Section: 56.14107a
Date: 02/21/2011
Negligence: High
Injury or Illness: Reasonbly Likely
Injury or illness could be expected to be: Permanantly Disabling
Significant and Substantial: Yes

Condition or Practice: A return roller was found not guarded. This was on the Scalper Screen under conveyor. The roller was near 63 inches wide and 74 inches above the ground. This was a large area under the #90-037 Simplicity screen that one could easily walk underneath. Usually one miner would clean up around this area daily on a shift. Clean up duties are performed by a skid steer loader that has other clean up attachments to more effectiviely clean under the equipment. This condition creates a potential entanglement hazard to the miner.

Note: This plant was last operated during Sepember, 2010.

Action to Terminate: An adequate return roller guard was installed in the effected area.

Why this concerns you: Inspector knew the plant was shut down, MSHA notice sent to District Office. No one in area of inactive plant, maintenance not completed on plant-clearance was a build up issue not height issue. Mechanical cleaning equipment not exposed personnel

Abatement Suggestions From Industry

See the following from the MSHA Program Policy Manual...Another example of MSHA wavering on their standards...This situation is not identical, but return idlers have typicall not been cited

56/57.14107 Moving Machine Parts
All moving parts identified under this standard are to be guarded with adequately constructed, installed and maintained guards to provide the required protection. The use of chains to rail off walkways and travelways near moving machine parts, with or without the posting of warning signs in lieu of guards, is not in compliance with this standard.

Conveyor belt rollers are not to be construed as "similar exposed moving machine parts" under the standard and cannot be cited for the absence of guards and violation of this standard where skirt boards exist along the belt. However, inspectors should recognize the accident potential, bring the hazard to the attention of the mine operators, and recommend appropriate safeguards to prevent injuries.

This standard is to be cited when a guard at conveyor locations does not extend a distance sufficient to prevent any parts of a person from accidentally getting behind the guard and becoming caught, or in those instances when there is no guard at the conveyor-drive, conveyor-head, conveyor-tail, or conveyor take-up pulleys.

Be nice!
If you are angry, step back and take a breath.

Post like you are talking to someone face-to-face. Better yet, post it like your mother is going to read it.

Don't discuss anything that might be construed as restraining trade. Nothing about boycotts and we certainly don't want to read about the price of rock.

Be honest!
Keep it factual. There is absolutely no need to exaggerate; some citations are hard enough to believe as is. Mine safety is important and those who visit the site must be able to rely on posts being accurate.

We review all posts
Sorry, but all posts come to us first. We want this site to be effective, and we want you to use it. The site can only be effective if it is legal and professional. If we get something that isn't both, we won't post it. None of us want that to happen.

No Guarantees
Anyone who has been a mine safety professional for long knows what one inspector approves, another may consider a violation. As much as we would like to, we cannot guarantee any solution offered here will work for your situation. We certainly hope what others have done provides helpful ideas, but we aren't willing to bet the farm on it passing an inspection and you shouldn't either.
