(52) Stop control means an operator control designed to immediately deactivate the clutch control and activate the brake to stop slide motion. (ix) If foot control is provided, the selection method between hand and foot control shall be separate from the stroking selector and shall be designed so that the selection may be supervised by the employer. This appendix prescribes mandatory requirements and procedures for OSHA recognition of third-party validation organizations to validate employer and manufacturer certifications that their equipment and practices meet the requirements of the PSDI standard. (9) Repairs and maintenance. All power-transmission equipment shall be inspected at intervals not exceeding 60 days and be kept in good working condition at all times. Pulleys with cracks, or pieces broken out of rims, shall not be used. Toeboards shall be four (4) inches or more in height, of wood, metal, or of metal grill not exceeding one (1) inch mesh.

(i) Limitations: Special supporting, back adapter and inside flange nuts are required for the proper mounting of these types of wheels subject to limitations of 1910.215(c)(4) (i) and (ii). In all other industries, wood guards shall not be used. (x) All components and subsystems of the control system shall be designed to operate together to provide total control system compliance with the requirements of this section. 1910.112-1910.113 [Reserved] broken springs). 3. The label shall indicate the press serial number, the minimum safety distance (Ds) required by paragraph (h)(9)(v) of this section, the fulfillment of design certification/validation, the employer's signed certification, the identification of the OSHA-recognized third-party validation organization, its signed validation, and the date the certification/validation and recertification/revalidation are issued. 1910.29 Fall protection systems and falling object protectioncriteria and practices. (i) Presses with flexible steel band brakes or with mechanical linkage actuated brakes or clutches shall not be used in the PSDI mode. (1) Flywheels. This table technically only applies to mechanical power presses operated within OSHA's jurisdiction, although some industry consensus standards also reference this table, such as ANSI B65.1 . The diameter of circular shaper guards shall be not less than the greatest diameter of the cutter.
