As a fire engineer, I have to say: extremely well done! I liked your focus on stay put/shelter in place policies, that’s generally what we want people to do in the UK. However, as this is for an international audience, I’d like to touch on a few points: Know your building Get familiar with the plans and notices posted in YOUR building. Know and follow their advice. Know your escape routes. Know what to do when you hear the fire alarm go off. This goes for your home as well as your place of work. Don’t fight the fire Unless there is a very small fire, outdoors, on a calm day, you a) won’t be doing much with a fire extinguisher anyways and b) risk smoke inhalation, which has extremely dangerous short and long term effects. Stand up for your fire safety Make sure access and egress routes are clear. Talk to neighbours who block the hallways with unnecessary items. Don’t let people park illegally in fire lanes, not even for a few minutes. Demand that your buildings fire equipment is serviced regularly, make sure fire doors close well and close automatically. If your building managers refuse to do something, talk to your city’s fire department, they can conduct an inspection and enforce the fire code. Get involved Some cities have volunteer firefighters, others have other volunteer positions. If you want, get involved, they’ll be happy to welcome you.

Other aspects of your video I’d like to comment on: Sprinklers Sprinklers are, as you said, an additional layer of protection. Without other measures like working compartmentalization, their effectiveness is limited, at least in a residential setting. External insulation External wall insulation, like styrofoam based cladding, can be a risk in high rise buildings, if it doesn’t respect the compartmentalization and spans multiple units without fire breaks. The most prominent example of this is Grenfell tower, which did prompt further investigation and updates to fire codes and procedures world wide. All in all, a fantastic video with well researched information. I loved that you linked additional resources in the description. Thank you!

@@dgnikon There is no way I'd stay in place if I lived in one of these towers. Doing so puts your life in the hands of multiple layers of people doing their jobs properly. And frankly, that right there is the whole absurdity of staying in place. Keeping the fire isolated to one part of the structure requires the architect did their job properly, the builder including all subcontractors all did their jobs properly (adhering to fire codes) and (as in Grenfell Tower) no unsafe modifications or additions have been made to the structure that completely compromise the isolation system. Of all the things I've learned over the years, trusting people to do things properly isn't one of them. Experience has taught me people are stupid, moronic, lazy, unskilled, inept, take shortcuts out of laziness or penny pinching (upping their profit), don't do their research (Grenfell Tower insulation installers), don't care (Grenfell Tower insulation installers), and building inspectors suffer all of the above which is why things like Grenfell Tower happen. Staying in place requires trusting ALL THESE PEOPLE to have done their jobs properly. WTF? If I lived in one of these structures I'd have full face masks and 15 minute air tanks for them, for myself and all my family members plus a couple spare for guests. And the same number of fire blankets. And if a fire did break out in the building we'd leave and nobody would stop us. Portable air and leaving at the first opportunity would have saved everyone in Grenfell Tower.

Firefighter from the U.S. here. I love what you said near the end about the dangers of house fires next to highrise apartment fires. Houses built in the modern day are filled to the brim with synthetic materials, like plastics and foams. These building materials, while significantly cheaper, are also extremely dangerous in fires. When they burn, they give off extremely toxic byproducts, be it by smoke, or gas. Another thing that you touched on, but I really want to emphasize. ALWAYS SLEEP WITH YOUR DOOR CLOSED!!! This gives you waaayyy more time to react to your smoke alarms (assuming they work, of course (change the batteries when they ask you to, please!)) and either escape, or shelter in place effectively. Even those cheap and hollow interior residential doors can keep you safe from extreme heat or fire for several minutes.

I work for a big city FD and the biggest problem we have in appartement buildings (low and high rise) is people wedging fire doors open or interfering with the automatic closing systems. It basically bypasses all the protection of a fire break and spreads smoke everywhere. It's more common in poorly maintained buildings often owned by slumlords but I've also seen it in public housing and expensive condo towers. Only a few days ago we ran a 3am call for a small trash fire in the basement garbage room of a 4 floor 60 apt building, all the hallway and stairs fire doors were jammed open so though the fire was small and never spread from the room, all the stairwells and hallways were filled with smoke. It happens too often.

Exactly, sheltering in place depends on these complex fire proofing systems to actually work. And it requires the Grenfell Tower not to happen where combustible material was used in the construction. I don't care what anyone says, it's safer to evacuate buildings while it's safe to do so rather than tell people shelter in place until it's no longer safe to evacuate. I'm not sitting around counting on a complex fire proof system to save my life when we have multiple examples of it getting people killed and there's 0% chance of me burning to death OUTSIDE the building.

The extent of my fire training is stop drop and roll. I believe if we took the time to really educate people and let them know an open fire door is literally the difference between life and death almost no one would prop them open. And if someone did they’d probably be policed by others. But ofc people don’t care when no one really understands the significance of them. We just see them as the heavy doors that are always trying to close on you.

One of things that's also important is the consistency and sensitivity of the building's automatic fire detection system. This past summer, I lived in a newly constructed apartment building that has per suite fire detectors, automatic fire doors that are opening during normal use but closes when the system detects a fire, insulated fire escape elevators, and many other advanced features. The only problem is the overly sensitive fire detection system kept triggering and ordering whole building evacuation from people smoking weed in their apartments. After the third such evacuation, 90% of the residents no longer evaculate, which meant the state-of-art automatic system in advertently caused more complacency due to an incorrect setup.

Good video about fire safety and how to properly react to fires in buildings. I work as a fire sprinkler engineer, and noticed a couple of small errors, nothing that changes the overall message of the video just things that bother someone who does this daily. For standpipes, the GPM coming out of them is dependent on what class they are which is dependent on the type of building it is in. While there is a class of standpipes that is rated to give 150GPM, most are rated to output 250GPM out of at least two outlets simultaneously. The response time of sprinklers comes in two varieties, standard response and quick response. You are correct in saying that townhomes and apartments are required to have quick response sprinklers, but many commercial buildings have quick response sprinklers as well. For the commercial sprinklers it does depend on what the building is used for to decide the sprinkler, as an office has much less fire capacity than a paper mill. I also feel like it does a disservice to not mention the codes that govern this design such as NFPA, and FM global data sheets. Feel free to ask any question about sprinkler systems and I will try to answer them best I can.

13:30 "you are usually safer staying in your own flat unless heat or smoke is affecting you" I mean.... that WAS fine advice in for instance the UK for a long time, until about 2 decades ago when they started allowing buildings to have their facades refurbished with composite panel cladding containing polyethylene or polyurethane foam insulation; and then as billions around the world saw in 2017 it turned Grenfell Tower into a giant barbecue for people, killing dozens. I'm in the US where this was never allowed for high-rise buildings, so I don't know if they've been able to remove all that cladding on every affected building in the UK so the original advice is true once again, but I doubt it. Anyway, there are plenty of other countries around the world where lots of buildings have the same problem, no recognition of the danger, and little to no oversight on matters of fire safety, so you always need to know the specific situation your particular building is in wherever you are.

These fires are found when the entire roof burns out or you find the burnt fan and decided to replace the entire metal housing (the fortunate thing I did) and feel heat pouring out of the attic You could install fire alarms in the attic, or there are fire extinguisher ‘bombs’ that set off from some heat and put out all fires in a smaller space

You can usually extend that to an entire hallway for one level of a building if you open the "exhaust" at the end of that hallway, (it's not really an exhaust, just so there is a flow of air and not smoke from the fire pushed through the cracks as there is no where for the air to go).

i didnt beleive mt school when they said that the building got a 10/10 on the fire safety test conducted by the Ministry of education and higher education, until i saw this video, the school also taught us to stay un our classrooms and activate the fire expulsion system, the building had every safety feature you just showed, i feel much more confident that im not gonna burn to death at school now

Tip: if you ever get stuck in house or apartment due to fire complete blocks your emergency exit. Go to bathroom if you can, turn on shower to keep your self wet and open the drain cover from shower stall or overflow tub cover, place long tube into drain to breath air or smash the toilet out of way and place tube into flange to get air.

I used to live in Sunnyvale, CA and our apartment building code dictated heavy fire doors on each unit at the hallway. (This was a 3-story building with 135 units.) My current apartment, built in 2016 in San Jose, CA has flimsy wood panel doors that you can stab with a screwdriver (happened to a neighbor). It's 6 stories high, 102 units, wood frame construction. Our instructions are to use the fire exit stairs any time our smoke detector or the building fire alarm goes off. However, most people have stopped evacuating because there are so many false alarms. Some tenants tamper with the wiring (because they're tweakers?) and the system goes off at intervals until repaired. Other tenants just pull the fire alarm in the hallway because they like to see the fire department roll up with lights and sirens. (The fire department hates our building by now.) We also haven't had building-wide alarms when there were fires because of all the damage to the system. However, the fire sprinklers have always worked to keep fires limited to the apartment where it started, even when there is smoke in the hallway after tenants opened the door to air out a cooking fire (and the chemicals from the stove hood fire stoppers). Each studio apartment has a sprinkler in the kitchen area, the bathroom, the living area, the sleeping area, under the overhang in the sleeping area where the bathroom fan exhausts outside, both enclosed closets, and the area between the closets. The main problem here is flooding of the adjacent units and everything below to the ground floor.

Building engineers are the real hero's They are the ones who truly save lives. This is why the number of structure fires have dropped dramatically over the years and why fire dept's have resorted to having to needlessly chase Ambulances to keep their call numbers up in order to justify their cushy high paying jobs. The public are so mislead about the truth. Sad how the people who truly deserve the credit seldom get any mention or glory by the media and others like Firefighters are so glorified by them.

Here in New Mexico a lot of buildings use Stucco which helps wonderfully. In my neighborhood the exposed pilot light to an old water heater ignited paint fumes causing the garage door of the building to shoot across into the street. The house was burned from the inside, the owner wasn't home at the time and survived, and the fire never left the property despite the large amount of flammable waste in the house.

Very informative video! I learned a lot about fire safety. For clarity, please consider replacing the word "as" in your scripts to show causal relationships. Since "as" is used to mean "concurrently," and to compare, and it's used in various types of grammatical clauses and phrases, its meaning can sometimes be unclear until the sentence has concluded. Therefore, using the words, "since," "because," "thus," and "therefore" make cause and effect relationships unmistakable. Thus, your content's information will be easier to digest for those with focus issues, processing issues, and those for whom English is a second language. We can absorb your wonderfully presented information without mentally re-contextualizing something because we thought you meant "as" to convey "meanwhile" when it turns out you meant "since." Thanks for all your hard work!

The conclusion is great, one extra factor is the sheer number of extra high rises that have been constructed around the world, often in newly developing areas that haven't gotten everything right immediately because they haven't been building many of them until recently. Yes they could copy-paste general rules and regulations from successful regions, but a good portion of the technical know-how of HOW to design all the intricacies of a great high-rise building are just hidden behind these successful property developers' private archives that new entrants don't have all the answers to. So just because they've just been building so many and each of them house so many more people than houses, you're seeing more news coverage on them.

Thank you for posting this video. It is especially timely, since so many people will be in some kind of public or recovery housing after the floods, hurricanes and fires, and it can be argued that many of them will be elderly. There is a grasping for contract dollars while skimming of duties that lead to bad outcomes, but there is also opportunity to build local capacity and eliminate bad builds. Firefighters will have to go into any mess that happens, and their risks should not be increased by 'good enough for this job'.

After years of consistent false alarms with one siren installed in my bed room... I made the siren more accurate by smashing it to pieces. So far it's accurate all of the time and I reduced the risk of getting disoriented by the extremely loud noise. I no longer evacuate the building when I hear the alarm in the hallway. I give fire-fighters the middle finger when they come tearing through the street with ear piercing alarms on their way to the next false alarm risking lives of other road users. I did learn something though. I took the powerful restraint off my fireproof front door because it was unusable that way. Still not putting it back but I try to remember to close the door behind me when it's on fire. What I do to prepare when the alarm goes... I inspect my apartment for fire, smoke or smells. Then inspect the hallway and inspect the building from my balcony and go back to bed. I am familiar with the official escape routes and have an alternate involving some climbing and a ready rope. Screw the regulations. They are hamfisted and stupid. Meanwhile my building manager refuses to deal with the grease saturated and blocked rangehood ducts which in fact are a huge fire risk. They refuse to keep the concrete stairwell clean which has gotten rather slippery. And at one stage refused to remove stored furniture from a fire escape route. I hope you can understand my attitude towards fire regulations.😮

Listen to older people so you don't have to learn the hard way. Space heaters and extension cords are dangerous fire hazards. Dryer lint traps need to be cleaned and so do the vents behind them into the wall to prevent lint backing up inside the machine and catching fire in the hours while you sleep. Watch out for carbon monoxide and change the batteries in all the detectors. Ovens, stoves, and other appliances need to never be left unattended. Never cut the safety lid switch be bypassed on a washing machine, especially if you have kids or if you don't want to be criminally liable. Do not park in the grass with your hot muffler/exhaust system/motor, etc. Know how to contact emergency services and have a backup plan in case they take 12 minutes to answer and two hours to get out to you (both true stories). Know where hospitals are. Don't smoke in bed. Don't force people whose faces flush to drink, or anyone else. Don't mix cleaning chemicals or use bleach or ammonia containing cleaners in enclosed areas. Don't ignore slip hazards. Don't leave kids and small pets unattended in places where predation exists. Kids can easily be lost in mountains and cover a lot of ground quickly, with all the hazards. Water is always more dangerous than it looks and can down you in shallow water by speed over rough rocks or sweep the sand out from underneath your foot at the edge, etc. Riptides kill. Undertow kills. Do not underestimate natural disasters just because the last one seems okay or someone said they didn't have a rough day. Do not leave guns where anyone can get at them or the ammo. There is a lot more to know, but young people need to stay close to older people who already know this stuff.

Not only is it important for these systems to be installed properly when the building is built, it's also critical they be maintained and tested on a regular basis. I have been involved with testing fire protection systems in buildings for over 20 years, and it's disturbing how little thought is put into maintaining the fire protection after the building is complete. Not only that, but the indifference that is felt by residents that live in the building during testing. I have many examples where testing these systems are "inconvenient" or a "nuisance" for the residents of a building. You don't realize this is done to keep you safe! In my career, I have seen buildings I have inspected burn to the ground, but everyone got out alive. Don't take for granted these systems or the people that keep them working.

In other words, putting scores of people in tall buildings that look like torches waiting to be set alight _can_ be made safe provided highly trained, conscientious architects and builders build them and conscientious inspectors inspect them and _all_ the occupants take fire safety seriously and never wedge a door open despite the great inconvenience that causes. But there is no guarantee of any of that. Designing a tall torch-like building is like designing the material for an inferno. And if the first generation of architects, builders and inspectors are conscientious, everyone will think fire safety is not an issue and will therefore take it less seriously and then there will be a fire.

Smoke inhalation is the No. 1 killer of people in a high rise fire. High Rise buildings that don't have fire sprinklers are more likely to develop the kind of smoke and flames that kill people than buildings that have fire sprinklers. In the U.S. the NIST recommended that all high rise building should have a redundant active fire suppression system (Fire Sprinkler system or similar) to protect against "single point failure" of active fire suppression systems. Self contained fire sprinklers that use a small amount of water mixed with Firefighting foam and compressed air can be installed in each unit functioning independently of single source fire sprinkler systems that rely on a single fire pump located at the base of the building.
