Grinding wheels on floor stands, pedestals, benches, and special-purpose grinding machines and abrasive cutting-off wheels shall have not less than the minimum exhaust volumes shown in Table D-57.1 with a recommended minimum duct velocity of 4,500 feet per minute in the branch and 3,500 feet per minute in the main.
Jul 20, 2017 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 within 1/8-inch of the wheel.
OSHA Training Toolbox Talk: Operating a Pedestal or –Bench Grinder Basic Safety Requirements [Reference 1910.215 / 1926.303] Can you believe the surface of an eight-inch diameter grinding wheel that is mounted on a bench grinder turning 3,100 RPM’s is traveling at …
Sep 04, 2013 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 safety-related questions can be found there.
Are all floor- and bench-mounted abrasive wheels equipped with safety guards? [29 CFR 1910.215(a)(1) and 1926.303(a)] Does the safety guard cover the spindle end, nut, and flange projections? [29 CFR 1910.215(a)(2)] Is the maximum angular exposure of the grinding wheel and sides 90 or less?
American National Standards Institute • ANSI B7.1, Safety Code for the Use, Care, and Protection of Abrasive Wheels • ANSI B11.9, Safety Requirements for Grinding • Proper exposure angle (90 degrees) • Adjustable tongue guards (1⁄4-inch) • Adjustable tool/work rest (1⁄8-inch) Plastic glass (Plexiglas) shields are optional.
May 31, 2021 Right-angle grinder - the grinding face of the wheel or disc is at an angle of between 5 and 15 degrees from the grinding surface. 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.
Jun 02, 2017 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 two groups which initiated the Code in 1917 have been expanded into a Standards Committee representing nationally recognized engineering, safety, abrasive wheel and grinding machine fabricators and user associations, labor organizations, insurance underwriter groups, and several interested government agencies.

Mar 01, 2017 Grinder safety gauges can be used during the installation, maintenance, and inspection of bench/pedestal grinders to ensure work-rests and tongue-guards comply with OSHA’s 1910.215 regulation and ANSI standards. To do so, wait until the wheel has completely stopped and the grinder is properly locked out before using a grinder safety gauge.
Apr 08, 1994 English. Labels and stickers. Prevent accidents for abrasive wheel machinery and tools. Prevent accidents: Adjust the distance between the grinding wheel and the tongue guard to a 1/4 inch maximum and the distance between the grinding wheel and the work rest to a 1/8 inch maximum.
