Does NIST not testing for explosives and not testing WTC7 steel invalidate everything

[Cairenn]

Sorry, jomper, Jazzy has facts, figures and physics to back him up, you have theory that ignores the facts.

 

[Josh Heuer]

YOU falsify it, then. Go create yourself a civil engineering structural simulation to prove NIST wrong.

It would be funny if you tried. I'd like you to try. Go on, please.

Oh, you appeared to overlook the rest of what I wrote, so I will repeat it, because I would like you to respond to it.

New York firemen said the building was damaged, sagging, and on the way to collapse.

What were their motives for saying that?

Had they been prepped with that story, even though they had just seen six hundred of their comrades deliberately killed by the people prepping them?

I still have a hard time understanding why people keep using eyewitness accounts only when it fits their story. First off, that's borderline conspiracy (when a CT uses eyewitness accounts it's only because 'it fits their preconceived notions etc' but when a debunker uses eyewitness accounts it's ok because it fits the narrative of what they think happened? 'Scuse that last part, I meant 'official story').
Second of all, who said anything about firemen being prepped? You're just suggesting conspiracies at this point, and further derailing the topic of conversation, which is about NIST not testing for explosives.

 

[Cairenn]

We have discussed the reason they didn't test, many times. If you have someone that was shot in the head in a robbery, the ME doesn't run extensive toxicology tests. The cause of death is KNOWN.

Y'all nitpick the any of the reports by the NIST or other experts, and yet I have failed to see an explanation or how or when or who could have set up a controlled demolition.

Also, they did have folks from one of the Controlled demolition companies looking at and photographing the debris. They didn't see anything that would say that it was demoed


http://www.implosionworld.com/Article-WTC STUDY 8-06 w clarif as of 9-8-06 .pdf

In the weeks following 9/11, several Protec building inspectors and staff
photographers, including this author, were contracted by demolition teams to
document the deconstruction and debris removal processes at Ground Zero.
These processes included the mechanical pull-down of the remains of the U.S.
Customs Building (WTC 6) and various other activities occurring simultaneously
throughout the site. Our teams took thousands of photographs and personally
examined untold amounts of debris, includi
ng countless structural elements from
WTC 1 and 2. While these photographs and video recordings were not originally
intended to specifically prove or disprove
evidence of explosive demolition, they
do provide substantial visual evidence that relates directly to this analysis and
place us in a position to speak first-hand of conditions on site rather than relying
on outside testimony or hearsay.

Here is more evidence of buildings 'pancaking'. These didn't even need a fire.

On January 25, 1971, two thirds of a 16-story apartment building collapsed while under construction at 2000 Commonwealth Avenue, Boston, MA. Four workers died after a failure on the roof instigated a domino-like collapse all the way to the basement, where the men were found. Fortunately, the collapse took a long enough time for most of the workers to run to safety.
...
After the roof collapsed, the roof settled and most of the stranded workers could be rescued using the crane and construction elevator. However, about twenty minutes after the roof failed, the east side of the structure began to collapse. A resident of 1959 Commonwealth Ave. described the collapse as a domino effect (or progressive collapse). The weight of the collapsed roof caused the sixteenth floor to collapse onto the fifteenth floor, which then collapsed on the fourteenth floor, and so on to the ground (Litle 1972). At first the different floors were distinguishable, but later dust and debris made it difficult to discriminate between the various floors.

http://matdl.org/failurecases/Building_Collapse_Cases/Bailey_Crossroad

On March 2, 1973, the Skyline Plaza apartment building in Bailey's Crossroads, Virginia collapsed while under construction. The collapse extended vertically through the building from the 24th floor to the ground, leaving an appearance of the structure as two different high rise buildings with a gap between them. The collapse tore a sixty-foot (18 m) wide gap through the building all the way to the ground. At the time of the collapse, two practically identical reinforced concrete towers had already been built (Kaminetzky 1991, p. 64)

Hey, don't look at me. I never suggested it was a controlled demolition.
I'm once again simply suggesting that the thread topic is being derailed. Pancaked buildings? How does that tie in with the WTCs being/not being controlled demolitions or NIST not testing for such?

 

[Cairenn]

I offer the pancaked buildings for those that feel that the buildings should have fallen over.

I ask you this, Do you expect the ME to do a toxicology report on someone that died from a gunshot in a robbery?

The testing was not done, because all the steel had been mixed up. Real life is not a TV script. What we see on CSI and such shows is romanticized , cases are not solved all that neat and quickly. All the needed evidence may not be available.

 

[Ron J]

WTC7 falling like a controlled demolition due to fire is what has astronomical odds against it.

To fall as a controlled demolition, all the components of a controlled demolition must be present. WTC7 did not have all the components of a controlled demolition. The building did have all the components of an out of control fire.

 

[Ron J]

Debunked ;-)



and right about 25 seconds into this one we see what should have happened in the world trade centers where the tops of the buildings should have slid off to one side or another

The top of WTC2 did tip to the east as it began to collapse. However, it was still connected to the rest of the building as it began to collapse and began to tip back to some degree.

The top 15 floors of WTC1 collapsed straight down upon the remaining 95. What should and did happen was related to the manner of structural failure in each Tower, which was different, due to the manner in which each plane had struck each Tower and the pattern of the spread of fire.

So you're saying that because a toxicology report doesn't necessarily have to be done on someone who died from a gunshot wound, that means no agency should have inspected the 9/11 site for explosives?

I see that you're trying to make the point that they (whoever was in charge of making this decision) basically KNEW what happened and therefore didn't need to test for explosives.

 

[MikeC]

No - he's saying that there's no need to test for explosives because there's no evidence that explosives were used, and plenty of evidence for structural collapse after fires.

 

[Cairenn]

If you are trying to determine the cause of a death, you start by looking at the obvious--a gun shot wound, found in a river, etc. Let's take the body found in a river. Did they drown? Why were they found in a river? Where they fishing/boating? Did anyone see then jump of something? and on and on. You eliminate the obvious first. You don't start off testing them for say Sarin.

That is the way any investigation works for the cause of a death or an accident.

 

[Jazzy]

First off, that's borderline conspiracy (when a CT uses eyewitness accounts it's only because 'it fits their preconceived notions etc' but when a debunker uses eyewitness accounts it's ok because it fits the narrative of what they think happened?

No. I think you're missing the point.

Eyewitness reports are notoriously unreliable because they aren't normally professional observers observing events in the course of their profession. The firemen's eyewitness observations were far less unreliable. They were using their professional expertise and experience to observe the condition of WTC7.

In this event, it is true that everyone there thought they were still under attack even after the formative events had already been carried out (the two planes hit the towers), because there was no indication otherwise.

It is also true that during those hours of horror, confusion, and alarm, large fire-induced or fall-induced explosive events were likely to be interpreted as developments of an attack rather than consequences of the fires.

But by the time WTC7 collapsed, the fireman had already concluded around three hours previously that it was going to do so.

So when you choose to ignore what they said, you are declaring that either a) they were unreliable (as if they were average "Joes") or b) they were lying.

Well they weren't average eyewitnesses, were they? And if they were lying, then they must have been doing so on the orders from someone who had just murdered six hundred of their comrades. That doesn't seem very likely, does it?

On the evidence of the many fireman (you know, people who have spent their working lives dealing with buildings being destroyed by fire) it also seems pretty reasonable not to bother checking for explosives in such an event. Especially when there were so many other more urgent tasks to carry out.

If large damaged steel buildings go out of shape, sagging or bulging, with a large fire burning within them with no signs of running out of combustible material, they are going to come down. This isn't a hypothesis. It's a certainty, with maths and physics behind it. It's calculable, and of course it was computer-simulated. The technique used is a normal engineering practice these days. I wish I had had access to it during my career, but during that time it was only used in mainframe computing, to which I had no access.

I ask you this, Do you expect the ME to do a toxicology report on someone that died from a gunshot in a robbery?.

I expect a coroner to base his findings on an examination of the body of evidence. Without a body of evidence to examine, cause can't be legally determined. To wade through the soup of analogies with you, think of a man seen by many falling from a rooftop into a river. Certainly, the fall could have killed him. Certainly, many people saw him falling. Certainly, when the fall was over, he was dead. How is it safe to assume the fall was what killed him, or that he jumped himself, before the body is found? If the river sweeps the body away, is it automatically a suicide?
Perhaps some effort should be made to retrieve and examine the body, so an accurate conclusion can be reached? All it would take is the will and man-power to put boats and nets in the water, right? Sure, it's sad to say it'd depend on who did the falling, but in this case it was Uncle Sam himself... so why the hell not try?

The testing was not done, because all the steel had been mixed up.

Oh... Jeez... all mixed up...? Well, shit... I mean... then we'd have to like... SORT it or something. And then like... try and determine which bit is which and stuff.... and that would take like, a year or something... maybe three. Cost like, fuck, 100-million...? Maaaaaan, that's like... a LOT of work. Fuckit, lets just spend 6 years rendering some cool CG and go to WAR, baby..!!

Real life is not a TV script. What we see on CSI and such shows is romanticized , cases are not solved all that neat and quickly. All the needed evidence may not be available.

No one's talking about Horatio Caine making inappropriate puns before solving the case with an 'enhanced' photo of Dick Cheney in the reflection on someone's eyeball holding a detonator switch. We're talking about the hard, dirty, grueling work of moving, separating, examining, cataloging, and then 'assembling' the structural steel of WTC 7, with a focus on locating and studying the catalyst of its collapse. It could have been done, there were people willing to do it who protested at not having the chance, and even after it was realized the 'mistake' of rapid destruction of evidence was being made, costly but effective measures could have been taken to locate and retrieve the steel which had already been shipped. You're right. The real world isn't a TV script, and serious questions aren't answered with stylish pant-suits and nonexistent technologies the next day. Just the same, answers by stylishly dressed men and women on the Television were offered up as truth the day after 9/11, and with repeated lines that seem a bit scripted, wouldn't you say?

 

[jomper]

On the evidence of the many fireman (you know, people who have spent their working lives dealing with buildings being destroyed by fire) it also seems pretty reasonable not to bother checking for explosives

These would be the same firemen that long ago codified a standard procedure to test for accelerants when investigating fire, right?

 

[Josh Heuer]

That is the way any investigation works for the cause of a death or an accident.

Great, except we're not talking about a death or toxicology report. We're talking about a massive, chaotic terrorist attack on multiple locations, and the subsequent investigation that followed.
Again, this was a terrorist attack. Terrorists frequently use bombs, that's FACT. We have multiple firefighters claiming they heard explosions; in the chaos of the day, this is simply passed on as being error, that these explosions were just random side effects of the office fires.
So in such a chaotic, terrorist attack, they were 100% sure no explosives were used in any way (I'm not talking controlled demolition, I'm just saying any sort of explosives) even after multiple witnesses hear explosions. How convenient, don't you think?
So much for an investigation, it seems like they had their answer from the start. Office fires and only office fires, no ifs ands or buts.

 

[Jazzy]

And I'm telling you that in this case you are absolutely wrong.

"The NYFD firemen were using their professional expertise and experience to observe the condition of WTC7."

These would be the same firemen that long ago codified a standard procedure to test for accelerants when investigating fire, right?

Yes.

They already knew what their "accelerant" was. WTC 1.

I'm glad that you now appear to accept that the firemen weren't "eyewitnesses" but "professional consultants".

 

[Cairenn]

But a bomb or even 3 or 4 of them would not have caused what we saw. It would have taken months of preparation to have set charges to implode the buildings. Those charges would have had to be hardened against the fires, and some way of setting them off at the appropriate times would have been needed. Now all the folks that set those charges would have to have been 'disappeared' or something. There would have been a Manning or a Snowden among them.

The 'explosions' that were reported were small local ones, that have been explained by things like fire extinguisher, Generator fuel and other things exploding.

There is zero evidence that explosives were used, the buildings did not fall into their own footprints, no matter how many times you try to say they did.

What is interesting is that the folks saying it was a controlled demolition will use these maps to try to prove their 'points', when what the maps show is what the experts say happen. The interior dropped and the exterior fell second and part of it fell away from the footprint.

That's a great diagram, Cairenn. Very interesting.

It's possible to distinguish the fall of the external column steelwork - which moved out at right angles to the faces of the towers in a cruciform pattern. This is consistent with ejection due to buckling.

Explosives would have moved the debris out radially from the explosion sources, and the distribution would have been circular in plan form.

But it isn't circular in plan, is it?

It's also more consistent with the exterior falling away in large panels, folding outwards.

Still at it Cairenn. Trotting out the testing for RHS.

If someone is shot or stabbed to death in the U.K, a full autopsy will be done. Protocols will be followed and everything examined. That's toxicology, liver, heart, brain, lungs condition ... everything.

Boston made it clear long ago that the steel beams are all coded so they can tell which beam it was and where it came from. I should have realised this myself but didn't. Many items are coded in this way.

 

[Mick West]

Building 7's steel was not coded.

 

[Grieves]

Building 7's steel was not coded.

Which would offer a clear method for distinguishing it from the WTC 1/2 steel, no?

 

[Cairenn]

Are you sure that they test for rare things as well? Do you have any evidence that the first set of tests include checking for say ricin poisoning or something not expected?

 

[Jazzy]

Which would offer a clear method for distinguishing it from the WTC 1/2 steel, no?

But not which floor component it was out of the forty-seven floors of WTC7, for instance. Once cleared it would be impossible to tell. The same with the columns, once they had been taken away.

I don't believe WTC2's steel reached WTC7.

It's also more consistent with the exterior falling away in large panels, folding outwards.

That IS ejection due to buckling. Different wording, same meaning.

 

[Cairenn]

It doesn't seem that they always do in the US.

An autopsy is not required in every coroner's case.
Whether or not to obtain an autopsy is probably the
hardest decision a coroner will have to make. Financial and family pressures often go against the coroner's
desire for an autopsy. The coroner should obtain an autopsy, if required, despite these pressures. ...
When the cause and manner of death cannot be established at the death scene an autopsy is required. A
death case with an obvious cause and manner of death may require an autopsy for legal documentation. In such
cases, knowledge of specific mechanics of death are desired;
e.g.
; determination of fatal wounds, contribution
of any natural disease to the cause of death and the elapsed time between the moment of fatal injury and physiological death.
...

Step 10: Record of Specimens Retained and Examinations Performed.
This phase of the autopsy will vary depending on the nature of the death and whether the case is of interest to criminal justice agencies. However,
specimens retained could include clothing, bullets or bullet fragments, and suspected gun powder residue from
the victim's skin or clothing. Toxicological specimens could include blood, urine or body tissues. Generally,
some specimens are collected for storage. This is so additional examinations or tests can be conducted at a
future date. Finally, items to include hair exemplars, fingernail scrapings, fingerprints, blood, vaginal or anal
swabs and other evidence may be collected as necessary.

For example, if the autopsy reveals a natural disease process such as leukemia or cancer, then the death would be considered natural.

The answers are not always that clear. The pathologist must consider all of the information. Severe head injuries that result in death with no evidence of assault could be hard to explain. But when that evidence is added to the police report that states the body was found next to an ice-covered, fallen ladder, the manner of death is an accident.

Yes.

They already knew what their "accelerant" was. WTC 1.

Even leaving aside the fact that there is witness testimony of explosions inside WTC 7 before the towers fell, I'm sure any reputable fire investigator would agree that what Jazzy describes here is the correct and professional way to approach an investigation.

Pictures like this certainly prove beyond reasonable doubt that every single fire in WTC 7 was definitely caused by falling debris, and wholly justify throwing fire investigation manuals out the window on this occasion.

No need for proper forensics if it happened on 9/11, is there, Jazzy?

Between Cairenn's increasingly laboured toxicology analogy and your focus on the firemen, Jazzy, my point about the geopolitical aspect and impact of NIST's failure to test for explosives seems in danger of being lost. I have no idea why you imagined bringing up the firefighters was a relevant response to this point in the first place.

As I said, your unwillingness to address the geopolitical context of NIST's failures highlights your lack of compassion for the innocent people caught up on the other side of the wars launched on the back of 9/11, as well as an inability to imagine what these people might become.

Similarly your unwillingness to address the importance of falsifiability in scientific research and your burden-shifting on this point highlights your false perspective on the demands of the scientific method in this important case.

However, if you want to continue to argue that conflicting eyewitness testimony justifies not following fire investigation protocols then, well, it's your petard to hoist: go right ahead. We can come back to the other questions later.

 

[Grieves]

But not which floor component it was out of the forty-seven floors of WTC7, for instance. Once cleared it would be impossible to tell. The same with the columns, once they had been taken away.

Difficult, costly, painstaking... but impossible? They wouldn't be trying to rebuild it using the same pieces, they'd be trying to establish which specific sections were the first to fail, and what caused that. Identifying where structural steel that failed initially was positioned within the structure would be a puzzle worthy of NIST computer models, but finding the steel which initiated the collapse and examining it/testing it would be job 1, and I don't see why that should be impossible. Surely, if the collapse was due to concentrated fire-damage on a particular support/s, those particular support/s would have endured the most obvious heat damage. If there was any explosive/chemical involvement, surely that too would be quite recognizable with a thorough physical examination.

I don't believe WTC2's steel reached WTC7.

It's almost certain WTC2 steel was touching WTC7 steel at one point, likely on a large tanker/in the smelter of a foundry in China.

Are you sure that they test for rare things as well? Do you have any evidence that the first set of tests include checking for say ricin poisoning or something not expected?

Detective walks into the Coroner's office, wanting a preview of his report. He sees to his surprise the body is still dressed.
"Er, what's the story, Doc...?" asks the detective.
"Got Shot!" barks the Coroner.
"Yeah... but how'd he die..?" asks the detective.
"Bullet, Stupid!" barks the Coroner.

 

[Cairenn]

Explosions are not the same thing as bombs or controlled demolition.

Sometimes the ideal is not possible. There was NO way to ID which steel was which. If investigating the cause had been a primary focus after 9/11, it might have possible. One would expect for WTC 7 to be lying on top of the debris from the WTC. But and that is a big but, the recovery of possible survivors and bodies were considered more important.

Would you have told the families that 'No we can't look for your family member, we have to map the site and tag every piece of steel, so we can see if someone imploded the buildings."

What evidence do you have that explosives were used? You don't like my body analogy, but it is proper and reasonable here. You don't look for an exotic cause of death when there is an obvious one.

 

[Grieves]

There was no one in building 7. If rescue efforts were the primary focus, clearing the WTC 7 site would not have been job 1. While hosts of first responders hand-dug in the rubble of towers 1 and 2 in a desperate search for survivors, a great convoy of garbage trucks was carrying massive amounts of WTC 7 rubble and steel out of the area, all evening and all night long, and every day thereafter for some time. That wasn't rescue-efforts, that was clean-up. The clean-up, especially in the case of Building 7, could certainly have waited a few days.

You don't like my body analogy, but it is proper and reasonable here. You don't look for an exotic cause of death when there is an obvious one.

The sentiment of your analogy is false. You're insisting there's absolutely no reason for NIST to test for anything 'exotic' like accelerants in the WTC 7 rubble, comparing testing for accelrants in an office fire to testing for rare poisons in a gunshot victim.... in spite of the fact it's part of the fire-code of most every developed area that accelerants be tested for in the event of a serious fire. Did NIST have the authority to choose not to follow the basic, standard procedure? Sure. But why in the world would they make that choice? "'cause why bother, it's so obvious"?

 

[jomper]

There was NO way to ID which steel was which.

Only if you support everything NIST says without question.

 

[Cairenn]

Where is that from please?

The WTC7 rubble fell on top of the debris from one of the WTC towers.

 

[jomper]

Where is that from please?

FEMA, as stated. Among other places, this was recently posted in a thread you were contributing to: The Uniqueness of the WTC7 Collapse

 

[Sticky Fingers]

That wasn't rescue-efforts, that was clean-up. The clean-up, especially in the case of Building 7, could certainly have waited a few days.

One thing you need to keep in mind Grieves, is the state of Ground Zero after the buildings came down.
It was very hard to move through. Not only because there were still some fires but because it was a big rubble pile that was very dangerous.
Point being you could only send so many people in at a time.
And considering how many first responders there are in the NY metropolitan area, well they couldn't all go in at one time.
They probably ran in shifts and put in as many as they safely could at one time.
Point being there would have been enough people to start working on debris removal without it affecting the rescue operation.
Whether they should have kept the debris or not is a different question.

 

[Cairenn]

There was a huge amount of debris and steel beams were not a high priority.

And you are still ignoring the fact that much of WTC7 was on top of debris from one of trade centers.

A flange wouldn't be useful to test for explosives, would it?

 

[Jazzy]

Even leaving aside the fact that there is witness testimony of explosions inside WTC 7 before the towers fell

Jenning's testimony I was fully aware of. Assuming it to be true makes no difference to my understanding of the effect WTC1 had on WTC7. Why he recalled explosions prior to the collapses of the towers I have no explanation for. There is too little information to come to a conclusion about. Do you possess additional information?

One thing that has always puzzled me was his stepping over bodies, when elsewhere I was assured that WTC7 had no people in it. Some of his testimony seems similar to experiences encountered in both WTC1 and 2. It's strangely inconsistent.

View attachment 3784

Pictures like this certainly prove beyond reasonable doubt that every single fire in WTC 7 was definitely caused by falling debris, and wholly justify throwing fire investigation manuals out the window on this occasion.

It rather depends on the time it was taken, was it before the collapses?

No need for proper forensics if it happened on 9/11, is there, Jazzy?

Think what you wish. I'm very forensically-minded, myself.

I have no idea why you imagined bringing up the firefighters was a relevant response to this point in the first place.

Then you still didn't absorb it. Well, keep trying.

As I said, your unwillingness to address the geopolitical context of NIST's failures highlights your lack of compassion for the innocent people caught up on the other side of the wars launched on the back of 9/11, as well as an inability to imagine what these people might become.

You did? I thought I addressed it. It isn't relevant here. I didn't launch the wars, and as you're unable to understand my point about the firemen, it would seem you'd be stretching a little too far attempting to imagine my powers of imagination.

Similarly your unwillingness to address the importance of falsifiability in scientific research and your burden-shifting on this point highlights your false perspective on the demands of the scientific method in this important case.

Falsifiability isn't always possible. Large lightweight steel buildings may be simply sabotaged in the manner of the Brighton hotel bombing. It's a problem.

However, if you want to continue to argue that conflicting eyewitness testimony justifies not following fire investigation protocols then, well, it's your petard to hoist: go right ahead. We can come back to the other questions later.

I think you have had difficulties absorbing the various timelines involved here. Keep working at it. Perhaps your reducing the levels of sarcasm and hypocrisy will help clarify your thinking.

Surely, if the collapse was due to concentrated fire-damage on a particular support/s, those particular support/s would have endured the most obvious heat damage.

Not necessarily. These lightweight steel buildings have column instability issues. The columns can be made to fail without themselves suffering fire damage. It isn't necessarily a question of support or fixings. All floors will sag with a fire beneath them, and then they will snap their fixings. If continuously welded to their walls they will pull them in, and the wall will fail in buckling. The hardest, and the most important thing to determine is the sequence of events. I'm not sure that the greatest heat damage would necessarily signify the onset of collapse.

The rest of your post was useless. Why did you bother?

 

[jomper]

Why did you bother?

Speaking for myself: I have a dim fascination with analysing the disingenuous. It's like a hobby.

 

[jomper]

It isn't relevant here.

And this is what I mean by a lack of compassion.

Why he recalled explosions prior to the collapses of the towers I have no explanation for. There is too little information to come to a conclusion about. Do you possess additional information?

I know there were reports that WTC7 started to be impacted by debris from the moment of impact on the Towers...a piece of landing gear or dead bodies flying thru a window from 60 stories up might sound like an "explosion".

regardless- what do "explosions" have to do with the the building collapsing 6 hours later?

There were a lot of reports of what people thought were "bombs" and given the context of the day its easy to see why they jumped to that conclusion. Yet, none of the explosions match up with any known method of controlled demolition- happening a random and various times in various places throughout the day. We do know there were lot of things breaking, burning, falling etc over the course of the day (falling elevators, people jumping, lots of combustibles in a fully loaded office building.

An "explosion" does not equal a "bomb".

what do "explosions" have to do with the the building collapsing 6 hours later? An "explosion" does not equal a "bomb".

In sum, explosions =/= explosives is the complete argument of why you think it was wholly unnecessary to test for the possibility and thereby ignore standard investigative procedure. Are you comfortable with that summation?

Of course, it is not the case that there were no explosions at the time of collapse, but let me ask you if I have expressed your position properly first.

If embers from a grass/forest fire set a house on fire, do you really think that they check for accelerates ? Maybe if it was one house and no one saw the fire catch, but in one of the forest fires where many houses are burned. If you have any evidence that they do, please share it.

Why do you continue to ignore the opinions of experts, like the article in "Structure Magazine"?



I had a minor explosion on my outdoor, non pro propane cooktop. I had not been good about cleaning it and grease caught fire and exploded a mostly empty bic lighter that had wandered under the burner. There are many products in our homes and in offices that will explode in a fire .
