To ensure the integrity of your pallet rack systems, it’s essential to understand the various types of damage that can be found on racks and their components. If you’ve seen damage in your warehouse, you might wonder: is it bad? How bad?

Pallet rack damage priority classification

Racking damage classification is necessary to ensure that rack damage and issues identified during inspections are appropriately addressed to prevent any opportunity for racking failure. The following is a brief review of the different damage priorities and a classification system used to communicate findings after a baseline audit or rack inspection.

Remember that this information should be used as supplemental guidance, as tolerance for damage or risk varies from company to company. It is certainly not intended to replace the advice of a professional rack specialist or engineer.

A holistic approach to rack inspections

When conducting inspections, one must look at the racking systems as a whole. Damage is rarely an isolated issue because racks are systems with various components that all rely on each other to support stored merchandise. Consequently, one must consider the height, the load capacity, the types of loads stored, the warehouse environment, the floor on which it stands, etc. If you think the damage may be critical or you have doubts about its severity, it’s always best to unload this part of the rack and speak to a racking specialist or a qualified engineer.

 

Rack damage weakens the system and can pose serious hazards

If the rack hasn’t collapsed, it doesn’t mean the damage is not significant or that it won’t happen! At worst, rack failure can lead to a partial or full collapse of the pallet racking system, resulting in falling objects and stored merchandise, damage to the property, or serious injury to workers.

Understanding issue priority levels and rack damage classification

There are several ways of classifying or prioritizing rack damage. Here are three examples:

   
BY PRIORITY LEVEL
BY SEVERITY
BY COLOR
   Level 1
Low Minor
Green
   Level 2
Medium Moderate
Yellow
   Level 3
High Severe
Red

When Damotech's surveyors assess damaged racks, they use the following to prioritize what they've found:

Unload: Severe damage requiring immediate unloading of the rack (bay)
High priority: Address this damage as soon as possible
Medium priority: Address promptly (6 to 12 months)
Low priority: Report and watch during subsequent inspections

Emphasis should be placed on inspecting racks regularly and reporting all damage.

The method you choose to label them is up to you as long as the damage is being addressed. If you are trying to promote safety within your warehouse, and have been emphasizing incident reporting, make Warning_Labelsure to respond quickly when damage is reported. Cordon off the affected area, unload if necessary, investigate the incident, and repair or replace the damaged component.

Any location deemed a high priority should be locked out to ensure that the rack is no longer supporting loads and to avoid the potential for collapse. A label or tape can be placed on the front of each damaged upright with a date. Extra caution should be used when placing or removing pallets near these locations.

Examples of pallet rack damage and issues found during an inspection

Damaged Brace on plalet rack

 

Damage to horizontal & diagonal rack braces

  • Missing brace
  • Detached from upright
  • Severely dented or deformed
Damage Baseplate on pallet rack

 

Damage to upright base plates

  • Missing or damaged base plate
Damage Out of plumb on pallet rack

 

Out-of-plumb / Out-of-straight

  • Maximum allowable out-of-plumb is 1/2” per 10 feet for loaded situations.
damage welded repair on pallet rack upright

 

Welded rack repairs

  • Welded splices and non-matching extensions
  • Unless approved by an engineer, any homemade repair should be replaced by an engineered repair solution or an undamaged equivalent rack component.
damaged beams on pallet rack

 

Damaged rack beam connectors

  • Detached beam clips
  • Missing safety pins
  • Severe dent in a beam
Damage pallet rack upright

 

Rack column damage from impacts by forklifts blades or outriggers

  • Dents, cracks, deviations
Damage no anchor pallet rack

 

Missing or damaged rack anchors

  • Missing anchors
  • Damaged or sheared anchors
Damage Shims on pallet rack

 

Rack column shims

  • Shims exceeding six or more times the diameter of the base
  • Shims dislodged from their original position.
  • Leveling pads are not well seated.
  • Should be secured with anchors
Damage Twisted Column on pallet rack

 

Damaged or twisted rack columns

  • Twisted rack column

Other considerations regarding rack damage prioritization and classification

Some damage may not look “critical.” However, it can still lead to extraordinary consequences, especially if left unaddressed for a long time or if damage accumulates in the same upright location. These sorts of issues can seem small and sometimes hard to see, but they still need to be tended to. Additionally, a combination of several “low priority” damages on a rack system can lead to a high priority. If an issue on your pallet rack has been identified, appropriate action should be taken to remediate it.

Finally, whichever classification system you choose to prioritize rack damage, do make sure that it is documented, labeled, and tended to in a reasonable amount of time.
