What safety standards should warehouse racking systems comply with in the UK?

Warehouse racking systems in the UK should be designed, manufactured, installed and maintained in accordance with the relevant BS EN standards, the manufacturer’s instructions and applicable health and safety law. The main standard for safe use and inspection is BS EN 15635: Steel static storage systems – Application and maintenance of storage equipment. This is supported by HSE guidance, particularly HSG76: Warehousing and storage, and by the requirements of the Provision and Use of Work Equipment Regulations 1998 (PUWER).

Compliance is not established simply by buying a system that carries a recognised standard. The complete installation must be suitable for its intended loads and layout, correctly assembled, protected against foreseeable damage and subject to documented inspection and maintenance. This remains important when purchasing used or budget warehouse racking, because age or price does not remove the duty to provide safe work equipment.

Key standards for warehouse racking

• BS EN 15635 sets out practical requirements for the safe use, inspection, maintenance and repair of steel static storage systems. It covers matters such as responsibilities, damage assessment, load information, reporting procedures and inspection arrangements.
• BS EN 15512 covers the structural design of adjustable pallet warehouse racking. It addresses the engineering principles used to assess the stability and load-bearing performance of the structure.
• BS EN 15629 covers the specification of storage equipment. It helps ensure that the system is specified with appropriate information about loads, operating conditions, building constraints and protection requirements.
• BS EN 15620 addresses tolerances, deformations and clearances for adjustable pallet warehouse racking. These requirements help ensure that the installation has suitable gaps and alignment for safe operation.

Other standards may apply depending on the type of storage system, materials, access equipment and operating environment. The correct standard should therefore be confirmed from the system design, manufacturer’s documentation and the conditions in the warehouse rather than assumed from the appearance of the equipment.

Requirements under PUWER

PUWER applies to work equipment used by employees, and warehouse racking can fall within its scope. In practical terms, the equipment must be suitable for the task and working environment, maintained in an efficient condition, inspected where deterioration could create a risk, and used by people who have received suitable information, instruction and training.

For warehouse racking, this means the operator should consider the intended pallet dimensions and weights, loading patterns, forklift movements, floor conditions, impact risks, lighting, access arrangements and any changes to the building or working process. A system that was suitable for one operation may no longer be suitable after a layout change, a change in load or the introduction of different handling equipment.

Design and installation controls

A competent supplier or designer should establish the required load capacity and specify the system for the actual site conditions. This includes checking the building floor, bay configuration, beam levels, frame height, aisle clearances, pallet overhang, stability requirements and the likely forces created during loading and unloading.

Installation should follow the approved design and the manufacturer’s instructions. Frames and beams should be correctly positioned, connected and secured, with suitable floor fixings where required. The system should be checked after installation for alignment, damage, missing components, correct bracing and adequate protection from vehicle impact. Any deviation from the original design should be assessed by a suitably competent person before the warehouse racking is put into use.

Where an installation forms part of construction or alteration work, duties under the Construction (Design and Management) Regulations may also be relevant. The exact legal responsibilities depend on the project, but they do not replace the need to manage the completed system under PUWER and BS EN 15635.

Load information and safe operation

Every operational installation should have clear, durable load notices in suitable positions. These should communicate the permitted working loads and any restrictions needed for safe use. The information should correspond with the actual configuration, including beam levels, bay arrangement and pallet type.

Operators should not exceed the stated loads, alter beam positions, remove structural components or add parts from another system without approval. Changes can affect the load capacity and stability of the entire installation. If the required load, pallet size or layout changes, the system should be reassessed and the load notices updated before use.

Safe working procedures should cover correct pallet placement, damaged pallets, uneven or unstable loads, forklift routes, pedestrian segregation and reporting of impacts. Staff should understand what damage looks like and know that damaged warehouse racking must be reported immediately rather than left for a later maintenance visit.

Inspection requirements under BS EN 15635

The employer or operator should appoint a Person Responsible for Storage Equipment Safety (PRRS), or an equivalent suitably responsible role, to coordinate the inspection and maintenance arrangements. The PRRS should understand the system, its operating risks and the actions required when defects are identified.

• Users should carry out routine visual checks during normal operations and report defects, impacts and unsafe conditions without delay.
• A formal visual inspection should be completed at appropriate intervals by a trained and competent person. The frequency should reflect the warehouse environment, traffic levels, previous damage and risk assessment.
• An expert inspection should be carried out at least every twelve months, or more frequently where the risk assessment, operating conditions or inspection findings require it.
• Inspection results should be recorded, including the location and nature of damage, the risk classification, the corrective action and the date of completion.

BS EN 15635 commonly distinguishes between serious damage requiring immediate action, damage requiring remedial work within a defined period and minor damage that should be monitored. The precise response depends on the type and severity of the defect. Where there is a serious risk of collapse, the affected area should be isolated and unloaded until it has been made safe.

Damage, repairs and alterations

Impact damage to frames, uprights, bracing, beams, connectors, guards or floor fixings should be assessed by a competent person. Straightening or welding damaged structural components on site is not an acceptable substitute for an approved repair method unless it has been specifically designed and authorised by a suitably qualified party.

Replacement components should be compatible with the original system and appropriate for the required loads. Mixing components from different manufacturers or product ranges can change the design assumptions and should not be done without technical confirmation. Repairs should be completed promptly, followed by a check that the affected bay and surrounding structure are safe to return to service.

Records should include inspection reports, repair evidence, installation information, load specifications, risk assessments, training records and details of any approved alterations. Good records provide evidence that defects are being managed and help identify recurring impact or operational problems.

How to check whether a system is compliant

1. Identify the manufacturer, system type, configuration and intended use.
2. Confirm that the design and load information match the current bay layout, pallets and operating conditions.
3. Check that the installation is correctly assembled, anchored where required and protected from foreseeable impact.
4. Verify that load notices are present, legible and accurate.
5. Review the inspection schedule and confirm that reports, corrective actions and repairs are documented.
6. Ensure operators have suitable instruction and that reporting arrangements are understood.
7. Arrange a competent assessment where documentation is missing, the system has been altered, or its condition and capacity are uncertain.

For used warehouse racking, the assessment should be particularly careful. Previous loading, dismantling, transport, impact and incorrect reassembly may not be visible from a basic visual check. Missing design information or load data should be treated as a safety concern, not as a reason to make an unsupported estimate of capacity.

In practice, UK compliance depends on combining the relevant BS EN standards with PUWER duties, HSE guidance, manufacturer requirements and a site-specific risk assessment. Regular inspections are essential, but they are only one part of the system. Safe design, competent installation, accurate load information, trained operators, controlled alterations and prompt repairs all need to work together to keep warehouse racking safe and efficient.
