This document gives details of various fire retardant treatments available, the recommended specification and guidance for care and storage. This guidance is available for pdf download only.

Scaffold tube storage racks are a common feature of every scaffolding contractor’s yard and many long-term live sites.

This guidance note considers the design, use and maintenance of scaffold tube storage racks. 6 pages
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
