Grinder Safety


Regardless of the type of grinder being used, it is important to take the correct safety precautions. In addition to the appropriate safety measures, proper operation of the grinder, as with all tools, will also help to greatly reduce the likelihood of injury.

Grinders are powerful tools that spin very quickly so before grinding, all clothing should be secured and kept out of the way. Debris and sparks often fly off while working on a piece, so it is essential to have good eye protection with safety glasses or goggles. Wearing gloves will protect the hands from sparks and debris, and in some applications if excessive amounts of sparks are expected, fire retardant clothing should be worn.

Apart from sparks and debris, grinders are also loud and can reach very high decibels while being used on a work piece. Hearing protection such as ear plugs or headphones should be used to protect the ears. Furthermore, some applications may require the use of a paper respiratory mask or respirator. For example, abrasive cutting will generate dust, so if a vacuum attachment is not being used and lots of dust is created, protection for the respiratory system should be worn.

Proper operation of the grinder will help to ensure your safety. To avoid kickback, make sure the wheel spins away from sharp edges rather into them. Do not over tighten the spindle nut as this may cause damage to the flanges and wheel, and do not tamper with built-in guards. When grinding metal, keep a bucket of water and rag nearby in order to cool the metal and keep it from overheating you work on it. Additionally, do not use discs outside of their listed maximum RPM.
