According to OSHA grinding regulations, grinding machines must have safety guards. A guard must cover the machine39s 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
Floor stand and bench mounted abrasive wheels used for external grinding shall be provided with safety guards protection hoods. The maximum angular exposure of the grinding wheel periphery and sides shall be not more than 90 degrees, except that when work requires contact with the wheel below the horizontal plane of the spindle, the angular exposure shall not exceed 125 degrees.

Grinding wheels on floor stands, pedestals, benches, and specialpurpose grinding machines and abrasive cuttingoff wheels shall have not less than the minimum exhaust volumes shown in Table D57.1 with a recommended minimum duct velocity of 4,500 feet per minute in the branch and 3,500 feet per minute in the main.
The Occupational Safety and Health Administration OSHA is very specific about bench grinder safety. OSHA refers to bench grinders as Abrasive Wheel Equipment Grinders. The safety rules for this machinery are in the Code of Federal Regulations CFR, and OSHA has a very detailed checklist for the bench grinder on its website.
Administration39s OSHA standards regarding abrasive wheels and tools 29 CFR 1926.303. 1. Preparation Remove flammable materials from the work area. Ensure work area is clean, free from slip, trip, and fall hazards and well maintained. Keep the power cord away from the grinding wheel and the material being ground.
It is based on the premise that grinding is a safe operation when a few basic rules are followed. These rules are based on material contained in the American National Standards Institute Safety Requirements B7.1 Use, Care amp Protection of Abrasive Wheels. Follow them.

Use the correct wheel for the machines size and speed, and the work to be performed. A cutting disc should not be used for grinding. The RPM rating of the discblade must be higher than that of the angle grinder. Adjust guards to deflect flying particles away from operator. Use an 180 guard between operator amp wheel.
ANSI B7.1 has been called the Bible for grinding wheel safety for good reason. It is the abrasive grinding wheel industry standard for the Safety Requirements for the Use, Care and Protection of Abrasive Wheels and most abrasive wheel safetyrelated questions can be found there.
Bring work into contact with the grinding wheel slowly and smoothly, without bumping. Apply gradual pressure to allow the wheel to warm up evenly. Use only the pressure required to complete a job. Move the work back and forth across the face of the wheel. This movement prevents grooves from forming. Wheels are made only for grinding certain items.
Abrasive wheels shall be used only on machines provided with safety guards as required in Section 3577b. b A safety guard shall cover the spindle end, nut and flange projections. The safety guard shall be mounted so as to maintain proper alignment with the wheel, and the strength of the fastenings shall exceed the strength of the guard.
