Traditionally, flame retardant timber decking has long been a fundamental requirement for scaffolding in various sectors of the industry. However, in the light of the ‘Grenfell’ disaster, there has been a substantial increase in the number of contracts which specify the need for flame retardant scaffold boards.
This document gives details of various fire retardant treatments available, the recommended specification and guidance for care and storage.

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.
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
This guidance explains the differences between ‘supplementary’ and ‘check’ couplers and gives typical design applications where high coupler forces could be expected and where additional loadbearing capacity to connections may be required. It also contains guidance on coupler configurations and expected safe working loads (SWLs) where supplementary couplers are used. To ensure that SWL values are as accurate as possible, data provided within this document is based on practical testing rather than calculation. 2 pages
In an ideal world all working platforms should contain no gaps or holes. This updated guidance is a simplification of the previous 2003 issue regarding working platforms, which have additional requirements over those that are normally provided on an access scaffold. Quality and the thickness of ply used are integral. 4 pages
