Blastguard

UDB Protection

Safely absorbs and disperses kinetic energy and heat from explosive link box failures.

Overview

There have been increased reports of explosions caused by open circuit faults in underground distribution boxes (UDBs) - also known as link boxes. In the event of a fault the resultant expansion may cause the link box lid to be ejected with explosive force, accompanied by hot expansion gases and flames from other combustible items. While rare, these failures can present a serious safety risk to the public and field staff.

Blastguard is an easy-to-install bag of blast mitigation materials that absorbs much of the kinetic energy of a UDB explosion, while also suppressing combustion flames.

It can reduce the height of vertical travel of the link box cover from over 3m to less than 60cm, significantly reducing the risks to members of public and Operational staff in the event of a link box explosion.
