Angle Grinder Safety

Angle grinders are often used to cut or remove unwanted fragments from metal. The discs rotate at tremendous speeds between 5,000 to 12,000 rotations per minute.

The most common causes of angle grinder injuries include lacerations from angle grinder kickbacks and projectiles from broken attachments.

These injuries are often caused by improperly maintained equipment, not using appropriate personal protective equipment, or improper use. Implement these safe practices when using angle grinders:

  • Always wear safety glasses or goggles and a face shield to protect against flying particles and projectiles. Other forms of PPE such as respirators, tight-fitting gloves, and hearing protection should be worn when applicable.
  • Keep bystanders away from the work area. If bystanders are in the vicinity, they should wear appropriate eye protection.
  • Do not wear loose clothing, hanging jewelry, bracelets, and long hair should be tied back.
  • Never operate the equipment without the guard in place.
  • Inspect the wheel for cracks and defects before use. Never use damaged or cracked wheels or those that vibrate excessively.
  • Inspect the power cord for damage and repair or replace as needed.
  • Use both hands when operating the grinder.
  • Allow the unit to reach full speed before grinding. Avoid grinding near flammable and combustible materials.
