Abstract:
1. A method for remotely forming a barrier to seal off an area of a remote chamber involved in a fire, the method comprising the steps of: a. forming a borehole that communicates between a first location and said remote chamber, said borehole opening to said remote chamber proximate a desired location for said barrier between the desired location and the fire; b. inserting a conduit through said borehole to extend into said remote chamber; c. introducing a flowable material through said conduit to said remote chamber and dispensing said flowable material from said conduit to the desired location for said barrier, said flowable material upon being dispensed producing a substantially solid, self-sustaining composition; d. maintaining dispensing said flowable material to produce a sufficient quantity of said self-sustaining composition to form said barrier, while ensuring that said composition does not block said borehole from communicating between said first location and the fire; and e. thereafter removing said conduit to allow access to said borehole.
