BSI - BS5454 - Key Advice Tips

• Shelving should be installed allowing adequate ventilation and free movement of air around the stored materials.
• The lower shelf level should be at least 150mm from the ground.
• Shelving systems should have clear unobstructed apertures, ensuring that all shelf clips are concealed within the shelving structure and do not protrude through the frame to cause the snagging of valuable items.
• Shelf frames should not impede the clear aperture available for storage (where possible) to avoid snagging or damage. Ideally, a double-skinned frame should be used.
• Each shelf aperture should have a 50mm gap from the top of the stored material to the underside of the shelf above.
• Ideally, shelves should be manually adjustable to accommodate units of varying size and shape.
• The front edge of each shelf should be rounded or turned so that there is no sharp or angular edge to damage documents, injure people, or obstruct the withdrawal or replacement of documents.
• All shelves should have provision for labelling to clearly identify materials stored.
• Open frames are the preferred means of construction to ensure through flow of air.
• Solid side walls with perforations are suitable if loose items are to be stored.
• Solid back sheets to the shelving units should be avoided, although open-mesh back sheets or back-bracing is acceptable. Again, this ensures through flow of air.
• Lighting should be 300mm above the top of stored material, as exposure to light and heat can damage documents.

BS 5454 - Recommendations for mobile shelving

• For mobile shelving, there should be a minimum gap of 25mm between the mobile shelving runs, allowing (i) good air circulation; and (ii) fire suppression systems to effectively circulate gas in an emergency.
• When mobile bases close against one another, they should be designed in such a way as to ensure that all stock is contained within the shelving and not crushed by an adjacent mobile run.
• BS5454 states that methods of operation should predominately be mechanically or hand cranked systems to reduce any risk of fire associated with powered electric mobile systems.
• Push-lock handwheels should ideally be fitted to the operating end of the system to ensure personnel have the ability to lock off a run of shelving for access, without fear of harm from an adjacent mobile run closing the aisle.
• Ideally, anti-tip devices should be incorporated within the mobile base to prevent any possible tipping of a shelving unit. The unit is unlikely to fall flat, but it could cause damage to potentially valuable archives.
• Mobile shelving aisles should be no less than 750mm wide.
• Main gangways should be no less than 1100mm from the hand drive wheel to an adjacent wall or obstruction, providing adequate means of escape in the event of a fire.
