MEMORANDUM FOR: DAVID H. RHONE
                Regional Administrator

THRU:           DONALD E. MACKENZIE Field Coordinator

FROM:           RICHARD P. WILSON Deputy Director Federal Compliance and
                State Programs

SUBJECT:        Compression Springs Requirements, 29 CFR 1910.217(b)(3)(ii)
                and 29 CFR 1910.217(b)(4)(iii)

This is in response to your letter of September 28, 1977, regarding a request for comments and guidelines concerning the use of tension springs in lieu of the required compression springs on power presses. It further confirms discussions between Mr. Nunez and Mrs. Preston on this subject.

Our research reveals that the requirement originated years ago in the National Consensus Standard with the theory that compression springs are more reliable than tension springs. However, there are no documents available to support this requirement.

In view of the fact that the standard requirements for compression springs are not supported and the tension springs appear not to present a hazard, the employer has complied with the intent of the standards. Therefore, the situation would be considered a de minimis violation.

A copy of your correspondence and this response are being forwarded to the Directorate of Safety Standards Programs for information purposes.
