Ask a warehouse crew whether pedestrians should cross a live aisle and every hand goes up with the right answer. Ask which crossing on this floor has a blind corner because the stack next to it went up two levels last month, and the room goes quiet.
That is the whole problem with warehouse safety training. It fails not because people do not know the rules in general, but because the rules that matter are specific: this aisle, this dock, this load. Generic training cannot carry that. What works is organising instruction around three risk clusters, each with its own legal basis, its own failure mode and its own delivery method.
What the accident figures point at
The Dutch Arbeidsinspectie Monitor arbeidsongevallen 2024, published on 2 October 2025, counted 1,990 reportable accidents, 2,001 victims and 58 fatalities. The cause breakdown is the useful part: falls 35 percent, contact with work equipment or an object 31 percent, struck by an object 17 percent, accident with a vehicle or mobile work equipment 8 percent.
In Belgium, Fedris recorded 97,591 accidents in the private sector in 2024 and 78 fatal accidents. Falls are the leading deviation, roughly one in five accidents and about a third of the most serious ones. For the transport and storage sector, the frequency rate is more than double the national average.
The picture is not exotic. People fall, people are struck, and people are caught by machines, on floors where machines and people share the space.
Cluster one: powered equipment and people on the same floor
The legal wording here is unusually direct. In Belgium, Codex art. IV.3-7, 1° states that self propelled mobile work equipment may only be driven by workers who have received adequate training for driving it safely, and 3° requires organisational measures to prevent workers on foot from entering the working zone. Book IV Title 2 adds the general layer: art. IV.2-3 reserves use of work equipment to those charged with it, IV.2-4 requires adequate specific training, IV.2-5 requires sufficient information and, where necessary, written instructions. In the Netherlands, Arbobesluit art. 7.17c lid 1 requires that self propelled mobile work equipment is operated by workers who possess specific expertise, art. 7.6 reserves use to those charged with it, and art. 7.11a requires the operating instructions to be brought to the worker's attention in a comprehensible form.
Now the honest part, which most training providers leave out. In neither country is a forklift certificate legally required, and there is no legal five year expiry on one. What the law requires is demonstrable competence. The certificate is the customary evidence of it, and a requirement from insurers and clients, which is a real obligation but a different kind of obligation from a legal one. That is not an argument against certificates. It is an argument for what has to sit next to them: proof that this driver knows this building.
One Belgian addition that gets missed: driving a forklift is a veiligheidsfunctie (safety function) under Codex art. I.4-1, paragraph 2, 1°, which means health surveillance applies, before assignment and periodically. Periodic, and note the word: periodic, not annual.
Traffic separation, and the numbers that are guidance
Keeping people and trucks apart is a layout decision first. Belgium regulates it in Codex Book III Title 1: art. III.1-20 sets the scope including traffic routes, loading bays and loading platforms, III.1-21 requires safe design, III.1-22 dimensioning for both people and goods traffic, III.1-23 vehicle routes at sufficient distance from doors, gates and pedestrian passages, and III.1-27 loading bays, dimensioned for the loads, with at least one exit and two where the length justifies it, and protection against falling or being trapped. In the Netherlands, Arbobesluit art. 3.14 covers connecting routes, alongside art. 3.6, 3.7 and 3.15, with the principle that pedestrians and internal transport are separated as far as possible.
Worth knowing: the corridor width figures circulating in Dutch guidance come from an Arbo-Informatieblad. They are guidance, not law.
The instruction that follows is site level, not theory level: which routes are live at which hours, which crossing is blind, where a walker is invisible to a reach truck driver.
Cluster two: dangerous goods in the hands of people who never drive
This cluster catches more people than most sites expect. ADR chapter 1.3 applies to anyone whose function relates to the transport of dangerous goods without driving the vehicle: loaders, packers, warehouse staff, the person who prints the label, the team leader deciding what goes on which pallet.
It has three components. 1.3.2.1 is general awareness, so the worker recognises what they are handling. 1.3.2.2 is function specific training, matched to what this person actually does. 1.3.2.3 is safety training on the hazards and on what to do when something goes wrong. Under 1.3.2.4 it is periodically supplemented to keep pace with regulatory change.
Two things to be precise about. First, ADR sets no refresher interval. There is no legal two year or five year cycle for 1.3 training, only a duty to keep it current with regulatory change, so treat any provider who sells a fixed interval as a legal requirement with care. Second, 1.3 training requires no exam and no state certificate. A company may deliver it in-house, using its own procedures. What it may not do is fail to prove it happened: 1.3.3 requires the employer to keep records of the training received and to make them available on request to the worker or the competent authority.
That combination, no exam but mandatory evidence, is why this cluster tends to be the weakest file in a warehouse. Nobody is sent anywhere, so nothing gets recorded.
Cluster three: the physical work, including the racking
The third cluster produces most of the injury statistics above, and has the loosest legal drafting.
Manual handling of loads is regulated in Belgium in Codex Boek VIII Titel 3, and in the Netherlands in Arbobesluit art. 5.2 to 5.6, with art. 5.5 on the information the worker must be given. Work at height sits in Codex Boek IV Titel 5 in Belgium and in Arbobesluit art. 3.16 and 7.23 onward in the Netherlands. Falls are the largest single cause category in both countries, so this is not a topic to leave on a slide.
Racking is the odd one out, because there is no dedicated legal article for it at all. In the Netherlands, racking is work equipment and therefore falls under Arbobesluit art. 7.4a, which requires periodic inspection by an expert person. The detail comes from NEN-EN 15635, which is a standard and not a law: an annual expert inspection, plus a weekly visual check by a designated and trained worker, recorded in a logbook.
Read that as a training requirement, not an inspection requirement. Somebody on your floor has to be designated, trained to recognise a bent upright or a damaged beam, and doing it weekly with a record. That person is usually on no training matrix.
An instruction model that survives three shifts
Four rules make the three clusters deliverable in a real building.
Make it site specific by default. Anything that would read the same in another company's warehouse is background, not instruction. The useful sentence names an aisle, a dock or a product.
Deliver it where the work is. A distribution centre runs two or three shifts and absorbs agency inflow at short notice. Anything that needs everyone in a room on Thursday reaches part of the crew and nobody on nights.
Make it comprehensible in the worker's own language. Arbobesluit art. 7.11a says comprehensible form. A Dutch instruction sheet given to a Romanian picker is paperwork.
Record participation per person. ADR 1.3.3 requires it outright. For the rest it is how you demonstrate competence when a client, an insurer or an inspector asks who was instructed on what, and when.
How this runs in Aristotl
Aristotl converts the documents you already maintain, the traffic plan, the dangerous goods handling instruction, the racking check procedure, the dock work instruction, into courses of three to five minutes that a warehouse worker completes on their own phone. No laptop, no app installation. Each course carries a knowledge check, so completion means something more than a tick, and content is translated per worker.
When the pick method changes or an aisle is rerouted, the new version reaches all three shifts at once. The dashboard shows completion per site, per role and per version, and records export, which is what you hand over when someone asks for your ADR 1.3 records or the instruction behind a driver's competence.
Bring one aisle to the demo
Pick the document that describes your busiest dock, your traffic plan or your dangerous goods procedure. In a demo we turn it into courses for your shifts, and show what the completion record for that crew looks like the next morning.
