Mining Fatalities

Fatality #14 for Metal/Nonmetal Mining 2011

renewcomerLeave a comment

On November 17, 2011, a 26 year-old contract underground miner with 3½ years of experience was seriously injured in a silver mine. He died at a hospital on November 19, 2011. The victim and a coworker were attempting to dislodge muck in a bin excavation when the muck they were standing on started to flow. The victim was wearing a safety harness attached to a self-retracting lanyard; however, the lanyard extended and did not lock before he became engulfed. The other miner was freed immediately, treated, and released from the hospital.

Best Practices
 

  • Wear a safety harness and attach it to a securely anchored lanyard, where there is a danger of falling.
  • In applications where the danger is not limited to a free-fall, do not use lanyards that depend on free-fall speed to lock. Follow the manufacturer’s recommendations.
  • Ensure that persons working on material in bins, silos, hoppers, tanks, and surge piles are properly tied-off, with one line tender per person. No persons should enter the facility until the supply and discharge equipment are locked out.
  • Establish policies and procedures for safely clearing muck in a bin excavation and ensure that persons follow these safe procedures.
  • Ensure that persons are task-trained and understand the hazards associated with the work being performed and the proper use of their personal protective equipment.

On November 7, 2011, an 82 year-old owner/crusher operator with 27 years of experience was killed at a surface crushed stone operation. The victim was attempting to dislodge material from the vibrating feed hopper when he slipped or fell into the operating jaw crusher.

Best Practices

  • Establish policies and procedures for safely clearing plugged material in a feed hopper. Evaluate design modifications or use auxiliary equipment to reduce the risks associated with clearing an obstruction.
  • Ensure that persons are task trained and understand the hazards associated with the work being performed.
  • Deenergize and Lock-out/tag-out all power sources before working on crushers.
  • Provide and maintain a safe means of access to all working places.

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.

Fatality #12 for Metal/Nonmetal Mining 2011

renewcomerLeave a comment

On October 31, 2011, a 42 year-old muck haul leadman with 3½ years of experience was killed in an underground platinum mine. The victim was operating a 4-yard loader in a drift when the loader struck the left rib. At that time, a spieling (rebar anchored in the rib for ground control) that was protruding from the rib, penetrated the front side window, entered the cab, and struck him.

Best Practices

  •  Operators of self-propelled mobile equipment shall maintain control of the equipment while it is in motion.
  • Maintain all roadways free of materials that may pose a hazard to equipment operators. This includes materials on the floor and protruding from the ribs, back, or walls.
  • Operating speeds shall be consistent with conditions of roadways, tracks, grades, clearance, visibility, curves, and traffic.
  • Slow down or drop to a lower gear when necessary. Post areas where lower speeds are warranted.
  • Always wear a seat belt when operating self-propelled mobile equipment.
  • Trim protruding spielings.
  • Keep mobile equipment operator’s stations free of materials that can impair the safe operation of the equipment.
  • When clearances on roadways are restricted, install warning devices in advance of the area and conspicuously mark it.

On October 28, 2011, a 21 year-old contract tire repair technician with 37 weeks of experience was killed at a surface gold operation. The victim was working in a shop repairing a haul truck tire. He was applying adhesive inside the tire and was completely out of view. He was not wearing respiratory protection.

Best Practices
 

  • Develop, implement, and maintain a written Hazard Communication (HazCom) program.
  • Ensure that a Material Safety Data Sheet (MSDS) is accessible to persons for each hazardous chemical to which they may be exposed.
  • 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.

Four Miners Killed in Four Days

renewcomerLeave a comment

The mining industry recently experienced four mining deaths within four days. In an effort to remind operators, miners, and contractors to stay focused on preventing fatalities and injuries, the Mine Safety and Health Administration is distributing best practice and preventative measure information in the form of a Safety Alert and a 2011 3rd quarter fatality update.

The Safety Alert is a poster that can be displayed in the mine to remind operators, miners, and contractors of the fatalities that occurred between Oct 28 -31, 2011. It lists actions to take to prevent these kinds of accidents.

The 3rd quarter fatality update analyzes the mining fatalities for the third quarter of 2011 and best practices to prevent them.

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.
