Appendix A.  

The purpose of the certification/validation of safety systems for presence sensing device initiation (PSDI) of mechanical power presses is to ensure that the safety systems are designed, installed, and maintained in accordance with all applicable requirements of sections 4192 through 4211 and this Appendix A.

The certification/validation process shall utilize an independent third-party validation organization recognized by the U.S. Labor Department, Occupational Safety and Health Administration (OSHA) in accordance with the requirements specified in Appendix C of paragraph (h), 29 CFR 1910.217, revised March 14, 1988 which is hereby incorporated by reference.

While the employer is responsible for assuring that certification/validation requirements in section 4208.1(k) are fulfilled, the design certification of PSDI safety systems may be initiated by manufacturers, employers, and/or their representatives. The term “manufacturers” refers to the manufacturer of any of the components of the safety system. An employer who assembles a PSDI safety system would be a manufacturer as well as employer for purposes of section 4208.1 and this Appendix A.

The certification/validation process includes two stages. For design certification, in the first stage, the manufacturer (which can be an employer) certifies that the PSDI safety meets the applicable requirements of sections 4192 through 4211 and this Appendix A, based on appropriate design criteria and tests. In the second stage, the Division-recognized third-party validation organization validates that the PSDI safety system meets the applicable requirements of sections 4192 through 4211 and this Appendix A and the manufacturer's certification by reviewing the manufacturer's design and test data and performing any additional reviews required by sections 4192 through 4211.

For installation certification/validation and annual recertification/revalidation, in the first stage, the employer certifies or recertifies that the employer is installing or utilizing a PSDI safety system validated as meeting the applicable design requirements of sections 4192 through 4211 and this Appendix A by a Division-recognized third-party validation organization and that the installation, operation and maintenance meet the applicable requirements of sections 4192 through 4211 and this Appendix A. In the second stage, the Division-recognized third-party validation organization validates or revalidates that the PSDI safety system installation meets the applicable requirements of sections 4192 through 4211 and this Appendix A and the employer's certification, by reviewing that the PSDI safety system has been certified; the employer's certification, designs and tests, if any; the installation, operation, maintenance and training; and by performing any additional tests and reviews which the validation organization believes is necessary.

The certification/validation of safety systems for PSDI shall consider the press, controls, safeguards, operator, and environment as an integrated system which shall comply with all of the applicable requirements in sections 4192 through 4211 and this Appendix A. The certification/validation process shall verify that the safety system complies with the safety requirements as follows:

A. Design Certification/Validation.

. The total system design shall be certified by the manufacturer as complying with the applicable requirements in sections 4192 through 4211 and this Appendix A.
