renewcomerLeave a comment

On Sunday, February 26, 2012, at 1:15 a.m., a 52-year-old deckhand with 4 years of mining experience was determined missing. He had been assigned the task of measuring the draft of a set of empty barges that were to be loaded. He had to cross from the dock to the first empty barge. Witnesses observed him on the empty barge walking up-river on the barge. He apparently fell from the barge into the water. Co-workers saw his cap in the water and immediately called for the rescue squad. The victim was found beneath the bow of the dock at approximately 2:30 a.m. The miner was wearing a flotation device, but the flotation device was not designed to keep an unconscious miner’s face above water.

Best Practices

  • Utilize electronic devices to determine the draft in barges.
  • Install and use lifeline tie-off systems to provide fall protection over water.
  • Utilize and maintain sufficient area lighting and personal lighting.
  • Set up a look out and communications protocol. Do not work alone.
  • Ensure safe access is provided where persons are required to work or travel. Watch footing and stay clear of ropes, cables, and other obstacles. Use de-icing material to clear ice from walkways. Maintain three points of contact where practicable.
  • Wear properly fitted personal flotation devices (PFD) that are designed to keep an unconscious miner’s face above water.
  • Utilize wearable electronic emergency warning systems to immediately notify others of a fall into water. These devices can be equipped with water activated strobe lights and global positioning system (GPS) tracking.

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.

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.

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.
