National Access and Scaffolding Confederation issues warning

The NASC has published Health & Safety Alert – Defective Double Coupler which was issued jointly by major contractors Kier and Bam on 8 August 2018.

The alert explains that whilst erecting a handrail using tube and fitting, a drop forged double coupler failed when tightened. On initial inspection the coupler had sheared at the gate hinge pin lug.

Further inspections on random couplers identified that “a number of similar and additional defects were present”.
