Section: 56.14107a
Date: 04/21/2011
District: NC
Negligence: Moderate
Injury or Illness: Unlikely
Injury or illness could be expected to be: Lost Workdays or Restricted Only
Significant and Substantial: No

Condition or Practice: Guarding was not provided for the Snubbers on each side of the screen. Two Snubbers on each side vibrate during Scalper Screen operation creating a pinch point between the snub and bracket. The Snubbers are positioned low on the screen side and there isn't any maintenance activities performed near the unguarded parts making an accident unlikely. Should a miner contact the moving machine part it would result in lacerations, contusions and/or fractured bone injuries.

Action to Terminate: The snubber brackets were removed.

Why this concerns you: Possibly every scalper screen has snubbers like these as original equipment designed by the manufacturer. Look at the picture then check your screens.



Abatement Suggestions From Industry


This does not appear to be a legitimate citation as it is not truly a moving part or pinchpoint and MSHA has not historically required guarding of these, which makes a fair notice/due process defense available. It is interesting that a guard was not required to abate this. I would want to know what the manufacturer thinks about removing the brackets. Does this modify the design in a way that creates a hazard?

More than likely removing the snubbers would void the manufacturers warranty.

You may well have an argument that those items are not "similar moving parts", as all the items mentioned in the standard itself are rotating drums/shafts/cylinders.

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.
