(10) SECTiON 20-0.2: DEFINITIONS — GENERAL
adrninistratit’e or regulatory autlwrity: governmental agency, or the employer in the absence of governmental jurisdiction.
alteration: a physical change, addition, or deletion that modifies the original design, or intended functioning, of the below-the-hook lifting device.
altered: see alteration.
appointed: assigned specific responsibilities by the employer or the employer’s representative.
authorized: appointed by a duly constituted administrative or regulatory authority.
below-the-hook liftinç device: a device used for attaching loads to a hoist. The device may contain components such as slings, hooks, and rigging hardware addressed by other ASME B30 volumes or other standards.
design category: lifter classification that specifics the design factor to be used to establish static stress limits for the design.
designated person: a person selected or assigned by the employer or the employer’s representative as being competent to perform specific duties.
(d) Special or infrequent service — as recommended by a qualified person before and after each occurrence
(3) Periodic Inspection. Visual inspection by a qualified person making records of apparent external conditions to provide the basis for a continuing evaluation. An external code mark on the lifter is an acceptable identification in lieu of records.
(a) Normal service for equipment in place — yearly
(b) Heavy service las in (a) above, unless external conditions indicate that disassembl should be done to permit detailed inspectionl — semiannually
(c) Severe service [as in (b) above] — quarterly
(1) Special or infrequent service — as recommended by a qualified person before the first such occurrence and as directed by the qualified person for any subsequent occurrences
20-1.3.2 Every Lift Inspection
Items such as the following shall be inspected by the operator before and/or during every lift for any indicaI ion of damage as specifically indicated, including observations during operation for any damage that might occur during the lift:
(a) surface of the load for debris
(b) condition and operation of the controls
(c) condition and operation of the indicators and meters when installed
20-1.3.3 Frequent Inspection (See Also Table 1)
Items such as the following shall be inspected for damage at intervals as defined in para. 20-1.3.1(b)(2), including observations during operation for any indications of damage that might appear between inspections. A qualified person shall determine whether any indications of damage constitute a haiard or will require more frequent inspection. For all lifters, inspect
(a) structural members for deformation, cracks, or excessive wear on any part of the lifter
(b) loose or missing guards, fasteners, covers, stops, or nameplates
(c) all functional operating mechanisms and automatic hold-and-release mechanisms for misadjustments interfering with operation
20-1.3.4 PerIodic Inspection (See Also Table 1)
Complete inspection of the lifter shall be performed at intervals as defined in para. 20-l.3.l(b)(3). Any deficiencies, such as listed below, shall be examined and determination made as to whether they constitute a hazard. These inspections shall include the requirements of para. 20-1.3.3 and, in addition, items such as the following:
(a) loose bolts or fasteners.
