Angle Grinder Hazard Awareness Training Presentation


The objective behind Angle Grinder Safety awareness PPT is to appropriately and essentially communicate the hazards related to angle grinders and the controls that should be in place for all workers who involved using this Angle Grinder. 

Grinding & Cutting Hazards


  1. Proper PPE {glasses, full face shield, hearing protection); 
  2. Proper clothing -100% cotton or FR;
  3. All PPE and clothing must be in good order and free of oil and grease;
  4. Areas must be free of combustibles;
  5. Control spark direction by being aware of your surroundings;
  6. Use proper barriers like guarding of the work area, fire blanket, welding curtain; 
  7. Burning permit as required.


  1. Identify required respiratory protection for work being performed {P-100 cartridge);
  2. If grinding on potential lead-based paint, refer to OH-OEMP-SPL-05 for required controls; 
  3. Proper ventilation of work area (i.e., or mover, or smoke eater);
  4. Free area of secondary dust that may be present in the work area or on equipment being worked on (i.e., vacuum area, wash down area, or sweep area);
  5. Remove excess dust on clothing after performing work (i.e., Damp cloth or vacuum); 
  6. Be aware of possible combustible dust material.


  • Be aware of workpiece finish which will create fumes {paints, oils, grease, solvents, galvanized); 
  • Proper ventilation;
  • Identify required respiratory protection for work being performed {stainless steel, aluminum, metal oxides, silica);
  • Plan work to properly remove hazardous surfaces before grinding {lead paint etc.).


  1. Identify the required level of hearing protection (e.g., Single or double protection); 
  2. Inform people who may be affected by your work;
  3. Participate in the hearing testing program.


  1. If grinding for extending periods, the use of vibration gloves recommended; 
  2. Inspect disks to prevent excessive vibration and replace as required;
  3. Secure work to prevent vibration;
  4. Inspect grinder for worn bearings or abnormal vibration.

Projectile Material

  1. Secure workpiece; Housekeeping in the work area;
  2. Be aware of the direction of grinding sparks and material. Other barriers/shields may be required;
  3. Be aware the process of grinding can dislodge material from the workpiece and become an airborne

Projectile Disk

  1. The guard on grinder must be properly secured and in the proper position to protect the user from projectiles from the disk;
  2. Never use excessive force to the grinder disk;
  3. Do not use a cutting disk to perform grinding work;
  4. Never bump the rotating grinder disk onto the workpiece;
  5. Keep the grinding disk at a 15 to 30-degree angle to the workpiece; 
  6. Wear all required PPE {glasses, face shield and gloves);
  7. Check that the disk speed marked on the disk is equal to or greater than the maximum speed of the grinder;
  8. Do not twist or bend a cutting disk in operation;
  9. Do not overtighten the knurled nut that secures the disk;
  10. Ensure that you are using the proper type of grinding or cutting disk for the workpiece.

Fractured Disk

  1. Check the condition of the disk before using the grinder;
  2. If any defects or fractures found, remove and discard disk;
  3. Use proper disk for application to prevent "glazing" thus resulting in disk overheating causing failure; 
  4. Do not abuse the disk.
  5. Grinding wrong material
  6. Make sure to use the proper disk for the material being cut or ground {plugged or glazed disk causes overheating resulting in failure or the premature wear of the disk.).

Kick Back

  1. Always use and never remove provided safety attachments {handle & guard); 
  2. Firm grip on the grinder and handle;
  3. Never let the grinder go until the disk has stopped; 
  4. Do not apply excessive force to the disk;
  5. Good work practices not overreach, do not use the grinder without both hands on the tool {handle & grinder), do not use the grinder in a cramped area when you do not have full control of the grinder.

Work Environment (wet conditions, fire hazards)

  1. Conduct a workplace inspection before starting work {are there any hazard that could put you at risk while grinding or what hazards are in the area when you grind);
  2. Hot work permit;
  3. Proper housekeeping practices;
  4. Proper barricade/barrier in place for the work being performed.

Heat Generation from Grinding

  1. The workpiece will be hot due to grinding {use proper PPE or tools when handling hot workpieces); 
  2. Sparks coming in contact with combustibles.

Changing Disks

  1. Disconnect power to grinder;
  2. Use proper tools for the removal of the retaining nut {if provided); 
  3. Follow manufactures instructions;
  4. Do not strike grinder disk to loosen;
  5. Use a locking device to an in the removal of the disk; 
  6. Use Proper PPE.

Freewheeling {letting of grinder before disk stops)

  1. Never put a grinder down while the disk is still rotating;
  2. Do not force shut down of disk with force, allow the disk to stop on its own.
