METAL/NONMETAL MINE FATALITY - - On December 21,
1999, a 22-year-old Laborer with 2 weeks of
mining experience was fatally injured when his
clothes became entangled in a self cleaning
pulley and he was subsequently pulled into the
moving machine parts. The victim had entered into
a confined space area containing an unguarded
self-cleaning pulley that was in operation.
Guards had been provided to protect persons from
the moving machine parts, however, the guards had
been removed and were laying on the ground.
Best Practices gtEach work place must be
examined at least once on each shift for
conditions which may adversely affect safety or
health gtPrompt action must be initiated to
correct hazardous conditions gtMoving machine
parts must be guarded to protect persons from
contacting them gtGuards must be securely in
place while machinery is being operated gtNew
employees must be indoctrinated in safety rules
and safe work procedures

belt when he was caught and drawn into the pinch
point at a return roller.  
                                                
                                                

• Maintenance should not be performed unless the
  power is off and machinery components are blocked
  against hazardous motion.
• Moving machine parts should be guarded to protect
  persons from contact that could cause injury.

METAL/NONMETAL MINE FATALITY - On April 12,
2000, a 38-year-old laborer with 4 years mining
experience was fatally injured at a crushed stone
operation. The victim and a co-worker were making
adjustments to a new conveyor installation. The
victim was aligning the extended grease lines for
the bend pulley from inside the conveyor frame.
He was caught and drawn into the pinch point when
the conveyor was started without his knowledge.
                                                
                                                  
                                                 

• Best Practices
• Maintenance should not be performed unless the
  power is off and machinery components are blocked
  against motion.
• Visible or audible warinings should be provided
  before conveyor start-up when the entire length
  of the conveyor is not visible from the starting
  switch.
• Mine operators should take measures to assure all
  personnel are trained in safe work procedures.

METAL/NONMETAL MINE FATALITY - On April 21,
2000, an 18-year-old plant operator with 1 year
mining experience was fatally injured at a sand
and gravel operation. The victim, who had been
operating the plant alone, became entangled in
the unguarded tail pulley of the sand washer
conveyor.

• Best Practices
• Moving machine parts should be guarded to protect
  persons from contact that could cause injury.
• Conveyors should be provided with emergency stop
  cords along their entire length.
• Mine operators should take measures to assure all
  personnel are trained in safe work procedures.

Equipment Guarding

• MSHAs number one citation for the past several
  years.
• Shafts, sprockets, pulleys, rotating parts and
  pinch points must be guarded.
• Guards cannot create a hazard.
