What safety precautions should you follow when using abrasive wheels?
- Select the right wheel for the job. It is important for safety. A wheel is dangerous when used for work for which it was not designed. Booklets from wheel and machine manufacturers provide technical information on wheel selection and proper use.
- Use only wheels marked with the type of wheel and maximum speed in revolutions per minute (rpm).
- Inspect the wheel upon receipt.
- Examine the wheel for any signs of damage.
- Use "ring test" to check if the wheel is damaged. Ring tests do not apply to small wheels 10 cm (4 in.) diameter and smaller.
What is the "ring test?"
- The ring test is one way to check whether the wheel is cracked or damaged. Ensure the wheel is clean and dry. Tap wheels gently with a nonmetallic tool such as a plastic screwdriver handle for light wheels and a wooden mallet for heavy wheels. An undamaged wheel will emit a metallic ring. Reject any wheel that sounds dead or cracked.
How should you handle and store the abrasive wheels?
All abrasive wheels are fragile.
- Handle wheels carefully. Avoid dropping or bumping.
- Do not roll a wheel on its edge.
- Transport wheels in containers designed to provide support for the wheels if they are too heavy to carry by hand.
- Do not pile other items such as tools on top of wheels.
- Store wheels in racks or bins with dividers for different types of wheels and ensure easy access and less handling.
- Place straight or tapered wheels on end in a cradle or chocked position to prevent rolling.
- Never store wheels near excessive heat or cold, in contact with oil or moisture, or in drawers with loose tools.
- Sort and store wheels in such away that older wheels can be selected first.
- Follow the manufacturer's instructions for length of time a wheel should be stored and how to store thin wheels.
