Wheels should have an RPM rating that matches the RPM rating of the grinder motor. Use the correct type of wheel for the material you are grinding. Store wheels so that they are not subject to the environment or damage. Guarding is extremely important for safe grinder operation. Side guards should cover the spindle, nut, flange and wheel.
The maximum angular exposure of the grinding wheel periphery and sides shall be not more than 90 deg, except that when work requires contact with the wheel below the horizontal plane of the spindle, the angular exposure shall not exceed 125 deg. In either case, the exposure shall begin not more than 65 deg. above the horizontal plane of the spindle.
wheel. Before use inspect wheelsfor cracks, defects and wear. Replace worn discs. Perform ring test as appropriate. Allow grinder to come to full speed and warm up to a complete stop after use. Do not grind on the side of the wheel. Do not use liquid coolants. Always use two hands. Keep hands away from rotating wheel and avoid continuous vibration.
Section 8 defines the requirements for wheels that are rated for speeds above the standard speed allowed in Section 7. If you need a grinding wheel to operate at higher than standard speeds there must be coordination between the wheel manufacturer, the machine supplier and the end user.
Some of the wheel must be exposed to allow grinding access, but the maximum access space between the horizontal work rest and the top of the wheel guard opening should be no more than 65 degrees of the wheel. The horizontal work rest should be adjusted to
OSHA, ANSI and the grinding wheel manufacturers require this method of grinding wheel inspection. It must be performed BEFORE the wheel is mounted on a grinding machine. Ring testing depends on the damping characteristics of a cracked wheel to alter the sound emitted when the wheel is tapped lightly.

(2) Grinding wheels shall fit freely on the spindle and remain free under all grinding conditions. A controlled clearance between the wheel hole and the machine spindle (or wheel sleeves or adaptors) is essential to avoid excessive pressure from mounting and spindle expansion.
Limitation: Hole dimension (H) should not be greater than twothirds of wheel diameter dimension (D) for precision, cylindrical, centerless, or surface grinding applications. Maximum hole size for all other applications should not exceed onehalf wheel diameter.
Abrasive Wheels are a commonly used tool in the construction trades. This page will detail the controlling Abrasive Wheels regulations and legislation. It will also detail the Abrasive Wheels training requirements. Abrasive Wheels Regulations. Abrasive Wheels are regulated by the Provision and Use of Work Equipment Regulations act 1998 (PUWER).
Before workers use a grinding wheel, OSHA regulations state that it should undergo an inspection to make sure that it does not have any cracks or defects. Protective Equipment Employees using grinders must wear goggles or face shields to protect themselves from flying particles, according to

Do not crowd the wheel to the point that it slows. Do not grind on the side of the wheel. Do all work on the face or edge near the rest. Make sure all eye equipment has no smudges or scratches blocking your view of the work. Do not wear loose clothing or other articles the wheel could catch,, name badges, shirttails or sleeves, or jewelry.
