What are the compliance requirements for narrow & high-bay longspan warehouse racking systems?

Compliance for narrow and high-bay longspan warehouse racking systems depends on suitable design, documented risk assessment, competent installation, clear load information, effective impact protection and planned inspections. The system must be safe for its intended loads and layout, maintained in a serviceable condition and operated by people who understand the relevant procedures.

UK compliance is based on a combination of health and safety legislation, recognised engineering standards and site-specific controls. No single certificate makes a warehouse racking system compliant. The supporting design information, inspection records, repair history, training arrangements and day-to-day controls all contribute to safe operation.

Relevant UK legislation and guidance

• The Health and Safety at Work etc. Act requires employers and others in control of workplaces to protect people from foreseeable risks.
• The Management of Health and Safety at Work Regulations require suitable and sufficient risk assessments, appropriate arrangements and competent support for managing risks.
• The Provision and Use of Work Equipment Regulations apply to work equipment and require it to be suitable, properly maintained and used by people who have received adequate information, instruction and training. Warehouse racking is generally treated as work equipment for these purposes.
• The Workplace (Health, Safety and Welfare) Regulations are relevant to the condition and layout of the workplace, including safe access, traffic routes, lighting and housekeeping.
• The Regulatory Reform (Fire Safety) Order applies to fire precautions and emergency arrangements where the premises fall within its scope. Storage layouts must not compromise escape routes, fire protection measures or access for emergency response.
• HSE guidance, including HSG76 Warehousing and storage, provides practical advice on storage equipment, workplace transport, inspections, load safety and operator controls.

These duties normally rest with the employer, building occupier or other responsible person, depending on the specific obligation. A competent warehouse racking specialist can provide technical support, but responsibility for managing workplace risks remains with the duty holder.

Use the correct design and specification

The system should be designed for the actual building, goods, handling equipment and operating methods. This includes the dimensions and weights of stored loads, beam and frame capacities, bay configuration, clearances, floor condition, available headroom, aisle widths and the effects of loading and unloading activities.

Relevant European standards may include BS EN 15629 for the specification of storage equipment, BS EN 15620 for installation tolerances and clearances, BS EN 15512 for the structural design of adjustable pallet racking and BS EN 15635 for the use and maintenance of storage equipment. The applicable standard depends on the type and design of the system. These standards are not a replacement for legislation, but they provide an important benchmark for competent design, installation, inspection and use.

Where the structure is unusual, heavily loaded, installed in a challenging building or altered from its original design, calculations and confirmation from a suitably qualified designer may be necessary. The supporting information should identify the design assumptions and any restrictions, rather than relying only on the appearance of the finished installation.

Confirm floor, building and environmental suitability

The supporting floor must be capable of carrying the imposed loads, including concentrated loads at frame baseplates. Its level, condition, strength and suitability for the proposed anchors should be checked before installation. The building should also be assessed for obstructions, roof structures, lighting, sprinklers, doors, fire detection equipment and other services that could affect the proposed height or arrangement.

High-bay layouts require particular attention to stability, vertical clearances, lifting equipment, visibility and access for inspection. Narrow aisles must be compatible with the trucks or other handling equipment being used. The operating method should allow loads to be placed and removed without striking frames, beams or stored goods.

Provide visible load information

Load notices should be displayed prominently and kept accurate. They should identify the permitted configuration and the relevant safe working loads, including the limits for individual beams, bays or other load-bearing components where applicable. Information should reflect the installed arrangement, not a previous layout or an assumed standard configuration.

Load notices must be reviewed whenever the system is altered. Changing beam levels, adding components, changing pallet sizes or increasing stored load weights can invalidate the original design information. Operators should be instructed not to exceed the stated limits or place damaged, unstable or unsuitable loads into storage.

Control installation and alterations

Installation should be completed by competent operatives using the approved layout and manufacturer or designer instructions. The finished system should be checked for correct component selection, anchoring, bracing, alignment, clearances and protection. Any deviation from the design should be recorded and assessed before the system is put into use.

Alterations should never be treated as minor simply because they involve moving a beam or replacing an individual component. A change can affect load capacity, stability and clearances. The proposed modification should be reviewed by a competent person, approved where necessary and reflected in the load notices and site records.

Following installation or significant alteration, retain the relevant design information, drawings, handover documents, inspection arrangements and maintenance instructions. This information helps future inspectors and repair teams understand the system’s intended configuration.

Protect the system from impact

Impact from forklift trucks, pallet trucks and other workplace vehicles is a common cause of damage. Risk controls should be selected according to the traffic routes, vehicle types, turning movements, visibility and frequency of handling operations. Suitable controls may include frame guards, end-of-aisle protection, barriers, clearly defined routes, separation of pedestrians and vehicles, improved lighting and changes to the operating procedure.

Protection must not obstruct access, create a new trip hazard or prevent proper inspection of the structure. It should be securely installed and included in routine checks. Damaged protection does not remove the underlying risk and should be repaired or replaced promptly.

Inspect in line with BS EN 15635

A nominated person responsible for storage equipment should coordinate the inspection and reporting process. Operators should be encouraged to report damage, instability, missing components, displaced loads and other concerns immediately. Regular visual checks should also be carried out at intervals based on the risk assessment, with a more detailed inspection by a technically competent person at intervals of no more than twelve months, unless a shorter interval is justified by the conditions of use.

Inspections should cover frames, uprights, bracing, beams, connectors, locking devices, baseplates, anchors, protection, load notices, clearances, alignment and signs of overloading or impact. The inspection should consider the surrounding workplace as well as the storage equipment, including traffic routes, housekeeping and access for emergency arrangements.

Findings should be recorded clearly, with the location, nature and severity of each defect. Where damage presents an immediate danger, the affected bay or area should be taken out of service, unloaded where safe to do so and clearly identified until a competent person confirms the appropriate action. Less serious defects should still be assigned to a responsible person and repaired within a defined timescale.

Repair defects using suitable components and methods

Repairs should be based on the inspection findings and the original design. Damaged structural components should not be straightened, welded, drilled or substituted without suitable technical approval. Replacement parts should be compatible with the installed system and capable of providing the required performance.

After repair, the affected area should be checked before being returned to service. Update the inspection and repair records, and revise the load information if the repair or component change affects the approved configuration. Temporary arrangements should be controlled and removed as soon as the permanent repair is completed.

Train operators and enforce safe procedures

People who load, unload, inspect or alter the system need information and instruction appropriate to their role. Training should cover safe loading methods, load stability, capacity limits, prohibited alterations, damage reporting, pedestrian and vehicle controls, emergency arrangements and the action to take when a defect is found.

Procedures should address the actual storage operation, including the handling equipment used in narrow aisles and at high levels. Supervisors should monitor compliance and challenge unsafe practices such as placing uneven loads, overhanging pallets, damaged pallets or unauthorised components into the system.

Keep compliance evidence up to date

Useful records include the risk assessment, design calculations or specifications, layout drawings, load notices, installation and handover documents, inspection reports, defect close-out records, repair information, training records and evidence of any approved alterations. Keep the records accessible to the people responsible for operating and maintaining the storage system.

Compliance should be reviewed when the layout, stored goods, handling equipment, building, staffing or operating process changes. A system that was suitable when installed may no longer be suitable after a change in load profile or working method. Regular review, prompt reporting and competent repairs provide the practical controls needed to keep narrow and high-bay longspan warehouse racking safe, efficient and legally defensible.
