MNM Fatality – 5/2/20

renewcomerLeave a comment

On May 2, 2020, a miner entered a dredged sand and gravel bin through a lower access hatch to clear an obstruction. The miner was clearing the blockage with a bar when the material inside the bin fell and engulfed him.

Best Practices: 

  1. Lock-out, tag-out. Never enter a bin until the supply and discharge equipment is locked out.
  2. Train miners to recognize and safely remove all potential hazards before beginning work and when clearing blocked hoppers.
  3. Equip bins with mechanical devices such as vibrating shakers or air cannons to loosen blockages, or provide other effective means of handling material so miners are not exposed to entrapment hazards by falling or sliding material.
  4. Follow manufacturer recommendations for clearing out blockages.
  5. Establish and discuss policies and procedures for safely clearing bins.
  6. Install a heavy screen (grizzly) to control the size of the material and prevent clogging.

Additional Information: 

This is the 7th fatality reported in 2020, and the second classified as “Handling Material.”

An over-the-road truck driver was found unresponsive near his bulk trailer, where it appears he fell from the top of the trailer. The driver was taken to the hospital and underwent emergency surgery; however, he passed away from his injuries.

Best Practices: 

  1. Provide a means to align bulk trailers under truck racks to assure the ramp is aligned correctly with the trailer’s lids so that miners have safe access. Alignment methods can include painted lines, concrete barriers, cameras and monitors, or sensors to indicate proper positioning.
  2. Wear proper footwear that is clean and in good condition.
  3. Examine work areas and routinely monitor work habits to ensure that workers follow safe work procedures.
  4. Identify and control all hazards associated with the work to be performed.

On August 27, 2019 a miner was splitting and sorting rock in a quarry when lightning was observed in the distance. The miner was seeking shelter when he was struck by lightning.

Best Practices: 

  1. Train miners to take action after hearing thunder, seeing lightning, or perceiving any other warning signs of approaching thunderstorms.
  2. Use the established emergency communications system to provide miners with warnings when lightning is in the area.
  3. Identify locations for substantially built safe lightning shelters.
  4. Stay in safe shelter at least 30 minutes after the last sound of thunder.

Francis E. Tatro, a 69-year-old front-end loader operator with over 37 years of total mining experience, died from aspiration pneumonia on January 8, 2020.  Tatro suffered injuries and hospitalization as a result of an accident on July 30, 2019.  Tatro was operating a front-end loader when the front-end loader’s bucket contacted the ground, causing the front-end loader to abruptly stop. The force of the impact resulted in Tatro, who was not wearing a seat belt, striking the front window, which caused serious injury, including paralysis to the arms and legs. 

Best Practices: 

1. Always wear seat belts when operating mobile equipment.
2. Maintain control and stay alert when operating mobile equipment.
3. Know the hazards. Be certain anyone operating front-end loaders is aware of safe operating practices and potential hazards.

On February 27, 2020, a miner died when an unsecured 20’x8’x1″ steel plate standing on edge fell and struck him. The steel plate was being used to cover the end of a feeder to allow an equipment operator to build an earthen ramp to the feeder.

Best Practices: 

  • Establish and discuss safe work procedures before beginning work.
  • Identify and control all hazards.
  • Task train everyone on safe job procedures and to stay clear of suspended loads.
  • Require all workers to stay out of the fall path of heavy objects/materials that have the potential of becoming off-balance while in a raised position.
  • Monitor routinely to confirm safe work procedures are followed.
  • Be aware of your environment. Factors such as wind, snow, and icy surfaces can affect the stability of an object.
  • When securing an object, identify the location of its center of gravity.

On February 27, 2020, a trucking company employee died while helping to position a low-boy trailer.  The victim was standing in front of the trailer wheels to assist the driver.  The truck driver moved the truck forward causing the wheels of the trailer to strike the victim.

Best Practices: 

  • Communicate your planned movements with the equipment operator before approaching mobile equipment and verify the information was received and understood.
  • Verify miners are clear before driving mobile equipment. Communicate your planned movements with miners and verify the information was received and understood.
  • Sound your horn to warn miners that you are about to move and wait to give them time to get to a safe location.
  • Establish policies and procedures for miners to stand in safe locations when directing mobile equipment.
  • Inspect backup alarms and collision warning/avoidance systems on mobile equipment to ensure they are maintained and operational.
  • Wear high visibility clothing when working around mobile equipment.

On February 29, 2020, a plant foreman was priming the main suction pump on a dredge when a two-inch coupling on the waterjet pipe failed, knocking the victim into the water. Divers retrieved his body several hours later. The victim was not wearing a life preserver.

Best Practices: 

  • Wear a life preserver where there is a risk of falling into the water.
  • Identify all possible hazards and ensure appropriate controls are in place to protect miners before beginning work.
  • Provide swimming training for everyone that works around water.

MNM Fatality – 1/8/20

A miner fell into a portable load out bin on January 8, 2020, and died at the scene.

Best Practices: 

  1. Check handrails and gates. Ensure handrails and gates are substantially constructed, properly secured, and free of defects.
  2. Install mechanical flow-enhancing devices so workers do not have to enter a bin to start or maintain material flow.
  3. Don’t stand on material stored in bins. Material stored in a bin can bridge over the hopper outlet, creating a hidden void below the material surface.
  4. Lock-out, tag-out. Do not enter a bin until the supply and discharge equipment is locked out.
  5. Wear a safety belt or harness secured with a lanyard to an adequate anchor point before entering a bin. Station a second person near the anchor point to make sure there’s no slack in the fall protection system.
  6. Train all miners to recognize fall hazards and properly use fall protection.
  7. Provide safe access to all work places, and discuss and establish safe work procedures.

  2. Post warning signs or barricades to keep miners out of areas where health or safety hazards exist.
  3. Install an audible alarm to warn of impending equipment movement.
  4. Evaluate and correct possible hazards promptly before working.
  5. Train personnel in safely using handrails and fall protection equipment during maintenance and construction activities. Ensure their use.

While spotting for a dump truck, a contractor stepped directly into the path of a bulldozer and died at the scene on November 16, 2019.

Best Practices: 

  1. Safety first. Before starting work, establish and discuss safe work procedures. Identify and control all hazards associated with the work and properly protect workers.
  2. Know where people are. Be aware of body positioning around equipment, traffic patterns, dump sites, and haul roads.
  3. Train miners and contractors on traffic controls, mobile equipment patterns, and other site-specific hazards.
  4. Stay alert. Do not place yourself in harm’s way.
  5. Communicate with mobile equipment operators and ensure they acknowledge your presence.
  6. Ensure travelways are clear before moving a vehicle or mobile equipment.
  7. Look behind you. Install “rear viewing” cameras or other collision warning systems on mobile equipment. When backing up, look over your shoulder to eliminate blind spots. When using mirrors, use all available mirrors.
  8. Wear reflective material while working around mobile equipment. Use flags, visible to equipment operators, to make miners and smaller vehicles more visible.
