renewcomerLeave a comment

On May 23, 2012, a 36 year-old foreman with about 9½ years of experience was killed at a sand and gravel operation. He was operating an excavator on a dike separating two ponds. The ground beneath the excavator tracks failed and the excavator toppled into one of the ponds.

Best Practices

  • Examine work areas to identify all hazards and remediate before starting any work.
  • Evaluate the stability of the ground (slopes and berms) prior to operating equipment near any drop off or edge.
  • Always be attentive to changes in ground conditions and visibility when operating machinery.
  • Perform the work at a safe distance away from the edge of a pond or where the stability of the ground may be unknown.
  • If a potential hazard is present, use long reach equipment to limit exposure and maintain a safe distance away.
  • Consider areas that have experienced previous slope failures to be unstable and do not approach until the area is evaluated for stability.
  • Wear flotation devices where there is a danger of falling into water.
  • Be alert to changes in ground conditions such as cracking, bulging, sloughing, undercutting, and erosion.

On September 13, 2011, a 38 year-old miner with 3 years of experience was killed at a portable sand and gravel operation. The victim opened the 480 volt feeder box at the motor control center and started to remove the leads when he received a fatal shock.

Best Practices

  • 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.

On August 9, 2011, a 24-year-old skid-steer loader operator with 12 weeks of experience was killed at a sand and gravel operation. He accessed an elevated platform near an unguarded head pulley and became entangled in the operating conveyor system.

Best Practices

  •  Identify hazards around conveyor systems, design guards, and securely install the guarding.
  • Always provide and maintain guarding sufficient to prevent contact with moving machine parts.
  • Train persons to recognize the hazards associated with performing tasks.
  • Follow established lock-out and tag-out procedures before working on operating systems or moving machine parts.
  • Remain aware of potential hazards in your work area and take actions to eliminate the risks.
  • Do not wear loose fitting clothing when working near moving machine parts.
