ftl2013m06On April 27, 2013, a 58-year old mechanic with 2 years of experience was killed at a surface gypsum operation. The victim was clearing a blockage on a mobile track-mounted crusher when he became entangled in the discharge conveyor.

Best Practices

  • Establish policies and procedures for conducting specific tasks on belt conveyors.
  • Before beginning any work, ensure that persons are task trained and understand the hazards associated with the work to be performed.
  • Do not perform work on a belt conveyor until the power is off, locked, and tagged, and machinery components are blocked against motion.
  • Provide emergency stop mechanisms at the control panel(s) and at ground level where maintenance or repair work is performed.
  • Provide appropriate controls to protect any person working near a stalled conveyor from unexpected motion.
  • Maintain communications with all persons performing the task. Before starting belt conveyors, ensure that all persons are clear.

  • Task train all persons to recognize all potential hazardous conditions, to ensure all persons have left the blast area, and to understand safe job procedures for elimination of the hazards before beginning work.
  • Maintain and use all available methods of communication, such as sirens and radios, to warn persons of an impending blast. Establish methods to ensure that all persons are out of the blast area.
  • Before firing a blast give ample warning to allow all persons to be evacuated.
  • Guard or barricade all access routes to the blast area to prevent the passage of persons or vehicles.
  • Verify that the blasting procedures are effective and being followed at all times.

On October 24, 2012, a 52-year old utility miner with 19 years of experience was killed on the surface of an underground limestone mine. He was operating a forklift, traveling on a decline toward the mine entrance, when the forklift went out of control. The forklift struck a concrete support for the belt conveyor and overturned, killing him.

Best Practices

  • Conduct adequate pre-operational checks and ensure the service brakes are properly maintained and will stop and hold the mobile equipment prior to operating.
  • Ensure that mobile equipment operators are adequately task trained in all phases of mobile equipment operation before performing work.
  • Ensure the load is stable and secured on the forks of the forklift.
  • When descending a grade, operate the forklift with the load in the upgrade position.
  • Maintain control of self-propelled mobile equipment while it is in motion.
  • Operating speeds shall be consistent with conditions of roadways, tracks, grades, clearance, visibility, curves, and traffic.
  • Operate equipment within its designed limitations. 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.

Fatality #15 for Metal/Nonmetal Mining 2012

renewcomerLeave a comment

On October 10, 2012, a 55-year old contract painter with 35 years of experience was killed at a kaolin and ball clay operation. He was standing on the bottom of a 40-foot high, 50-foot diameter tank that was open to the atmosphere and covered with mesh cloth material. He was spraying coal tar on the inside walls of the tank and was found unconscious by coworkers. He was recovered by emergency personnel and pronounced dead at a hospital.

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 with employees that may be exposed to hazardous chemicals. 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, gloves, body suits, hearing, and eye & face protection.
  • Ensure that adequate 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.
  • Conduct air monitoring with calibrated instruments to ensure a safe working atmosphere. Air monitoring should be done prior to workers entering the confined work space and continuously till the workers have exited the enclosed area. Atmospheric monitoring at minimum includes Oxygen, LEL and all potential toxic gases in the work place.

Based on MSHA’s investigation and the finding of the death certificate, MSHA later concluded that the miner died from natural causes and that the fatality is not chargeable.

On September 26, 2012, a 79-year old foreman with 56 years of experience was killed when he was run over by the dozer he had been operating. The victim exited the cab and was positioned on the left track checking the engine throttle linkage when the dozer moved forward.

Best Practices
 

  • Inspect equipment before placing it in operation for the shift.
  • Correct safety and operational defects on equipment in a timely manner to prevent the creation of a hazard to persons.
  • Establish safe work procedures and identify and remove hazards before beginning a task.
  • Prior to beginning work, ensure that persons are task-trained and understand the hazards associated with the work being performed. Know and follow safe work procedures before beginning repairs.
  • Block dozer against motion by lowering the blade and ripper to the ground and setting the parking brake. Set the transmission lock lever to ensure the transmission is in neutral.
  • Do not place yourself in a position that will expose you to hazards while performing a task.
  • Monitor personnel routinely to determine that safe work procedures are followed.
