Man, Only if every pipe that came through a wall was this easy to do - Most are stuck up in a ceiling with fitters, ducts and wires blocking it and you can barely get your hand up in the spot to stuff rockwool in it! lol

Hi sir. How about if the the pressurization system duct riser per floor is enclosed by concrete hollow block. I would like to ask if it is needed to put a fire stopping sealant every floor in duct riser. Thanks
I've been told that Great Stuff Fire Block is not the same thing as Fire Stop material. While remodeling my home I wanted to block pests (roaches, ants, etc...) from getting through the holes where the gas stove pipes come through. Home Depot associates suggested Great Stuff Fire Block (foam) to fill in the area between the sheetrock and external gas pipe. So I've had the contractor spray the foam. I want to mention that I had capped and shot off the gas pipe since I chose to purchase an electrical stove. However I'm concerned if I sell the home in the future and someone decides to install a gas stove, is there a possibility that the outside of an active gas pipe can reach temperatures over 240 degrees? The manufacturer mentioned that the Fire Block foam can combust when the temperature is over 240 degrees.So far the home inspector can only suggest talking to an expert. The Great Stuff customer service representative is too careful to make any mis-statements (most likely they don't know) and will only mention to make sure the contractor knows the surface area cannot reach 240 degrees. The contractor has a fairly short answer that the outside of the pipe shouldn't reach 240 degrees. It would be really helpful if someone could respond as I'm trying to be proactive.
+dg indc The gas pipe will remain at what ever the ambient temperature is. The gas in the pipe does not burn, only the gas that is released through a burner and the heat does not transfer backwards. For the foam to fail, there would have to be an independent fire or heat source. If what you were thinking was true, gas lines from heating furnaces would cause a large number of house fires and would not be allowed by code. Active gas pipes are actually cool to the touch. You have no reason for concern.
Hello, nice video !. Does anybody know if a Through Penetration of a fired rated wall is also a double Membrane fire barrier penetration of that wall? Thanks.
Many jurisdictions have a defend in place process- Grendel Tower is one example. The last few times I was in a hotel when a fire alarm went off, most people stayed in thier room to wait to see what was happening. So, lots of people will stay in buildings

Jason Alexander's relative?
You have to be careful with scabbing drywall over holes in firewalls in ambulatory and business occupancies it is not allowed
I do firestop in hospitals and have to constantly remove old scab patch work and cut drywall that fits in flush. so annoying
@@metakarbonyou ain’t the only one! My hospital is over 100 years old and they put scab patches everywhere! I
Hi! firestopper here.
My question is who's going to stay inside a burning building to smell the smoke ?
