RHS - Pedestal Grinder Safety Test

The proper spacing for the tool rest on the pedestal grinder is:

• 1/4 inch

• 1/2 inch

• 3/4 inch

• As close as possible without touching the wheel

The student must wear safety glasses or face shield while operating the grinder because:

• Flying sparks or grit may cause injury to the student

• It enables the operator to see the work more clearly

• It alerts others that the grinder is going to be used

• The teacher will be really mad if you don't

For a grinder with 2 grinding wheels, the number of students who can safeley operate the grinder is:

• One

• Two

• Three

• None of the above

When watching someone who is using the pedestal grinder:

• Don't distract them form their work

• Allow them plenty of work space

• All the above

Grind only on the ___________ of the grinding wheel, never on the side.

• Corner

A student should stand to one side of the grinding wheel when turning it on because:
