Mangano, Thomas B. The Residential Metal Chimney. Firehouse. February, 1992.

Abstract: This article discusses the usage, construction and, appearance of two types of factory-built metal chimneys, the double wall insulated and the triple wall air cooled system. A firefighter must be able to identify possible chimney hazards at a fire scene. This article explains how to examine and how to identify potential chimney problems at a fire scene.

A firefighter should always inspect the installation to be positive that the chimney is firestopped at every level. While inspecting the exterior installation, a firefighter should note the position of the shrubs. If they are touching the chimney, they could present a hazard. A firefighter should also be familiar with the support box. This box supports the metal chimney and is located where the oil furnace connects to the metal chimney. The floor surrounding the support box should be examined at a fire scene to ensure that it is still able to support the chimney. A firefighter must also examine any cracked flue tiles and missing refractory cement joints because they could cause an extension of the fire.
