Fatality #10 for Metal/Nonmetal Mining 2011

renewcomerLeave a comment

On September 23, 2011, a 32 year-old plant operator with 10 years of experience was killed at a sand and gravel operation. The victim was changing a screen in the plant when he fell approximately 56 feet to the ground below. He was standing on a steel rail that had been placed between the midrail of the protective rail surrounding the screen deck work platform and the screen structure.

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 purpose of fall protection barriers and the proper use of fall protection.
  • Always use fall protection when working where a fall hazard exists.

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.

The Deadliest Month?

renewcomerLeave a comment

MSHA has issued an alert for October based on numbers that show that for Metal/Nonmetal mines it is the deadliest month.

Of course it’s a good idea to pay extra attention to safety any month, any week, or any day, but this certainly indicates there are factors in the industry that could make October a special month to pay attention to safety. Download the printout below from MSHA to post or distribute to your miners.

Fatality #8 for Metal/Nonmetal Mining 2011

renewcomerLeave a comment

On September 7, 2011, a 30 year-old miner with I year of experience was killed at an underground gold mine. The victim was on a ramp waiting for a blast to be initiated. When the round was initiated, small rock and debris traveled through a 3-inch diameter diamond borehole, striking him.

Best Practices 

  • Plug a diamond drill hole that intersects any opening and map the hole.
  • During blasting operations, consider mine specific conditions, including diamond drill holes and rock strata, and establish mine policies and procedures to protect all persons.
  • When developing a blasting plan, make sure all drilled holes and open passageways that intersect the area to be blasted are known and taken into consideration before initiating any blast.
  • Use a central blasting system and schedule blasting between shifts or on off-shifts when no one is present.
  • Train persons to identify hazards associated with blasting activity and take action to correct them.
  • Never initiate a blast until the blast area has been determined to be safe and all persons have been evacuated from the designated blasting area.
  • Take special precautions to ensure that all roadways and regularly traveled areas are blocked to prevent access when blasting is being conducted.

Fatality #15 for Coal Mining 2011

renewcomerLeave a comment

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 #14 for Coal Mining 2011

renewcomerLeave a comment

On Monday, August 15, 2011, a 46 year old miner was killed when he was struck by a portion of the mine roof that fell from an area adjacent to a longwall shield. The accident occurred during a longwall move, while the victim was installing a wooden crib in an area where a longwall face shield had been removed previously. The victim had approximately five years experience with this activity.

Best Practices
  • Assure that roof control plans are suitable to the prevailing geological conditions. If roof geology changes affect roof stability, reevaluate roof support techniques.
  • Share and discuss roof control plans with the miners on a regular basis. For miner safety, assure that the roof control plan safety precautions are followed.
  • Provide additional training for specialized work, such as longwall moves, emphasizing best practices for a specific task.
  • Conduct examinations of roof conditions frequently to prevent exposure to poor roof conditions. Remain vigilant for changing roof conditions.
  • When hazardous roof conditions are detected, danger off areas until they are made safe.

On August 9, 2011, a 24-year-old skid-steer loader operator with 12 weeks of experience was killed at a sand and gravel operation. He accessed an elevated platform near an unguarded head pulley and became entangled in the operating conveyor system.

Best Practices

  •  Identify hazards around conveyor systems, design guards, and securely install the guarding.
  • Always provide and maintain guarding sufficient to prevent contact with moving machine parts.
  • Train persons to recognize the hazards associated with performing tasks.
  • Follow established lock-out and tag-out procedures before working on operating systems or moving machine parts.
  • Remain aware of potential hazards in your work area and take actions to eliminate the risks.
  • Do not wear loose fitting clothing when working near moving machine parts.

Fatality #13 for Coal Mining 2011

renewcomerLeave a comment

On Monday, August 8, 2011, a 41-year-old longwall mechanic with nine years of mining experience was killed when he was struck in the chest by a piece of metal from the top of a base lift jack mounted on a longwall shield. The jack catastrophically failed resulting in the end cap separating from the cylinder and striking the victim.

Best Practices

  • Do not alter hydraulic circuits in a manner that could result in the trapping of pressurized hydraulic fluid.
  • When isolating hydraulic components for repair, ensure that the hydraulic system has a means to bleed the pressure from the components being repaired.
  • Evaluate potential energy sources before working in tight spaces. Click on the following link for more information: MSHA – SLAM Risks the Smart Way – Safety and Health Outreach Program Home Page
  • Ensure re-built components meet original equipment manufacturer (OEM) specifications.
  • Ensure miners are adequately trained in proper maintenance procedures and plan requirements.
  • Examine and periodically inspect all hydraulic components for defects.
  • Ensure the ratings of hydraulic components are compatible with their intended use.
