’s potential path of movement.
  • Instruct all operators on the importance of using flags or strobe lights on the cabs of their vehicles to make haulage truck operators aware of their location.
  • Install and maintain collision avoidance/warning technologies on mobile equipment.

On October 25, 2018, a 42-year old miner with 13 years of experience was killed when the back fell while he was loading explosives in the face.  The back was comprised of cemented backfill and weighed approximately 150 tons.

Best Practices

  • Implement a robust quality control program to ensure cemented rock fill is mixed and placed properly, especially when it constitutes the main method of ground support.
  • Examine and test ground conditions in areas where work is to be performed prior to work commencing and as warranted during the shift.  Be alert for changing conditions, especially after activities that could cause back/roof disturbance.
  • When ground conditions create a hazard to persons, install additional ground support before other work is permitted in the affected area.
  • Task train all persons to recognize all potentially hazardous conditions and ensure they understand safe job procedures for elimination of the hazards.
