The stopping design is based upon a tough woven flexible fabric material held in place by mesh, chemically anchored roof and rib bolts and a specially shaped washer assembly. A blue coloured impermeable bonded layer is used to seal each side of the fabric to provide important fire resistant anti-static (FRAS) properties. Full scale explosion pressure tests were successfully conducted on the 2 psi Quickseal at TestSafe’s Londonderry NSW facility.
