ASME B30.9 recognizes three primary categories of rigging inspections, and OSHA adds a per-shift requirement that overlaps with the frequent category.
- First is the initial inspection, which must be performed on all new, repaired, or modified equipment before it is ever placed into service.
- Second is the frequent inspection, a visual check performed each day or shift the equipment is used. OSHA 1926.251 requires a competent person to examine all slings and fastenings prior to each shift, which aligns with this category. No formal records are required for frequent inspections.
- Third is the periodic inspection, a thorough, documented examination required at least annually by ASME B30.9 standards, sometimes supplemented by specialized nondestructive testing to detect hidden wear or structural degradation.
Adhering strictly to these inspection phases ensures lifting reliability, prevents catastrophic failures, and keeps your crew safe during complex operations.
