These engineers combine science and detective workBIZ SPOTLIGHT – Engineering
Most engineers are in the business of making things; Roger Boyell usually takes them apart. For the last 30 years he has used his training as an electrical engineer to help resolve lawsuits as a forensic engineer. A member of the National Academy of Forensic Engineers and a licensed engineer and private investigator in New Jersey, Boyell has consulted or given testimony in hundreds of cases. The Moorestown-based expert spoke about his investigations into mechanical failures and other incidents involving devices from power strips to scooters with NJBIZ Staff Writer Thomas Gaudio.
NJBIZ: What is a forensic engineer?
Boyell: First, an engineer is a worker who applies the knowledge and techniques of mathematics and science to real-world problems.
A forensic engineer can be from any specialtyÂelectrical, mechanical, civil, chemicalÂbut he devotes his activities to resolving matters in contention in the legal forum. The forensic engineer is trained and has experience in diagnosing what happens after the fact.
NJBIZ: What is a typical case?
Boyell: Several times lately IÂve had occasion to investigate electric shock in industrial settings. [One case involved] a manufacturer that was making some high-voltage equipment. In the course of making the equipment they have test procedures that an operator is supposed to go through to test it. There was a very earnest operator who was moving ahead with his test.
Unfortunately, he was working alone and was doing something not expected of him and he got his hand across high voltage and killed himself.
The questions were then asked: How did it happen? And, of course, who was responsible?
NJBIZ: What role did you play in that case?
Boyell: My job was to explain to the jury how it happened. The lawyerÂs job was to take my analysis and ascribe the fault.
What I found was that the employer did not recognize the hazard he created for the employee and the employee did not recognize the hazard because he was working around high voltage all the time.
NJBIZ: Who hired you?
Boyell: It was the plaintiff, the estate of the deceased worker.
NJBIZ: Are your hired mostly by the plaintiff or the defense?
Boyell: IÂm about 50-50. Some medical experts typically are retained by only one side or the other. I try to work all sides. I claim that the evidence tells the tale. Whom IÂm working for should not make a difference. Now, itÂs hard to not get personally involved with a case. You begin to either sympathize or nonsympathize with one party or another. ItÂs hard to remain detached. Since youÂre hired by one side, frequently you must recognize that the continuation of your job depends on your finding in favor of that side.
NJBIZ: Then do you feel pressure to find evidence that favors your client?
Boyell: No, but if you find that the side youÂre working for is not going to benefit from your testimony, youÂve got to tell the clientÂusually the attorneyÂthat ÂIÂm sorry but my opinion is this and hereÂs why.Â And in some cases, the attorney will say, ÂGee, thank you very much, IÂll go elsewhere.Â But usually with things in the physical world, there are objective tests [that will result in the same findings].
NJBIZ: Tests like what?
Boyell: In the case I mentioned, what was the voltage that the worker was exposed to? Well, you can go measure it. ItÂs not a matter of opinion but of measurement. You know that 120 volts from the wall outlet is pretty dangerous. So if he got shocked by 600 volts, thatÂs five times that number.
NJBIZ: Do most of the cases youÂre hired for go to trial?
Boyell: No, most donÂt. They get resolved partly, I hope, as a result of my analysis and partly because itÂs just easier to settle than go to court. There was a case for example, in which a worker had his hands cut off by a machine.
We found an electrical defect in the machine that may have contributed to it and there was a sizable settlement by an employer or an insurance company without the need for trial simply because we found an electrical defect for which one of the parties would have been held responsible had it gone to court. ItÂs nice if things do settle and everybodyÂs happy.
NJBIZ: In the case of, say, a possible mechanical flaw, do you examine the equipment that failed and take it apart?
Boyell: Exactly. You go to the site, examine the equipment, take it apart, try to replicate the circumstances as much as possible. If itÂs an equipment failure, first of all you tell the people to preserve the equipment in the shape that itÂs in: DonÂt use it, donÂt touch it, donÂt modify it. Frequently then an examination in which you replicate the circumstance will reveal the flaw.
NJBIZ: How do you replicate the circumstances at the time of the incident?
Boyell: In the case of machinery or automatic doors or vehicles, you try to put them through the same operational steps that occurred at the time of the incident. For example, there was a battery-operated scooter-like device that a rider was using and he got thrown off. I was asked to determine how it occurred. What I found was a defect in the device that was, I believe, the manufacturerÂs error that has since been corrected. I was able to do it by simply replicating the riding of the scooter in the manner that the claimant did until the defect occurred. It was fun!
NJBIZ: Were you thrown from the scooter?
Boyell: No. I was very careful. It did indeed fail, but I was prepared for the failure.
NJBIZ: How have the trends in the types of cases youÂve worked on changed?
Boyell: Twenty years ago there were a lot of cases involving traffic radarÂpeople disputing the validity of traffic radar, frequently for good reason. Five or 10 years ago, the big thing was mobile phone site selection: Why do we need to have an antenna here? Why canÂt it be in someone elseÂs backyard?
The current big rash of cases seems to be fires of apparent electric origin, typically from power strips, whether from their abuse or improperly designed power strips.
When you buy a cheap, plastic surge suppressor power strip, youÂre buying a potential hazard.
