renewcomerLeave a comment

2010 MNM Fatality 22On December 17, 2010, a 35 year- old truck driver with 11 weeks of experience died at a crushed stone operation. The victim was standing on a belt conveyor, working inside a chute, when the belt conveyor started. He was pulled out of the chute and conveyed under two other chutes located on the same belt conveyor. After the belt conveyor was shut down, the victim was found under a third chute.

Best Practices

  • Establish safe work procedures before conducting specific tasks on belt conveyors and ensure that the safe work procedures are followed.
  • Train persons to recognize the hazards of working near belt conveyors.
  • Deenergize and block belt conveyors against motion before working near a chute, drive, head, tail, and take-up pulleys.
  • Lock-out/tag-out all energy sources to belt conveyors before working on them.
  • Sound audible warnings or alarms prior to starting belt conveyors.
  • Maintain communications with all persons performing the task. Before re-starting belt conveyors, ensure that all persons are clear.

On Saturday, December 4, 2010, a 32 year old contract truck driver with four years of experience was killed in a Powered Haulage accident on a coal mine haul road. The loaded truck struck the left berm on the elevated roadway and over-turned on the road, trapping the victim under the cab.

Best Practices

  • Never operate a truck or other mobile equipment without using a seat belt.
  • Know the truck’s capabilities, operating ranges, load-limits and properly maintain the brakes and other safety features.
  • Construct roadway berms to appropriate strengths and geometries to prevent driving through them or driving up onto them.
  • Train all employees on proper work procedures, hazard recognition and avoidance, and proper use of roadway berms.
  • Observe all speed limits, traffic rules, and ensure that grades on haulage roads are appropriate for haulage equipment being used.
  • Always select the proper gear and downshift well in advance of descending the grade.
  • Monitor work habits routinely and examine work areas to ensure that safe work procedures are followed
  • Maintain control of equipment at all times, making allowances for the prevailing conditions (low visibility, inclement weather, etc).
  • Maintain equipment braking and steering systems in good repair and adjustment.
  • Do not attempt to exit or jump from a moving vehicle

Highwall Safety Alert

renewcomerLeave a comment

Winter months can bring drastic changes to the stability of highwalls due to freezing and thawing. Water accumulates in crevices of rocks and then freezes. The ice acts as a wedge to expand the crevice opening. The ice thaws and the cycle begins again which in turn compromises the stability of the highwall that can result in highwall failure.

MSHA has issued a Safety Alert that can easily be printed out and posted or used in a toolbox talk.

On Tuesday, November 23, 2010, a 32-year old service man with 6 years of experience, was killed at a surface mine. The victim was driving a tandem axle lube truck down a grade into an active work area of the mine when he lost control of the truck. The truck struck an embankment and overturned onto its left side. The victim either jumped or was thrown from the truck.

Best Practices

  • Conduct pre-operational safety checks of all mobile equipment.
  • Equipment defects affecting safety shall be corrected before the equipment is used.
  • Always wear a seat belt when operating a truck or mobile equipment.
  • Maintain adequate berms on the outer banks of elevated roadways.
  • Construct haulage roads to grade and lane widths appropriate for all equipment used.
  • Train all employees on proper operation procedures, hazard recognition, and avoidance.
  • Ensure traffic rules, signals, and warning signs are posted and obeyed.
  • Maintain equipment braking and steering systems in good repair and adjustment.
  • Do not exceed the truck’s capabilities, operating ranges, load-limits and safety features.
  • Operate vehicles in the appropriate gear and avoid changing gears when descending grades.
  • Ensure there is sufficient illumination of working areas and lights are maintained on mobile equipment.
  • Do not exit or jump from a moving vehicle.

On November 13, 2010, a 42 year- old contract mechanic with 23 years of experience died at a sand and gravel operation. The victim was underneath a front-end loader, with the engine running, checking a hydraulic fluid leak when the machine moved and rolled over him. The machine was parked on a slight grade, the bucket was raised off the ground, and no wheel chocks were in place.

Best Practices

  • Train persons to recognize work place hazards.
  • Establish safe work procedures before a task is performed and ensure that the safe work procedures are followed.
  • Set the park brake and securely block equipment and components against hazardous motion at all times while performing repair or maintenance work.
  • Do not rely on hydraulic systems to hold mobile equipment stationary during repairs or maintenance.
  • Lower the bucket to the ground when parking mobile equipment.

mnm fatality number 19 for 2010On October 20, 2010, a 63 year- old contract truck driver with 41 years of experience died at a fuller’s earth (clay) operation. The victim backed his trailer into a bay at the mine loading dock. He got out of his truck and walked to an adjacent bay to discuss the loading procedures with the fork lift operator. At that time, a second trailer was being moved into the bay and it struck the victim, pinning him against the loading dock.

  • Establish a control policy that includes signs directing all truck drivers to report to a designated office clear of the dock and truck travel areas when dropping or picking up loads.
  • Train all persons to recognize work place hazards and to stay clear of normal paths of travel of mobile equipment.
  • Provide a clearly marked, safe area for pedestrian access to the facility. Clearly mark areas that are unsafe for pedestrian access and prevent entry into those areas.
  • Ensure that illumination is sufficient at the work site.
  • Before moving mobile equipment, look in the direction of travel, use all mirrors, cameras, backup alarms, and installed proximity detection devices to ensure no one is in the intended path.
  • Sound the horn to warn persons of movement and wait to give them time to get to a safe location.
  • Communicate with mobile equipment operators and ensure they acknowledge your presence.
  • Wear high visibility clothing when working around mobile equipment.

MNM Fatality 16 2010

On October 10, 2010, a 42 year- old contract electrician with 4 years of experience was seriously injured at a granite operation. The victim and two co-workers were installing ground fault indicator lights in a circuit breaker enclosure when an arc flash occurred. The circuit breaker enclosure contained a bottom feed circuit breaker. All three workers were hospitalized and the victim died on October 12, 2010.

Before YOU perform electrical work:

  • 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.
  • Install warning labels on the terminal covers of bottom feed circuit breakers stating the “Bottom terminal lugs remain energized when the circuit breaker is open.”
