(Optional) Perform grinding operations with a pedestal/bench grinder and/or portable/hand-held disc/angle grinder.

Performance should include following all required safety procedures and protocols to include

• undergoing safety instruction and testing prior to operating power tools, machinery, or equipment
• explaining hazards associated with grinding operations
  • high speed flying particles
  • dust or fume inhalation
  • kickback, fires, and explosions
  • electrical shock, cuts, and abrasions
  • ear damage resulting from noise
  • musculoskeletal disorders resulting from repetitive motion and awkward work positions
    
    
• inspecting tools and components prior to use and operating tools according to manufacturer instructions
• using the required PPE
• selecting the correct tools and equipment (e.g., ensuring the RPM [rotations per minute] rating of the disc/blade is higher than that of the angle grinder)
• applying safety procedures, guidelines, protocols, and manufacturer specifications (e.g., adjusting guards to deflect flying particles away from the operator; using an 180° guard between operator and wheel).

Process/Skill Questions:

• Where should angle grinders not be used?
• What can one do to ensure angle grinders are used safely?
• Why should grinders be checked for defective wheels, and frayed or damaged electrical cords?
• How does one perform a “ring test”?
• Why is it important to only replace accessories with those recommended by the manufacturer?
