Rack Safety Assessment Guidelines
The 1-2-3 Rule
Use the 1-2-3 rule to determine if a deflection on an upright should be addressed.
1. UPRIGHTS FRONTAL
Over 1/8" of frontal deflection within a span of 40"
Deflection > 1/8"
Look for other types of damage, such as dents, cracks, bulges, pinched columns, and signs of corrosion.
2. UPRIGHTS LATERAL
Over 2/8" of lateral deflection within a span of 40"
Deflection > 2/8"
Look for damage occasionally hidden behind the beam connectors.
3. BRACES HORIZONTAL & DIAGONAL
Over 2/8" of lateral deflection within a span of 40"
Deflection > 3/8"
Look for cracked or broken welds between the column and the brace.
BRACES
Horizontal and diagonal braces are essential to the capacity and stability of the rack.
TWISTED COLUMNS
Twisted columns impede the load capacity of the rack. We recommend calling an expert.
ANCHORING
Shims should be well seated, secured, and of equal size to the footplate.
HOMEMADE REPAIRS
Any homemade or welded repairs should be replaced by an engineered repair solution.
BEAMS
Look for deflected, damaged, unclipped, or overloaded beams, missing safety bars, badly positioned, or damaged pallets.
BEAM CONNECTORS
Look for corrosion, deformations, cracks in the welds, broken connectors, or missing safety pins.
OUT-OF-PLUMB
An out-of-plumb upright means that it is not exactly vertical. Always look in the cross-aisle and down-aisle directions.
LOAD CAPACITY
Labels informing of maximum load capacity should be visible. The unknown load capacity needs to be calculated by an engineer.
