MSHA Safety Alert Posted – Accidents Occur When You Least Expect IT

renewcomerLeave a comment

mshafatalsThree fatal accidents have occurred within a week at metal and nonmetal mines. These accidents might have been avoided had there been proper berms, proper risk analysis, and careful planning before work began. MSHA has issued an alert. October is statistically one of the worst months for fatalities and unfortunately it looks like we got a head start. These three have not had fatalgrams posted yet. They will be posted here as soon as they are released by MSHA.

Meanwhile, the alert can be found here.

Fatality #14 for Coal Mining 2013

renewcomerLeave a comment

ftl2013c14On July 3, 2013, an 87-year-old contract employee was mowing an impoundment embankment with a skid steer machine equipped with a front-mounted brush mower. The victim was mowing the 40 degree embankment in a vertical direction when the machine traveled into the impounded water, submerging the machine, and drowning the operator.

Best Practices

  • Conduct a risk assessment prior to performing work and ensure that miners use proper equipment, tools, and procedures to eliminate hazards.
  • Provide hazard training to all personnel working on or near an impoundment for recognition of hazards associated with the impoundment.
  • Set up a communications protocol when persons are working alone.
  • Wear properly fitted personal floatation devices (PFD) when working around bodies of water.
  • Never assume an employee is knowledgeable in the task they are being assigned.

ftl2013c13On Friday, August 16, 2013, a 24-year-old utility person with nearly 3 years of mining experience was killed when the Ford F350 utility pickup truck he was driving was crushed by a P&H 2800 electric shovel. A bulldozer and two pickup trucks were following the shovel while traveling up a grade (approximately 9%). The shovel rolled backward down the grade and hit the bulldozer and the two trucks. The driver of the first truck was killed, and the driver of the second truck sustained injuries and was transported to the hospital.

Best Practices

  • Ensure the grade is within equipment capabilities and equipment braking and steering systems function as designed.
  • Establish procedures that require smaller vehicles to maintain a safe distance from large mobile equipment. Provide training in those procedures.
  • Use clear communication at all times. Utilize radios to communicate when visual contact cannot be maintained.
  • Ensure road widths are sufficient for equipment movement.
  • Designate specific roadways or provide alternate routes for light duty vehicles in high activity or congested areas.
  • Ensure sufficient clearance is available for equipment movement.

ftl2013c12On Tuesday, August 6, 2013, a 56-year old continuous mining machine operator, with 37 years of mining experience, was killed as a result of a coal rib outburst. The section crew was retreat mining the first right lift of the #3 entry in a five entry system when the accident occurred. Two other miners were injured, one seriously.

Best Practices

  • Ensure that the approved roof control plan support provisions are suitable for the geological conditions at the mine and that the plan is followed.
  • Ensure that the pillar dimensions and mining method are suitable for the conditions. OR, ensure that roof and rib control methods are adequate for the depth of cover and for the potential effects of any mines above or below active workings.
  • Develop a map of geological features and anomalies to determine orientation as a means to predict when and where they will be encountered during mining, so additional roof support can focus on those areas.
  • Conduct frequent and adequate examinations of roof, face, and ribs. Be alert for changing conditions. When hazardous conditions are detected, danger off access to the area until it is made safe for work and travel.
  • Maintain proper entry widths and pillar dimensions.
  • When gob falls have been delayed for periods that exceed routine intervals for the mining conditions, evaluate the area and consider evacuating miners and equipment to a safe area until the fall occurs.

ftl2013c11On July 31, 2013, a 28-year-old mechanic with 7 years of experience, was killed while checking a strut on a rock truck. He was removing the top cap of the strut when the cap loosened, allowing the truck frame to abruptly drop. The victim was pinned between the top of the right front tire and the bottom of the fender.

Best Practices

  • Perform maintenance and repairs only after blocking machinery and components against motion.
  • Before loosening hydraulic hoses or components, determine if they are supporting something or trapping pressure.
  • Ensure warning labels are visible. Check them regularly and replace any labels that are illegible.
  • Consult and follow the manufacturer’s recommended safe work procedures for the maintenance task, and monitor work to ensure procedures are followed.
  • Ensure that safe work procedures are in place for specific tasks, machines, etc.
  • Before performing any job, consider all hazards and implement formal procedures that address hazards.
  • Ensure that you are positioned in a safe location when performing maintenance and repairs.

ftl2013m10On August 5, 2013, a 55-year old plant manager with 5 years of experience was killed at a crushed stone operation. The victim looked into an operating crusher and a tooth, that broke free from an excavator bucket, was ejected from the crusher and struck him.

Best Practices

  • Establish and discuss policies and procedures for safely clearing a cone crusher. Consider a mechanical method for clearing material to minimize exposure to persons performing the work.
  • Task train persons to recognize all potential hazardous conditions and to understand safe job procedures for elimination of the hazards before beginning work.
  • Before working on or near equipment, ensure the equipment power is off and locked out/tagged out. Ensure the equipment has been securely blocked against hazardous motion to ensure energy cannot be released while performing work.
  • Always maintain equipment in a safe operating condition.
  • Provide a safe means of access for persons required to maintain a cone crusher.
  • Provide guards, shields, or other devices to protect persons from the hazard of flying or falling materials generated from the operation of screens, crushers, or conveyors.
  • Implement measures to ensure persons are properly positioned and protected from hazards while performing a task.

ftl2013c10On Tuesday, July 2, 2013, a 35-year old continuous mining machine operator (victim), with 11 years mining experience, was killed when he was struck by a battery-powered coal hauler and pinned between the coal hauler and the coal rib. The victim was taking a lunch break behind a line curtain the No. 4 entry and the intersection of the last open crosscut, which was in the haulage route to the continuous mining machine.

Best Practices

  • Ensure that all persons are positioned to avoid danger from moving equipment. Never position yourself in an area or location where equipment operators cannot readily see you.
  • Use proximity detection systems to protect personnel from accidents of this type. See the proximity detection single source page on the MSHA web site.
  • Use transparent curtain for check and line curtains in the active face areas.
  • Sound audible warnings when the equipment operator’s visibility is obstructed, such as when making turns, reversing direction, or approaching ventilation curtains. Assure that the sound level of audible warnings is significantly higher than that of the ambient noise.
  • Energize the lights in the direction of travel when operating haulage equipment.
  • Equipment operators should come to a complete stop and sound an audible warning before proceeding through ventilation controls.

It’s the Law… Depending Where You Are

seatbeltWhat ARE the seatbelt laws across the country. My own state of Pennsylvania is in the minority with no Primary seat belt enforcement, meaning you have to be stopped for another infraction to receive a fine for not wearing a seat belt. I happen to like Wyoming which, although it has no primary enforcement either, you get a $10 reduction on your other fine if you had your seat belt on! Wow, positive reinforcement on the highway!

If you’re traveling across the company you can use the information on the Insurance Institute for Highway Safety’s web page to stay within the law. Better yet, ALWAYS BUCKLE UP!
