A safety alert has been issued by the Scaffolding Association following warnings being issued by a Kier BAM Joint Venture relating to defective double coupler scaffold fittings.
A Kier BAM safety alert had warned scaffolders when erecting a handrail using tube and fitting that a drop forged double coupler failed when tightened. The coupler was immediately replaced, quarantined and reported by a member of the kier BAM scaffold team. On initial inspection the coupler had sheared at the gate hinge pin lug.
The Drop Forged Double Couplers EN74-1 Class B were manufactured by Brisko in India and supplied by Altrad Beaver.
An investigation by Altrad has found that a human error occurred in the manufacturing process for a small batch. The batch has been identified and withdrawn. Corrective action has taken place and all remaining fittings have been inspected to ensure they are within manufacturing tolerances.
Altrad has said they are confident that this is a rare issue.
