  • 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.

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.

On September 7, 2011, a 30 year-old miner with I year of experience was killed at an underground gold mine. The victim was on a ramp waiting for a blast to be initiated. When the round was initiated, small rock and debris traveled through a 3-inch diameter diamond borehole, striking him.

Best Practices 

  • Plug a diamond drill hole that intersects any opening and map the hole.
  • During blasting operations, consider mine specific conditions, including diamond drill holes and rock strata, and establish mine policies and procedures to protect all persons.
  • When developing a blasting plan, make sure all drilled holes and open passageways that intersect the area to be blasted are known and taken into consideration before initiating any blast.
  • Use a central blasting system and schedule blasting between shifts or on off-shifts when no one is present.
  • Train persons to identify hazards associated with blasting activity and take action to correct them.
  • Never initiate a blast until the blast area has been determined to be safe and all persons have been evacuated from the designated blasting area.
  • Take special precautions to ensure that all roadways and regularly traveled areas are blocked to prevent access when blasting is being conducted.

On June 4, 2011, a 39 year-old mill operator with 1 year and 14 weeks of experience was killed at a surface gold operation. The victim was sweeping in a crusher building when he fell through an opening approximately 60 feet to the floor below. The cover for the opening was not secured in place.

Best Practices

  • Establish and discuss safe work procedures. Identify and control all hazards. Train all persons to recognize and understand safe job procedures before beginning work.
  • Always use fall protection when working where a fall hazard exists.
  • Protect openings near travelways through which persons may fall by installing railings, barriers, or covers.
  • Keep temporary access opening covers secured in place at all times when the opening is not being used.
  • Ensure that areas are barricaded or have warning signs posted at all approaches if hazards exist that are not immediately obvious.

On April 25, 2011, a 31 year- old drill operator with 6 weeks of experience was killed at an underground crushed stone operation. He was walking in a crosscut when a slab of roof, approximately 5 feet wide by 6 feet long by 10 inches thick, struck him.

Best Practices

  • Train persons to identify work place hazards and take action to correct them.
  • Design, install, and maintain a support system to control the ground in places where persons work or travel.
  • Examine and test ground conditions in areas where work is to be performed prior to work commencing and as ground conditions warrant during the shift.
  • When ground conditions create a hazard to persons, install additional ground support before other work is permitted in the affected area.
  • Be alert to any change of ground conditions.
