A scaffolding brick guard (20) comprises a panel (22) and at least two (hangers 28) for hanging the panel (22) vertically from a horizontal member of the scaffolding. Each hanger (28) has a first orientation in which it is substantially coplanar with the panel (22) and is attached to the panel (22) by means of a hinge whereby it is movable about an axis (32) into a second orientation not coplanar with the panel (22) to provide a hook to go over said horizontal member. When not in use a plurality of brick guards may be stacked by means of hollow conical stacking members (36) that nest together.
