Rollover, Flashover and Backdraft in fire simulator. (Brandverloop)

13:05 for backdraft

I'm studying to become a firefighter so I'm still learning, please let me know if I got something wrong! 6:40 - Rollover - the flames, rich in vaporized combustible, are hot enough to ignite itself, releasing a lot of heat, contributing for the next step 7:15 Obs. This goop on the glass is soot + water, combustion products, and it will take over the whole glass until the end of the video. 9:06 - Flashover - the room is so hot that even the material that is not near the fire focus gets hot enough to ignite. This usually takes just a second to ignite the whole room. 11:18 - Obs. They tried do do a backdraft but there was not enough heat yet, maybe if they had left it burning for a few more seconds would be enough, who knows. So they add heat 'artificially' to get to the ideal point. 12:00 - Flameover - here you can see the smoke getting out of the container is burning by itself. Just the contact with O2 is enough to burn it. It's a sign that the smoke is hot and concentrated enough so a backdraft is around the corner. 12:54 - Backdraft - They closed the container and the fire extinguised because of the lack of O2. But the smoke is so hot that when they open it again, the container "sucks" the air rich in O2 and the backdraft happens. It's probably one of the most dangerous moments for the firefighters. More OBS. the smoke is with high concentration with CO, which is a product from incomplete combustion (complete combustion product is CO2, not inflamable). CO has a high inflamability range (12% - 74%) and is a reason to the blackness and density of the smoke. Edit: I passed the exam btw

13:29 It's amazing that the guy in the box never seems to burn

love the use of clear cover on the front, great work

I came for the birds but stayed for the fire.

Rollover starts at 6:34, flashes at 9:10.

Wow pretty cool and amazing how it shows why to stay low to the ground and crawl before the fire obviously catches the whole room on fire. It's amazing while the backdraft happens when its searching for oxygen and once it does it just erupts

Now here’s a relaxing training video!! You’ve got natures symphony playing in the background. 🥰

Hi, great job ! Can you explain how did you build this "training fire box" please ? and what kind of glass did you use ? from an oven maybe ?

the flame coming out of the left outside of the box is entrainment. smoke is flammable and this is the smoke combusting and fire traveling through it.

Amazing simulator, are you selling/listing your specs and materials? Would love to build this for an academy.

Narration dubbed over the video would have made it much more powerful.

The breath u can See is amazing...that looks so beautiful

Fantastiese demo meneer, dankie.

Awesome video thank you!

Good video thanks!

My new favorite Yule Log video 😉🎄

You also have inception/growth/fully developed/decay phase really good video in doing minrescue very accurate video of what's in the book

Great to see the development of the fire from the cross section view, any chance the video could be reedited to include the thermocouple temps in the bottom left corner?

Is there away you could let me know how you built this? Great way to show my crew what a flashover is and does, would love you recognize your prop that could help others to understand signs and save lives.
