Fire protection materials are not classified perse. They receive a fire rating by the combination of materials in a specific arrangement for the treated point (a pipe or cable, for example) penetrating the fire wall or floor and the construction arrangement of the fire wall or floor. A two-hour pipe penetration fire protection may consist of a layer of caulking over rockwool. Fixing, not caulking, provides the two-hour rating. The individual fire protection materials and the general fire protection assembly are listed.

Certification listings include those available from:.

• - Subscribed laboratories.

• - Canda subscribed laboratories.

• - Deutsches Intitut für Bautechnik (Germany).

• - Efectis (Holland, France and Norway).

• - FM Global[2].

When the installed configuration does not meet the appropriate certification listing, the fire rating must be lowered. When it is difficult to assess the impact, it should usually be assumed to be zero and the building's fire protection plan compromised. Each entry into a fire-rated wall or floor in a building must have a certification listing. There are thousands of listings for various laboratory certifications and tests. Subscribing laboratories in Canada and the United States publish books listing firewall manufacturers that have been contracted by them for testing and certification. Firewalls should be routinely inspected and maintained to mitigate the effects of weather and reentries.

In North America, composite equipment is required when working near electrical conductors; An electrician is required to observe and ensure the safety of the insulation. The Gütegemeinschaft Brandschutz im Ausbau in Germany also offers a passive fire protection course resulting in a Brandschutzfachkraft (Passive Fire Protection Expert) certificate. The types of material used and the skill set required in insulation and firewall installations are similar. Exceptions to the rule that fire protection is the job of insulators include fire devices which are part of the plumbing system and must be installed by plumbers during concrete formatting.

No fire protection

Older buildings commonly do not have firewalls. A thorough inspection can identify all vertical and horizontal fire barriers and their classifications and all flaws in these barriers (which can be sealed with approved methods).

• - Unsealed pipe penetration in two-hour fire-resistance rated concrete block wall.

• - Improper breach of fire-resistance rated drywall assembly.

Unlisted attempts

Firewalls created by contractors or building maintenance personnel that are not listed, sometimes called “condemned to comply,” are not accredited with an adequate building code classification for compliance purposes. They are usually short-term, cost-reducing measures at the expense of fire safety and code compliance. A common mistake is citing a listing for a product which may have another use. An insulation with an active listing of a spray rating is unacceptable for fire suppression purposes.

• - Common concrete, with no testing intended for certification listing.

• - Stuffed fiberglass insulation would rapidly melt and fall out in a fire.

• - Spray fireproofing improperly used to cover penetrations.

• - Polyurethane foam used to fill a cable tray penetration; at Browns Ferry Nuclear Power Plant, this signal resulted in significant fire damage.

Los cortafuegos deben ser mantenidos de acuerdo con el listado y aprobación de uso y conformidad. La documentación de construcción algunas veces incluye un inventario de todos los cortafuegos en una edificación, con dibujos indicando su ubicación y listas de certificación. Usando esto, un dueño de edificio puede cumplir con el código de incendio relacionado con las barreras de fuego. Reparaciones inadecuadas por otro lado pueden resultar, lo cual violaría el código de fuego y podrían permitir que el fuego viaje a través de áreas dispuestas por el código a estar separadas durante un incendio.

Re-entry

It is usually necessary to install new electrical wiring or mechanical systems through a hole in a fire resistant barrier which has been retrofitted during construction. In this case, the firewalls are reentrant. To maintain a building's original fire protection plan, protective reentries must satisfy the certification listing upon which the original configuration is based.

• - Reentry firestop mortar.

• - Opening created for future use in an electrical service room.

fireproof sprinkler

Fire spraying of structural steel is best used before internal partitions are constructed. Otherwise, a conflict with firewalls and fire walls could occur. Firestops must be adhered to the unobstructed, dry, bare surfaces of the fire barrier which is penetrated (metal decoration, for example), or adjacent to an interface of two fire barriers in which fire protection is required (such as beams). Fire spray cannot be applied before fire protection on these surfaces, because the spray could obstruct the adhesion of the resisting materials to the fire barrier surfaces. Spraying the perimeter of the upper zone can also cover the wall or seal joints and through penetrations which require fire protection. These joints are therefore not provided with appropriate fire protection, violating the integrity of the passive fire barrier.

Labeled

Proper maintenance is enhanced by the installation of labels on each side of the fire protection with the necessary information to refer to the documents indicating the approval procedures for the original installation and re-entries. This requires knowledge of the certification listing used for each building joint entry or penetrating through penetration sealing.

• - Firestop tag front, with information needed for proper maintenance.

• - Tag back, for recording maintenance.
