The Mine Safety and Health Administration (MSHA) and the Kentucky Crushed Stone Association want to help improve the safety in the Metal - NonMetal Mining Industry. Here are some helpful best practices to keep you and your company safe:

1. Powered Haulage

  • Provide and maintain adequate berms or guardrails on the banks of roadways where a drop-off exists. 
  • Conduct pre-operational checks to identify and correct any defects that may affect the safe operation prior to operating mobile equipment. 
  • Always wear a seat belt when operating self-propelled mobile equipment. 
  • Maintain control of self-propelled mobile equipment while it is in motion. 
  • Operate mobile equipment at speeds consistent with the conditions of roadways, tracks, grades, clearance, visibility, curves, and traffic. 
  • Stay alert while operating mobile equipment. Ensure traffic rules, signals, and warning signs are posted and obeyed.  
2. Electrocution
  • Ensure that persons are trained on all electrical tests and safety equipment necessary to safely test and ground the circuit where work is to be performed. 
  • Positively identify the circuit on which work is to be conducted. 
  • De-energize power and ensure that the circuit is visibly open for circuits being worked on and circuits near the work area. 
  • Lock and Tag! Place YOUR lock and tag on the disconnecting device. 
  • Use properly rated Personal Protective Equipment (PPE) including Arc Flash Protection such as a hood, gloves, shirt, and pants. 
  • Ensure ALL electrical components in the enclosure are de-energized by testing for voltage using properly rated test equipment. 
  • Install warning labels on the terminal covers of bottom feed circuit breakers warning that "Bottom terminal lugs remain energized when the circuit breaker is open." 

3. Drowning

  • Task train all persons to recognize all potential hazardous conditions and ensure they understand safe job procedures for elimination of the hazards before beginning work. 
  • Always wear a life jacket where there is a danger of falling into the water. 
  • Remove snow and ice from work areas. 
  • Ensure safe access is provided where persons are required to work or travel. Maintain three points of contact. 
  • Install and use lifeline tie-off runs and fall protection. 
  • Provide communication devices and establish procedures requiring persons to alert coworkers when they are outside the dredge’s handrails. 
4. Fall
  • Immediately report any elevator problems to management. 
  • Ensure that any problems affecting the safety of an elevator are repaired promptly. 
  • Ensure that elevator door interlocks, that prevent the door from being opened unless the elevator car is present, are functional. 
  • Ensure that elevator doors will not open unless an elevator car is at the floor landing. 
  • Install audible signals that sound when the elevator car is at the landing prior to the doors opening. 
  • Train all persons to be aware of their surroundings when entering or exiting an elevator car 
5. Ignition/Explosion of Gas
  • Establish and discuss safe work procedures before beginning work. Identify and control all hazards associated with the work to be performed and use methods to properly protect persons. 
  • Train all persons to understand the hazards associated with the work being performed. 
  • Do not apply heat or open flame where enclosed spaces such as impeller hubs, mounted tires, suspension struts, or tanks may be subject to explosion except as directed by the manufacturer. 
  • Always examine materials before applying heat, cutting, or welding to ensure gases from the applied heat can vent. 
  • Never apply heat to materials before ensuring that flammables/combustibles/explosive materials are not present. 
  • Never apply heat to materials where pressure build up is possible. 
  • Do not apply heat or open flame where lubricants, oil, or grease are present. 
  • Use special tools, provided by the manufacturer, to loosen an impeller on a pump. 
  • Refer to the maintenance manual, warning labels on the pump, or contact the manufacturer for special safety precautions. 
6. Electrocution
  • Establish and discuss safe work procedures before beginning work. Identify and control all hazards associated with the work to be performed and use methods to properly protect persons. Train all persons to understand the hazards associated with working near energized electrical conductors.
  • De-energize power and ensure that the circuit is visibly open before working near energized conductors that may have damaged insulation.
  • Lock and Tag! Place YOUR lock and tag on the disconnecting device.
  • Use properly rated Personal Protective Equipment (PPE) including Arc Flash Protection such as a hood, gloves, shirt, and pants.
  • Ensure electrical conductors are properly rated and designed for the applications used. Ensure that all electrical systems are safely designed and properly installed. 
7. Powered Haulage
  • Task train all persons to stay clear of mobile equipment. 
  • Be aware of the location and traffic patterns of mobile equipment in your work area. 
  • Before moving mobile equipment, look in the direction of travel and use all mirrors and cameras to ensure no persons are in the intended path. 
  • Sound the horn to warn persons of intended movement and give them time to move to a safe location. 
  • Operate mobile equipment at reduced speeds in work areas. 
  • Ensure that backup alarms and lights on mobile equipment are maintained and operational. 
  • Ensure that haul truck operators remain in their trucks when mobile equipment is being operated nearby. 
  • Communicate with mobile equipment operators and ensure they acknowledge your presence. Stay in the line of sight with mobile equipment operators. Never assume the equipment operator sees you. 
  • Before operating equipment, always ensure other persons are clear and safely positioned.
