Editing Firewall (construction) (section)

==Applications==
Firewalls can be used to subdivide a [[building]] into separate fire areas and are constructed in accordance with the locally applicable [[building code]]s. Firewalls are a portion of a building's [[passive fire protection]] systems.

Firewalls can be used to separate-high value transformers at an [[electrical substation]] in the event of a mineral oil tank rupture and ignition. The firewall serves as a fire containment wall between one oil-filled transformer and other neighboring transformers, building structures, and site equipment.
