Fire Investigation and Junk Science


Why you could find yourself a criminal suspect or civilly liable if you’re involved with a fire.

by Nick Markowitz, Jr.

Everyday there are people who are charged with arson when a fire has taken place in their home or place of business.  How many times charges are warranted is a subject being hotly debated in the fire community today.

The problem is a general lack of training for some investigators. There's even an on going debate among trained investigators as to the cause of these fires. All of this has unfortunately lead to people being arrested and eventually convicted of arson. Many are found civilly liable for causing a fire that they may not have had anything to do with. In one case a Texas man may have even been executed for the crime of arson when he may not have done it.
Now you say to yourself, “WOW! How can this happen in a modern world with DNA and advanced investigative techniques?” Well, it does, and it happens easier than you think. The worst part is trying to right a wrong in court after you've been convicted. It can take decades to be exonerated.

At any one time in this country there are various innocence-type organizations that are fighting for wrongly-convicted people. This includes not only rapists and murderers, but arsonists, too. There are excellent organizations like the IAAI (International Association of Arson Investigators) that provides standards for the training and certification of fire investigators. This includes the prestigious CFI certification. While it is not mandatory in some states to have this or any other type of certification in order to investigate fires, many states, including my own, does not even require that you be certified as  private investigator.

While fire investigators are required to follow the Guidelines of NFPA 921 on fire and explosion investigations, which bases its standards on the Scientific Method, this manual is often looked at as a guide, sometimes even scoffed at. And yet many investigators don't even own a copy.

While it is true that public sector investigators, such as fire marshals, arson investigators, etc., must be certified to do their jobs under the rules of ICC (International Code Commission), in states which follow ICC Codes many don't even know they are required to carry this certification. This includes lawyers as well.

An entire case brought by a fire marshal against an individual for arson could be thrown out of court
if he is not certified by ICC. This is due to a rule generally referred to as as “Fruit of the poison tree” where if one thing is wrong, everything is wrong. Think tree fruit and roots... yet it is allowed to go on.
Then, when it comes down to the court case, it becomes a battle of the experts and who has more initials behind his or her name as well as bravado.

Even learned experts disagree. And when you're a little guy trying to claim something happened a certain way, you can forget it. Since you are an unimportant person, you are nothing even if you are right. Because 921 or an expert says it happened this way and this way only, it's over before it begins.

A General Lack of Open Minds
There are very few open minds in learned professionals because the science tells them otherwise.
Experts as I have found do not want to listen to technical people like myself who are out in the field everyday. I have 30+ years as an electrician, a troubleshooting electrician at that. In addition I also have heavy electronics experience and I often see and observe things before they entirely burn up completely  whereas experts in many cases only know what happened afterwards.

When they investigate a claim they do not have the day-to-day dealings that a troubleshooter or someone of a lower caliber in their opinion has. So they take it off to the lab and if it can not be duplicated, then it could not have happened that way--period.

As anyone of a low caliber, as I have been called in court and fire  blogs, can tell you, when you work in the field and see something that can not be 100% duplicated in the lab, it needs recorded as it is happening in the field. This is what I have been trying to introduce into fire investigation, that sometimes statistics and instruments are not enough. Sometimes they are not accurate because of who is doing the work.

In actuality, only a relatively small percentage of fires are ever investigated. Many times if a fire is small enough, no one ever comes to investigate. The home or building owner, knowing they have a deductible, just handles it and that's the end of the story. Sometimes that damage is negligible or it's easily explained and so it's determined that an investigation is not warranted. But yet because so many of these so-called small change fires are not investigated, patterns and trends can be completely missed. Even potential serial arsonists could be at work and no one knows.

The fact is, small fires can teach us big lessons, but hardly anyone looks at them--they're written up and maybe reported on the state statistical site and that's it. This is why I have, for several years now, worked with and submitted new and different findings to investigators, engineers, and CPSC agents when I go to do my job as a troubleshooter.

Using the Scientific method along with Forensic Techniques, I carefully and thoroughly document a situation, Where I can carefully remove a burned up item I do so and I provide it to others who might be interested in examining it. How many times I have brought in a burned up electrical items and you hear an expert say, “Well, that shouldn’t have happened.”   Well, it did happen and we need to carefully document it and add hat we learn to the collective storehouse of knowledge.

I have found working as an electrician and/or fire photographer that the story I get when I go and repair something and the story an investigator gets is often two different things. When I have been at fires taking photos and I afterwords hand the disc to the fire marshal at his office the next morning and I compare notes with him, the story I get as to what someone saw and what the fire marshal was told is often times totally different. When people talk to me, they’re talking to Nick the photographer, not Nick the official who they may or may not be in trouble with.

I see this all the time as a troubleshooter. People are careful when they talk to an investigator about fires and accidents because they feel they may be blamed and their insurance will not cover it.

Case in Point
A typical matter is the one I had earlier in the spring at a customers fabricating business. The client has several 5-ton, overhead cranes they use in the facility. A couple times now I have had to go down and reset the overload system. Well this time the crane stopped for good. The owner, someone official in people’s eyes who can get them fired, walks in and wants to know whatin the sam hill caused the crane to stop working. The workers tell him, “Well boss, the cranes are old and cranky and probably just died from old age.” 

When I walk in and start working on the cranes and ask questions as Nick the electrician—a working guy just like them--I get the real story. The shop foreman mentioned to me that one of the new guys used the crane to pull a piece of steel out of the rack. I asked him whether anyone told him not to do that and the reply I got was, “No, I was not here when it took place.” I walked over to the employee and explained to him what I found, that the crane motor control blew up from abuse, not old age. I also told him that someone should have used the tow motor instead of the crane to do what they did. He told me that no one showed him how to use one and he was too embarrassed to admit it.

Well that afternoon The foreman had everyone qualify for there tow motor license and things were smoothed out because the new guy did not feel like he was being singled out for training. The boss also was happy because the problem was solved and he did not have to fire anyone as the workers handled it internally. He figured all along they where lying to him but he likes them and their good workers. So as you can see there are often two different story's and this is especially true when horseplay on a job site is involved. When this occurs, things can go very bad, very quickly.

Reflecting on Lessons Learned
My dad, a retired electrician/steel worker, and. one of his buddies from where they retired stopped by my home one day. We talked about a bad accident at a plant down river from us. His friend told us a story about something that had taken place down at the Coke Facility where he worked.

As a joke on the boss’ birthday, they took a prophylactic and blew it up to a huge size with flammable Coke Gas  and then they placed it under his office, which was couple feet off the ground on stilts. They then took a long stick with a hot poker on the end and set the prophylactic off. It naturally shook his office and when he came out all mad and ready to fire everyone, they had this huge birthday cake setup for him. It was then that he realized they where just playing a game with him.

Now lets face it, had this joke gone terribly bad, do you think any of these grown men when questioned by OSHA or a fire investigator would ever admit to what had actually taken place?  It’s for sure there would not be a trace of a prophylactic.

The fact is, poor training is just the tip of the iceberg. There are many fire investigators out there using testimony and methods which have been proven as junk science. Like spaling concrete or gator-looking marks on wood are a sure sign of a poured accelerant. But courts except it. Why? Because attorneys do not know to challenge it with a Daubert hearing to prove the theory. Once something is excepted in court, that’s it for ever. It becomes allowable testimony for a long time unless it happens to be challenged.

This is what got the gentleman in Texas executed, and now, after numerous court reviews, it has brought a rebuke of the courts for allowing bad investigation methods to be used as fact. Well, you can see what the issues are and why cases both criminal and civil can go bad.

Once I was accused of stealing from a school where I worked. Now, the detective should have done his job and found out that I am an Eagle Scout and a general stand-up kind of guy. Instead, he was a hard guy detective who was bound and determined to try and convict me for something I did not do--all because he didn’t like my answers. He  ended up tying up valuable taxpayer money, he got egg on his face, and the real criminal, a temporary cleaner, was finally caught and fired--after three months of stealing things.

Conclusion
Unfortunately too many investigators get it in their minds “this is how something went down” and “this is how it has to be.” They refuse to take two seconds to sit back and say to themselves, “Well, maybe the guy is right after all.”

Luckily the bell has gone off and some have now taken a second look. Some of them have learned that things where wrong with what they thought and they consequently stop cases in progress. Sadly, others. Continue to follow blindly and do whatever they do badly.

Everyday in this world new and completely different results are found. But when it comes to the fire investigation community, unfortunately, if you have a new look at something, it’s like the Spanish Inquisition or the questioning of Galileo concerning whether the Earth is actually flat. Now, I am sure we’ll hear from a few of these learned professionals on the subject.

This is my blog, so speak and make your point and let the readers decide. Who is believable--the guy with 30 + years to the grind stone or a “learned opinion”?

Home Sprinkler Advocate Voices Opposite Opinion

My piece on home sprinklers, published on 15 May, caused a bit of a stir among those who endorse the mandatory use of sprinklers in the home. A fire marshal based in Oregon wrote me a note and I'd like to feature it here at this time. Be sure to read my reply at the end.

Mr. Markowitz,

I was reading your Blog titled “Things they do not tell you about home fire sprinkler systems” http://nickmarkowitz.blogspot.com/2010/04/things-they-do-not-tell-you-about-home.html and felt compelled to contact you to challenge some of your assertions about fire sprinklers. My computer system at work does not allow me to post a comment directly to your blog, so I thought I’d send you an email.

I will attempt to address your comments in the order you made them;

You mentioned needed a “good” city water pressure, and while good may be a relative term, a residential fire sprinkler system can be designed for pressures as low as 7 psi. I don’t know of many, if any, municipal water supplies that can’t provided 7 psi.

Your point about connection to the water main is valid in many areas. In Oregon, multipurpose systems are allowed to be connected directly to the potable water system. In the case of multipurpose systems, there are no stagnant water issues and no backflow preventer or vacuum breaker requirements. The additional cost of systems development charges and standby fees is a problem, we are attempting to alleviate this problem in Oregon through legislation that will prevent the additional charges and fees on fire sprinkler systems in one- and two-family dwellings.

Your comments about homeowners insurance are just flat wrong and have been for some time now. Many years ago, there were some insurance companies that actually charged more when fire sprinklers were installed, but that Neanderthal way of thinking has long since passed. Every major insurance carrier in the Oregon currently offers discounts for fire sprinklers in one- and two-family dwellings. Insurance companies came to the realization that the amount of damage done by fire sprinkler systems pales in comparison to the damage done by fire, smoke and heat. Scottsdale, AZ has had a fire sprinkler ordinance in place since 1986 and their data indicates losses dues to fire in sprinklered homes averaged $1,945 compared to $17,067 in non-sprinklered homes.

Your estimates on using a well as a water source are quite a bit high, Talco offers a pump and tank package for NFPA 13D systems at a cost of $2,200. The size of the home will not double or triple the cost of the pump and tank, it may increase the size of the tank by 40 or 50 gallons, but that won’t increase the cost much. In many cases, if the well has the capacity, the system can be designed to use the well pump to supply the fire sprinklers and the well casing and recovery rate to satisfy the stored water requirements. I can design a system with flow demands as low as 16 gpm at 7 psi, which many wells can supply.

As far as cold weather and freeze mitigation goes, dry and antifreeze systems are not practical for one- and two-family dwellings for many of the reasons you state, however the standard does allow them. There are practical approaches outlined in the standard to deal with freeze problems in wet systems. While the insulation can be moved, one can make the same case for any water pipes in your home. A fire sprinkler system, installed correctly, has no higher chance of freezing than any other domestic water pipe.

With regard to maintenance, there are practically no maintenance requirements for NFPA 13D systems, and certainly no mandate in the standard to pay a fee or have a third-party inspector do an annual service on the system. Multipurpose systems that are connected to the potable water system need the same maintenance as the other water pipes in your home, which for most folks, is none.

Accidental discharge of a fire sprinkler head is around 1 in 16 million and accidental leaks of the piping are no more common than potable water piping. The story you relayed about the accidental discharge due to a microwave oven is highly suspect. The lowest temperature sprinkler head is 135 degrees Fahrenheit and I find it very hard to believe that kind of heat could escape from a microwave and make it to the ceiling level without dissipating, unless the contents inside the microwave were actually on fire. If you can provide me the actual fire report showing otherwise, I will stand corrected.

Yes, residential sprinkler heads have been recalled, so have coffee makers, laptop batteries, Toyota vehicles…….product issue arise from time to time, it doesn’t mean we abandon a sensible idea because of one recall.

The fire service has never advocated for fire sprinklers only, we have always educated people on the need for both smoke alarms and fire sprinklers as a package together, your chance of survival with both rises exponentially.

In closing, I must say that I am surprised that your blog professes to be about fire and electrical safety, yet you attempt to derail one of the most effective tools we have to guard against dying in a fire in our homes. I have to wonder if, as a master electrician, you feel the same way about GFCIs or Arc Fault protection in our homes?

---- And my reply ----

Date: Monday, May 24, 2010, 8:21 PM

Thanks for the comments.

Working [water] pressures here in my community are very low where on the tops of hills and people who have opted for systems have had to install tanks per the sprinkler installers. Maybe the installers are wrong or just selling more than needed. Part of the problem is you must be a licensed master plumber to install them in Allegheny County. That's why the [high] cost. This is also a big union area, again [it's] why the costs are so high.

The insurance thing is for real here. [I] had a customer install sprinklers 3 years ago and his premiums went up when he notified his carrier he installed them. Maybe in your part of [the] country, since you have codes in place, they behave themselves, but not here, yet. Maybe once it is state wide they will level out.

As far as microwave going off and causing the damage, I have the pictures. Remember again this was in college housing.

As far as leaks, 6 - 10 residential systems I know customers have in their homes have leaked or frozen up. It is the nature of the weather cycle around here. We're up [and] down all winter and it affects things in ways you would not believe, unless you saw it with your own eyes. We can be 3 degree in morning and 38 by lunch, then back down to zero overnight.

[Regarding] installation issues, I am constantly responding to sprinkler system issues both commercial and residential, even in the summer. I just had a big fight with Penn Hills, Pa fire depts who refused to properly respond to a sprinkler call [where] $10,000 in damage happened.

Some areas over pressure is also a big problem. Just try and find an emergency restoration clean up crew or even a sprinkler crew available here during the winter when temps drop down below zero. I have had to wait 2-3 weeks to get [a] sprinkler company rep on site because of all the damage.

You should talk to Jack Mason, CFI Fire Marshal For Penn Hills and hear all his worries over this.

I have responded to 3 systems so far this year, commercial, where single heads went off for no reason at all.

I am not derailing sprinklers, I am just stating what I know can and does go wrong with them. If we are going to promote things, let's give both sides of the issue. All I hear from sprinkler advocates are rose colored glasses. What kind of backlash do you think is going to happen around here after the sprinklers are in and start popping because of installation issues. People are going to shut them off and ignore them just like the smoke detectors they take the battery's out of because they always false.

Take Anti-lock brakes, [the] greatest thing to come out, however they have killed hundreds who did not use them right, [those who] lifted their foot off [the] pedal when they applied them because they thought something was wrong.

I am glad things are working out over there in Oregon, but your dealing with issues there which are different here. I am not saying "do not put them in," but I am saying, "let's think things through before we mandate something that's going to come back and get us."

When the first person dies in a home with a sprinkler system because we have not explained exactly why and how something works, start expecting lawsuits and TV investigations.

Counterfeit Dangers

The Fire just waiting to start in your home
Counterfeit and Knock off Electrical Items

By Nick Markowitz Jr.
Fire Investigator

You find yourself on a nice sunny spring day deciding to go for a walk what better way to enjoy it than a stop at a local Flea Market. All the great smells from food vendor's carts and the busy activity everywhere make this a special time. Unfortunately you do not realize that the choices you make this day may well result in the destruction of your home and possibly your family.

You see a vendor selling all kinds of new, cheap dollar stuff from many different boxes he has laying on plastic sheeting on the ground. You find he has some plug strips you have been needing for your computer system and kitchen, very cheaply priced at $3.00 each. Anywhere else they would cost you $12.99. And so you buy a couple of them, totally unaware that what you think is a good deal on a legitimate item is actually a dangerously-built counterfeit or look alike, also known as a Knock Off.

You go home, plug one of these power strips in your computer system and start working with your new laser printer. You get everything set up and ready to go. It's getting late and it's nearing your bedtime. You leave your computer and printer on because it also works as a fax machine. You go to bed to later awaken to the sound of your smoke detector. Your house is filling up with smoke and you instinctively get everyone up and out, just in time as flames come out of the family room where the computer is located.

Luckily tonight everyone is safe and firefighters arrive in time to stop the fire in the family room, but there's water and smoke damage everywhere.

The Fire Marshal arrives after the fire is out and he begins his investigation. He traces the fire's origin to just about where the plug strip was, but it's almost totally destroyed. Luckily, you have the duplicate strip from the kitchen to give him. On closer examination, he finds that it's not what it appears, it's counterfeit, a knockoff, made to look like a good product. Instead, it is made very cheaply.

For example, instead of a #14 gauge wire cord, it's only #16. This means that it can only carry half of the 15-Amps that the packaging says it can carry. To make matters worse, the on/off switch is also inferior because it's undersized. The unit also has no UL, FM, or any other testing agency's approval and no manufacturer's name is on it, other than "made in China."

This plug strip never should have been imported and sold in this country because it is absolutely illegal under Federal Import rules. Yet everyday illegal and dangerous items made cheaply and dangerously make it into this country. They are being sold at flea markets; dollar stores; and 2nd-hand, variety-type stores.

This is a serious problem. Just a survey of local flea markets here in the Pittsburgh area revealed 10 out of 12 vendors had illegal items for sale. All of them having been imported illegally through an importer in New York City. But when it comes to electrical items, it not just the small stuff being made, its large frame breakers and switch gear as well.

Cutler Hammer, a division of Eaton Corp., has started a campaign to make electricians aware of knockoffs. Can you imagine that the apartment or office building you may be in has illegal, copycat electrical switch gear items in it? But it happens. It even happens in the airline and automotive industries and it has caused numerous accidents and deaths. In a word, it is a growing problem.

Sometimes manufacturers will also illegally copy the UL  testing label just to make an item look legit, but it's not. The Consumer Products Safety Commission, also known as CPSC, is in charge of protecting consumers from dangerous products and they have field agents in every state. But with the rapid proliferation of illegal items coming into this country, agents are often overwhelmed and in need input from average citizens when it comes to reporting dangerous items.

When these agents come across them, which is almost weekly, the CPSC issues bulletins about all kinds of dangerous items being recalled--from children toys with lead paint issues to exploding candles, to lawnmowers with blades that break.

A recent effort by the CPSC is a down-loadable booklet which is being issued to every  2nd-hand and variety-type store in order to help them identify dangerous products that they may otherwise sell to an unsuspecting public. This helps in the removal and destruction of of illegal goods that should not be on the U.S. market.

Merchants and vendors who continue to sell these dangerous items face fines well in excess of $10,000.00. In additional these illegal items can be seized and destroyed.
The only way to stop this scourge going across America is for consumers to become educated so they can avoid these problems in the first place. As a general rule, if it sounds too good to be true, it usually is.

Winter Travelers Who Fail to Follow Common Sense

Winter Travelers failed to follow the rules when it came to travel during the great winter storm of 2010. Instead they relied on 911 to help them.

by Nick Markowitz Jr.

One of the most reliable roads one can travel in the Mid Atlantic area when winter weather is bad is the Pennsylvania Turnpike, especially when you need to get from Ohio to Philadelphia or Washington, D.C. It's well known for its famous snowplow trains--multiple plow trucks lined up like a train. These trucks are able to bust through the toughest of snow storms when winter weather gets worse than bad. However, like all roads, one must still take precautions because you're still traveling through the infamous Allegheny Mountains. With names like Tuscarawas and Blue Knob, part of the famous Appalachians Mountain chain has as many as three tunnels.

This weekend once again proved that even with the best road maintenance available things can go wrong, and they certainly did when two tractor trailers wrecked between the Donegal and Somerset exits. This brought west-bound traffic to a stop for 12 hours. The accident was bad enough that local Fire departments had to bring water and food to travelers who where unprepared. Most of them didn't bring even the most simplest of precautions, such as filling their gas tank up before they left, or a simple blanket, water, snacks, or small food items.

After all, you're traveling through mountains in the 2000 foot range and the snow and ice can be heavy in this region. Many travelers didn't even have proper winter clothing with them either, such as a heavy parka and gloves.

Today, too many people don't plan or think ahead for one minute. They automatically assume by dialing 911 that all their troubles will be taken care of. Luckily for them the first responders in the area are equipped and trained to handle the terrain, but while the turnpike travelers took up the first responders time, they had to leave their own towns unprotected while they dealt with the mess on the turnpike.

Once again a hand full of idiots put thousands at risk because they couldn't be bothered to take the simplest of precautions. There's an Old saying "Fail to Prepare, then Prepare to Fail," and everyday it's proven out by those who will not use their god-given brains to think even one step ahead.

To further illustrate my point, there where people in the turnpike mess who wore their shorts with a thin hoodie. Many of them didn't have long pants with them because, like the rest of these ill-prepared people, they thought they where only going the distance of one or two exits. They figured that the car heater would aptly keep them warm and safe. Never once did they think they could be trapped in a wreck or behind one.

As long as people keep relying on our Nanny State and they continue to think it will not happen to them, 911 will be busier than ever as idiots call whose very actions place others at risk. With things not getting any better in our society, as more and more people rely on the Nanny State, you can expect to see more and more idiotic and dumb things done by people on TV this winter.
