Fatality #1 for Coal Mining 2012

renewcomerLeave a comment


On January 18, 2012, a 44-year-old utility/diesel tram operator with 1 year and 8 months mining experience, died from injuries he received on January 11, 2012. The miner was repairing a damaged water outlet (fire valve manifold) when a 1.5 inch bronze ball valve (quarter turn valve) catastrophically failed, propelling the steel manifold into the miner’s face/head. This fire valve manifold was originally damaged when an oversized load being transported on the adjacent mine track haulage system contacted the outlet causing it to separate from the 6″ mine water supply. The failure resulted from the internal threaded body of the valve separating from the external threaded portion of the valve.

Best Practices

  • When performing work on pressurized water supply piping systems, STOP ALL water flow into the pipe being worked on; BLEED ALL residual pressure from the pipeline, and when possible, OPEN A VALVE at an alternate location to ensure constant pressure relief. LOCK OUT and TAG OUT these valves to ensure safety while repairs are made.
  • NEVER REUSE components in a pressurized line that may have been damaged or compromised.
  • Ensure that components, such as valves, couplings etc. used in a pressurized water system are compatible with the highest measured or expected STATIC pressure in the system.
  • Implement a Standard Operating Procedure for the design, installation, testing, and maintenance of pressurized fluid systems that is consistent with National Fire Protection Association (NFPA) standards.
  • Install slow closing indicating valves. When opening a valve to put water flow into a pressurized system, do it slowly and minimize your exposure to pressurized components. See slow closing indicating valves on MSHA’s Belt Fire Suppression Simulator at the National Mine Health and Safety Academy. http://www.msha.gov/alerts/SafetyFlyers/ScoreaTDMineFire2009.pdf
  • Inspect, examine, and evaluate all materials that are being used during installation, replacement, or repair of pressurized water systems to ensure suitability.
  • Properly train all miners on the hazards associated with working on or around pressurized fluid piping systems.
  • Maintain safe and adequate clearance to prevent mobile equipment and machinery from contacting pressurized lines, valves, etc.
  • Install barriers to prevent equipment from damaging piping and valves.
  • Ensure adequate supervision is in place when moving oversized equipment in haulage entries.

Fatality #2 for Metal/Nonmetal Mining 2012

renewcomerLeave a comment

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.

Fatality #23 for Coal Mining 2011

renewcomerLeave a comment

On Wednesday, December 7, 2011, at approximately 7:30 a.m., a 49-year-old excavator operator, with 20 years of mining experience, was fatally injured when a highwall he was working near collapsed. The excavator was being used to load rock trucks. The operator’s cab was positioned on the highwall side when the accident occurred.

Best Practices

  • Operate excavators with the cab perpendicular to, and away from, the highwall.
  • Design benches to safely accommodate the type of equipment used and include this in the Ground Control Plan.
  • Examine highwalls from as many perspectives as possible (bottom, sides, and top/crest) while maintaining the safety of the examiner(s). Look for signs of cracking or other geologic discontinuities.
  • 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 during inclement weather.
  • Immediately remove all personnel exposed to hazardous ground conditions, barricade, and/or post signs to prevent entry, and promptly correct the unsafe conditions.
  • Brief foremen and miners coming to work on any uncorrected hazardous conditions, and ensure the hazardous conditions are noted in the on-shift examination record book.

February 2012 Impact Inspections

renewcomerLeave a comment

The U.S. Department of Labor’s Mine Safety and Health Administration announced that federal inspectors issued 253 citations and orders during special impact inspections conducted at 15 coal mines and two metal/nonmetal mines last month. The coal mines were issued 235 citations and eightorders, while the metal/nonmetal operations were issued 23 citations and six orders.

Fatality #1 for Metal/Nonmetal Mining 2012

renewcomerLeave a comment

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 #22 for Coal Mining 2011

renewcomerLeave a comment

On Saturday, December 3, 2011, at approximately 8:35 a.m., a bulldozer operator with 18 years of mining experience was seriously injured when the bulldozer he was operating travelled over a highwall and fell approximately 90 feet to the pit below. The victim was in the process of clearing topsoil from the bench in preparation for the next blast. The victim was not wearing a seatbelt and was ejected from the bulldozer. The victim died on December 6, 2011, from the injuries sustained in this accident.

Best Practices

  • Ensure the ground control plan is adequate for the mining conditions.
  • Perform examinations of ground conditions, and perform additional checks during the work shift to ensure ground conditions have not changed.
  • Mark the limits of travel with pylons or reflectors.
  • Be aware of your location and proximity to the highwall. When operating a bulldozer close to an edge, always keep the blade between you and the edge. Bulldozer operators should not operate their machines parallel to the edge of highwalls.
  • Use a spotter to warn equipment operators when they approach the edge of a highwall.
  • Ensure seat belts are provided, maintained, and worn at all times.
  • Never jump out of equipment.
  • Visit MSHA’s Safety Target Single Source Page for additional safety information concerning bulldozers.
