Fatality #2 for Coal Mining 2011

renewcomerLeave a comment

On February 3, 2011, a 49 year old dozer operator, with 2 years mining experience, was killed at a surface area of an underground coal mine. The accident occurred at an access road leading to a gas well plugging site. The victim parked on a grade and dismounted the dozer to assist a truck driver connect a winch cable from the dozer to the water truck. The dozer drifted backward into the water truck, pinning the victim between the truck and the dozer. The parking brake was not set and the blade was not lowered on the dozer.

On March 25, 2011, MSHA Solicitors made a determination that this fatality is not under MSHA jurisdiction, and therefore, not chargeable to the mining industry.

Best Practices

  • Ensure that equipment operators are trained and knowledgeable about equipment operation and the associated hazards.
  • Perform pre-operational equipment checks for defects and repair any defects found before operating equipment.
  • Analyze the job for what needs done and look for what could go wrong. More information can be obtained here: http://www.msha.gov/SLAMRisks/SLAMRISKS.pdf
  • Block dozers against motion by lowering the blade, setting parking brakes, and shutting off the machine.
  • Position equipment on flattest grade possible to connect equipment for towing, and consider positioning the tow machine at a distance and angle that would prevent a rollback collision.
  • Stay in equipment, if equipment has the potential to move.

CAT Forklift Safety Brochure

renewcomerLeave a comment

CAT has some really nice safety materials free for the asking or as it goes on the internet, free for the taking. The one this illustration comes from nicely covers the general hazards of operating just about any kind of forklift.

It includes Safety Information for Operators, a sample Pre-operation checklist, and Information for Employers which applies specifically to OSHA regulations, but certainly addresses best practices concerning task training on MSHA sites with such equipment.

Download the PDF, print it out, and use it for a toolbox talk for operators or anyone who works were forklifts are used.

To supplement it you may want to use the fatalgram and investigation for a Coal fatality that involved such a piece of equipment. It happened on the surface of an underground mine, but the hazards apply to just about any mining or construction site.

crane and derrick banner osha

OSHA announced on 7/28/10 that it is issuing a new rule addressing the use of cranes and derricks in construction, which will replace a decades-old standard. Approximately 267,000 construction, crane rental and crane certification establishments employing about 4.8 million workers will be affected by the new rule.

The previous rule, which dated back to 1971, was based on 40-year-old standards. Stakeholders from the construction industry recognized the need to update the safety requirements, methods and practices for cranes and derricks, and to incorporate technological advances in order to provide improved protection for those who work on and around cranes and derricks.

Caterpillar Seat Belt Replacement

renewcomerLeave a comment

Seat BeltBecause the Caterpillar operator manuals and other literature say that you must replace seat belts after three years, you may have to replace perfectly good seat belts. MSHA can enforce such requirements from manufacturers.

We can debate that for a long time, but let’s start back a step. Are you replacing seat belts when they become damaged or worn? While CAT’s policy may have created this firestorm (which is before the courts somewhere I’m told) it should at least lead us to take a good look and start by replacing seat belts that should be replaced. For that CAT has a very nice little tool. It’s a toolbox talk that provides a checklist that reminds us that it’s more than the webbing that should be examined. You can download the pdf file below. Why not give a copy to each of your operators (CAT equipment or not) and be sure that these lifesaving devices will function when called upon. I’ve also included an online checklist from an Australian aftermarket supplier.

If you are going to replace that seat belt and want to do it with something other than one from the manufacturer, be sure to meet the requirements of 30 CFR 56/57.14130(h) and 56/57.14131(c). They should have a tag on them showing adherence to the latest versions of SAE J386 or SAE J1194 standards. Check out the MSHA links below.

Fatality #33 for Coal Mining 2010

renewcomerLeave a comment

On Thursday, April 22, 2010, a 28-year old continuous mining machine operator with 5 years of experience was fatally injured when he was crushed between the conveyor boom of the continuous mining machine and the coal rib. The victim was located near the continuous mining machine while positioning it. The mining height in this area was approximately five feet.

Best Practices

  • Ensure the continuous mining machine operator is positioned beyond the turning radius, and away from the conveyor boom turning radius before starting or moving the equipment.
  • Frequently review, retrain, and discuss avoiding the “RED ZONE” areas when operating or working near a remote controlled continuous mining machine.
  • Pursue new technology, such as proximity detection, to protect personnel from accidents of this type. See the proximity detection single source page on the MSHA web site.
  • Minimize the number of miners working or traveling near continuous mining machines and maintain effective communications between miners and equipment operators.
  • Train all productions crews and management in programs, policies, and procedures for operating remote controlled continuous mining machines.

Fatality #32 for Coal Mining 2010

renewcomerLeave a comment

On April 11, 2010, a 61-year old contract iron worker/mine fireboss with 20 years of mining experience was fatally injured while installing pre-fabricated metal stairs on the side of a fan housing. The stair stringer had been hoisted into place and clamped at the top with two “locking pliers-type” C-clamps. The bottom of the inclined stringer was lying on a 6×6 inch timber. To level the stair treads, a 6×6 inch timber was going to be replaced with a 4×4 inch timber. To replace the 6×6 timber, rigging was fastened near the lower part of the stringer. The victim was standing on the ground holding the handrails. As the lower end of the stringer was hoisted by the crane, the clamps opened and the top end of the stringer fell. This caused the bottom end of the stringer to pivot up and swing out. This pushed the victim backward and pinned him against a nearby manlift.

Best Practices

  • Ensure that all personnel stay clear of hoisted loads and areas where loads may fall if hoisting fails.
  • Know the limitations of temporary supports and ensure they are used within their specifications.
  • Ensure all components are adequately blocked and secured to prevent unintended motion.
  • Use taglines on loads to be hoisted that will need steadying or guidance.
  • Ensure that crane operators communicate with other workers in close proximity to loads that are going to be moved.
  • Ensure that personnel are trained to recognize hazardous work procedures.
  • Discuss work procedures and identify all hazards associated with the work to be performed, along with the methods to protect personnel.
