Defective Throw Line

During a recent rescue drill, a defective throw line was discovered with a very low breaking strain.  Riber Products Limited (RIBER) who supplied it have identified a batch of 208 throw bags which could be at risk.

To ensure that throw bag rescue lines are fit for purpose they should be opened and checked. In particular:

  • The entire length of the rescue line should be examined for joins or other discontinuities. This can best be done by feeling along the length of the line with bare hands to identify rough patches or lumps.
  • Any knots, splices or other methods of securing the ends of the line to handles, quoits or other parts of the equipment should also be checked for integrity.
  • The throw bag should be inspected and tried at regular intervals and repacked according to the manufacturer’s instructions, as otherwise the line may not deploy freely from the bag when required.

Any throw bag rescue lines found to have joins or discontinuities should be removed from service and the original manufacturer /supplier informed.
