Warehouse Racking Inspection Guide: Daily Checks, SEMA Inspections and Damage Limits

The Legal Framework for Racking Safety

Pallet racking and shelving systems are work equipment within the scope of the Provision and Use of Work Equipment Regulations 1998 (PUWER). PUWER requires that work equipment is maintained in an efficient state, in efficient working order, and in good repair. For racking, this means a structured inspection regime — not just responding to obvious damage when it occurs.

HSE guidance note HSG76 Warehousing and Storage: A Guide to Health and Safety sets out the practical requirements for racking management. The Storage Equipment Manufacturers' Association (SEMA) has published a Code of Practice for the Use of Static Racking that represents the industry standard and is referenced by the HSE. Compliance with the SEMA Code of Practice is the benchmark against which racking safety is assessed in the event of an inspection or incident.

Three Levels of Racking Inspection

Level 1: User Checks (Daily or Weekly)

The first level of inspection is carried out by trained warehouse operatives as part of their normal working routine. This does not require specialist racking knowledge — it requires that workers know what damage looks like and are empowered to report it. A brief walk-through at the start of each shift or each week should look for:

• Dents, bends, or deformation in upright frames
• Beams that appear to sag, are out of alignment, or have been displaced
• Missing or dislodged beam safety pins or clips
• Signs of overloading (damaged beams, tilting frames)
• Damage to floor fixings or baseplate deformation
• Spilled loads or incorrectly placed pallets that create unstable loading conditions

Any damage found should be reported immediately. Until inspected by a competent person, damaged racking should not be loaded.

Level 2: Responsible Person Inspection (Monthly or Quarterly)

The SEMA Code requires each racking installation to have a designated Responsible Person (RP) — someone with appropriate knowledge of racking safety who carries out more detailed periodic inspections, typically monthly or quarterly. The RP does not need to be a racking specialist, but should have completed SEMA awareness training or equivalent. Inspection records must be kept, noting the date, inspector, areas covered, any damage found, and the action taken.

Level 3: Expert Inspection (Annual Minimum)

A minimum of once per year, racking should be inspected by a SEMA-approved racking inspector (SARI) or equivalent independent expert. This inspection results in a written report categorising any damage found using the SEMA traffic light system and making recommendations for repair or load restriction. The annual expert inspection is a mandatory requirement of the SEMA Code of Practice and is the standard expected by the HSE.

SEMA Traffic Light Damage Classification

The SEMA damage classification system uses a simple traffic light colour code to categorise the severity of racking damage found during inspection:

• Green: The racking is safe for continued use. Any minor defects noted should be monitored and addressed in due course.
• Amber: Damage is present that requires attention. The affected area should have its load reduced or access restricted, and repair or replacement must be carried out within the timeframe specified in the inspection report.
• Red: The affected section must be immediately unloaded and taken out of use. It must not be reloaded until repairs have been completed and signed off. In serious cases, the entire bay or run may need to be cleared.

Red classifications require immediate action and should never be overridden on operational grounds. The risk of collapse is too significant.

Common Damage Types to Look For

The most frequently found types of racking damage in warehouses include:

• Upright deformation: A bend or dent in a vertical frame member, typically caused by forklift impact. Even apparently minor deformation can significantly reduce load capacity.
• Beam deflection: Beams that sag under load beyond the maximum permitted by the manufacturer. The SEMA Code allows a maximum mid-span deflection of span ÷ 200.
• Missing safety pins or beam locks: Beams can be displaced upwards by a forklift tine if safety pins are absent — a potentially catastrophic failure mode.
• Floor anchor damage: Damaged or missing floor bolts compromise the stability of the entire upright, particularly under lateral load.

Load Notices

Every racking installation must display a load notice clearly showing the maximum permissible unit load per beam level and the maximum bay load. This information is provided by the racking manufacturer at installation. If the notice is missing, damaged, or the installation has been altered since original commissioning, a racking inspection should be carried out and the load notice reissued before the racking is loaded again.

Never estimate or assume load capacities — the consequences of overloading racking are severe, and liability rests with the operator if loads exceed the rated capacity.

After a Forklift Impact

Any forklift impact with racking — however minor it may appear — must be reported and the affected section inspected by a competent person before loading resumes. Internal reporting cultures that discourage disclosure of minor impacts are a significant risk factor: damage that appears cosmetic can have compromised the structural capacity of a frame sufficiently to cause failure under normal operating loads. A clear, no-blame reporting procedure is one of the most important elements of a racking safety culture.

Installing warehouse safety barriers and upright protectors around vulnerable frame members is an effective first line of defence against impact damage in the first place.
