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.
TG4:19 had amendments predominantly in relation to the orientation of ring bolts where current thinking is that settlement is probably greater than side wind loads so reduces potential shear loads on the bolt. Other minor changes were cosmetic. A recent update in April 2019 saw the removal of one reference only when the guidance was reissued as TG4:19. 24 pages
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
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. This guidance is available for pdf download only.
