Dear Mr. Clouse:
Your letter dated January 20, 1977, addressed to the President, has been referred to this office for reply.
The point of operation hazard on power press brakes has been evident for many years. The hazard has left hundreds of employees with handicaps from severed hands, arms and in many cases resulted in death when other parts of the body were caught in the point of operation.
As you know, the only way to completely eliminate the point of operation exposure to employees is to fully enclose the danger area with a fixed barrier guard. This type of guard prevents them from placing any part of their bodies into the point of operation but in many cases interferes with the operation to a degree that production is impractical.
The Occupational Safety and Health Administration (OSHA) recognized this problem and provided more than one method of safeguarding in 29 CFR 1910.212 of the Safety Standards for General Industry (copy enclosed). In addition, an OSHA Program Directive (PD) #100-44 (Revision #1)(copy enclosed), dated October 26, 1976, was issued to clarify the guarding requirements.
One of the many acceptable methods of safeguarding is the electric light curtain or electric eye, providing that it is located far enough away to stop the machine before an employee can reach into the point of operation. The installation of the electric eyes was apparently the decision of your employer to provide you with the best possible protection.
Hopefully, this information will be helpful to you and your fellow employees. If I may be of any further assistance, please feel free to contact me.

Deputy Assistant Secretary of Labor
