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.

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.

  • Ensure that mobile equipment operators are task trained adequately in all phases of mobile equipment operation, including the mobile equipment’s capabilities, operating ranges, load-limits and safety features, before operating mobile equipment.
  • Maintain equipment steering and braking systems in good repair and adjustment. Always follow the manufacturer’s service and maintenance schedules.
  • Never rely on engine brakes and transmission retarders as substitutes for keeping brakes properly maintained.
  • Conduct adequate pre-operational checks to ensure the service brakes will stop and hold the mobile equipment prior to operating.
  • Operators of self-propelled mobile equipment shall maintain control of the equipment while it is in motion.
  • Operating speeds shall be consistent with conditions of roadways, tracks, grades, clearance, visibility, curves, and traffic.
  • Do not attempt to exit or jump from moving mobile equipment.

Best Practices

  • Establish policies and procedures for conducting specific tasks.
  • Before beginning any work, ensure that persons are properly task trained and understand the hazards associated with the work to be performed.
  • Maintain communications with all persons performing the task.
  • Conduct adequate pre-operational checks and ensure that all braking systems on mobile equipment are functioning properly.
  • Do not work or cross between rail cars unless the locomotive is stopped and the operator is notified and acknowledges your presence.
  • Never place yourself between rail cars without blocking them to prevent movement.
  • Maintain the track and track mounted equipment to prevent derails.

  • Establish and discuss safe work procedures. Identify and control all hazards associated with the work to be performed along with the methods to properly protect persons.
  • 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.
