WAC 296-807-18025   Use specific safety guards for vertical and angle grinders using Type 6 or Type 11 wheels.  

     You must:

     • Make sure the safety guard:

     – Covers the wheel's plane of rotation toward the operator for at least one hundred eighty degrees

     – Covers the side of the wheel toward the driving flange for at least one hundred eighty degrees

     – Has a skirt which is adjustable to within one-eighth inch of the plane of the surface of the wheel.

     • Make sure not to use a "revolving cup guard."

Note:

"Cup back bushings" do not substitute for safety guards.
