Fatality #11 for Metal/Nonmetal Mining 2018

renewcomerLeave a comment

On October 11, 2018, a 26-year old miner with 48 weeks of experience at the mine was fatally injured as a result of falling from on top of a previously cut block of granite.  The victim was in the process of separating the cut block of granite from the highwall when the cut block suddenly slid out.  The movement caused the miner, who was not wearing fall protection, to lose his balance and fall between the rock and the highwall causing fatal injuries.

Best Practices

  • Install fall protection systems that allow safe movement to perform work.
  • Always conduct examinations of working places in order to identify loose ground or unstable conditions before work begins and as changing ground conditions warrant.
  • Ensure that the person conducting the examination has the training and experience to recognize potential hazards.
  • Discuss work procedures and identify all hazards associated with working near highwalls along with the methods to protect personnel.
  • Do not place yourself in a position that will expose you to hazards while performing work tasks.

On October 2, 2018, a 40-year old miner with 20 years of experience was fatally injured when struck by stemming sand ejected from a borehole.  While conducting a blasting operation in a new vertical raise, a contract foreman was attempting to clean out a previously blasted vertical borehole with high-pressure air.  A sudden release of energy forced stemming sand from the bottom of the borehole, striking the miner.

Best Practices

  • Assess the suitability of blasting methods when blasts do not perform as intended.
  • Use water to clean out the bottom of boreholes used for blasting.
  • Never position yourself directly over or in front of the collar of a borehole when cleaning it out.
  • Ensure miners are adequately task trained.

On August 22, 2018, a 29-year old miner with 1 year of experience was fatally injured while cleaning a snub pulley.  The victim was working from an aerial lift located under the belt conveyor when he became entangled in the conveyor pulley.

Best Practices

  • Ensure that persons assigned to clean conveyor belts have received adequate training and verify that safe belt conveyor work practices are followed.
  • Stay clear of moving equipment and do not reach into any part of a moving conveyor.
  • Avoid wearing loose-fitting clothing when working around moving conveyor belt components.
  • Verify that all incoming power connectors are open by a circuit breaker, the conveyor is stopped and secured from movement before working on belt conveyors.
  • Provide and maintain safe access to elevated areas where routine maintenance is performed.

On July 31, 2018, a 62-year old foreman with 40 years of experience, was fatally injured while dismantling a portable crusher. The front-end loader was placing a 20-foot long steel tube onto the screen feed conveyor. The front-end loader operator lowered the bucket and crushed the victim against the conveyor structure.

Best Practices

  • Front-end loader operators must ensure personnel are not near the machine when in operation.
  • Use cranes with appropriate rigging and tag lines to position components.
  • When working near equipment, make eye contact with the equipment operator and directly communicate your intended movements.
  • Wear a reflective vest or clothing while working.
  • Ensure all persons are trained to recognize workplace hazards – specifically, the limited visibility and blind areas inherent to operation of large equipment.
  • Prior to starting the task, train miners on proper maintenance procedures and discuss steps that will be taken to safely perform the job.

On June 23, 2018, a 46-year old electrician with 10 weeks of experience was fatally injured while trying to stop runaway railcars.  The miner ran to the front of a set of moving railcars and jumped on in order to set the hand brake.  The miner then attempted to jump clear and was fatally injured when he was run over by the moving railcars.

Best Practices

  • Apply a mechanical hand brake to ensure a railcar does not move when it is stopped for loading, unloading, or storage.  Use wheel chocks or derail devices for added protection against accidental movement.
  • Never attempt to mount, crossover, cross under, or dismount a railcar while it is moving.
  • Train personnel in the safe procedures of working with railcars.  Establish safe work procedures and ensure all personnel involved communicate clearly with each other.

On June 13, 2018, a 65-year old truck driver with 4 years of experience was fatally injured when his truck traveled over a berm and into an impoundment of water.  Divers recovered the victim in 20 feet of water.

Best Practices

  • Maintain control and stay alert when operating mobile equipment.
  • Conduct adequate pre-operational checks and correct any defects affecting safety in a timely manner prior to operating mobile equipment. Maintain equipment braking and steering systems in good repair and adjustment.
  • Operate mobile equipment at speeds consistent with the conditions of roadways, tracks, grades, clearance, visibility, curves, and traffic.
  • Ensure that berms are adequate for the vehicles present on site, including but not limited to height, material, and built on firm ground.
  • Consider storing personal flotation devices in equipment that is being operated near water.
  • Ensure that all exits from cabs on mobile equipment, including alternate and emergency exits, are maintained and operable.
  • Use seat belts when operating mobile equipment.

On May 9, 2018, a 27-year old kiln technician with 32 weeks of experience was burned while lighting a gas fired kiln. There was a blow back when igniting the kiln and the miner received burn injuries to his head and chest.  The miner succumbed to his injuries on May 28, 2018.

Best Practices

  • Remove flammable and combustible materials from areas prior to cutting, welding, or other hot work. A qualified person should monitor nearby areas where heavy vapors could migrate and accumulate.
  • Ventilation systems should be properly designed, installed, and maintained.
  • Install fixed monitoring systems with alarms in areas with potential for flammable and other hazardous atmospheres and calibrate and maintain them regularly.  The systems should have redundant controls and system readouts located inside and outside of hazardous areas.
  • Process equipment and systems should be properly designed and completely installed prior to use.
  • Inerting systems should be properly designed, installed, adequately filled, and maintained.
  • Do not work in areas where concentrations of vapors can be immediately fatal (Lower Explosive Limit), Immediately Dangerous to Life or Health, or where they exceed permissible exposure limits (PELs) to produce adverse health effects.
  • Minimize or eliminate hazards by using appropriate engineering and administrative controls.

On April 12, 2018, a 60-year old customer truck driver was killed when he fell from, and was run over by, his truck while scanning into the operator’s check-in system.  The victim was found underneath the belly dump of the semi-trailer, and the truck was still in gear.

Best Practices

  • Implement check-in system technology that can be scanned remotely from inside the vehicle such as a RFID tag or indicator.
  • Commercial and customer truck drivers should remain in their trucks while on mine property, unless a safe area for tarping and checking their loads has been designated.
  • Operators should place their equipment in neutral and set the parking brakes before exiting the operator compartment.
  • Rules establishing safe operating procedures should be posted.
  • Ensure workers who operate heavy equipment are adequately informed, instructed, trained and supervised.

  • Carefully inspect all rigging prior to each use.
  • Train persons to recognize and control all hazards associated with performing repair or maintenance tasks.
  • Persons should communicate during maintenance tasks with each other.
  • Position yourself only in areas where you will not be exposed to hazards resulting from a sudden release of energy.
  • Attach taglines to loads that may require steadying or guidance while suspended. Stand clear of items of massive weights having the potential of becoming off-balanced while being loaded or unloaded
  • Assign a sufficient number of persons to repair or maintenance tasks to ensure the tasks can be safely performed.
  • Do not place yourself in a position that will expose you to hazards while performing repair or maintenance tasks.
  • Miners should wear fall protection when working at elevated heights.
