What are some common compliance requirements for cantilever warehouse racking?

Common compliance requirements for cantilever warehouse racking include competent design and installation, clearly displayed load information, suitable protection against vehicle impact, safe operating procedures, and planned inspections. The system must be used within its designed capacity and maintained in accordance with the manufacturer’s instructions, relevant British and European standards, and applicable health and safety legislation. Any damage, unauthorised alteration or unsafe condition should be recorded and dealt with promptly by suitably competent specialists.

There is no single piece of legislation covering every aspect of cantilever warehouse racking. Compliance normally involves applying the general duties under the Health and Safety at Work etc. Act, the Provision and Use of Work Equipment Regulations (PUWER) where applicable, and established guidance such as the HSE’s warehousing and storage recommendations. The design, use and maintenance of the system should also be considered against relevant standards, including BS EN 15629 for the specification of storage equipment and BS EN 15635 for its application and maintenance.

Competent design and specification

The cantilever system should be designed for the materials, dimensions, weights and handling methods used at the site. A competent designer should assess factors such as:

• the length, weight and rigidity of stored goods;
• the required arm spacing, column height and bay configuration;
• the intended loading pattern, including whether goods are stored on one or both sides;
• the reach, capacity and operating characteristics of handling equipment;
• the condition and load-bearing capacity of the supporting floor; and
• the required clearances, access routes and protection from impact.

Design assumptions should be documented and retained with the system records. A system should not be extended, relocated or reconfigured without checking that the revised arrangement remains suitable for the floor, loads and handling equipment.

Installation by suitably competent personnel

Installation should follow the approved design, the manufacturer’s instructions and the installer’s method statement. Columns, arms, braces, base plates, fixings and any restraints must be correctly positioned and secured. The floor should be checked before installation, particularly where anchors are being used or where the structure will be exposed to repeated impact or high loads.

Once installation is complete, the system should be checked before being put into service. This should include confirmation that the correct components have been used, connections are secure, the structure is plumb and stable, load notices are displayed, and access and escape routes remain clear. Installation records, drawings and handover information should be kept as part of the site’s equipment documentation.

Clearly displayed load information

Load notices should be positioned where operators can see them before loading the system. They should identify the safe working limits relevant to the installed arrangement, such as the maximum load per arm, level or bay where applicable, together with any restrictions on load distribution or storage configuration.

Operators should understand that capacity can change if arm levels, component types or loading arrangements are altered. A load notice must not be treated as permission to store goods that are longer, heavier or less stable than those covered by the design. If the information is missing, damaged or no longer accurate, the affected area should be taken out of use until it has been verified.

Safe loading and operating procedures

Written procedures should explain how materials are placed on and removed from the arms, how unstable or projecting loads are controlled, and which handling equipment is permitted. Loads should be positioned to avoid excessive point loading, overhang or uneven distribution. Goods should be supported in a way that prevents rolling, sliding or falling, using suitable restraints or supports where the design requires them.

Operators should be trained in the system’s capacity limits, the meaning of the load notices, safe loading techniques and the reporting process for damage. Training should also cover the risks created by vehicle movements, suspended loads, poor visibility and unauthorised adjustments. Only suitable handling equipment and attachments should be used, with enough clearance to prevent contact with columns and arms.

Protection from impact and falling materials

Where vehicles operate near the system, a risk assessment should determine whether column guards, barriers, bollards or other protective measures are required. Protection should be compatible with the design and should not create additional trip hazards or obstruct access. Traffic routes, pedestrian walkways and loading areas should be clearly managed and kept separate where reasonably practicable.

The storage arrangement should also address the risk of materials falling from the arms. The choice of arms, stops, restraints and handling methods should reflect the shape and behaviour of the goods being stored. Protection should never be improvised by drilling, welding or attaching unapproved components to the structure.

Planned inspections and defect control

The system should be subject to routine visual checks by trained employees and periodic inspections by a technically competent person. The inspection frequency should reflect the level of use, the operating environment, the type of handling equipment and the likelihood of impact. BS EN 15635 is commonly used as a framework for inspection and maintenance, with an expert inspection generally arranged at least annually, or more frequently where the risk assessment or inspection history indicates this is necessary.

Inspections should look for bent or cracked components, damaged welds, loose or missing fixings, displaced arms, distorted columns, damaged bracing, movement at the base, floor deterioration and missing load notices. Findings should be recorded with the location, severity and recommended action. If a defect presents an immediate risk, the affected area should be unloaded or isolated until it has been made safe.

Repairs, alterations and records

Damaged components should be repaired or replaced using parts approved for the system. Straightening, welding, drilling or other site modifications can affect the structural capacity and should not be carried out without a competent assessment and written approval. After a repair or alteration, the system should be rechecked before normal use resumes.

Useful compliance records include the original design information, installation and handover documents, load calculations, inspection reports, training records, maintenance and repair details, risk assessments, and evidence that defects have been closed out. Keeping these records together helps demonstrate that the system is being actively managed rather than inspected only after an incident.

Management responsibilities

Site management remains responsible for ensuring that the system is suitable, inspected, maintained and operated safely. This includes appointing people with appropriate knowledge and experience, communicating capacity limits, controlling access to unsafe areas, reviewing procedures after changes or incidents, and ensuring that contractors follow the site’s requirements.

In practice, the most reliable approach is to combine a suitable design with disciplined daily use, documented inspections and prompt specialist repairs. If there is uncertainty about capacity, damage, compatibility or a proposed alteration, stop using the affected section and obtain a competent technical assessment before it is returned to service.
