Guide for pallet racking inspection and repair companies · checked 30 October 2026
Pallet racking inspection and repair, recorded bay by bay, quoted defect by defect
A rack inspection is only worth what it pins down: which aisle, which bay, which level, which upright, how far out of straight, what colour, and who offloaded it. This guide covers ANSI MH16.1 and the US rules OSHA enforces through the General Duty Clause, the UK SEMA and HSG76 red/amber/green system, the 3/5/10 mm damage limits, LARC drawings and load plaques, high-piled storage permits and flue spaces, seismic anchoring, repair kits versus replacement, and how to run inspections and repairs for multi-site warehouse customers.

A 30-minute call. We show you pallet racking inspection and repair companies workflows running in Fieldproxy, built around how you work.
Short answer
Pallet racking inspection and repair companies use software that records every defect against an exact rack location (site, aisle, bay, level, component), with a photo, a measurement and a red, amber or green classification, then turns those defects into a repair quote and a re-inspection. Rack-specific tools include the Damotech Platform (North America) and the ROS Rack Inspection App on CHEQSITE (EN 15635 markets); many inspectors start on checklist apps such as SafetyCulture's template library, and installers that also run service crews use field service software such as ReachOut Suite. Fieldproxy is a configurable option built around the inspector's own rack register, damage rules, quote lines and per-DC reports.

How a job runs
One pallet racking inspection job, from first call to paid
The order the work really happens in, and what has to be written down at each step so nothing is argued about later.
- 1
Take the call and pull the rack record
Requests come in three kinds: the annual expert inspection, a post-impact call ('a reach truck hit aisle 12'), and a quote for a relocation or new install. Before booking, pull the site's rack make and profile, the LARC drawing and load plaque details, last year's open defects and the floor plan with aisle numbering. If there is no LARC drawing, say so in the quote: under MH16.1 the owner keeps it for the life of the rack.
- 2
Plan the walk around the DC's operation
Agree which aisles can be walked when, where pickers and reach trucks will be, whether high levels need a lift, and who on site can offload a bay if the inspector finds red damage. HSG76 expects normal inspections from ground level, with high-bay and automated systems covered by a rolling 20% sample each year so the whole installation is seen at least every five years.
- 3
Inspect location by location
Walk each aisle in order and record against an address: site, aisle, bay (between two frames), level (beam pair), and component (front or rear upright, horizontal or diagonal brace, beam, beam lock, base plate, anchor, column guard, deck, plaque). Check plumb with a level or laser against 1/240 of height, put a 1 m straight edge on any bent upright or brace, and look for missing beam locks, sheared anchors, splits and tears.
- 4
Classify and photograph every defect
Each defect gets a photo, the measured gap in mm, and a colour. Green is within limits: record and re-examine next time. Amber exceeds the limit: unload the affected positions and do not reload until repaired. Red is more than twice the limit: offload and isolate now, ideally in the inspector's presence, and rope or tag the bay off.
- 5
Hand over before leaving the building
Before the inspector leaves, the site's person responsible for racking safety (PRRS in UK guidance) signs that red locations are offloaded and isolated and amber locations are tagged with a dated label. The written report follows, but the red list cannot wait for it.
- 6
Quote the repair straight from the defects
Every amber and red defect becomes a quote line: replacement OEM upright frame, engineered repair kit, brace, beam pair, beam locks, anchors, base plate shims, column guards, a new load plaque. Repair kits and any non-OEM part need the kit maker's drawings and, under MH16.1 §4.4, a registered design professional confirming the repair restores at least the original design capacity.
- 7
Order parts and schedule the repair crew
Match the rack manufacturer and profile, or order the kit made to it. Book the crew around the DC: night shifts or weekend aisle closures, a forklift or lift on site, and confirmation that the bay is still offloaded when the crew arrives. Amber items have a clock: four weeks to repair or they become red.
- 8
Repair, re-inspect and release
After the repair, re-measure plumb and straightness, check beam locks and anchors, photograph from the same angle as the defect photo, and clear the isolation tag. Where the configuration changed (beam levels moved, bays removed), update the LARC drawing and the load plaque before the bay is reloaded.
- 9
Send the DC report and set the next visit
Report by DC: defects by colour and component, by aisle heat map, repairs done and open, and the trend since the last inspection. Invoice against the site's PO, and set the next expert inspection at no more than 12 months, sooner for aisles that keep getting hit.
What to record
The fields every pallet racking inspection job should capture
Site and rack register
- Customer, DC name and address, PRRS or rack safety contact, PO rules, shift pattern and aisle access windows
- Rack system per area: type (selective, drive-in, push-back, cantilever, carton flow), manufacturer and profile, installation date, installer
- Aisles with numbering as the DC uses it; bays per aisle; levels per bay with beam heights; frame height and depth
- LARC drawing reference and revision, load plaque text (unit and bay loads per level) and plaque photo
- Floor and anchoring: anchors per base plate, slab type (post-tensioned or not), seismic design category, special inspection record
- High-piled storage permit number, expiry, commodity class, sprinkler type (ceiling, in-rack, ESFR) and required flue spaces
Each defect
- Address: site / aisle / bay / level / component and side (front or rear, left or right)
- Defect type: bent upright, bent brace, torn or split section, beam deflection or damage, missing beam lock, sheared or missing anchor, base plate damage, out of plumb, overloaded, missing or wrong plaque, blocked flue space
- Measurement: gap under a 1 m straight edge in mm (pro rata on a shorter length), plumb reading against 1/240 of height
- Classification: green, amber or red; date classified; amber deadline (date + 4 weeks)
- Photo per defect with a scale or gauge in shot; second photo of the isolation tag
- Action taken on site: offloaded yes/no, by whom and when; isolation method (tag, rope, barrier)
Repairs and outputs
- Quote line per defect: part or kit, OEM or engineered repair, labour hours, lift or forklift, out-of-hours rate
- Repair kit drawing reference and the engineer's sign-off that capacity is restored
- Repair record: date, crew, parts fitted, before and after photos from the same position, re-measurement
- Isolation cleared by whom and when; LARC drawing and plaque updated yes/no
- Inspection report per DC, signed by the inspector, with SARI card number where the inspector holds one
Rules and standards
The rules that shape the work, with their sources
| Rule | What it means on the job |
|---|---|
| OSHA has no rack standard and cites the General Duty Clause | There is no specific pallet racking standard in 29 CFR 1910 Subpart N, so OSHA cites racking hazards under Section 5(a)(1). The most common cited conditions are bent or damaged columns and cross members, racks not anchored to the floor, missing load ratings, overloading, damaged parts replaced with non-equivalents, no inspection program and missing base plates. Abatement can cost far more than the penalty. source: Hodgson Russ, Is your pallet racking a latent OSHA violation and abatement nightmare? (27 Sep 2019) |
| Chewy, Ocala: under-ride citation affirmed | A reach truck operator was pinned and killed when his truck passed under a rack beam; the lowest beam in that aisle was 53 7/8 in from the floor. OSHA cited Chewy under the General Duty Clause for an under-ride hazard. The ALJ affirmed the citation and the $13,260 penalty on 22 Feb 2022, rejecting the argument that industry standards preempted the clause. source: OSHRC, Secretary of Labor v. Chewy, Inc., Docket 19-0868, ALJ Decision and Order (22 Feb 2022) |
| Walmart, Johnstown NY: secure storage citation upheld | A package fell from racks and struck a worker after a forklift in the next aisle hit the pallet. The Review Commission affirmed OSHA's secure storage citation and $10,684 proposed penalty on 9 Feb 2023, rejecting the argument that the racks were 'standard in the industry', and ordered the hazards fixed within six months. source: OSHA news release, Federal panel upholds citation against Walmart over hazardous shelving (24 Feb 2023) |
| OSHA maximum penalties | OSHA lists a maximum of $16,550 per serious violation and $165,514 per willful or repeated violation. A racking citation usually costs more in abatement (unloading, re-engineering, replacing frames) than in penalty. source: OSHA, Penalties (maximum per violation) |
| ANSI MH16.1-2023: owner duties and damaged racks (§4.1, §4.4) | The owner protects the rack's structural integrity, including inspecting for damage. Where visible damage could affect capacity, the affected portion is isolated and kept out of service until repaired or replaced, and a registered design professional confirms it is restored to at least its original design capacity before it returns to service. source: Damotech, RMI's ANSI MH16.1-2023 related excerpts and paraphrases |
| Load plaques and LARC drawings (§4.5-4.7) | A permanent plaque of at least 50 square inches shows maximum unit and distributed loads per level and bay loads, and stays accurate if the rack is altered. The owner keeps the Load Application and Rack Configuration drawings for the life of the rack and updates them when it is modified. Small installations (top level under 12 ft, footprint under 3,000 sq ft, no stacking on the top level) may be exempt from LARC drawings. source: Damotech, RMI's ANSI MH16.1-2023 related excerpts and paraphrases |
| Plumb, straightness, beam locks and anchors (§4.10, §9.4.3, §11) | Out-of-plumb and out-of-straight limits are both 1/240 of height. Beam connectors under machine loading need locks or bolts resisting 1,000 lbf (4,450 N) of upward force per connection. Each column needs a base plate and anchorage sized for the forces, with anchors designed to ACI 318 chapter 17; shims may not exceed six times the largest anchor bolt diameter. Straight-column frames over 6:1 height-to-depth must be anchored for uplift or braced. source: Damotech, RMI's ANSI MH16.1-2023 related excerpts and paraphrases |
| HSG76: PRRS, weekly checks and 12-month expert inspection | UK guidance has the site nominate a person responsible for racking safety (PRRS), with damage reported to them immediately, visual inspections weekly or at other risk-based intervals with a written record, and an expert inspection by a technically competent person at intervals of not more than 12 months. Automated and high-bay systems get at least 20% inspected each year on a rolling basis, the whole installation every five years. source: HSE, HSG76 Warehousing and storage: A guide to health and safety (2nd ed.), paras 634-653 and Table 11 |
| SEMA red, amber, green classification (HSG76 Table 11) | Green needs surveillance only and is recorded for re-examination. Amber is hazardous damage: once unloaded, not reloaded until repaired, isolated for example with dated labels, and redesignated red if not repaired within four weeks. Red is very serious damage: the area is offloaded immediately and isolated until repair, usually by replacing the component. SEMA stresses that green does not mean no risk. source: HSE, HSG76 Warehousing and storage: A guide to health and safety (2nd ed.), paras 634-653 and Table 11 |
| HSG76 floor fixing, beam locks and load notices | Fix all uprights next to aisles to the floor where the height-to-depth ratio is up to 6:1, all uprights between 6:1 and 10:1, and get the manufacturer's guidance above 10:1. Beam connector locks should always be fitted. Racking carries a clear notice of maximum loads and configurations, and moving the first or second beam level from the bottom always needs a capacity check. source: HSE, HSG76 Warehousing and storage: A guide to health and safety (2nd ed.), paras 634-653 and Table 11 |
| Damage limits over a 1 m straight edge | The ASI code of practice for AS 4084-2012: an upright bent in the direction of the frame bracing may not exceed a 3 mm gap, in the direction of the beam spans 5 mm, and bracing 10 mm in either plane; use a pro rata limit on shorter lengths (3 mm over 1000 mm = 2 mm over 600 mm). Damage over twice the limit is red. Tears and splits are unloaded and replaced immediately. EN 15635 uses the same idea: residual deformation measured over a 1 m reference length, red at more than twice the limit. source: Australian Steel Institute, Code of Practice: Rack Safety Inspections v2.1 (AS 4084-2012) |
| AS 4084 load plaque and anchors (Australia) | The installation carries a permanent, corrosion-resistant plaque at least 125 mm by 250 mm, mechanically fixed about 2 m above the floor. Selective pallet racking to AS 4084-2012 needs two anchors per base plate; installations before the 2012 standard may have one. source: Australian Steel Institute, Code of Practice: Rack Safety Inspections v2.1 (AS 4084-2012) |
| SARI: SEMA Approved Rack Inspector | SARIs are trained to carry out expert inspections to SEMA standards. The law asks for a competent person, not specifically a SARI, but since September 2025 customers can check an inspector's name and SARI ID card number on SEMA's free verification tool at sari.sema.org.uk. source: Builders Merchants News, SEMA launches racking inspector verification tool (25 Sep 2025) |
| High-piled combustible storage permits | In Seattle (2021 Seattle Fire Code chapter 32), high-piled storage is combustible stock over 12 ft high, or over 6 ft for high-hazard commodities such as tires, Group A plastics, lithium-ion batteries and idle pallets. A fire department permit is needed for a high-piled storage area over 500 sq ft, renewed annually, and a change in storage configuration can trigger the current code. source: Seattle Fire Department, Client Assistance Memo 5983, High-Piled Combustible Storage (Jan 2025) |
| Plans for a high-piled storage permit | IFC 3201.3 permit plans show storage areas, usable storage height, number of tiers in each rack, clearance from top of storage to sprinkler deflectors, aisle widths, commodity classes, fire department access doors, in-rack sprinkler valves and the dimensions and location of transverse and longitudinal flue spaces. Madison will not issue the license until plan review is approved. source: City of Madison Fire Department, High-Piled Combustible Storage Plan Review Requirements |
| Flue spaces must be maintained (IFC Table 3208.3) | For double-row racks with ceiling sprinklers over 25 ft, the table requires 3 in transverse flue spaces (vertically aligned) and 6 in longitudinal flue spaces; with ESFR sprinklers, 3 in transverse flues at least every 10 ft. Required flue spaces shall be maintained, and the fire official can require flue protection devices that may not be removed. source: 2015 Seattle Fire Code (IFC) Chapter 32, High-Piled Combustible Storage, incl. Table 3208.3 |
| Seismic design and building permits for racks | Bellevue WA applies IBC 2209 and ASCE 7-16 15.5.3: racks over 5 ft 9 in need a permit, freestanding racks over 8 ft and floor-and-wall-anchored racks over 10 ft need full engineering of the racks and anchorage, racks in buildings open to the public use an importance factor of 1.5, and post-installed anchors on racks 8 ft or taller get periodic special inspection. source: City of Bellevue, Steel Storage Racks interpretation IBC-2021-002 (ASCE 7-16 15.5.3) |
| California example: Poway | All rack storage over 8 ft needs a building permit before installation, with plans and calculations stamped by a California licensed structural engineer and a third-party special inspection report for the seismic anchoring. The fire department adds an annual permit where rack storage exceeds 500 sq ft and is 12 ft or higher. source: City of Poway Fire Prevention, Rack Storage policy (July 2021) |
| Engineered repair kits | Kits replace only the damaged lower section of an upright and bolt to the sound section above. Damotech says its column kits typically install in under an hour, often without unloading, are engineered to ANSI/RMI MH16.1, and may only be installed by its certified installers. Treat timing and unloading claims as the maker's, and keep the drawings with the repair record. source: Damotech, Pallet rack repair kits (DAMO PRO, FLEX, ADVANTAGE) |

Where it breaks
Where spreadsheets and generic software fall over
Defects are written as 'aisle 14, some damage' on a paper sheet. The repair crew arrives at night, cannot tell which of 40 uprights in the aisle was amber, and replaces the wrong frame.
Every defect is recorded against site / aisle / bay / level / component and side, with a photo, so the repair job opens on the exact location and the crew sees the defect photo before they lift a tool.
Amber damage sits in the report PDF. Nobody tracks the four weeks, the bay gets reloaded, and the next inspector finds it red with pallets on it.
Amber defects carry a deadline (classification date + 4 weeks). The office and the customer see it counting down, and it turns red automatically if no repair is booked and completed.
The inspection report and the repair quote are two documents built by two people. Lines get missed, the customer approves a total they cannot trace back to defects, and half the red items never get quoted.
The quote is generated from the defect list, one line per defect, priced from your parts and kit catalog, and the customer can approve line by line so red items can be approved now and greens deferred.
A 3PL with 12 DCs gets 12 different report formats from three inspection subcontractors and cannot answer 'how many red defects are open across the network?'
One rack register and one defect model across every DC, with a portal and a monthly roll-up by site, colour, component and aisle.
A repair moves a beam level or swaps an OEM frame for a repair kit, but the load plaque and LARC drawing are never updated, which is exactly what MH16.1 and an OSHA inspector look for.
Repair jobs that change configuration cannot close until the plaque photo and the LARC revision are attached, and a kit repair cannot close without the engineer's sign-off.
Generic field service apps think in 'one job, one asset'. A rack inspection is one job with 600 locations and 80 defects, and it has to work in a freezer aisle with no signal.
An inspection form that walks the rack register aisle by aisle offline, adds defects to locations in a few taps, and syncs photos when the inspector is back in coverage.
Checklist
The pallet racking inspection operations checklist
Print it, or hand it to whoever runs the office side.
- Rack register built per DC: aisles, bays, levels and components numbered the way the site numbers them
- LARC drawing and load plaque on file for each rack area, or a note that the owner has none
- Expert inspection booked no more than 12 months after the last one; high-bay sites on a 20% rolling sample
- Inspector carries a 1 m straight edge or damage gauge, level or laser for plumb, and a camera
- Plumb checked against 1/240 of height; bends measured in mm and logged with the direction
- Every defect photographed and classified green, amber or red on the spot
- Red locations offloaded and isolated before the inspector leaves, signed by the site's rack safety contact
- Amber locations tagged with a dated label and a repair deadline four weeks out
- Beam locks, anchors per base plate, base plates, column guards and plaques checked in every bay
- Flue spaces and clearance to sprinklers noted where the site holds a high-piled storage permit
- Repair quote built from the defect list, with OEM or engineered kit stated per line
- Kit repairs carry the maker's drawing and an engineer's capacity sign-off
- Re-inspection after repair, isolation cleared, plaque and LARC drawing updated if the configuration changed
- Report per DC sent with an aisle heat map and the trend since last inspection
Software options
What software pallet racking inspection and repair companies actually use
Judge each one on whether it fits the way your jobs run, not on the feature list. Bring a real job to every demo.
Damotech Platform
Warehouse operators and their repair partners in North America who want a rack-specific system
Cloud platform with iOS and Android apps: plan and elevation views of the warehouse, issues filtered by type, component and priority, photos attached to issues, load capacity by pallet position where calculated, and a multi-site dashboard. The app is free but needs a paid subscription priced by facilities and rack bays. Damotech also sells engineered repair kits and engineering services, so independent repair contractors should weigh that.
ROS Rack Inspection App (CHEQSITE)
Inspectors working to DIN EN 15635 in Europe
Inspections on a phone or tablet with rack data, replacement parts needed, defect photos, standard customer reports and management summaries, and before-and-after photos for repair technicians. Listed at €49.99 per user per month plus VAT.
Checklist apps (SafetyCulture / Mitti template library)
Small inspection outfits and in-house weekly checks
Community racking templates rate items green (continue use), amber (unload and replace within four weeks) or red (unload immediately) with photos as evidence. Good for the checklist; quoting, parts, repair crews and a per-location rack register sit elsewhere.
source: Checklist apps (SafetyCulture / Mitti template library)
ReachOut Suite
Material handling distributors and installers that also run service crews
General field service software. Advanced Storage & Retrieval Systems used it to replace manual technician scheduling and paper forms with a drag-and-drop scheduler, custom mobile forms and a CRM. Rack-level damage classification would be built in custom forms.
Questions to ask any vendor
- Can a defect be recorded against site, aisle, bay, level and component, using the customer's own aisle numbering?
- Does the app work offline in a freezer or a steel-roofed DC and keep photos tied to the right location when it syncs?
- Will an amber defect turn red automatically when its four weeks run out without a completed repair?
- Can the repair quote be generated from the defect list, one line per defect, and approved line by line by the customer?
- Can a repair job be blocked from closing until the engineer's sign-off, the new plaque photo and the LARC revision are attached?
- Can a 3PL see every DC's open red and amber defects in one portal, without us emailing PDFs?

Pallet racking inspection on Fieldproxy: built around how you already work
A Fieldproxy setup for a rack inspection and repair company is built around the rack register, not the customer: every DC is broken into aisles, bays, levels and components, and every defect lives on one of those addresses with its photo, measurement, colour and offload status. The inspector walks the register offline, the red list is signed off before leaving the building, and the quote, repair job, re-inspection and per-DC report are all built from the same defect records.
Module 1
Customer, DC and rack register
You cannot classify, quote or re-inspect a defect you cannot address. The register is the backbone of every other module.
- Records: Customer (3PL, retailer, manufacturer) → Site/DC → Rack area → Aisle → Bay → Level → Component; component types: upright (front/rear), horizontal brace, diagonal brace, beam, beam lock, base plate, anchor, column guard, deck, plaque
- Rack area fields: rack type (selective, drive-in, push-back, cantilever, carton flow), manufacturer and profile, frame height and depth, beam levels and heights, install date, installer
- Documents per rack area: LARC drawing with revision number, load plaque text and photo, original install drawings, repair kit drawings
- Compliance fields per site: high-piled storage permit number and expiry, commodity class, sprinkler type (ceiling, in-rack, ESFR), required flue spaces, seismic design category, special inspection record, anchors per base plate
- Bulk import from the DC's location master or the installer's layout so aisle and bay numbers match the warehouse system
Module 2
Inspection programme and recurring schedule
Expert inspections must not drift past 12 months, and post-impact calls must jump the queue.
- Service agreement per customer listing sites, inspection type and interval (e.g. annual expert, quarterly for high-impact DCs), rate card and PO rules
- Next expert inspection generated from the last completed one, never more than 12 months out
- High-bay or automated areas flagged for a rolling 20% sample, with which aisles were covered each year so every aisle is seen within five years
- Inspection types: Annual expert, Post-impact, Pre-relocation survey, Post-repair re-inspection, Permit support
- Inspection status: Due, Booked, Confirmed, In progress, Red handover pending, Report issued
Module 3
Inspector app: the location-by-location walk
An inspection is 600 locations and 80 defects, often in a freezer aisle with no signal. It has to be fast and exact.
- Opens on the site's aisle list; inspector picks an aisle and steps bay by bay; each bay shows last inspection's open defects at that location
- Add defect in a few taps: level, component, side, defect type (bent upright, bent brace, tear or split, beam damage, missing beam lock, sheared anchor, base plate, out of plumb, overload, missing plaque, blocked flue)
- Measurement fields: straight-edge gap in mm with direction (toward bracing / along beam span), measured length if under 1 m, plumb reading checked against 1/240 of height
- Photo per defect is mandatory; isolation tag photo is mandatory for amber and red
- Bay marked Inspected even when nothing is wrong, so coverage is provable
- Works offline and syncs on reconnect; voice notes per bay
Module 4
Damage classification and offload/isolate rules
The colour is the safety decision. It has to follow the rules, not the inspector's mood, and it has to outlive the visit.
- Classification computed from the measurement against the limits you choose (e.g. 3 / 5 / 10 mm, red at more than twice the limit) with inspector override and a required reason
- Red: status Offload required → Offloaded and isolated, with who offloaded it and when; the inspection cannot be closed until every red is Offloaded or the customer's refusal is signed
- Amber: deadline = classification date + 4 weeks; status Tagged, Repair booked, Repaired; auto-redesignated red at the deadline
- Green: stays on the location as Monitor and is shown to the next inspector in that bay
- Red handover sheet signed on the phone by the site's rack safety contact before the inspector leaves
Module 5
Repair quote from the inspection
The quote is the revenue, and it should be one click from the defect list, not a separate afternoon of typing.
- Quote lines generated per amber and red defect: replacement OEM frame, engineered repair kit (single column, front and back, brace), beam pair, beam locks, anchors, base plate and shims, column guard, new load plaque
- Each line carries the defect photo, location and colour so the customer sees exactly what they are paying for
- Labour priced by lines and access: out-of-hours rate, forklift or lift, aisle closure
- Customer approves line by line in the portal; red lines can be approved immediately and greens left as advisory
- Quote status: Draft, Sent, Partly approved, Approved, Declined (declined reds stay open and visible on every report)
Module 6
Parts, kits and engineering sign-off
A repair is only valid if the part matches the rack or the kit is engineered for it, and someone qualified says capacity is restored.
- Parts catalog by rack manufacturer and profile: frames by height and depth, beams by length and capacity, locks, anchors, guards; stock on hand and on order
- Kit orders linked to the defect with the maker's drawing reference
- Engineer sign-off record per repair (MH16.1 §4.4 registered design professional), required before a kit repair can close
- Purchase order to the rack manufacturer or kit maker raised from approved quote lines
Module 7
Repair crew scheduling around the DC
Repairs happen in someone else's live warehouse. Lost nights come from bays that were reloaded or aisles that were not closed.
- Repair job created from approved lines, grouped by aisle so one crew does one aisle closure
- Board shows amber deadlines so four-week items are scheduled first
- Pre-visit confirmation to the DC: bays still offloaded, aisle closed, forklift or lift available, shift contact
- Crew app opens on the defect photo and location; after-photo from the same angle, re-measurement, parts fitted
- Job status: Scheduled, Confirmed, In progress, Repaired, Re-inspected, Released
Module 8
Re-inspection, release and configuration changes
Under MH16.1 a repaired bay is not back in service until it is confirmed, and a changed rack needs a changed plaque.
- Post-repair re-inspection checklist: plumb, straightness, beam locks, anchors, guard refitted, isolation tag removed
- Release recorded with who released it and when; defect closed with before and after photos
- If beam levels moved or bays were removed: LARC revision and new plaque photo required before release
- Relocations and new installs run as projects: layout, permit drawings, anchoring and special inspection, plaques, handover inspection
Module 9
Reports per DC and the customer portal
The site's rack safety contact, the 3PL's regional safety lead and an OSHA or fire inspector all ask the same thing: show me this DC's racking.
- Inspection report PDF from your template: inspector name and SARI number where held, bays inspected, defects by colour with photos, red handover signature, quote reference
- Aisle heat map: defects per aisle and level, so the DC can see where trucks are hitting
- Portal per customer: site users see their DC, regional and head office users see all; open red and amber with deadlines; quotes to approve; LARC and plaque documents
- Dashboards: open reds by site, ambers past deadline, repeat-hit locations, quote approval rate, days from inspection to repair
Module 10
Invoicing and multi-site billing
3PLs pay per site and per PO. Inspection fees, repair work and parts need to land on the right one.
- Invoice on report issue (inspection) and on release (repair), each against the site PO
- Consolidated monthly invoice per customer where the contract asks for it
- Sync to QuickBooks or Xero; payment status back on the job
The AI agents, set up for pallet racking inspection and repair companies
| Agent | When | What it does | What you get |
|---|---|---|---|
| Watcher agent | An amber defect reaches its four-week deadline without a repair in Repaired status, or a red defect is still not marked Offloaded 24 hours after the inspection (e.g. threshold) | Checks the defect, any booked repair job and the quote status, and separates 'repair booked but late' from 'never approved' | Defect redesignated red with the reason logged, and an alert to your office and the site's rack safety contact listing the exact aisle, bay, level and component |
| Vision agent | An inspector photographs a load plaque, or a defect photo is saved with a damage gauge in shot | Reads the plaque's unit and bay loads into the rack area record, and on defect photos checks that a gauge or scale is visible and the component type matches what was selected | Plaque fields filled for review, and a 'retake photo' prompt on the phone when the defect photo cannot support the measurement |
| Voice agent | The inspector speaks while walking, for example 'aisle 14, bay 6, level 1, front upright, bent along the beam, 7 mm' | Parses location, component, direction and measurement and applies the site's damage limits | A defect record on the right location, pre-classified (in this example amber), waiting for the photo |
| Autopilot | A repair quote with red or amber lines sits in Sent for 3 days (e.g.), or an invoice passes its terms | Drafts a chase that lists the open red and amber locations with photos and the four-week deadline for each amber | A draft email to the site and regional contact that a person approves before it is sent |
| Document intelligence agent | A customer emails a LARC drawing, an installer layout or a 3PL work order PDF | Reads aisle and bay numbering, beam levels, rated loads, PO number and requested dates | Rack register entries or a post-impact inspection job created on the right site, ready for review |
| Scheduler agent | First Monday of each month | Rolls up every DC per customer: open reds and ambers, ambers near or past deadline, repairs completed, repeat-hit aisles, sites due for the annual expert inspection | A per-customer racking safety summary emailed to each 3PL's safety lead and to your operations manager |
Straight answers
Pallet racking inspection: FAQ
What software do pallet racking inspection and repair companies use?
They use software that records defects against exact rack locations with photos, measurements and a red, amber or green classification, then turns them into repair quotes and re-inspections. Rack-specific tools include the Damotech Platform and the ROS Rack Inspection App on CHEQSITE; smaller inspectors use checklist apps such as SafetyCulture's template library; installers that also run service crews use field service software such as ReachOut Suite. Fieldproxy is a configurable option built around a company's own rack register, damage rules and reports.
Does OSHA have a pallet rack standard?
No. OSHA cites racking hazards under the General Duty Clause, Section 5(a)(1), and sometimes the secure storage rule. Common citations are damaged columns, unanchored racks, missing load ratings, overloading and no inspection program. In Chewy's Ocala case the ALJ affirmed a $13,260 general duty penalty after a fatal under-ride accident.
How often should pallet racking be inspected?
UK guidance (HSE HSG76) calls for weekly visual checks by trained site staff and an expert inspection at intervals of not more than 12 months. The Australian code of practice for AS 4084 also says at least once every 12 months. ANSI MH16.1 makes inspection the owner's duty without fixing an interval, so most US contracts set annual expert inspections plus post-impact checks.
What do red, amber and green mean in a rack inspection?
Green is within limits: keep using it and re-check next time. Amber exceeds the limit: unload the affected positions, don't reload until repaired, and if it is not repaired within four weeks it becomes red. Red is more than twice the limit: offload and isolate immediately until the component is repaired or replaced.
How much can a pallet rack upright be bent before it must be repaired?
Using a 1 m straight edge, the AS 4084 practice (the same approach as SEMA and EN 15635) allows a 3 mm gap for an upright bent toward the frame bracing, 5 mm along the beam span, and 10 mm for bracing. ANSI MH16.1 sets out-of-straight and out-of-plumb limits of 1/240 of height. Tears and splits are replaced immediately.
What is a LARC drawing?
Load Application and Rack Configuration drawings show the rack layout, beam levels and permitted loads. Under ANSI MH16.1-2023 the owner keeps them for the life of the rack and updates them when the rack is modified; very small installations may be exempt.
Are load plaques required on pallet racking?
ANSI MH16.1-2023 calls for a permanent plaque of at least 50 square inches showing maximum unit and distributed loads per level and bay loads. HSG76 says racking should carry a clear notice of maximum loads and configurations, and AS 4084 requires a plaque of at least 125 × 250 mm about 2 m above the floor.
What is a SARI?
A SEMA Approved Rack Inspector, trained by the UK Storage Equipment Manufacturers' Association to carry out expert inspections. Using a SARI is not a legal requirement, but it is a recognised way to show competence, and SEMA's free tool at sari.sema.org.uk checks an inspector's name and SARI ID card number.
Can damaged racking be repaired instead of replaced?
Yes, with engineered repair kits that replace the damaged lower section of an upright and bolt to the sound section above. ANSI MH16.1 requires a registered design professional to confirm the repair restores at least the original design capacity before the rack goes back into service. Damaged parts are replaced, not straightened, and HSG76 says racking should never be altered (for example by welding) without consulting the manufacturer.
When do warehouse racks need a permit?
Two permits are common. A building permit for the rack structure and anchorage (Bellevue requires one above 5 ft 9 in and full engineering above 8 ft freestanding; Poway above 8 ft, with a stamped design and seismic anchoring special inspection). And a fire department high-piled storage permit, typically for storage areas over 500 sq ft with stock over 12 ft high (6 ft for high-hazard commodities), renewed annually.
What are flue spaces in rack storage?
Gaps between pallet loads that let sprinkler water and heat travel. Transverse flues run between loads across the rack; longitudinal flues run between back-to-back rows. The IFC table for double-row racks over 25 ft with ceiling sprinklers requires 3 in transverse and 6 in longitudinal flues, and required flue spaces must be maintained.
