On February 22, 2012, a 46 year-old plant mechanic with 7 years of experience was injured at a crushed stone operation when he fell 16 feet from an elevated walkway of a conveyor to the ground below. The victim and a coworker had been bolting a snub pulley in position. The coworker was positioned on a walkway on the other side of the belt. The victim was hospitalized and died on February 26, 2012.

Best Practices 

  • Establish and discuss safe work procedures. Before starting any work, identify and control all hazards.
  • Train all persons to recognize and understand safe job procedures, including the proper use of fall protection.
  • Always use fall protection when working where a fall hazard exists.
  • Install railings or cables when persons are required to work or travel near the edge of a structure.

On February 14, 2012, a 40 year-old mine owner with 8 years of experience was killed at a shale operation. The victim was operating an excavator with a rock breaker attachment. He was breaking and mining material from a near vertical wall when the face fell onto the cab of the excavator, crushing him.

Best Practices

  • Operate excavators with the cab and tracks perpendicular to, and away from, the highwall.
  • Bench or slope the material to maintain stability and to safely accommodate the type of equipment used. Do not undercut material on the face of a slope, bank, or highwall.
  • Examine highwalls, slopes, and banks from as many perspectives as possible (bottom, sides, and top/crest) while maintaining the safety of the examiner(s). Look for signs of cracking, bulging, sliding, toppling or other signs of instability. Record the type and location of hazardous conditions.
  • Use auxiliary lighting during non-daylight hours to conduct highwall examinations and to illuminate active work areas.
  • Perform supplemental examinations of highwalls, banks, benches, and sloping terrain in the working area.
  • Immediately remove all personnel exposed to hazardous ground conditions and promptly correct the unsafe conditions. When the conditions can not be corrected, barricade and post signs to prevent entry.
  • Remove loose or overhanging material from the face. Correct hazardous conditions by working from a safe location.

On January 27, 2012, a 69 year-old mobile equipment operator with 48 years of experience was killed at a cement operation. The victim was cleaning a tailpiece with a skid steer loader. He backed the loader in a drainage ditch, traveled in reverse about 150 feet, and went into a 5½-foot deep water hole.

Best Practices

  • Ensure that persons are task trained and understand the hazards associated with the work being performed.
  • Equipment operators should be familiar with their working environment at all times.
  • Ensure that safety precautions are taken based on different weather and lighting conditions.
  • Keep mobile equipment a safe distance from the edge of water or embankments.
  • Barricade or post warning signs at all approaches in areas where health or safety hazards exist that are not immediately obvious to all persons. Warning signs shall be readily visible, legible, and display the nature of the hazard and any protective action required.
  • Provide and maintain berms or guardrails on the banks of roadways where a drop-off exists of sufficient grade or depth to cause a vehicle to overturn or endanger persons in equipment.
  • Monitor personnel’s work activities routinely to determine that safe work procedures are followed.
  • Operate equipment in a manner that maximizes visibility. Use a spotter when visibility of the work or travel areas is limited.

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.

Fatality #14 for Metal/Nonmetal Mining 2011

renewcomerLeave a comment

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.

On October 31, 2011, a 42 year-old muck haul leadman with 3½ years of experience was killed in an underground platinum mine. The victim was operating a 4-yard loader in a drift when the loader struck the left rib. At that time, a spieling (rebar anchored in the rib for ground control) that was protruding from the rib, penetrated the front side window, entered the cab, and struck him.

Best Practices

  •  Operators of self-propelled mobile equipment shall maintain control of the equipment while it is in motion.
  • Maintain all roadways free of materials that may pose a hazard to equipment operators. This includes materials on the floor and protruding from the ribs, back, or walls.
  • Operating speeds shall be consistent with conditions of roadways, tracks, grades, clearance, visibility, curves, and traffic.
  • Slow down or drop to a lower gear when necessary. Post areas where lower speeds are warranted.
  • Always wear a seat belt when operating self-propelled mobile equipment.
  • Trim protruding spielings.
  • Keep mobile equipment operator’s stations free of materials that can impair the safe operation of the equipment.
  • When clearances on roadways are restricted, install warning devices in advance of the area and conspicuously mark it.
