 Firestop Mortar seal at a pulp and paper mill in British Columbia, Canada. Firestop mortars of sufficient strength and depth, at densities not far above 1 kg/L can absorb heat from penetrants and also withstand the heat induced expansion and motion of ferrous cable trays that are exposed to fire. They tend to be noncombustible and easy to install. Notice that this firestop bears an identification tag, with clear bounding references, such as the applicable Underwriters Laboratories certification listing number, to enable intelligent maintenance.

Germany's GBA (Gütegemeinschaft Brandschutz im Ausbau) also offers an extensive passive fire protection course, resulting in a certificate designation: "Brandschutzfachkraft" (~Passive Fire Protection Expert). In Europe as well as North America, all major firestop installers with nuclear installation experience are, by background insulators first. The German trade designation is "WKSB)" (Wärme, Kälte, Schall und Brandschutz), an acronym that stands for heat, cold, sound and fire protection. On both sides of the Atlantic, these traditions prevail for good reason, as the generic material types used and the skill sets needed are similar, between insulation and firestop installations. Exceptions to the generic rule of thumb about firestopping being insulators' work, includes firestop devices that become an integral part of the plumbing system, which must be installed by plumbers during the forming of concrete.

 This picture shows a typical through-penetration in a timber building. The plastic pipe is the penetrant. Combustible buildings can have fire compartments, consisting of assemblies capable of achieving a fire-resistance rating. Typically, wall assemblies made of wooden studs, must be boarded with "Type X" or glass fibre re-inforced gypsum wallboard, where the installation must consider bounding. Wooden floors are often topped with thin layers of concrete. Through-penetrations for mechanical or electrical services, as shown here, are not formed by sleeving, but by chainsaws that go right through everything. The determining factor for the penetration sizing in this case is the width of the chainsaw blade. Otherwise it is the size of the penetrant that determines the size of the sleeve or block-out.

Ratings A common misunderstanding of firestops is that certain materials have certain ratings on their own. For instance, a two-hour rated pipe penetration firestop may consist of a 5 mm layer of caulking, over top of 100 mm of packed rockwool. The layman may assume that the 5 mm of the caulking provide a two hour fire-resistance rating, generically, regardless of the application. This is absolutely wrong. The mere notion underlines a fundamental misunderstanding of bounding. Materials are not individually rated. Instead, they are used as but components within an overall system or certification listing, that must provide identifiable bounding for the installed configuration. In addition, all materials in and around the firestop must conform to the tolerances shown in the certification listing that covers each such installation, including the penetrants, which may also have their very own bounding requirements apart from forming part of a certification listing for a firestop.

Compatibility
 "HOW" (Head Of Wall) Building Joint: Concrete Masonry Unit Wall stopping short of the underside of a concrete slab above. The joint is penetrated both by electrical conduit (EMT = Electrical Metallic Tubing) and a steel pipe. Building joints are routinely penetrated by mechanical and electrical penetrants. For that reason, joint firestops that are also qualified to be used in mechanical, electrical and structural through-penetration firestop systems provide the best evidence of building code compliance because they have demonstrated the ability to cope with the heat that travels through to the unexposed side during an accidental or test fire exposure - without spontaneous ignition or degradation that would fail the hose-stream test or permit smoke migration. All items within a system that touch one another should have proven compatibility both under fire conditions and operational conditions. For instance, sealants should not degrade penetrants. Cold penetrants may attract dew. Such penetrants should not be in contact with sealants that easily degrade in the presence of water. Also, building joint firestops may achieve very high fire-resistance ratings when tested between two concrete elements with insulation in the middle. Sealants with ratings of B2 per DIN4102 (like timber - normal combustibility) or even B3 per DIN4102 (easily ignited like polyurethane foam) can survive up to 4 hour fire tests because they are protected by rockwool on the exposed side. In reality, however, penetrants are often found within building joints, which are equally sure to conduct plenty of heat through to the unexposed side and right into the sealant. To avoid any heat induced degradation, let alone spontaneous combustion, one can simply restrict joint sealants to those that have already achieved ratings in service penetration firestops.

Common Problems and Solutions Users must understand the role of bounding and the role of firestops within passive fire protection and the role this plays within overall fire protection. Exact documentation for each construction site must exist, complete with an inventory of all firestops in a building, identification tags and a separate set of drawings showing each firestop and the bounding provided by the certification listings used for each installed firestop. Unless this documentation is called for during the planning stages, created during construction and turned over in its entirety to the owner, along with comprehensive training for maintenance purposes, the owner has no way of knowing which hole is firestopped how and why that matters to his or her ability to meet the requirements of the fire code once the building is occupied. One must be able to find the firestops, walk up to them and be able to find a current tag, that is listed on a purpose-designed inventory for each building, showing the certification listing that covers the installed firestop. Otherwise, proper repairs are but guesswork, which violates the fire code. The collection, turn-over and training of this information for the owner is too often absent and is precluded by the practice of having each trade do its own firestopping, whereby the plumber may do some, the electrician may do some, as will the drywaller, and so forth. A separate and complete firestop specification must exist, as well as a line item cost breakout during the tender stage, whereby the firestopper is one sub-contract to the general contractor, whereby one speciality firestop contractor does all firestopping on site, so that he or she can co-ordinate and collate the proper documentation for the eventual turn-over to the owner. Otherwise, up to a dozen different contractors or more could be involved, each using materials from different manufacturers, which are not interchangeable for liability and bounding reasons. With literally thousands of firestops per building, simpler is better. The owner must be given the knowledge to understand the importance and role of firestopping, passive fire protection and bounding to prevent the most common fire code violations, where firestopping is concerned.

| Older buildings routinely exhibit the phenomena of having no firestops at all. In that case, a thorough inspection helps, which clearly identifies all fire barriers, vertical and horizontal, and their ratings. This should be followed by an examination of all these barriers to find all breaches, inventory them and then seal them with approved methods under the auspices of a building permit.

 Polyurethane foam used to fill a cable tray penetration. At Browns Ferry Nuclear power plant, as seal of this nature, covered on both sides with two coats of a flame retardant paint was used instead of a bounded firestop. The foamed plastic caught on fire through exposure to a candle. The ensuing fire caused significant damage to the station. This picture was taken in a power plant in Nova Scotia, where it was subsequently removed and replaced with firestop mortar.

| The "Deemed-to-comply" variety of illegal firestops includes "homemade" remedies, where people invent their own methods without any testing back-up, let alone product certification. These are short term cost cutting measures at the expense of fire safety and code compliance. Common ploys to justify such means include focusing on approvals or listings such products may have for other uses. For instance, one may point out the the fact that one's insulation has an active listing for having a certain flamespread rating. In that example, one may point to an Underwriters Laboratories listing for the flame spread rating, which is deceiving, as UL also has listing for firestops. A UL listing for one purpose, however, does not mean it is in any way acceptable for any other purpose. Product certification or product qualification is the cornerstone of all bounding and the process of certifying that a certain product has passed performance and/or quality assurance tests or qualification requirements stipulated in regulations such as a building code and nationally accredited test standards, or that it complies with a...

| These pictures indicate the need for purposely trained firestop installers who know that the installed configuration must be bounded by an active certification listing. In each of the above cases, the firestops were installed by adjacent trades, either the trade that was responsible for the penetrant or the trade that was responsible for erecting the fire barrier that contains the firestop. Firestopping is a complex matter best left to those who have the resources, training and interest to match up the installed configuration with a listing. When this is not the case, firestopping is often undervalued at the time the job is tendered and in the end it becomes an afterthought, for which there is insufficient money, knowledge and interest to do it in accordance with the building code and fire code. The results lead either to remedial work or an acceptance of conditions that do not comply with applicable legislation. A penetrant is the cause for a service penetration firestop. ...

| These pictures highlight the need to ensure that firestops are not separate add-ons to mechanical, electrical, masonry, drywall and other trade contracts. All components routinely come into contact with one another. The only way to be sure that the resulting installations meet code is to have a specialist, such as a trained and experienced firestop contractor, match up the installed configurations with active certification listings that bound the installations in all respects and that proper documentation exists, not just in the form of submittals by subcontractors up the chain, which the owner never sees, but also in a comprehensive turn-over package to the owner to create the possibility that the owner can perform adequate maintenance once the building is occupied. Re-entries for tenant work typically begin while the main construction job is still being completed. This process of ensuring proper installations and practical documentation begins with a very clear specification that goes with a line item cost, as a sub-contract to the general contractor, along with the required will to enforce the matter post-tender, which is easy enough to do by making a comprehensive turn-over package for the owner for all firestops on site (mechanical, electrical, structural, architectural) with a uniform tagging plan for all openings and joints a required part of the workscope - pre-tender.
Drawing intended to regulate opening sizes for firestops. Without having these essentials in place from the start, mechanical and electrical trades who are obliged to do their own firestopping routinely use the "I-was-there-first-scenario" (justification) for absolving themselves particularly of their responsibilities to properly seal drywall through-penetrations, which can be especially costly and tricky to do, as the drywall article points out. The scenario is one of shifting responsibility. The mechanical or electrical tradesperson hangs the penetrant before the drywall is installed. Anything that happens afterwards, these trades consider to be someone else's responsibility. When they were there hanging penetrants, there was no hole because there was no wall. They don't form the holes so it's not their responsibility. The drywaller's spec does not address firestopping for mechanical and electrical through-penetrations, as this is covered (in North America) under Sections 15050 and 16050 (sleeving), respectively. So, the drywaller cuts and fits as closely as possible, muds up to the penetrants with drywall mud, making the best of it, not having allowed for such elaborate firestopping work pre-tender. This has been known to happen even with combustible plastic piping. In the final analysis, everyone has an excuse why the proper firestops will not be done (at their expense) and in enough cases that is where the matter comes to an end, with the fire safety concept for the whole building in ruins. The remedy is to have a separate contract for the workscope which clearly points out how openings are formed, what sizes they shall have and who is sealing them with what and what sort of documentation is required.

| Firestops are often re-entered, throughout the life of a building, as the pictures show. If the entire fire protection plan of a building is to remain operable, it is imperative that a plan be in place to ensure that re-entries of firestops are done within the context of a plan that is ideally put in place during the design stage of a building. Re-entries of fire barriers by most local building codes require the application for and issuance of a building permit from the Authority Having Jurisdiction. Re-entries must be recorded and re-sealing must be done in the full knowledge of and compliance with the certification listing upon which the original installed configuration was based. This is best accomplished through maintaining simplicity, meaning that the number of trades executing firestop work and the number of firestop manufacturers used during the original construction of the building be kept to a minimum so that the number of repair materials can be kept small and manageable. Each opening should be properly tagged and correspond with documents that are collected by the design and construction team, turned over intact to the owner and be kept up to date by the owner to ensure compliance with the local fire code. Cranes are essential in large construction projects, such as this skyscraper In project architecture and civil engineering, construction is the building or assembly of any infrastructure. ...

| Proper maintenance requires that firestops be tagged, clearly, on each side. The tags must contain the information necessary for bounding - both of the original installation and any re-entries. This requires knowldege of the exact certification listing that was used for each opening, be it a building joint or a penetrant through-penetration seal. The owner is well advised to maintain the records centrally because operating buildings undergo routine maintenance, sometimes by contractors, sometimes by his or her own forces. It is in the owner's interest to keep things as simple as possible, keeping the number of products to a minimum, increasing the likelihood of compatibility between them, as indicated in the Re-entry paragraph above. When one walks up to a firestop, anywhere in the building, one should be able to see a proper tag and the information on the tag should correspond with a separate set of drawings and records, forming part of the owner's evidence of due diligence.

Regulations and compliance When the installed configuration is not in conformance in all respects with the tolerances of the appropriate certification listing, it is not bounded and, therefore, the rating is zero, which means that the entire fire protection plan for the building that contains such a violation of codes, is compromised. For any deviations from this principle, one is required by law to contact the Authority Having Jurisdiction (AHJ) to gain acceptance of a suitable remedy. Cranes are essential in large construction projects, such as this skyscraper In project architecture and civil engineering, construction is the building or assembly of any infrastructure. ...
It is, therefore, necessary to be able to match each opening in fire-resistance rated wall or floor in a building with a certification listing. There are literally thousands of listings by various certification and testing laboratories. Both the Canadian and US Underwriters Laboratories each publish separate books containing just their own listings, whose firestop manufacturers they have under contract. There are at any given time just in North America up to sixty different manufacturers, each with dozens of products, each with many listings. An architect will routinely specify up to ten different manufacturers, whose products are acceptable for use within one construction site. This means several books full of firestop possibilities for just one single building. It is, therefore, entirely logical and highly advisable to label firestops such that one can easily determine bounding, meaning that one is able to look up what listing covers which hole, both on tags on each firestop but also on the shop drawings, which then show all those openings in all the walls and floors, in such a way that they are logically numbered and cross-referenced.

Only in that way, can one perform repairs, which are often necessary. Firestops get re-entered all the time, especially electrical penetrations with penetrants such as cables, conduit, etc., because people often make changes to wiring in particular. Unless one knows precisely what listing covers the firestop in question, one has little chance of being able to determine what materials to use for the repair, or if a new penetrant is even permissible to be used in a sealed opening. Some firestops are listed with repair procedures, others are not. Just because a material "sticks to itself", that does not mean there is any evidence that will hold up in a court of law, that actually proves that a repair was included in the original test. Firestops are routinely misunderstood and incorrectly installed or completely absent. Noncompliances can be deliberate or accidental. Changes to firestops require the notification and approval of the Authority Having Jurisdiction (AHJ), meaning either an acceptance by the fire prevention officer or a building permit. 6 or 15cm outside diameter, oil-cooled cables, traversing the Grand Coulee Dam throughout. ...
Firestops must be routinely maintained and kept bounded, not because they otherwise fall apart (though some have been known to such as North American intumescents based on unprotected sodium silicate without proper DIBt approval), but mostly because of re-entries. The only way to accomplish this AND meet the code is to ensure that separate shop drawings exist, which show all fire-resistance rated wall and floor assemblies and their specific ratings. Next, all building joints and all mechanical, electrical and structural through-penetrations must be shown and numbered on the drawings. Descriptions for each opening must be kept, along with photographic evidence of proper sealing, which identifies each component and the certification listing that covers each installation. Certification listings for firestops are not complicated, but they can be lengthy, with a variety of separate detail drawings.

It is impossible to determine bounding without evidence that the installed configuration is within the tolerances of the applicable certification listing upon which the installation was based. Without this evidence, no proof of building code or fire code compliance can be deemed to exist. Hence, when approaching a firestop, one should be able to see a clear tag that identifies the opening number, which can then be cross-referenced in the overall building's inventory of firestops. Re-entries and repairs must also be documented. Opening numbers found in the field must match those found on the tags. A functional maintenance program must exist, whereby tags are used to identify repair materials and methods, especially in buildings where firestops from more than one manufacturer were used, as there is typically no proven compatibility between firestop materials from different manufacturers, which precludes bounding, which spells fire code violations. That is a very important point. Compatibility between firestops made by two different firestop manufacturers, who compete against one another, has precious little to do with whether or not the two materials bond to one another or whether or not one may in fact help to deteriorate one another. Unless both are included in ONE certification listing, meaning that both have been tested together with the intention and consent of both manufacturers, there is no identifiable bounding, meaning that liability for such a combined seals becomes the responsibility of those who performed and/or authorised the mis-match. Even two different materials made by THE SAME manufacturer, can only be combined in one firestop if a certification listing exists that sanctions the match.
Only with an organised inventory and maintenance scheme does the owner have a chance of being able to provide evidence of compliance, in the event of an inspection or a fire. Tagging is already mandatory in Germany. It is, thus, counter-productive to have multiple contractors in charge of firestopping within one building, as each can typically use different materials and listings, which may or may not be compatible with one another. Unless the contractor who is installing the firestop is an active participant in the firestop industry, meaning that his primary aim is to work in passive fire protection, chances are that bounding details are missed, which jeopardises the entire fire protection plan of the building. While it is possible to achieve the required ratings required to meet the building code using a large number of products, the result becomes hopelessly complex for the owner to maintain afterwards. If the architect permitted the use of products from six (6) different manufacturers, which is not out of the ordinary, who each have twelve (12) different products (which is also not out of the ordinary), which each have 60 listings (which is conservative), the logistics surrounding what governs just one single opening are considerable. To enable reasonable maintenance and documentation for the owner throughout the use of the building, it is necessary for the architect to have a strict master specification in place, which may have to be adjusted to the unique needs of certain buildings, ships or offshore facilities. An appropriate master specification Section 07840 should contain a wide variety of experience-based SPEC-NOTES to remind the specification writer of the requirements for all paragraphs and different project requirements. Just having a Section 07840 will not do though. Pointing each separate trade to it and having everyone do his or her own firestopping is, once again, counterproductive to producing a building where the owner is able to maintain fire code compliance. There is simply too much information to maintain otherwise, which is akin to setting the owner up for fire code violations within weeks or even days of occupancy. It is not unusual for owners to begin to re-enter firestops before the last tradesmen from the original construction have left the building. Firestoppers routinely repair firestops during the last days on the job, that have already been altered with new penetrants for tenant work. Without tagging and training of the owner, fire code compliance becomes an illusion from the first day the keys are turned over to the owner.
