Firewalls are built between or through buildings, structures, electrical substation transformers, or within an aircraft or vehicle. The firewall serves as a fire containment wall between one oil-filled transformer and other neighboring transformers, building structures, and site equipment. In addition specialty fire-rated walls such as a High Challenge Fire Wall would require further distinctions. This allows a building to be subdivided into smaller sections. If a sections becomes structurally unstable due to fire or other causes, that section can break or fall away from the other sections in the building.
The main differences are that these fire resistant walls are not structurally self-sufficient. Fire barrier walls are typically continuous from an exterior wall to an exterior wall, or from a floor below to a floor or roof above, or from one fire barrier wall to another fire barrier wall, having a fire resistance rating equal to or greater than the required rating for the application. Fire partitions are not required to extend through concealed spaces if the construction assembly forming the bottom of the concealed space, such as the ceiling, has a fire resistance rating at least equal to or greater than the fire partition. Portions of structures that are subdivided by fire walls are permitted to be considered separate buildings, in that fire walls have sufficient structural stability to maintain the integrity of the wall in the event of the collapse of the building construction on either side of the wall.
Fire wall must withstand a minimum 5 lb. Firewalls are used in varied applications that require specific design and performance specifications. Knowing the potential conditions that may exist during a fire are critical to selecting and installing an effective firewall. F, is not designed to withstand higher temperatures such as would be present in higher challenge fires, and as a result would fail to function for the expected duration of the listed wall rating. Performance based design takes into account the potential conditions during a fire. Understanding thermal limitations of materials is essential to using the correct material for the application.
Laboratory testing is used to simulate fire scenarios and wall loading conditions. The testing results in an assigned listing number for the fire-rated assembly that defines the expected fire resistance duration and wall structural integrity under the tested conditions. Designers may elect to specify a listed fire wall assembly or design a wall system that would require performance testing to certify the expected protections before use of the designed fire-rated wall system. In the event of an accident, resulting in fuel spillage, the firewall can prevent burning fuel from entering the passenger compartment, where it could cause serious injury or death.
In regular stock cars, the firewall separates the engine compartment from the cabin and can, at times, contain fibreglass insulation. Automotive firewalls have to be fitted so that they form a complete seal. This page was last edited on 28 September 2017, at 20:38. Share with your Facebook friends!

I live in an apartment and from the electric office a transformer is being planted very near my building and outside my window. So , in this circumstance what should I do and what should be the check points and for complain where sholud I lodge them? 2 Pressurized container as the area is hazardous area Please suggest what should be the minimum distance of the transformer from the walls of the container.
