Pressurisation ductwork is a passive fire protection system. It is used to supply fresh air to any area of refuge, designated emergency evacuation or egress route.[1]
Purpose
[edit ]The purpose of pressurisation ductwork is to maintain positive pressure in building spaces to prevent smoke from entering from other spaces in which a fire is occurring. It is typically used in exit stairways, corridors, and lobbies.[2]
Requirements
[edit ]Pressurisation ductwork is certified on the basis of fire testing such as ISO 6944.
Systems
[edit ]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.
