NFPA 921 Guide to Fire and Explosion Investigation
Whether you’re a fire marshal or insurance adjustor or an investigator from NIST; the NFPA 921 Guide to Fire and Explosion Investigation sets the bar for scientific-based investigation and analysis of fire and explosion incidents. Referenced in the field, in training, and in court, it is the foremost guide for rendering accurate opinions as to incident origin, cause, responsibility, and prevention. It is intended for use by both public sector employees who are responsible for fire investigation and private sector professionals who conduct investigations for insurance companies or litigation purposes.
Fire and Explosions
Most fires have explosions. Explosions are fire, a rapidly expanding fire. Stores of volatile materials, fuel and gas lines and storage tanks, electrical junctions, and dust can all explode at high temperatures. When NIST investigated the fires and collapses of the three WTC buildings, the NFPA 921 Guide should have formed the base of the investigation. Therefore NIST should have investigated for fire and explosions, not one or the other or just fire. It was capricious, unprofessional, and unscientific for the NIST investigators to omit explosions from their investigation.
NIST claims that there was no evidence to suggest they investigate for explosions but that is a tricky lie. A lie that many debunkers and those ignorant of the reality of fires and explosions love to parrot. Claims that there need to be witnesses testifying they heard explosions is just plain nonsense. Here’s what the NFPA 921 Guide has to say;
21.1.4 Although an explosion is almost always accompanied by the production of a loud noise, the noise itself is not an essential element in the definition of an explosion. The generation and violent escape of gases are the primary criteria of an explosion.
How are investigators to know if there was a violent escape of gases? Well, structural damage is a clue. Regarding structural damage from an explosion, the NFPA 921 Guide breaks the damage into two categories, high order and low order;
21.3.1 LowOrder Damage. Loworder damage is characterized by walls bulged out or laid down, virtually intact, next to the structure. Roofs may be lifted slightly and returned to their approximate original position. Windows may be dislodged, sometimes without glass being broken. Debris produced is generally large and is thrown short distances. Loworder damage is produced by slow rates of pressure rise.
21.3.2* HighOrder Damage. Highorder damage is characterized by shattering of the structure, producing small, pulverized debris. Walls, roofs, and structural members are splintered or shattered, with the building completely demolished. Debris is thrown great distances, possibly hundreds of feet. Highorder damage is the result of rapid rates of pressure rise.
I would say that all three WTC towers that collapsed had HighOrder Damage. According to the foremost scientific experts regarding fire and explosion investigation; that HighOrder Damage was likely caused by an explosion. I did not say explosives. I said explosion. The fact that the NIST’s site has a page or ten regarding nano-thermite and why it did not investigate for nano-thermite is a silly tangent; it doesn’t matter. NIST should have investigated for explosions which it did not; there was no need to focus on one possible cause, a high-tech military grade incendiary. Just explosions, which can have many and varied causes.
Thank you. It isn’t that I don’t like videos I am just not interested in proving people heard explosions. Of course they did. As a New Yorker who watched the Towers fall from the street. I’m more than aware of explosions. Though it’s anecdotal, hearsay, here’s my experience with explosions on 9/11.
After the Towers fell. After I called my family to say I was okay. After I’d watched enough news. Around 2:30 or 3:00 in the afternoon a friend called and told me to come over and I accepted. He had just moved to a great building that had had a view of the WTC a safe distance away. Of course by then it was a view of a southeasterly arcing column of smoke shrouded in dust. Anyway it wasn’t a long walk, about the only mode of transport, and I arrived at his place around 4:pm. My walk over was surreal. The city was quiet but the sidewalks and bridges were fairly crowded with folks. Everyone was calm and somber no one was hysterical, not even folks so covered in dust they looked like statues, as a New Yorker I wasn’t surprised by my fellows but it was impressive. When I got to my friend’s place all that changed. As I entered his new building’s spacious modern lobby, I was shocked to hear a woman screaming hysterically at the concierge. Here’s what she was screaming.
What is wrong with everybody? Why is everyone so calm? My husband’s a cop and he’s been down there all day. He says there are bombs everywhere. He says things have been blowing up all day. He’s certain this isn’t over yet. He says it’s just the start.
The concierge was noticeably uncomfortable but letting her vent. I was freaked out a bit because she wasn’t crazy but scared. And then my friend came out of the elevator. He walked up to the woman and he embraced her and she started sobbing. He waved me over and he introduced me to his sister. We three went up to his apartment and his sister was given a drink settled a bit. And more calmly she explained that her husband was a cop. He had been at WTC since before the planes hit responding to possible explosions in the building. That she hadn’t heard from him until afternoon we he called and told her to go to her brother’s place where he’d pick her up when he got off duty. And then she started on again about her husband saying there were bombs everywhere going off all day. We turned on the TV and watched in silence. Ordered food. Then near midnight her husband and another cop showed up, friend or partner not sure, but they’d been at and around WTC all day. What they told us.
- That they were called to WTC before the planes hit because someone called about an explosion. That when they arrived the entire lobby (they didn’t say or I don’t remember if it was the North or South Tower) but the lobby was destroyed. All the windows shattered.
- They initially thought the lobby had been bombed but were told that the explosion occurred in the basement levels. By that time FDNY had arrived so they didn’t go down but the firefighters said it was chaos in the basement and injured and dead folk.
- They said that they began to turn people away from entering the building and pushing those coming out to leave immediately.
- When the first plane hit they said it was like nothing they’d ever heard. A bang and a reverberation down the building.
- They then moved to getting people away from the buildings. And at this time they started hearing smaller explosions.
- By the time the first tower fell they had the are cleared for at least a block from WTC. They said that when the building started coming down they stopped being New York’s finest and like everyone else just ran for their lives. Within a minute they were engulfed in dust and were essentially blind as they continued to run.
- It wasn’t til they were ten blocks away that they could start to see but the air was still thick with dust.
- Resuming their roles as cops and herding people away they kept getting the shit scared out of them by explosions that seemed to come from everywhere.
- They were at a safer distance when the second tower came down but everyone still ran.
- For a couple hours after they continued hearing explosions. And that’s when he called his wife to go to her brother’s place.
Since these guys hadn’t seen the news we went back to watching the TV while they ate. They were interested to see the Pentagon and were confused how different the situation was from WTC. They couldn’t believe that there wasn’t more destruction. We hung out and watched the news til almost dawn. The entire time we watched the news they kept anticipating a report on the explosions. There were none. They insisted we watch something local because they figured there’d have to be something about the bombs. Of course there wasn’t. I kind of hate to admit it now but I started thinking these guys were obsessed. Their whole story centered on bombs and explosions and there was no mention, or little we saw regarding explosions. I began to think that their narrow escape from the first tower shell shocked them to thinking they heard explosions. Of course now in hindsight they weren’t rookies. They’d been around and they’d been at Ground Zero for 16 hours and their agitation about the news saying nothing about the explosions actually reinforces their claims.
Like I said it’s anecdotal and it’s hearsay, but 9/11 was about explosions from that day, 17 years ago tomorrow, and today makes more sense than ever. And that’s all I got on the topic. Cheers.
When Scott Schrimpe of the FDNY said he broke off solidified molten steel off the World Trade Center box columns, he could only assume it was jet fuel because that is what he was told it could be.
columns looking like "debunked" clean up columns
Well, aside from the fact that nothing he says is reasonable, I guess he saw what he saw.
Metal melts when it gets hot. Hell, last night I threw a beer can into the fire and the aluminum didn’t just melt, it actually burned and turned to ash.
(WTC box core column is not a beer can, those core columns can't be melted period by normal means. )
(WTC box core column is not a beer can, those core columns can't be melted period by normal means. )
So forgive me if some molten metal in the middle of a massive fire doesn’t really get my spidey senses tingling….( Clearly Scott Schrimpe assumed "jet fuel" because no "middle of a massive fire" existed. The Location was 6 floors below in the basement he found molten steel. ..
Explosives need to be said. file a Writ of Mandamus on 9/11 explosives

Those 62% were blown all over city, 3,000 feet in all directions in some cases. So 62% were NOT killed by any other means but explosives. So the murder weapon was explosives and only explosives.

So what normally happens is "Moderators" just deleted everything. A good example below.
Mr. Fletcher’s graph is quite telling. Ignore the irrelevant noodles (copper, cast iron) and look at the green line (structural steel)
At 250 C (the maximum temperature reported in NIST’s findings for core steel) structural steel is actually at 135% of its room temperature strength! Mr. Fletcher’s evidence is that the fire did not weaken the steel — in fact it strengthened it by 35%!
Answer is Jet Fuel can’t do anything.
- Scott Schrimpe has a Molten Sample and its on display.
2. GEB Guide Dog Salty and Omar Rivera: reported a synchronized series of explosions immediately prior to the collapse.
- Brent Blanchard Implosion World 9/11 quote
- 9/11 events "Relates more to military explosive demolition than to building implosions, which specifically involve the placement of charges at key points within a structure to precipitate the failure of steel or concrete supports within their own footprint. The other primary difference between these two types of operations is that implosions are universally conducted with the utmost concern for adjacent properties and human safety---elements that were horrifically absent from this event."
All the questions have been answered by people on the ground.
The truth movement did an absolute terrible job. Firefighter’s were displaying their molten examples on display tables and not a single “Truther” knows anything about it. If the Truth people didn’t know, then what about the rest of world? Answer is zero people know anything about 9/11.. They did a bad job (9/11 Truth) then and they are doing just as badly a job today.
“ no theory that states jet fuel melted steel anything “ This is true. BUT the evidence collected by firefighters, displays at museums and video recordings ALL state this did happen.
So that is were The sarcastic theory of “Can Jet Fuel Melt Steel beams” The answer is NO and then the issue is why does all the evidence point in the direction and how to avoids the tough issues.
The question then becomes: Why does everyone not get the sarcasm? The reason is because the evidence does fit any theory but the 9/11 Truth Movement theory and if you can't agree with that you must begin deny what is plan to eye.
