Racking safety is the primary role of the Storage Equipment Manufacturers Association Limited.  We are committed to promoting and extending racking safety, installation and use of storage equipment manufactured and supplied by our members. 

About SEMA

Since the Storage Equipment Manufacturers' Association Limited was first launched in 1968.  SEMA has forged its reputation for excellence. Our member businesses, together with committees, SEMA racking regulations, and training combine their knowledge, and skill to become the leading voice on safe storage practice.

Today our provision promotes a cyclic approach to your racking system. This comprises; a safe design to meet SEMA’s rack regulations as supplied by member Manufacturers and SEMA Distributor Group (SDG) offering full traceability of the product.  Secondly, safe installation by SEMA Accredited Installation Companies (SAIC) using SEIRS qualified labour. And then, the installation will need to be maintained properly by SEMA-approved racking inspectors (SARI). This ensures your warehouse racking system is in safe and good working order.

British Materials Handling Federation

Racking Safety standards

Within the UK, quality assurance of your racking system comes when it has been designed to either the SEMA Code or EN 15512. Therefore it is acceptable to buy or sell storage equipment in the UK that has been designed to either of these codes.

SEMA is proactive in the development of standards for the storage industry in the UK. And we develop and influence both National and European Codes of Practice and guidelines for the design, supply, and installation of all types of storage equipment.

The SEMA Design Code has been in use for over 40 years and has a long history of providing racking with a high standard of safety. Our manufacturers are familiar with the SEMA Codes of Practice. Members ensure quality of design, manufacture, installation and finally usage. This includes inspection and repair. The design code is continually updated as part of a regular review process.  And SEMA manufacturers are committed to new revisions of the standard.
