Passive Fire Protection

The intended implementation of passive fire protection is to show how materials can be protected at temperatures at or below either 140°C for stuff like floors, circuits and walls that need a fire resistance rating or 550°C, which is known as a vital temperature for structural which could lead to damage.

To make this happen several different materials are used in making these systems. Endothermic materials for example are made with gypsum and concrete based wallboard. When the testing for passive fire protection is underway with concrete floor slabs hotter temperatures typically boil out of the structure. When a fire occurs, gypsum based materials usually crumble. Therefore proper measures must be taken in the way of creating protective materials to combat against such potential destruction. Many building codes are aware of this and do their best to ensure industry standards are met.

PFP measures that are made with the intention of holding in a fire and their intention are to limit the spread of fire and smoke for a limited period of time. Building and fire codes usually dictate how these measures will be enacted. The safety ratings and their limitations are stated on the certification listing.

Like the title states passive fire protection is able to be very clandestine until an actual fire states. There are two primary classifications of PFP, one known as Intumescent Fire Protection and Vermiculite Fire Protection. In the latter steel made materials are protected with vermiculite based materials in an often thick layer. Compared to the Intumescent protection this is a less expensive option. However their appearance is not very pleasing in the visual department. Intumsecent Fire Protection is a special coat of paint which is spread onto the structure.

Other thing to be aware of with this type of protection is the dry film thickness this is figured out by dividing the heated perimeter by the cross sectional area. Because of Intumscent coatings only go at about 350-700 microns and it doesn’t corrode this is a typically preferred means of protection. Its level of performance is a very reliable one and it’s not an eyesore on a building structure. This makes PFP based structures a widely chosen option amongst those who want to get the most out of their building protection.

The idea of passive fire protection basically is that it’s a bunch of structures inside of structures. Take for instance something like a firestop it is a setup that is integrated with a product certification listing. It then works with other structures within the building such as walls or floors and they form one major fire defense system within your structure.
In essence this makes your PFP based structure one giant entity.

In fact a properly maintained and designed structure that utilizes proper passive fire protection is a force to be reckoned with. If we were betting men we would say that what you would have is such a formidable building that it could even withstand an assault from the Darth Vader’s Death Star! Forgive our attempt at humor but nevertheless the use of PFP will definitely ensure a structure as sound as a pound!
