OSHA requirements are set by statute, standards and regulations. Our interpretation letters explain these requirements and how they apply to particular circumstances, but they cannot create additional employer obligations. This letter constitutes OSHA's interpretation of the requirements discussed. Note that our enforcement guidance may be affected by changes to OSHA rules. Also, from time to time we update our guidance in response to new information. To keep apprised of such developments, you can consult OSHA's website at http://www.osha.gov.

Dear Mr. Leuschner:

This is in response to your letter of February 13 to Mr. Donald Shay in which you requested our opinion as to the conformance of the Blue Line PFR/Power Failure Release Option with applicable Occupational Safety and Health Administration (OSHA) standards.

The performance specification of 29 CFR 1910.213(b)(3) requires that woodworking machines be equipped with automatic power interrupters to avert hazardous employee exposures resulting from equipment restart when power is restored. It appears that the product offered by your company permits compliance with this OSHA standard, but whether or not your product would fully meet the conditions as stated in 29 CFR 1910.213 would depend upon its application.

Alteration or misapplication of an otherwise safe piece of equipment could create a hazardous condition beyond the control of the manufacturer. Therefore, compliance with our standards can only be determined when related to the specific circumstances of its use.

A further OSHA requirement pertaining to protection from the hazards of equipment restart after power interruption can be found in 29 CFR 1910.217(b)(8)(iii). In addition to OSHA requirements pertaining to power interruption protection, the American National Standards Institute (ANSI) recommends such protection for most machine tools specified by the ANSI Bill series of documents. ANSI may be contacted at:
