OSHA 29 CFR SubPart O 1910.215 for bench grinders is one of the most frequently cited machine-safety standards for violations during OSHA inspections, and one of the most dangerous to ignore. OSHA 1910.215 is a "machine specific" (vertical) regulation with a number of requirements, which if left unchecked, are often cited by OSHA as violations.
According to OSHA grinding regulations, grinding machines must have safety guards. A guard must cover the machine's spindle end, flange projections and nut and have secure mounting that keeps it in line with the grinding wheel. Guards must also protect workers from the grinding wheel; workers should only be exposed to 90 degrees (75 percent) or ...

Concrete grinding and concrete polishing are abrasive actions – they shape surfaces and materials by way of friction. So, there are numerous dangers at play when workers grind and polish. OSHA requires the following PPE when working with abrasives: Hearing protection. Face and eye protection like face shields.
Vertical grinder - the grinding wheel face is in contact with the surface. Use racks or hooks to store portable grinders. Stand away from the wheel when starting grinders. Warn co-workers to do the same. Inspect all wheels for cracks and defects before mounting. Perform a " ring test " to check if the wheel is damaged.
Ensure tool rest and tongue guard meet spacing requirements before starting an operation. [FED/OSHA 1910.215, CAL/OSHA §3577] Ring test and visually inspect all grinding wheels before they are mounted. [FED/OSHA 1910.215, CAL/OSHA §3580] Verify that the maximum RPM rating of each abrasive wheel meets or exceeds the grinder RPM.

The thickness of a grinding wheel impacts its performance and wheel life. Our grinding wheels typically come with a quarter-inch thickness. This measurement gives our wheels a superior balance of precision, wheel life, and cut-rate when grinding. Combination grinding and cutting wheels with 1/8-inch thickness are also available.
The angular exposure of the grinding wheel periphery and sides for safety guards used on machines known as bench and floor stands should not exceed 90 degrees or one-fourth of the periphery. This exposure shall begin at a point not more than 65 degrees above the horizontal plane of the wheel spindle. (See Figure A-1 of Appendix A.)
