If your facility runs steel storage racks anywhere in Canada, the rulebook quietly changed in 2024. CSA Group released <strong>CSA A344:24, User guide for steel storage racks</strong>, replacing the 2017 edition and absorbing the older A344.1 from 2005. The update is more than a cosmetic refresh. It pulls automated storage and retrieval systems into scope for the first time, swaps out a key structural reference, and tightens the language around what facility owners are expected to specify, purchase, and document.
For operations leaders, EHS managers, and facility directors, that has practical consequences. CSA standards are referenced in provincial occupational health and safety regulations across Canada, which means "the standard changed" usually translates to "your inspection program, your specs for the next rack purchase, and your documentation just got an audit-relevant update."
This guide walks through what CSA A344:24 covers, what changed from the 2017 edition, who is responsible for each piece, and the practical steps to bring your facility into alignment in the next 90 days.
What is CSA A344?
CSA A344 is the Canadian standard that gives owners and users of steel storage racks the framework to specify, install, inspect, and maintain them safely. It is the user-facing companion to <strong>CSA S345</strong>, which is the structural design standard engineers follow when designing the racks themselves.
Think of it this way. CSA S345 governs the people who design and build pallet racks. CSA A344 governs everyone else who lives with them — the buyer writing the spec, the receiving team accepting the install, the operations group running it daily, and the inspector signing it off annually.
The standard is widely adopted because most provincial OHS authorities either reference it directly or treat it as the recognized good-practice benchmark when evaluating whether an employer met their general duty to maintain a safe workplace. In Ontario, for example, the Ministry of Labour expects employers to follow recognized engineering standards for <a href="/services/storage-racking" class="text-primary underline hover:no-underline">racking systems</a>, and CSA A344 is the one inspectors point to.
What changed in CSA A344:24 versus the 2017 edition
CSA Group's published change log lists seven substantive updates. In plain language:
<strong>1. Automated storage and retrieval systems are now in scope.</strong> The previous edition treated AS/RS as a special case sitting outside the user guide. The 2024 edition explicitly brings AS/RS into the scope and special-applications clauses. If your facility operates a unit-load AS/RS, mini-load, vertical lift module, or shuttle system, the user-side responsibilities in A344 now apply to you in a way they did not before.
<strong>2. The structural reference moved from CSA S16 Annex N to CSA S345.</strong> This affects the engineers your supplier uses, but it matters to you because your purchase specs and your engineer-of-record letters should now cite CSA S345, not the old S16 Annex N reference.
<strong>3. The clause on specifying and purchasing pallet racks was expanded.</strong> This is the change with the biggest day-to-day impact for facility owners. The standard now goes deeper on the special considerations buyers should communicate to the supplier — things like seismic zone, environmental conditions (cold storage, washdown, corrosive), the actual unit-load weights and dimensions you will store, materials handling equipment turning radii, and the building structural conditions the rack will be anchored into. Vague POs lead to non-compliant installations; the new clause makes that risk explicit.
<strong>4. Documentation requirements for component capacities were updated.</strong> Suppliers are expected to provide clearer documentation of the load capacity of every component — beams, uprights, frames, accessories — so that the load plaques on the rack are traceable back to engineered values.
<strong>5. Each clause now has a title.</strong> A small editorial change with a real benefit: it makes the standard easier to reference in inspection reports, RFQs, and contracts.
<strong>6. Figures were updated.</strong> The diagrams now match modern rack styles and the current language of the standard.
<strong>7. References, definitions, and cross-references were modernized throughout.</strong>
The standard remains a "user guide" rather than a prescriptive design code. It is full of "shall" language where it counts, and the consensus among Canadian rack engineers and inspectors is that an inspector citing A344:24 will be treating those clauses as the compliance benchmark.
Who is responsible for what
A common mistake is to assume the rack supplier owns compliance. They do not. Responsibility under CSA A344 is shared:
<strong>The rack designer / supplier</strong> is responsible for designing and supplying racks that meet CSA S345 and providing the load capacity documentation, anchor specifications, and installation drawings.
<strong>The installer</strong> is responsible for installing the rack to the designer's drawings, including anchor placement, plumbness, and torqueing anchor bolts to specification.
<strong>The owner / employer</strong> is responsible for everything that happens after the install. That includes posting load capacity plaques, training operators, conducting routine inspections, commissioning expert inspections, repairing or replacing damaged components, and keeping documentation that proves all of the above happened.
If a rack collapses, the investigation will look at all three roles. But the owner is the only one who is on the hook for daily operational compliance, and the only one inspectors will ask to see records from on a normal site visit.
The inspection cadence CSA A344 expects

CSA A344 sets a layered inspection model that looks like this:
<strong>Daily — operator awareness.</strong> Anyone working in or around the racks should be trained to spot and report obvious damage. This is not a formal inspection; it is a cultural expectation that a forklift operator who hits an upright reports it before the end of shift.
<strong>Monthly — internal inspection.</strong> A trained employee — typically a lead hand, supervisor, or EHS coordinator — walks the racks on a documented checklist, looking for damage, missing components, overloads, missing or illegible plaques, and any change since the last walk. Records are kept.
<strong>Annual — expert inspection.</strong> A qualified third party — an engineering firm or certified rack inspector — conducts a full inspection of every rack in the facility, classifies any damage by severity (commonly using a green/amber/red traffic-light system), issues a written report with photos and locations, and provides repair or replacement recommendations. This is the inspection your insurer, your corporate EHS team, and a Ministry of Labour inspector will ask to see. MTLI runs <a href="/services/inspections" class="text-primary underline hover:no-underline">annual facility inspections</a> for facilities across Canada.
In Ontario specifically, monthly inspections are the regulatory expectation, and most Fortune-500 operators commission expert inspections annually. Some high-throughput operations — cold storage 24/7, e-commerce DCs with heavy MHE traffic — move to semi-annual expert inspections because the damage rate justifies it.
Load capacity plaques: small sign, big liability
CSA A344 has long required visible load capacity plaques on every rack. The 2024 edition reinforces the documentation chain that backs them up. The plaque must show the maximum unit-load weight per level and the maximum total bay weight, and those numbers must come from the rack designer's engineered calculations — not from a shop-floor estimate.
In a Ministry of Labour or insurer audit, three things get checked first: are plaques present, are they legible, and can you produce the engineering documentation that supports the numbers on them? Missing or wrong plaques are one of the most common citations on Canadian warehouse audits, and they are also one of the easiest to fix.
If your plaques are faded, missing, or you cannot trace them back to engineered values, that should be the first item on your A344:24 compliance plan.
Anchoring: when the floor is part of the rack
The 2024 standard continues to require that all racks be anchored to the floor when the height-to-depth ratio exceeds 3:1, and that drive-in and drive-through racks be anchored at all times regardless of ratio. Anchor bolts must be sized to handle both vertical and horizontal loads, and seismic considerations apply across most of British Columbia, parts of Quebec along the St. Lawrence corridor, and isolated zones elsewhere.
Practical implication: if you inherited racks from a tenant who left, or you bought used <a href="/services/storage-racking" class="text-primary underline hover:no-underline">racking systems</a> and re-erected them in a new facility, the anchoring is one of the first things an expert inspection will check. Re-used racks anchored into different concrete with the wrong bolt spec is a depressingly common finding.
A 90-day compliance plan for CSA A344:24
You don't need to do everything at once. A practical roll-in looks like this:
<strong>Days 1–30: Audit your current state.</strong> Pull your most recent expert inspection report. Confirm that load capacity plaques are present and legible on every bay. Confirm you have the engineered capacity documentation from your rack supplier on file. Confirm your monthly internal inspection program is actually running and producing records.
<strong>Days 31–60: Update your specifications.</strong> Any rack purchase order, RFQ, or capital project specification issued from now on should reference CSA A344:24 (not :17) and CSA S345 (not S16 Annex N). Update your standard purchase template, and brief your procurement and engineering teams.
<strong>Days 61–90: Commission an expert inspection</strong> if you haven't had one in the last 12 months. This is the single highest-leverage compliance action. The report becomes your baseline, your insurer-friendly document, and the evidence you needed if anything goes sideways before next year's inspection. You can <a href="/quote" class="text-primary underline hover:no-underline">request a free racking audit</a> from MTLI to kick this step off.
If you operate AS/RS, add a parallel review specific to those systems. The newly in-scope AS/RS clauses mean the next time an insurer or auditor asks how A344 applies to your automated storage, you need an answer.
Where this fits in your broader EHS program
CSA A344:24 sits alongside other recognized standards your facility already navigates — CSA Z432 for machine guarding, the provincial OHS regulations, your forklift operator training program, and your insurer's loss-control requirements. The good news: the operating cadence A344 expects (daily awareness, monthly internal, annual expert) maps cleanly onto an existing EHS calendar. The work is rarely about creating a new program. It is about tightening the program you already run, updating the references in your specs, and making sure the documentation actually exists when someone asks for it.
Frequently asked questions
Is CSA A344:24 mandatory in Canada?
CSA A344 is a voluntary national standard, but most provincial occupational health and safety authorities reference it as the recognized good-practice benchmark for steel storage rack safety. In a workplace incident investigation, an inspector or court will treat compliance with CSA A344 as evidence the employer met their general duty to maintain a safe workplace, and non-compliance as evidence they did not.
Do I need to redo my entire racking program because of CSA A344:24?
No. The 2024 edition is an evolution, not a rewrite. If your existing program already includes monthly internal inspections, <a href="/services/inspections" class="text-primary underline hover:no-underline">annual facility inspections</a>, visible capacity plaques, and engineered documentation from your supplier, you are most of the way there. The most common gap to close is updating your purchase specifications to reference the new edition and CSA S345, and confirming AS/RS systems are now covered in your inspection scope.
How often do I need a third-party expert rack inspection?
CSA A344 recommends an annual expert inspection at minimum. High-throughput operations with heavy materials handling traffic — e-commerce, cold storage, 24/7 distribution — often move to semi-annual. Your insurer or corporate EHS standard may require more frequent intervals.
Who can perform an expert rack inspection in Canada?
There is no single licensing body, but qualified inspectors typically come from engineering firms with structural rack experience, certified rack inspection companies, or an engineer of record retained by your facility. The inspector should produce a written report with photographed findings, a damage classification system, and repair or replacement recommendations.
What happens if a forklift hits a rack upright?
Tag the bay out of service, off-load it if safely possible, and have the damage assessed before reloading. CSA A344 expects damaged components to be evaluated by a qualified person, and either repaired to engineered specifications, replaced with original-equipment components, or engineer-approved for continued use. "Bend it back and keep going" is not a compliant repair.
Does CSA A344:24 apply to mezzanines and rack-supported buildings?
CSA A344 is specifically the user guide for steel storage racks. Mezzanines and rack-supported buildings are governed by additional standards including the National Building Code and CSA S136 / CSA S16 for the structural elements. A rack-supported building, by its nature, will reference both A344 and the building code structural standards in its design package.
