Purpose

This procedure establishes a systematic method for detecting structural deflection and damage in pallet racking systems. Regular inspections prevent catastrophic collapse, protect inventory, and ensure worker safety in compliance with provincial regulations. Documented inspections also provide legal traceability and insurance support.

Scope

Applies to all adjustable pallet racking, drive-in racking, and push-back rack systems within the facility. Includes upright frames, beams, bracing, anchor bolts, baseplates, and beam connectors. Excludes automated storage/retrieval systems (covered under separate CMMS SOP). Inspections are to be performed monthly with a full annual engineering assessment.

Safety Precautions

LOTOLockout/tagout all powered material handling equipment (forklifts, VNA trucks) in the aisle under inspection. Verify with a zero-energy state.
PPEWear hard hat, steel-toed boots, high-visibility vest, and safety glasses. When inspecting beams above 2.4 m, use a fall arrest harness and approved ladder or scissor lift.
ACCESSErect temporary barricades or safety cones to prevent entry by untrained personnel while inspection is in progress.
LOADRemove all product from the rack section being inspected if beam connection or baseplate integrity is questionable. Do not work under loaded racks with known damage.

Required Tools & Materials

Plumb bob or laser level (accuracy ±0.5 mm/m)
Straightedge (2 m / 6 ft minimum)
Tape measure (metric and imperial graduations)
Torque wrench (calibrated, with rack manufacturer bolt specs)
Inspection form (paper or digital tablet with SafeDesk app)
Red paint marker or warning tags for damaged areas
Safety harness and lanyard (if elevated work)
Manufacturer load placards and rack layout drawings

Procedure: Step-by-Step

1 Review rack layout drawings and manufacturer load placards. Confirm accessibility for all aisles and rack uprights. Notify shift supervisor of inspection schedule.

2 Don required PPE and perform LOTO on any automated equipment in the aisle. Erect barricades and post warning signs.

3 Visually inspect each upright for verticality using a plumb bob or laser level. Measure deviation at top of frame. Record if more than 1:200 (0.5% of height).

4 Check horizontal and diagonal bracing for loose/missing bolts, dents, or bending. Use torque wrench to verify bolt tension per manufacturer’s torque table. Tighten or replace if needed.

5 Inspect beam connectors – look for visible gaps between beam and upright. Check that safety clips are present and not deformed. Replace any beam that does not seat fully.

6 Examine all anchor baseplates. Measure lifting at floor using straightedge. Any gap > 2 mm or visible concrete spalling requires engineering evaluation. Tag area and restrict access.

7 Document all deflection, damage, or anomalies per the inspection report. Use red paint marker to clearly tag unsafe frames. Photograph each issue for the log.

8 Forward completed report to safety supervisor and rack manufacturer representative for remedial action. Re-inspect after repairs within 30 days.
