Scaffolding shall be braced in the horizontal and vertical plane as well as in the lateral and longitudinal directions by use of diagonal stays or similar.
All couplers shall be locked when in use so that they cannot loosen accidentally.
Wooden material shall be unpainted and undamaged. Joints in posts, runners and braces shall be able to transmit the compressive and tensile forces for which the scaffolding is dimensioned.
Brackets mounted on wooden battens must not be used above 5 m. The battens shall be without joints and have a dimension of at least 95 mm x 95 mm. The battens shall be sufficiently braced to prevent them from breaking.
Trestle scaffolding shall not be taller than two metres.
