What are SEMA and HSE Guidelines for Pallet Racking Safety

Warehouse operations in the UK are required to abide by safe storage practices in order to minimise the risk to operators and maintain a safe working environment. These practices are primarily shaped by the Health and Safety Executive (HSE) and supported by the Storage Equipment Manufacturers Association (SEMA). Together, these two organisations have developed a framework that helps businesses comply with legislation and safely deploy pallet racking storage solutions.

Why SEMA best practice is encouraged by HSE

SEMA is an independent trade association, offering impartial advice to businesses to support them in complying with health and safety legislation and maintaining safe working practices. The organisation's designs, inspection regimes and maintenance recommendations are widely recognised as industry best practice and all warehousing businesses are strongly urged to adhere to SEMA racking design principles.

Businesses whose pallet racking design aligns with SEMA best practice are better able to demonstrate compliance with legislation including the Health and Safety at Work Act 1974, the Management of Health and Safety at Work Regulations 1999, the Workplace (Health, Safety and Welfare) Regulations 1992, Manual Handling Operations Regulations 1992, Lifting Operations and Lifting Equipment Regulations 1998, the Provision and Use of Work Equipment Regulations 1998 and the Work at Height Regulations 2005.

How HSE assesses pallet racking compliance

Should HSE be tasked with investigating a health and safety breach at a warehouse, they will check that the business is compliant with the legislation detailed above. They will also assess whether the operation has followed HSE guidance set out in HSG76 Warehousing and Storage, which covers safe storage systems, correct equipment uses, and preventative maintenance. This guidance also addresses working at height, vehicle movements, and manual and mechanical handling to help reduce workplace accidents.

Selecting appropriate warehouse racking

Matching racking systems to product characteristics

When developing a pallet racking design for a new warehouse, it is important to consider the physical qualities of the products being handled, as this will strongly influence the final design. For example, boxed or palletised goods are well suited to stacking systems, while horizontal racking is better suited to long or awkwardly shaped items.

Pallet condition and load stability

Should the decision be made to implement pallet racking, careful consideration must be given to pallet compatibility with the chosen solution, as uneven loading or damaged pallets can increase the likelihood of collapse or injury. HSE guidance is clear in this area, detailing common pallet-related hazards and recommending actions to address these hazards, for example, regular inspection of pallets and the immediate withdrawal of any with damage that could affect their structural integrity.

Further, HSE guidance details suitable securing methods, such as pallet wrapping, which stabilises the load and can again reduce the risk of accidents and injuries.

Installation standards and load notices

In terms of racking systems, SEMA takes the lead, recommending that all racking solutions must be mechanically sound, installed by competent persons and maintained in accordance with the manufacturer's stated regime. Every installation must have a load notice displayed which details its maximum load and beam capacity, and these limits must never be breached or the racking altered without the specific approval of the supplier or a qualified engineer.

Important safety considerations in pallet racking design

The greatest risk to warehouse operators from pallet racking is instability, causing loads to collapse and fall and threatening the safety of anybody working within the fall zone. For this reason, pallet racking design focuses on stability, with factors such as height-to-depth ratios, floor fixings and vehicle impact risk all influencing the structural integrity of the storage solution.

Where vehicle impacts are deemed likely, warehouse operators should invest in upright protection while securely fixing racking solutions to the floor. They should also consider widening aisles to reduce the risk of accidental damage and using high-visibility components to highlight risk areas.

SEMA and HSE recommend that the racking manufacturers maintenance guidelines are followed stringently as preventative maintenance is key to the long-term safety and efficacy of racking systems. Visual checks can be conducted daily by in-house personnel while annual inspections by an independent auditor can verify the safety of the solution as well as the inspection capabilities of the in-house personnel.

Maintaining long-term pallet racking safety

Pallet racking safety relies on warehouse operations adhering to legal requirements, following industry best practice and proactively engaging in routine maintenance. By following HSE guidance and SEMA best practice for storage solution design, installation and maintenance, the risk of accidents is reduced, protecting the workforce and ensuring resilience.
