Abstract

Abstract A B S T R A C T A fire-resistant seal for application to a structure, comprising a holder for securing to the structure, the holder comprising a tubular portion, a fire-resistant barrier material which swells under fire-conditions being retained within the tubular portion of the holder, the tubular portion having an elongate actual or incipient opening extending therealong, the holder also comprising a lateral extension, the lateral extension and the tubular portion of the holder together forming a groove, the opening being in the side of the groove and the lateral extension constituting a guard for the opening. The guard may serve to conceal the opening from view and/or to obstruct the introduction of a straight probe into the opening by a tamperer. When the seal is exposed to hot smoke or flame, the fire resistant barrier material swells and exudes through the opening of the seal to form a fire-resistant barrier.
