1. NOT COMPLIANT. In this instance, there are at least two different types of firestop product being used in conjunction on these penetrations. Mixing different manufacturer’s products in the same penetration is not acceptable.
2. NOT COMPLIANT. This is an example of joint compound installed as firestop. This will NOT provide an effective seal to stop smoke and toxic gases in the case of a fire and is not an acceptable firestop material.
3. COMPLIANT. Note the professional appearance of the firestop sealant. These penetrations are firestopped properly with the same product and installed correctly to UL system specifications.
4. NOT COMPLIANT. Again in this picture, there are at least two different materials being used in the same penetration. Mixing different manufacturer’s materials is not an acceptable and would not hold up in the case of a fire.
5. NOT COMPLIANT. In this photo, we see multiple cables firestopped with filler foam. Filler foam is not an acceptable firestop material. Therefore, this system would not pass an inspection or hold up in the case of a fire.
Ensure Your Compliance
There are many factors that must be taken into consideration when addressing penetrations in your fire barriers. Here are a few things to remember:
Firestop products are not rated. UL systems provide the fire resistance rating, so it’s important that the correct UL system is used for each penetration.
Mixing different manufacturer’s products in the same opening is prohibited.
No single product works for every application. Every penetration is different and must be firestopped appropriately.
Maintain accurate and thorough documentation with before and after pictures, to provide to any AHJ (Fire Marshel, CMS, TJC, etc) during an inspection.
