MSHA Guarding Slide Presentation

This slide presentation, compiled in 2010, provides detailed information to help the metal and nonmetal mining industry meet MSHA’s requirements for guarding conveyor belts.  Photos of a variety of situations show the right and wrong ways to construct guards that protect miners from exposure to conveyor belt moving parts and satisfy MSHA regulations. The information supplements guarding guidance in MSHA’s  2004 Guide to Equipment Guarding and Program Policy Manual.

MNM Fatality – 3/5/21

On March 5, 2021, a 63 year old mine manager* was fatally injured when the excavator he was operating rolled over into a body of water at a sand and gravel mine with 5 employees in Mount Sterling, IL*.

Best Practices: 

  • Construct berms or install guardrails on roadways where a drop-off exists.  Ensure berms and guardrails are at least as high as the mid-axle height of the largest equipment using the roadway.
  • Examine and maintain roadways to prevent slope instability such as over steepened banks, sloughs, and cracking on the roadway and bank.
  • Install locked gates at the entrances of roadways that are infrequently traveled.  Post speed limit signs and install delineators at the edges of roads.
  • Always wear seatbelts when operating mobile equipment.
  • When working near water, wear flotation devices and ensure combination seat belt cutter/window breaker tools are installed in equipment.  See safety alert https://www.msha.gov/news-media/alerts-hazards/mnm-safety-alert-water-related-safety.
  • Train equipment operators in the safe performance of their tasks, potential hazards, and the use of alternative/emergency exits in cabs.  Examine these exits during pre-operational examinations.

Additional Information: 

This is the sixth fatality reported in 2021, and the second classified as “Machinery.” (*details added by safeminers.com from MSHA data.)

MNM Fatality – 2/25/21

On Feb. 25, 2021, a 26-year old plant operator died after entering a cyclone discharge box at an industrial sand mine with 9 employees in West Valley City, Nevada*.  The local fire department recovered the victim lodged in an 18-inch wide discharge pipe that was full of water.

Best Practices: 

  • Wear a fall protection harness, properly tie off to a permanent support structure, and attach a lifeline when entering a bin or other confined space.  Have a second person monitor the lifeline to make sure there is no slack in the fall protection system.
  • Use personnel lifts or ladders to safely access elevated work areas.
  • Always use fall protection when there’s a potential fall hazard.
  • Examine work areas and equipment.  Report defects and do not use unsafe work equipment.
  • Assess risks and hazards before beginning maintenance activities.
  • Train miners to safely perform their tasks and properly use their personal protective equipment.

Additional Information: 

This is the fifth fatality reported in 2021, and the first classified as “Slip or Fall of Person.” (*details added by safeminers.com from MSHA data.)

Need a New Pair?

When do you need a new pair of work shoes? Don’t wait until they cost you a painful slip and fall. This CDC/NIOSH graphic is available in English and Spanish. Download it and use it in training or post for employees to read. Of all the tools we should inspect before use your shoes may be the one you actually use the most but don’t even think about it. A new pair of workshoes may seem expensive if you think you can extend them a few weeks with some duct tape, but they don’t come even close to costing as much as a hospital visit even if you aren’t paying the bill.

COVID19 Protection for Miners

MSHA has issued guidance intended for miners and operators in coal, metal, or nonmetal mines to help them identify risks of being exposed to SARS-CoV-2, the virus that causes COVID-19, at work and to help them determine appropriate control measures to reduce such risk. This guidance contains recommendations, as well as descriptions of mandatory safety and health standards. It is not a standard or regulation, and it creates no new legal obligations. The recommendations are advisory in nature, informational in content, and are intended to assist operators in recognizing and abating hazards likely to cause death or serious physical harm from the spread of SARS-CoV-2 (COVID-19) as part of their obligation to provide a safe and healthful mine.

Operators should implement COVID-19 Prevention Programs at each mine. Operators may consider a stand-alone program or additions to existing training and education programs. The most effective programs engage miners and miner representatives in the program’s development, and include the following key elements:

  • Conducting a hazard assessment of the mine site;
  • Identifying a combination of measures that limit the spread of COVID-19 in mine settings;
  • Adopting measures to ensure that miners who are infected or potentially infected are separated and sent home from the mine; and
  • Implementing protections from retaliation for miners who raise COVID-19-related concerns.

MNM Fatality – 2/22/21

On Feb. 22, 2021, a 26-year-old underground chute puller was fatally injured as a passenger of a rail-mounted locomotive when he was crushed between the deck of the locomotive and an overhead chute at a lead-zinc ore underground mine with 114 employees in Strawberry Plains, TN*.

Best Practices: 

  • Install controls such as rail stops at loading points, crossings, etc., where track equipment must stop. 
  • Install reflective signs or warning lights well in advance of low clearance areas to alert miners of the upcoming hazard.
  • Develop safe working procedures to avoid low clearance and pinch point areas.  Monitor workers to ensure these procedures are followed.
  • Always look in the direction the equipment is moving in, and keep all body parts within the operator’s compartment while a vehicle is moving.
  • Conduct proper travelway examinations to identify and mitigate the hazards presented by low clearances. 
  • Train all workers to recognize potential hazards and understand safe job procedures and tasks to eliminate hazards before beginning work.

Additional Information: 

This is the 4th fatality reported in 2021, and the third classified as “Powered Haulage.” *(details added by safeminers.com from MSHA data)

MNM Fatality – 2/8/21

On February 8, 2021, a 38 year old ground man* was fatally injured when he became entangled in a fluted tail pulley while attempting to shovel under an adjacent fluted tail pulley at a limestone min in Potosi, MO with 12 employees*.

Best Practices: 

  • Design, install, and maintain area guards with signage and locks in addition to the physical barrier.  Find more information on area guarding at https://www.msha.gov/guarding-slide-presentation-guarding-conveyor-belts-metal-and-nonmetal-mines.
  • Design and maintain secure guards so miners can perform routine maintenance on belt conveyor systems without contacting moving machine parts.
  • Do not perform work on a belt conveyor until the power is off, locked out and tagged, and machinery components are blocked against motion.
  • Never clean pulleys or idlers manually while belt conveyors are operating.
  • Establish policies and procedures for conducting specific tasks on belt conveyors.
  • Ensure that people assigned to work on belt conveyors are task trained, understand the associated hazards, and demonstrate safe work procedures before beginning work.
  • Ensure all new miners receive new miner training and task training.

Additional Information: 

This is the third fatality reported in 2021, and the second classified as “Powered Haulage.” *(details added by safeminers.com from MSHA data)
