Grinder Safety
Portable Grinders
Stationary Grinders
Grinder Safety (I)
• Always get the instructors permission to
operate the grinding equipment
• Always wear safety glasses and a face shield
during operation
• Never wear loose clothing around this
machine while in operation
• Wear close-fitting gloves and a lab coat or
heavy shirt for protection
Grinder Safety (II)
• Small work pieces should be held by a vise while
using the portable grinder and with vise grips
while using the stationary grinder. If the pieces
are too small to handle they should not be
machined with a grinder.
• Check the grinding wheels to see if it is free of
any nicks, gouges, and cracks
• The tool rest helps position and guide materials
during operation. Make sure the tool rest is
adjusted 1/16” or less from the wheel
• Always hold the metal firmly on the tool rest
Grinder Safety (III)
• Always move the metal back and forth while
grinding unless specified by the instructor. This
ensures even wear on the grinding wheel.
• Always turn the stationary grinder off when
finished with an operation and wait for them to
come to a complete stop.
• Never walk or pass through the sparks while
grinding is taking place
• Never grind the weld sparks / debris into another
worker in the shop
Grinder Safety (IV)
• Always use the designed wrenches to change grinding
wheels on the portable grinders
• Always make sure all guards are in place and working
properly
• Never throw the portable grinder on the ground or into the
work
• Always make sure the portable grinder has come to a
complete stop before setting it down.
• Both hands are always on the portable grinder during
operation.
• Only use abrasive grinding wheels for the material they
were meant to machine. (Steel and Aluminum do not mix)
