There are few 'original' Firestop Products. Most of them 'borrow' from other technologies. When you check the history of firestops, as well as the individual product links below and in each link bar on each page of this site, you can see the evolution of it all. We started with 'stuffing tubes' on combat ships. So now you have metal work plus insulation - two trades. Enter the MCT and you add rubber modules. Now we have metal, insulation and rubber - three trades. At this point, more people see that maybe there is $money$ to be made. Imagine the gazillions of holes everywhere! (Little do these early entrepreneurial adventurers know that most people would rather amputate something than spend money on this!) Enter the firestop mortar - cement, trade number four. And on it goes, adding caulking, and paint and refractories and so forth. Most of these base technologies are augmented or altered in some manner in order to lend added desirable effects. One of those effects is intumescence. Another effect is that of added endothermic properties. While this evolution has grown from other technologies, the necessity of bounding remains. Still, it is in the product evolution that problems of confused trade jurisdiction and illegal firestopping are rooted.


The idea of this page is to give a broad overview of the types of technologies that firestops have borrowed from and the effects that resulted. I'll also offer the one golden rule of passive fire protection product design: "Stay as inorganic and a wet as possible." Why? The more organic, the more there is to burn. Why wet? Remember Chemistry 11 and Physics 11 in high school? A change of physical state requires a large amount of energy. Water contained in passive fire protection systems must be spent before temperatures on the unexposed side of the seal will exceed 100°C. The longer you 'flatline' at the water boiling point, the longer your assembly will last. As soon as your temperature readings creep up past the 100°C point, your goose is cooked because you can't get much higher than 140°C (once you jump above 100°C, it does not often take long to reach 140°C because there is no water left to help you) before you start failing T-ratings. Check the endothermic page on this one. Organics can have the advantage of flexibility or pliability, which can be useful in compensating for motion (such as spray fireproofing on LPG spheres or moving pipe penetration seals). However, organics have a habit of supporting combustion. Even intumescents and endothermic materials can burn, insofar as their organic bases are concerned. Sometimes one cannot do without organics, but the smart money is on avoiding them wherever possible. The biggest blunders and the inevitable cover-ups (see 'skuzzbuckets') were based upon organic voodoo. Inoperable endothermics and intumescents are prime examples of this. The cover-ups and weasel clauses alone, to hide these deficiencies are incredibly expensive (sometimes the cover-ups cost more in fees than actually fixing the problem in the building). Say you have an inoperable organic passive fire protection product all over your building. To deal with this in accordance with the law (which remains largely, cheerfully and knowingly ignored in this country particularly with existing buildings) and in such a manner that allows you to sleep at night if you have a conscience, a rare trait in this racket (public OR private sector) you will likely have to evacuate the building and shred into all sorts of finishes, find the stuff, remove it and replace it. Currently, this means that you can pretty much close 95% of educational and health care facilities in this country. In fact, you could close all telephone exchanges and power generation facilities and many manufacturing plants. This general malaise is due not exclusively to bogus products but primarily to the complete absence of bounding (through a combination of disregard, nonchalance and outright cheating for economic gain, routinely tolerated at the highest levels). This is why no Canadian political party or enforcement body has the balls to tackle the subject as their own laws require them to do. The reason for that is that people expect people to die in fires. The fact that more people die because of fires than 'necessary' because we choose to ignore the law and permit violation of existing regulations requires more attention span than is necessary for adequate press coverage to force politicians to give better back-up to our code enforcement community, who now get in trouble when they do their jobs as vigorously as they should. Quite a statement isn't it? Why have a law, which we have no balls to enforce? Does this separate us from any banana republic? But back to your example of the inoperable organic fire protection product in your building. Let's say your building is held up by structural steel beams and columns. Let's further presume that you've discovered that those were protected with an intumescent spray-applied fireproofing material, which quits working within 5 years, which is perfectly acceptable in Canada and the US and can still meet code. The one year warranty does not do anything for you. As a baseline, you would simply have been better off with cementitious spray fireproofing - totally inorganic. It's like a very light concrete. It works because of its density, water content and physical structure. No chemical voodoo that has to kick in at a later date - maybe! In terms of the firestopping, the specification on this website is intended to help the novice navigate such pitfalls. Follow the links below, or on the link bars on each of the pages:
