Smoke exhaust ductwork
Wikimedia Commons has media related to Smoke Exhaust Ductwork.
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. In North America, fireproofed ductwork may be used for the purpose of smoke exhaust, but it is more common to use unfireproofed return air ductwork, whereby no fire testing or listings are employed to qualify the ductwork for this use.
Means of construction
Smoke exhaust can be built using:
- ordinary sheet metal with external fireproofing treatment; or
- a proprietary duct that is inherently fire-resistant; or
- Fire resistant materials, such as calcium silicate.
