PRRS Training: What Every Warehouse Manager Needs to Know

The Person Responsible for Racking Safety — PRRS, sometimes called a Rack Safety Officer or RSO — is the named individual on site who owns the day-to-day safety of the racking. BS EN 15635 asks the operator of a storage installation to appoint someone with that responsibility, and HSE guidance HSG76 describes the same arrangement: regular visual inspection by trained site staff, with a periodic expert inspection on top.

The role exists because racking damage happens continuously and expert inspections happen periodically. If your only inspection is the annual one, then a frame struck in February carries load for ten months before anyone with a straight edge looks at it. The PRRS closes that window down to a week.

It is a nominated role, not an informal one. Nomination means someone specific has been told the job is theirs, has been trained to do it, has time allocated to do it, and has the authority to stop a bay being used. A site where 'everyone keeps an eye on the racking' has, in practice, nobody responsible for it — and that is exactly the gap that shows up in an investigation.

The core duty is a systematic visual inspection of the installation, normally weekly, following a fixed route so that no run is skipped and each area is covered at a predictable interval. The PRRS looks at uprights front and rear, beams and their end connectors, safety clips, bracing, baseplates and floor fixings, and the general condition of frame protection and barriers.

Findings are classified using the red, amber and green system from BS EN 15635 and recorded against a bay or run reference. Green items are logged and monitored. Amber items are escalated for planned repair. Red items are acted on immediately: offload the bay, isolate it, and keep it out of service. The classification is explained in more depth in red, amber and green racking damage explained.

Beyond the walk-round, the PRRS is the person who receives impact reports from MHE drivers and triggers the after-impact procedure; who keeps the written inspection record; who checks that load notices still match the configuration; and who acts as the site contact for the annual expert inspection, handing over the interim records so the inspector can see what has been happening between visits.

The role also has a cultural side that is easy to underestimate. The PRRS is the person drivers report near-misses to. If reporting an impact feels like an admission of fault, impacts stop being reported and the whole regime becomes fiction. A good PRRS makes reporting routine and blame-free.

Training starts with the legal framework, because a PRRS who does not know why they are doing the inspection tends to do it superficially. That means PUWER 1998 — regulation 5 on maintenance, regulation 6 on inspection, regulation 8 on information and instructions, regulation 9 on training — along with the general duty under the Health and Safety at Work etc. Act 1974, and the role of HSG76, BS EN 15635 and SEMA codes of practice.

It then moves to damage recognition, which is the practical heart of the course. Delegates learn what the common failure modes look like: bowed and kinked uprights, front and rear-face impact damage, twisted or torn connector holes, sheared bolts, permanently deflected beams, pulled or distorted end connectors, missing safety clips, removed bracing, loose and missing floor anchors, cracked slab around fixings, and corrosion as section loss rather than surface rust.

Next comes classification: how to measure out-of-straightness, why a sharp kink is worse than a smooth bow of the same size, how the green, amber and red tolerances are applied, and where the boundaries of the PRRS's judgement lie — the point at which a finding stops being a site decision and becomes something for an expert inspector.

Then load and configuration: how to read a load notice, what unit load and bay load mean, why beam pitch changes capacity, why components from different systems are not interchangeable, and how reconfiguration invalidates existing signage. If notices on site are missing or out of date, load notices and racking signage covers putting that right.

Finally, record-keeping and escalation: what a defensible weekly record looks like, how to reference locations consistently, how to photograph damage usefully, how to escalate amber and red items with an owner and a date, and how to close findings out in writing. Training normally runs as a half-day on site, working on the delegate's own racking, and ends with certification. Full detail is on our weekly PRRS training page and in the PRRS training guide.

The best PRRS is usually a warehouse supervisor, shift manager, team leader or health and safety coordinator — someone who is on the warehouse floor regularly, knows the layout, is present when impacts happen, and has enough standing to take a bay out of service without asking permission.

Authority matters more than seniority. If the PRRS finds a red-risk frame in the middle of a busy despatch shift, they need to be able to stop that bay being used immediately. If that decision has to be escalated to someone who is not on site, the regime will fail at exactly the moment it matters.

Cover matters too. Holidays, sickness and shift patterns mean a single PRRS is a single point of failure, and on multi-shift sites there is a strong case for training one per shift. Night-shift coverage in particular is worth thinking about: impacts often cluster on quieter shifts with less supervision, and they are the impacts least likely to be reported.

Training is not permanent. Refresher training keeps recognition sharp and captures changes to the installation, and any significant reconfiguration, new racking type or change of MHE fleet is a reason to revisit it.

The most common failure is the tick-sheet with no findings. Weeks of 'all clear' entries on a site with visible damage tells an inspector that the walk-round is being signed rather than done.

The second is inconsistent location referencing. If the same frame is described as 'aisle 3 near the shrink wrapper' one week and 'bay 27' the next, nobody can tell whether damage is progressing. Bay references need to be physically marked on the racking so that everyone uses the same language — including MHE drivers reporting an impact.

The third is unclosed escalations. Amber items with no completion date, red bays that quietly get reloaded, findings that appear on three consecutive reports. Each of those converts a good record into evidence of a known and unaddressed defect.

The fourth is under-reporting of impacts, which is structural rather than individual. Drivers report less when reporting is punished, when it is slow, or when nobody appears to act on it. Sites that add continuous racking impact monitoring usually find recorded impacts far exceed reported impacts, particularly outside day shift.

The two are complementary and neither substitutes for the other. The PRRS provides frequency and local knowledge; the expert inspection provides independence, measurement discipline and an assessment of the installation as a system — configuration, load notices, protection, and whether the weekly regime is functioning.

In practice, the interim records are what make the annual inspection efficient. An inspector arriving to a site with clean weekly records and marked bay references can focus on assessment rather than archaeology, and the resulting report is more useful because it shows trends rather than a single snapshot. Details of the expert inspection are on the annual SEMA-aligned inspection page.

Get the combination right and the outcome is straightforward: damage is found within days rather than months, red items never carry load, amber items are closed on schedule, and you hold a continuous written record that demonstrates the racking is being maintained and inspected — which is what PUWER regulation 6 asks for.
