What is EN 15635 Pallet Racking Safety Standard
Warehouse pallet racks are the backbone of modern logistics. But because they constantly interact with heavy forklifts and massive loads, they can easily become a major safety hazard. A small dent from a forklift or a slightly overloaded beam might look minor, but over time, it can cause the entire rack system to collapse like a house of cards.
To prevent these disasters, Europe created a specific safety standard called EN 15635.
Unlike other regulations that focus on how racks are designed and built in a factory, EN 15635 is a daily user manual for warehouse managers. It tells you how to safely use, inspect, and maintain your racks after they are installed.

1. Why EN 15635 Matters in Plain English
Racks look tough, but they are under constant stress. In a busy warehouse, three big risks happen every day:
- Forklift Hits: A forklift bumps into a bottom post (upright), weakening its strength.
- Hidden Overloading: Beams bend because the cargo is too heavy or not centered properly.
- The Domino Effect: One damaged part gives out, causing a massive, chain-reaction collapse.
EN 15635 helps you spot these issues early so you can fix them before anyone gets hurt.
2. Who is in Charge? Meet the PRSES
EN 15635 states that safety cannot be a guessing game; someone needs to own it. The standard introduces a key role: the PRSES (Person Responsible for Safety of Storage Equipment).
Think of the PRSES as the warehouse's "Rack Captain." The responsibilities are shared clearly:
- The Warehouse Manager: Appoints the PRSES and ensures they have the time and budget to do the job.
- The PRSES (Rack Captain): Runs the weekly checks, keeps records, and schedules professional repairs.
- The Forklift Drivers: Report every single bump or scratch immediately, without fear of getting in trouble.
3. The "Traffic Light" System for Damage
How do you know if a dented rack is an emergency or just a scratch? EN 15635 makes it simple by using a color-coded system:
- Green (Safe): Low damage. The rack is safe to use. Just record it and check it again next time.
- Amber (Warning): The damage is getting worse. Do not put new loads on this rack. You have 4 weeks to fix it, or it automatically turns Red.
- Red (Danger): Severe damage. Stop using it immediately. Unload the rack, block off the aisle, and do not use it until it is fully repaired or replaced.
To catch these colors early, the standard requires a three-tier inspection routine: daily visual checks by drivers, weekly or monthly thorough checks by the PRSES, and an annual formal inspection by an independent outside expert.
4. Quick Comparison: European EN 15635 vs. U.S. OSHA
If your company operates globally, you have probably heard of OSHA (29 CFR 1910) in the United States. While both aim to keep workers safe, they work very differently.
Here is how they stack up:
| Feature | Europe: EN 15635 | United States: OSHA (29 CFR 1910) |
|---|---|---|
| What is it? | A technical best-practice guide specifically for rack safety. | A federal law covering all workplace safety. |
| The Focus | High focus on pallet racks (how to use, measure damage, and maintain them). | Broad focus on general safety (fire exits, electricity, chemicals). Racks are only a small part. |
| How it Guides You | Very specific. Gives you exact measurements for damage and the Green/Amber/Red system. | General. Tells you to keep a safe workplace, but does not give specific numbers for rack dents. |
| Enforcement | Required by insurance companies and for industry audits. | Enforced by government inspectors who can issue massive legal fines. |
| The Bottom Line | A practical maintenance blueprint for your racks. | The legal baseline to avoid fines and lawsuits. |
Pro-Tip: The best global warehouses use OSHA to stay legally compliant and use EN 15635 as their daily checklist to actually run a safer warehouse.
Four Common Mistakes to Avoid
Even with these rules, many warehouses still make simple mistakes that lead to accidents:
- Ignoring the "Little Dents": Thinking a small bend in a metal post isn't a big deal. It is. It weakens the rack's weight capacity significantly.
- Hiding Mistakes: Drivers hitting a rack and not reporting it because they are afraid of being blamed.
- No Weight Signs: Not displaying clear weight capacity signs on the racks, leading to accidental overloading.
- DIY Changes: Changing the height of the shelves without asking the manufacturer or a structural engineer first. This ruins the balance of the whole row.
Summary
EN 15635 isn't about paperwork or annoying rules; it is about building a daily habit. By appointing a specific person to watch the racks, using the simple green-yellow-red rule, and encouraging drivers to report accidents, you keep your team safe and your warehouse moving smoothly.
