Fatality #15 for Metal/Nonmetal Mining 2011

renewcomerLeave a comment

On December 8, 2011, a 41 year-old crusher operator with 8 years of experience was killed at a surface stone operation. A set of wheels was to be placed on a conveyor to transport it from the mine. A front-end loader was being used to lift the conveyor when the loader bucket suddenly dropped, allowing the frame of the conveyor to strike one of the tire assemblies. The tire assembly then shifted, striking the victim.

Best Practices

  • Inspect mobile equipment before placing it in operation for the shift.
  • Correct safety defects on equipment in a timely manner to prevent the creation of a hazard to persons.
  • Establish safe work procedures and identify and remove hazards before beginning a task.
  • Ensure that persons are task-trained and understand the hazards associated with the work being performed.
  • Do not place yourself in a position that will expose you to hazards while performing a task.
  • Monitor personnel routinely to determine that safe work procedures are followed.

On Friday, October 28, 2011, a 47-year old lead blaster and 23-year old blaster helper were killed when the 1-ton truck they were riding was struck and completely covered by fallen rock from a failed highwall. The victims were driving in the pit, past a trackhoe loading coal as they approached their work area. The rock reached approximately 80′ across the 100′ wide pit and struck the trackhoe and a haulage vehicle being loaded at the time of the accident.

Best Practices

  • Train all miners to recognize hazardous highwall conditions.
  • Look, Listen and Evaluate your highwall and pit conditions daily, especially after each rain, freeze, or thaw.
  • Be your own examiner and find hazards before they find you.
  • Maintain adequate lighting to aid in examinations of highwalls and pit during no light or low light situations.
  • Observe and communicate highwall hazards immediately.
  • Insure appropriate action is taken to remove the hazards associated with any anomaly that may appear in the highwall or pit.
  • Ensure that personnel’s work or travel areas and mining systems or equipment are operating are a safe distance from the toe of the highwall.
  • Follow safe job procedures.

Fatality #14 for Metal/Nonmetal Mining 2011

On November 17, 2011, a 26 year-old contract underground miner with 3½ years of experience was seriously injured in a silver mine. He died at a hospital on November 19, 2011. The victim and a coworker were attempting to dislodge muck in a bin excavation when the muck they were standing on started to flow. The victim was wearing a safety harness attached to a self-retracting lanyard; however, the lanyard extended and did not lock before he became engulfed. The other miner was freed immediately, treated, and released from the hospital.

Best Practices
 

  • Wear a safety harness and attach it to a securely anchored lanyard, where there is a danger of falling.
  • In applications where the danger is not limited to a free-fall, do not use lanyards that depend on free-fall speed to lock. Follow the manufacturer’s recommendations.
  • Ensure that persons working on material in bins, silos, hoppers, tanks, and surge piles are properly tied-off, with one line tender per person. No persons should enter the facility until the supply and discharge equipment are locked out.
  • Establish policies and procedures for safely clearing muck in a bin excavation and ensure that persons follow these safe procedures.
  • Ensure that persons are task-trained and understand the hazards associated with the work being performed and the proper use of their personal protective equipment.

On November 7, 2011, an 82 year-old owner/crusher operator with 27 years of experience was killed at a surface crushed stone operation. The victim was attempting to dislodge material from the vibrating feed hopper when he slipped or fell into the operating jaw crusher.

Best Practices

  • Establish policies and procedures for safely clearing plugged material in a feed hopper. Evaluate design modifications or use auxiliary equipment to reduce the risks associated with clearing an obstruction.
  • Ensure that persons are task trained and understand the hazards associated with the work being performed.
  • Deenergize and Lock-out/tag-out all power sources before working on crushers.
  • Provide and maintain a safe means of access to all working places.

Fatality #17 for Coal Mining 2011

renewcomerLeave a comment

On Monday, October 17, 2011, a 62-year old miner was killed on the surface of the underground mine while using a jumper cable to move a track-mounted back hoe machine at a gap in the trolley wire. When reenergized by a jumper cable, the machine struck and ran over him. The victim had 30 years of mining experience, with one day of experience operating this machine.

Best Practices

  • Assure all tram control switches are in the off position and the brake is set before applying a DC power jumper to the machine.
  • Always attach a nip on the machine first, then attach the nip on trolley wire, while standing in a safe location.
  • Ensure adequate task training is provided to equipment operators which cover all machine controls, functions and hazards related to the machine operation and any safe operating procedures related to the specific equipment operation.
  • Use self-centering tram/power controls to limit unexpected machine movement.
