Dear Mr. Flick:
This is in response to your letter of May 19, 1983, on behalf of Mr. Alfred J. Hoch III, regarding the safeguards of piece parts being worked on an outside diameter (O.D.) surface grinder.
The Occupational Safety and Health Administration (OSHA) standard that applies to the safeguarding of surface grinders is 29 CFR 1910.212, a copy of which is enclosed. 29 CFR 1910.212(a)(1) specifically stipulates that operators and employees in the work area be protected from rotating parts. Furthermore, 29 CFR 1910.212(a)(3)(ii) requires the protection of employees exposed to injury by hazards at a machine's point of operation.
Various methods are used to provide acceptable forms of safeguarding, and they are delineated in some detail by the American National Standards Institute in ANSI B11.9-1975, a portion of which is enclosed. A complete copy of the ANSI standard may be purchased from:
The American National Standards Institute, Inc. 1430 Broadway New York, New York 10018 Telephone: (212) 354-3363
Manufacturers generally produce their machines to meet or exceed the specifications of the applicable ANSI standard. OSHA does not regulate the manufacture of machines, but we do regulate their safe use by employees.
If we may be of further assistance, please contact me.
