There are two means of providing fire-resistance rated ductwork: Inherently fire-resistant, or proprietary factory assembled ducts which are made of sheet metal shells filled with mixtures of rockwool, fiber and silicon dioxide; Sheet metal duct with exterior fireproofing materials such as blanket rockwool, ceramic fiber, or intumescent paint.
Smoke exhaust ductwork, in Europe, is typically protected via passive fire protection means, subject to fire testing (typically to NBN EN 1366-8 [1]) and listing and approval use and compliance. It is used to remove smoke from buildings , ships or offshore structures to enable emergency evacuation as well as improved firefighting.
Fire/smoke dampers are similar to fire dampers in fire resistance rating, and also prevent the spread of smoke inside the ducts. When a rise in temperature occurs, the fire damper closes, usually activated by a thermal element which melts at temperatures higher than ambient but low enough to indicate the presence of a fire, allowing springs to ...

A round galvanized steel duct connecting to a typical diffuser Fire-resistance rated mechanical shaft with HVAC sheet metal ducting and copper piping, as well as "HOW" (Head-Of-Wall) joint between top of concrete block wall and underside of concrete slab, firestopped with ceramic ...
In North America, grease ducts must be in compliance with NFPA 96 as well as the local building codes and fire codes. [citation needed]A proprietary duct system that has its own inherent fire-resistance rating can be used, such as a metallic duct, either field fabricated or UL certified factory-built designs.
The majority of guidance available for design of heat and smoke building vents installed in buildings is restricted to nonsprinklered, single-story buildings. [4] This is partly a historical consequence of the installation of heat and smoke vents following the August 1953 General Motors, Livonia, MI major fire in a nonsprinklered manufacturing facility which effectively stopped the production ...
