Abstract

If air handling ducts pass through fire-separating elements, the load-bearing capacity, integrity and insulation of the elements should be maintained using one or more of the following four methods. In most ductwork systems, a combination of the four methods is best to combat potential fire dangers.
a. Method 1 – thermally activated fire dampers.
b. Method 2 – fire resisting enclosures.
c. Method 3 – protection using fire resisting ductwork.
d. Method 4 – automatically activated fire and smoke dampers triggered by smoke detectors.
