Employers must provide appropriate levels of supervision taking into account the complexity of the work and the levels of training and competence of the scaffolders involved. All scaffolding must be erected, dismantled and altered in a safe manner.This can be achieved by following National Access and Scaffolding Confederation (NASC) Safety Guidance SG4 'Preventing falls in scaffolding operations' or by following similar guidance provided by the manufacturers of system scaffolding. Ideally, students are able to learn within this zone of proximal development, but this is often not the case. i7'V8}[=I~dT;7Q:fO'r@+,qYu:p{lvg6rt]4dsRJ!W bOz3/.m,P@`t;V/W9qp 7j Z*G+K{`S9fD=*V~{$?h}_6MT+|M|; 3n Occupational Safety and Health Administration, Outreach Training Program (10- and 30-hour Cards), OSHA Training Institute Education Centers, Severe Storm and Flood Recovery Assistance.
