The inspection must meet all of the following requirements:
(i) The inspection must assure that the modifications or additions have been done in accordance with the approval obtained pursuant to § 1926.1434 (Equipment modifications).
(ii) The inspection must include functional testing of the equipment.
(2) Equipment must not be used until an inspection under this paragraph demonstrates that the requirements of paragraph (a)(1)(i) of this section have been met.
(b) Repaired/adjusted equipment. (1) Equipment that has had a repair or adjustment that relates to safe operation (such as: A repair or adjustment to a safety device or operator aid, or to a critical part of a control system, power plant, braking system, load-sustaining structural components, load hook, or in-use operating mechanism), must be inspected by a qualified person after such a repair or adjustment has been completed, prior to initial use. The inspection must meet all of the following requirements:
(i) The qualified person must determine if the repair/adjustment meets manufacturer equipment criteria (where applicable and available).
(ii) Where manufacturer equipment criteria are unavailable or inapplicable, the qualified person must:
(A) Determine if a registered professional engineer (RPE) is needed to develop criteria for the repair/adjustment. If an RPE is not needed, the employer must ensure that the criteria are developed by the qualified person. If an RPE is needed, the employer must ensure that they are developed by an RPE.
(B) Determine if the repair/adjustment meets the criteria developed in accordance with paragraph (b)(1)(ii)(A) of this section.
(iii) The inspection must include functional testing of the repaired/adjusted parts and other components that may be affected by the repair/adjustment.
(4) Equipment must not be used until an inspection under this paragraph demonstrates that the repair/adjustment meets the requirements of paragraph (b)(1)(i) of this section (or, where applicable, paragraph (b)(1)(ii) of this section).
(c) Post-assembly. (1) Upon completion of assembly, the equipment must be inspected by a qualified person to assure that it is configured in accordance with manufacturer equipment criteria.
(2) Where manufacturer equipment criteria are unavailable, a qualified person must:
(i) Determine if a registered professional engineer (RPE) familiar with the type of equipment involved is needed to develop criteria for the equipment configuration. If an RPE is not needed, the employer must ensure that the criteria are developed by the qualified person. If an RPE is needed, the employer must ensure that they are developed by an RPE.
(ii) Determine if the equipment meets the criteria developed in accordance with paragraph (c)(2)(i) of this section.
(3) Equipment must not be used until an inspection under this paragraph demonstrates that the equipment is configured in accordance with the applicable criteria.
(d) Each shift. (1) A competent person must begin a visual inspection prior to each shift the equipment will be used, which must be completed before or during that shift. The inspection must consist of observation for apparent deficiencies. Taking apart equipment components and booming down is not required as part of this inspection unless the results of the visual inspection or trial operation indicate that further investigation necessitating taking apart equipment components or booming down is needed. Determinations made in conducting the inspection must be reassessed in light of observations made during operation. At a minimum the inspection must include all of the following:
(i) Control mechanisms for maladjustments interfering with proper operation.
(ii) Control and drive mechanisms for apparent excessive wear of components and contamination by lubricants, water or other foreign matter.
(iii) Air, hydraulic, and other pressurized lines for deterioration or leakage, particularly those which flex in normal operation.
