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.

  • Review and discuss MSDS control section recommendations. Establish and discuss safe work procedures before starting any work and identify and control all hazards.
  • Train all persons to recognize and understand safe job procedures, including the physical and health hazards of chemicals that are being used and the proper use of respiratory protection.
  • Ensure that adequate exhaust ventilation is provided to all work areas.
  • Ensure that persons are not required to perform work alone in any area where hazardous conditions exist that would endanger their safety.

On September 13, 2011, a 38 year-old miner with 3 years of experience was killed at a portable sand and gravel operation. The victim opened the 480 volt feeder box at the motor control center and started to remove the leads when he received a fatal shock.

Best Practices

  • Be trained on all the electrical tests and safety equipment necessary to safely test and ground the circuit being worked on.
  • Conduct a risk assessment.
  • Use properly rated Personal Protective Equipment (PPE) including Arc Flash Protection such as a hood, gloves, shirt, and pants.
  • Positively identify the circuit on which work is to be conducted.
  • De-energize power and ensure that the circuit is visibly open.
  • Place YOUR lock and tag on the disconnecting device.
  • Verify the circuit is de-energized by testing for voltage using properly rated test equipment.
  • Ensure ALL electrical components in the enclosure are de-energized.
  • Ground ALL phase conductors to the equipment grounding medium with grounding equipment that is properly rated.

On Thursday September 1, 2011, a 29-year-old contract driller with 1 year, 3 months of experience was killed at a surface coal mine. The victim was attempting to separate a pipe connection when he was struck by a tong wrench. The rig was being used to drill a water well. The crew was working to free the drill stem that was stuck in the drill hole when the accident occurred.

Best Practices
  • Stand a safe distance from areas of potential high energy release.
  • Know the radius of machinery that pivots.
  • Establish and follow safe work procedures.
  • Ensure all components are adequately blocked and secured to prevent unintended motion.
  • Know the limitations of equipment used for blocking motion and ensure that they are used within their specified limitations.
  • Ensure all components are in good repair.
  • Establish and follow communication procedures.

Fatality #12 for Coal Mining 2011

On Wednesday, July 27, 2011, a 39-year-old miner with 22 years of mining experience was electrocuted while welding to connect two pipes together. He was working in the ceiling of the filter room of a preparation plant. This area, where the welding was being conducted, was wet and the illumination was limited. The victim contacted an energized welding electrode.

Best Practices

  • Do not touch an energized electrode with bare skin.
  • Avoid wet working conditions. A person’s perspiration can lower the body’s resistance to electrical shock. Do not drape electrode wires or leads over your body.
  • Work in a confined space only if it is well ventilated and illuminated.
  • Do not use the plant structure as the work (return) conductor. Connect the work cable (return) as close to the welding area as practical to prevent welding current from traveling unknown paths and causing possible shock, spark, and fire hazards.
  • Insulate yourself from work and ground by using and/or wearing dry insulating mats, covers, clothes, footwear, and gloves. Inspect welding gloves for damage prior to welding and ensure the gloves are dry.
  • Use only well maintained equipment. Frequently inspect welding wires or leads for damaged or exposed conductors. Replace or repair wires or leads immediately if damaged.
  • Use voltage reduction safety devices (if available) for arc welders.

On Thursday, July 21, 2011, at approximately 9:05 p.m., an office worker was killed at a surface coal operation when she was struck by a pickup driven by a vendor. As part of a wellness program instituted at the mine, the victim was walking along a rural road on the permit area for the mine when the pickup struck her from behind. The vendor was accessing the mine for routine maintenance.

Best Practices

  • Maintain complete control over vehicles and equipment while in operation.
  • Stay alert for unexpected pedestrians when driving in rural areas.
  • Drive at speeds relative to changing light and conditions.
  • Walk in designated pedestrian areas or facing traffic.
  • Wear highly visible reflective clothing when walking on roadways.
  • Ensure there is no oncoming traffic when crossing roadways.
  • Post signs and appropriate speed limits in areas where pedestrians may be present.

On Thursday, June 9, 2011, a 53 year-old contract steelworker, with over 16 years of coal mine experience, was killed when he fell approximately 8 feet from a steel beam. He hit a lower cross beam before he landed on a conveyor belt cover located about 32 inches below the cross beam. The victim had been engaged in cutting operations just prior to the fall, and was repositioning when he removed his lanyard tie-off safety device from the location where it was secured.
Best Practices

  • Wear and use fall protection, maintaining 100 per cent tie off, when fall hazards exist.
    See TieOff.asp
  • Ensure workers are trained and understand the proper use of restraint devices.
  • Provide self retracting lanyard mechanisms when possible.
  • Ensure secure footing in all work areas.
  • Examine tools and personal protective equipment routinely and replace when defects or wear is evident.
  • Conduct a risk assessment of the work area prior to beginning any task and identify all possible hazards. Use the SLAM; Stop, Look, Analyze, and Manage approach for work place safety.

June 6, 2011
Powered Haulage – Surface – Virginia
Humphreys Enterprises Inc. – No 5 Strip
Based on MSHA’s investigation and the finding of the death certificate, MSHA concluded that the miner died from natural causes and that the fatality should be de-listed and not charged to the mining industry. The death certificate indicated that the death was natural and was due to a cardiac arrhythmia due to a myocardial infarction which in turn was due to coronary artery atherosclerosis.”

On Saturday, May 14, 2011, a 37-year old mechanic with 14 years of mining experience and 1½ years of experience as a mechanic, was killed while removing a counter weight fuel tank assembly from a front-end loader. He was positioned beneath the front-end loader when he removed 14 of the 16 mounting bolts that secure the counter weight. When the victim attempted to remove the next to last bolt, the remaining two bolts failed allowing the 11,685 pound counterweight to fall on him. The counter weight had not been blocked to prevent it from falling.

Best Practices
  • Install blocking materials before removing mounting bolts from machinery components which can fall during disassembly.
  • Follow known safe maintenance procedures.
  • Follow the equipment manufacturers recommended maintenance procedures when performing repairs to machinery.
  • Train new mechanics in the health and safety aspects and safe work procedures related to their assigned tasks.
