When in use, scaffold boards are often subjected to harsh conditions and mistreatment and may deteriorate to such an extent that they become unsafe. To ensure that they remain in a safe and serviceable condition, they should be subjected to regular inspections/checks and where necessary repaired/refurbished to ensure that they remain fit for purpose. This document provides guidance on the inspection, care and maintenance of scaffold boards to maximise their operational service life.

BS2482:2009 defines both visual and machine strength grading standards for 38mm x 225mm boards supported at 1.2m spans and 63mm x 225mm boards supported at 2.5m spans; and machine strength grading standards only for 38mm x 225mm boards supported at 1.5m spans. This guidance is reviewed on the basis of removing A grade boards that should not exist. A visually graded board is still a BS2482 product and should be marked as such on the end band. 6 pages
The effects of heat on scaffolding equipment can have a significant and permanent effect on its strength and performance. This guidance explains the potential issues and the action to be taken if equipment has been subjected to a fire or similar conditions. This guidance is available for pdf download only.
Aluminium tubes, prefabricated beams and other components are widely used throughout the scaffolding industry. Whilst aluminium is not as stiff as steel and will deflect more when subjected to equivalent loads, it is much lighter and provides great advantages with regard to manual handling or the reduction weight. As aluminium couplers are not readily available, aluminium tube and beams are invariably connected with steel couplers and joint pins. Unfortunately, when two dissimilar metals such as aluminium and steel are in contact, a phenomenon known as ‘galvanic corrosion’ can occur where the corrosion of one of the metals, in this case aluminium, can be greatly accelerated. In severe cases this could seriously affect the integrity of the scaffold structure.

Please note - this guide is on back order as of 31 July 2024. We are waiting for a reprint and will send them out ASAP. The TG20 Operational Guide contains detailed practical guidance for most common types of scaffolding, supported by structural research and calculation. Guidance is provided for a range of standard structures which includes independent scaffolding, interior birdcages, chimney stack scaffolds, loading bays, ladder-access towers, free-standing towers, lift shaft towers, putlog scaffolding, exterior birdcages, tube and fitting mobile towers, tube and fitting loading bays without beams, and tied independent scaffolds with three inside boards. NASC members can purchase 10 or more copies of the TG20:21 Operational Guide book at the discounted rate of £25 per unit. To do so, please email sales@nasc.org.uk
