To by mě zajímalo, jak by chutnaly vuřty nebo klobásy opečené nad tím požárem. To kdysi na stavbě zedníci ze Slovenska pálili stavební dřevěné podlážky a pak přiložili celé dveře a když se to pěkně rozhořelo, tak přivalili ohromnou pneumatiku z traktoru a vyndali si uzeniny z batohu, napíchli je na pruty a začali si je opékat a libovali si, jak jsou super opečené..

very good explanation for IBC'S FLAAMMABLE LIQUIDS HASARDS

Cool to know

I’m an inspector in the sprinkler division for Hampshire Fire Protection. Started in January. Watching all of these dry/wet system videos has been a huge help. Thank you so much. Keep up the great content.

Burns slower than wood, compare that to li-ion or -lipo wich litterally turn into omnidirectional flamethrowers

The best are the best! Success. Keep it up!

The "pre-plan" and other plans at the FM insured QVC warehouse in Rocky Mount, NC didn't work out so well. According to the ATF report (which failed to find a cause for the fire), "The fire, now declared to be the largest structural fire in N.C. history, claimed the life of employee Kevon Ricks and destroyed approximately 75% of the 1.5 million square foot facility." Can't be sure, but from pictures it would appear the MFL walls held. Must have been a big loss for FM. I wonder who they blamed, probably the last engineer. The crap usually rolls downhill. Stupid reports from ATF and fire dept. fail to explain how fire got out of control.

If you put a magic "red tag" on the shut valve it's all good!

At 0:11. If firm’s operations management turns off sprinklers before arrival of the fire brigade, might as well not call them. They will find a fire beyond their ability to intervene. This facility, or another just like it, went from pride of FM Global’s fire protection engineering prowess to a heap of burned rubble due to someone thinking they knew better. If there’s smoke, leave the valves ON.

I worked at FM for nearly 9 years as both a field consultant and account exec for engineering, and one of the most rewarding experiences was going to the Research Campus to witness testing. As part of our early training, they even sent us to the FM Global Fire-brigade training school, where our customers in very heavy industry/chemical, often in rural areas, could send their own fire brigade teams to learn how to fight specific industrial fires. One of my coolest experiences ever!! I would be interested for this side-by-side test, what commodity was tested, ceiling height (the moveable ceiling is adjustable up to 65ft), sprinkler K factor, and design (GPM/Sprinkler x Sprinklers used.(

Excellent video. Very informative!

Great insights ! Thanks for sharing valuable experiences.

when we mean lithium ion battery fire, we mean THERMAL RUNAWAY (TRA). this is NOT a THERMAL RUNAWAY TRIGGERED FIRE!!!

Notice how the smoke is rising freely and directly upwards. This is thanks to a generous and well ventilated building. That smoke can be combustible gas products and/or highly toxic smoke. Hardly what you would want in anything but an ideal situation like a dedicated structure remote from other structures, certainly not bolted to the side of a home.

Brand new to the industry. I am a Sprinkler System Designer and found your videos very informative!

I was convinced! It's a very nice video! After searching for a long time, I finally found the video I wanted. It can be seen from this that at least people's safety can be guaranteed. Because what I was worried about was that once it caught fire, it would be like fireworks and all disappear in a short period, but from this experiment, it seems that is not the case. Once fuel vehicles (ICE) are severely damaged, they can quickly burn or even explode. Looking at the burning speed of LFPO, we can see that it is much safer than ordinary fuel vehicles and lithium batteries. So I guess, if you don’t use high temperatures to get close to the LFP battery, but rely solely on physical impact and short-circuit testing, I think it should be difficult for LFPO to spontaneously ignite. Please correct me if I'm wrong. 🙏

Plumber here, thank you.

The problem is when these vent and build up a high volume of gas inside of a close space at some point something ignites the gas. If you have a vent to keep the gas from building up, they are safe even if cell melts down. I would not operate one inside my home mounted outside is safe.

Can you help me we have starting trouble in same Clarke engine

How is this indicative of fire hazard of Lithium Iron? They used a huge propane torch to cook off the batteries. If your facility is ON FIRE already, you have OTHER problems. A USEFUL test would have been extreme condition testing, hot summer day, fastest possible discharge. There should be NO danger in charge cycle as there should be fan cooling and or temperature sensors throughout stack to turn off charging and sound alarm.

awesome

Excellent presentation thank you

Thank you for stating that these should be stored outside and away from the building. This video was very informative. We are seeing more and more of these plastic and single wall metal transportation IBC's at fixed facilities for use and storage of flammable and combustible liquids without a UL listing. The concern is the storage of flammable liquids with low flash points. In transportation, the metal IBC's are inspected every 5 years. Once they get to a fixed facility, they are no longer inspected. Then there is the question about bonding and grounding of the plastic IBC's for transfer of flammable liquids. I have not seen the last IBC you show with the double wall containment and top filling and dispensing.

Lithium-ion 20 Ah -> how many Wh - or at what voltage??

Would be interesting to visit for some knowledge into safety for industrial purpose.

Wow did pretty good.

Hi i am verry proud of the people and my dad for taking part in the video

thank u,, buddy

Is the pressure from the air portion contributed by the weight of the lid separating the wet and dry interface?

LFP batteries are safe if they are protected from short circuits. You can drill through the battery and nothing dramatic will happen But what this battery doesn't like is being heated to over 300°C from the outside Then the plastic of the cables burns.

No different from the commodity materials going up in flames. Try this on fully charged batteries and not discharged batteries and see.

Great video ❤

Muito obrigado Denny! Thank you very much! Hugs from Brazil!

Pls tell me any single accident happened ie fire occured due to static electricity through out the world with authentic proof specially area where temperature does not decrease below 10 degree centigrade in winter...any single example of fire incident??????

Price list pls all parts of fire splinkler

Thank you. the problem is very serious. fires at OZON warehouses in Russia and Walmart in America confirm this.

FALTO MAS PRESION DE AGUA , SE VE QUE NO LLEGA BUENA CANTIDAD DE AGUA AL FUEGO

This is not a lithium battery thermal runaway fire. This is a packaging fire. Try again.

Can we download this video to share with operation team ?

Great video! Really well detailed and easy to understand the facility.

At least it didn't do the flamethrower thing, or spewed burning droplets everywhere.

Before I retired the company would have what they called a Worldwide Conference at the Boca Raton Resort and Club, (a Waldorf Astoria Resort). I'm not sure of the business purpose, but there was a lot of good food and drink for several days, and some activities. I went on the group bicycle tour. There were speakers, the best of which I recall the astronaut/air force officer/M.D. who related a precarious situation on a space station and some lady who climbed Mt. Everest on her second attempt. There was also a street artist and a pair of jugglers/comedians. These were insteresting people interspersed with boring FM managers who sounded like Charlie Brown's teacher to my mind. These "conferences" were pre-pandemic and attended by employees from all over the world. I'm sure it cost the company an astronomical fortune. There wasn't any work or real training to do, so it was almost fun within the tightly circumscribed world of work.

I remember Data Sheet 8-9 that had flowcharts that referred to flowcharts that referred to other flowcharts. I thought they should have developed apps to handle that for you. I also remember a training class on the major revision to 8-9 roughly ten years ago where they admitted there was a fair amount of guesstimate involved in the old standard. I'm not sure which was worse, DS 8-9 or the windstorm crap. I'm just so glad I'm retired and don't have to care about it anymore.

It was a pretty good company to work for, but I am so very glad I was able to retire early. I no longer worry about complaint emails, tedious report writing and long boring meetings and training that could have been handled with an email. An awful lot of fat could be trimmed from management ranks, but still they muddle through generally with pretty good results despite them.

Oh, I have fond memories of goldbricking at FM.

I believe I released too much air during the monthly drain down or not fully turn off the water valve; I don’t know so I got a red light in my fire panel. Can you explain what triggered the panel light ? Was it the accelerator pushing the clapper up ( but after opening it chambers the clapper was close) or the air pressure switch.

rollpaper or rolls of polystyrene foam rolls as they are stacked like this. least at genpak.

Excelente Video

ohhhh so this is why storage systems sometimes get designed with small hose connections around the racks. The idea must be for a rack to be controlled like this and for the FD to finish it up with a 1 1/2" connection. But still most FDs would probably just go in with a line from the pumper.
