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 gives details of the Fire Retardant treatments available for timber scaffold boards and battens.
Many free standing temporary scaffolding structures, such as access towers, major signboards and protection enclosures, need to be anchored to the ground, primarily to resist wind forces. This guidance gives some details of the various applications available.
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.
This guidance gives details of various products available which will satisfactorily hold down scaffold boards to prevent movement. Users should satisfy themselves that any proprietary system meets their requirements.
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.
