Believe it or not, abrasive wheels have legal speeds.
This means if your employees use this type of equipment, they must adhere to the following:
Five rules for legal speeds of abrasive wheels
Rule #1: Maximum speed in revolutions per minute (rpm) is marked on every wheel. Never exceed this speed.
Rule #2: Check that the wheel speed marked on the wheel is equal to or greater than the maximum speed of the grinder.
If it isn't, choose a different wheel where the speed rating is higher than the spindle speed.
Rule #3: Measure the speed of any new machine. Take several readings to be sure.
Rule #4: Measure the speed of governor controlled air driven grinders after 20 hours of use or every week, whichever comes first. Also measure speed after any repairs. This isn't a legal requirement, but it's a good safety measure.
Rule #5: Measure the speed of electrically-driven grinders monthly and after repairs.
In addition to this, make sure your employees know how to handle abrasive wheels safety.
Here are three tips for handling abrasive wheels
The Health & Safety Advisor says all abrasive wheels are fragile. So, your employees must:
Tip #1: Handle wheels carefully. Avoid dropping or bumping them. This may cause the wheel to sustain a crack which will cause it to shatter when it turns at speed.
Tip #2: Have a soft surface (for example, rubber mats) to roll wheels on if they can't carry them.
Tip #3: Transport wheels in cardboard or wooden containers with compartments to separate and support the wheels
Abrasive wheels are dangerous. Make sure your employees stick to the rules for legal speeds when using them.
