What if the air puts too much pressure on the door so tenants cannot open door as once the system alarms too much pressure is on the door for a renter to open it.

how the smoke pass through the glass? 🤷‍♂️🤷‍♂️🤷‍♂️😹

I’m still none the wiser, how do you create a fire safe stairwell in an open plan setting?

wtf did speilberg direct this action sequence?

thanks for the explanation

Thanks for that. You see the brass panels you mentioned that say things like 'Smoke Outlet from Basement below' and the like, well, my dad made thousands of those when he worked in a foundry in Dartford in the early 1970s. I've got one on my desk right in front of me as I type this.

There is a typo in your recap slide at 1.32 that says 'Type 2 FRA' when it is recapping type 1 FRAs. Otherwise a good summation

Thank you so much, i was searching for the answer why so many people died, i couldn't understand how the trench effect work, i mean i READ the explanation,but it's absolutely not the same as actually WATCHING it

But the smoke extractor also burns the building down quicker. 😂😂

So, would you compare evacuation drill against ASET as your benchmark to evaluate your evacuation performance? Or are there other means/benchmarks to measure evacuation performance (in terms of time)?

This is some fine work.

That was really interesting! TIL that they do MORE than just let in light to the basement area. I'll definitely remember this next time I walk over them :)

Very good. As a commissioning engineer for these systems it’s very well explained.

Absolute corker of a smoke vent! 😃

Naive question: how do the ventilation systems avoid feeding the fire with air?

Thank you for your video I would like to ask you question regarding the air release, you mentioned it’s needed away from the protected zone. Do you mean having apertures around fire area ? I am confused with the air release sorry 😅

Thanks, very interesting.

Self Note: go to the website

Exactly the overview I was looking for! Really useful - thanks.

what is the function of metal lathe in fireproofing?please explain

Can i use this animation in my video presentation??

No nonsense in 2 min. Great.

😩 'promo sm'

Very well explained and presented

Never installed one but sure went thru many access hatches.

Hot air rises! End of!

Please explain its working in short

What is the name of equipment sir?

That was a horrible night! Thanks for the explanation.

This video would have benefitted from some diagrams or photos.

Would like explanation on co2 snugging units used on industrial tanks offshore.

I have a quistion if you dont mind, so the only way to calculate the RSET AND ASET are only by CFD models or it can be done by hand calculations?

@Sertus is this system ideal for homes?

We're so glad we've finally launched the SND-R! 🔥

How to Design and fan capacity calculations??

I’m not understanding A.5.1.C. If the minimum dimension in any direction of the smoke shaft is 0.85m2 then this gives a minimum cross-sectional area of 0.7225m2 so where does 0.6m2 come from?

Clear overview.

Any questions? Don't hesitate to contact us! 😃

u Cute :)

Thanks for this!

Thanks❤️

Thanks for this - just experienced a hotel fire where the staircase filled with smoke and entered the corridor. Trying to understand if this is acceptable or not. Thankfully there was one other fire exit staircase and the main staircase. See my latest "short" video for what I recorded.

Thank you so much!! Gosh i have test tmr and you save me ❤

Can you suggest some book that cover basics of fire engineering.

Very helpful, thanks!

Very good 👍

Fantastic informative video 👏👏

Cool bro thanks

Great content guys, thanks for this. Just had a few queries with regards to this topic in light of the BS9991 2021 draft: How would you incorporate an air release path within a high rise single stair building with pressurisation given there is no access to the facade from the common corridor? If the system design criteria is the same (pressures / velocities), then would the sizing of the openings also be the same? Also, for a common corridor with an extended travel distance in a high rise single stair building, what are the implications of an independent MSVS (required to justify the extended travel distance) working in conjunction with the required pressurisation system, and how do you think this can be overcome?
