Presence Sensing Device Initiation (PSDI) Standard (29 CFR 1910.217(h))

Regulation 29 CFR 1910.217(h) regulates the use of Presence Sensing Devices (PSDs) in mechanical power-press safety systems. A PSD (e.g., a photoelectric field or curtain) automatically stops the stroke of a mechanical power press when the device detects an operator entering a danger zone near the press. The PSD initiation standard contains a number of information collection requirements, including: certifying brake monitor adjustments, alternatives to photoelectric PSDs, safety system design and installation, and worker training; annual recertification of safety systems; establishing and maintaining the original certification and validation records, as well as the most recent recertification and revalidation records; affixing labels to test rods and to certified and recertified presses; and notifying an OSHA-recognized third-party validation organization when a safety system component fails, the employer modifies the safety system, or a point-of-operation injury occurs.
