According to OSHA, all floor and bench mounted abrasive grinders with cup type wheels used for external grinding must be provided with all of the following safety devices EXCEPT:

• A. steel mandrels
• B. a revolving cup guard or band type guard
• C. a protective hood
• D. rigidly supported and adjustable work rests

Answer: (A)

OSHA emphasizes guarding and stable support to protect the operator during external grinding. The required safety features are a guard that encloses the wheel (such as a revolving cup guard or band-type guard), a protective hood to shield the grinding area, and a work rest that is rigidly supported and adjustable to keep the workpiece properly positioned and prevent wheel contact or kickback. A steel mandrel, while it can be part of wheel mounting hardware, isn’t a safety device mandated for external grinding under OSHA standards; it’s a mounting component rather than a guarding or protective feature. So the steel mandrel is the item that isn’t required as a safety device.
