At a bare minimum, special or heavy duty scaffold should be used during demolition for containing dislodged materials or providing a safe platform for working and edge protection.
Factors that may affect the stability of a scaffold for demolition work include:
– Wind forces that act on containment sheeting on the face of the scaffold
– The load imposed by demolished material that’s dislodged onto the scaffold
– Progressive dismantling of the scaffold and removal of ties
– Water retention in the containment sheeting due to capillary action
– Progressive removal of building elements that affect the lateral stability of the scaffold’s upper portion
The risk control measures below should be implemented when you use scaffolds for demolition work:
– Scaffold planks need to be secured to avoid dislodgement from falling debris
– Regular inspection and maintenance of the scaffold
– Making sure that the scaffold is progressively dismantled and in line with demolition work
– You may need to reduce the vertical spacing of the scaffold ties to facilitate the demolition cycle.
– Containment sheeting on the scaffold’s internal face should be installed for the purpose of deflecting material into the building thus reducing the potential for scaffold overloading.
