Dear Mr. Penake:
This is in further response to your letter dated April 5, 1983, concerning the guarding of flywheels on power presses.
The Occupational Safety and Health Administration's General Industry Standards 29 CFR 1910.219(b)(1) and (b)(1)(vi) require guarding of the press flywheel. Furthermore, the latter provision requires that flywheels above working areas be provided with guards of sufficient strength to contain the flywheel in the event of shaft or wheel mounting failure.
Reference to ANSI 815.1-1972, the current version of the source standard, rapidly demonstrates that structural failures are possible. Appendix AB.1 of ANSI 815.1 indicates that failures of a fatigue nature can be anticipated, particularly for older machines that have been continually exposed to cyclic leads. Therefore, substantial guarding is necessary to provide safety.
That company die setter's need to have easy access to the flywheel for die-setting for is completely valid and should be a major consideration of the guarding provided. In that regard, the guard configuration enclosed is recommended for consideration.
