No, but several pieces of legislation and government guidance suggest they are a good idea. HSE’s guidance mentioned above recommends yearly SEMA approved racking inspections and regular racking inspections from competent staff.
Then there are the Provision and Use of Work Equipment Regulations 1998 (PUWER). These regulations outline the need for work equipment — which includes racking — to be inspected after installation or if the equipment is damaged in any way.
Finally, there is EN 15635. This European standard states that racking should be inspected by an expert at least once a year. This mirrors HSE’s advice on the topic. Though this European Standard doesn’t mention SEMA approved racking inspectors specifically, HSE does and so using SEMA approved racking inspectors for your expert inspections will be enough to comply with this European Standard.
