Testing…testing… Is this thing on?

Many people just take for granted that something is just going to work, and in many cases assume that it will work forever.  One such device that does not get enough attention is the Ground Fault Circuit Interrupter (GFCI).   Simply put, a GFCI is a protective device that compares the current flowing on the hot and neutral wires of the circuit and will “trip” to disconnect power to the circuit if a small imbalance of current is detected.  The imbalance of current is an indication of a dangerous alternate path for the current to flow from a damaged line cord or a fault inside an appliance and constitutes a shock hazard to a person.

Ready, Set, Fly! – Understanding Another Technology for Forensic Investigations

Author

This is the first blog in a series on integrating new technologies into the process of forensic investigations.  Documenting the scene of an incident accurately, efficiently, and safely is a key step in every investigation.  Busy roadways and unstable structures present hazards to the investigator during the investigation process. The use of remote sensors can reduce these risks and provide data that otherwise could not safely be obtained. Read More

Chemical Engineers: More than Glorified Plumbers – Really!

As a senior at Virginia Tech, I was told that ChemE’s were little more than glorified plumbers.  Looking back, I’m pretty sure it was to keep our geek-egos in check. It was an effective tool! However, as I grew and traveled as a professional, it became an effective descriptor; applying to a larger scale and using a modifier or two for specific applications.  So, if you have a loss that falls into one of the categories below, a ChemE could be the expert you need.

New 2017 Edition of NFPA 921 Guide for Fire and Explosion Investigations

Author

Over the course of its 25-year history, NFPA 921 Guide for Fire and Explosion Investigations has changed the practice of fire investigation for the better.  Without a doubt, NFPA 921 has appropriately driven a more rigorous approach to fire investigation that seeks to avoid cognitive bias and reliance on techniques that, when rigorously examined, are little more than pseudoscience.  One need look no further than the Cameron Todd Willingham matter, wherein a Texas man was executed in part based on a flawed fire investigation, to understand the importance of conducting a proper fire investigation.

As the weather turns cold, many people use fireplaces to provide supplemental heat. The warmth from a fireplace is a comfort and the aesthetics of a glowing fire are a pleasure.  However, there is nothing pleasurable about a residential house fire that results from an improperly built or used fireplace or chimney.

Structural Evaluation After a Fire – Post-Fire Tips for an Insurance Adjuster, Part I

Author

This is a 3-Part series to help insurance adjusters during a claim inspection make a post-fire assessment of a building’s structural framing system.  From my numerous case history inspections involving damage to structural framing members after a fire, what appears obvious and straightforward is not always the case.  This article is a quick synopsis to help the adjuster be better prepared for a structural inspection and assessment while understanding what needs to be looked at, and if there are hidden factors to further investigate.

Fire Losses Involving Improper Construction and Installation of Fireplaces and Chimneys

On a cold winters night a family is gathered in the living room of their home enjoying the warmth of their fireplace.  After using the fireplace all day, they go off to bed to a nice restful sleep.  However, they are soon rudely waked by the sound of a smoke alarm in the home.  Rushing out into the cold night they can see smoke, but no flame in the home.  Outside, they can see that the chase around the fireplace chimney is burning.  The fire department is called and thankfully extinguishes the fire before it does widespread damage, however the family must leave the home for several months as repairs are made.

A portable electric generator should never be operated indoors, including garages, crawlspaces and sheds.

Winter Safety Tips for Portable Electric Generators

During winter ice storms, power to residences is often lost and homeowners revert to using gasoline powered portable electric generators.  It is often thought by some homeowners that leaving a generator outside in the severe weather may damage it or affect its performance and therefore resort to bringing the unit inside the shelter, typically, the garage. This is particularly hazardous when the generator is run for an extended period of time as carbon monoxide (CO) poisoning from the toxic exhaust gas can cause death. In addition, other hazards including electric shock, electrocution, fire and burns potentially can occur. Read More

Product Design is Critical to Consumer Safety

As the holiday season nears, thoughts turn to wonderful home cooked meals with family.  Few things in life are more pleasurable than a traditional holiday turkey feast. Yet for an unfortunate few, holiday meal time can turn tragic if a turkey frying accident occurs.   While fried turkeys may be tasty, many fire safety experts feel that the reward is not worth the risk.  In fact, UL will not list a turkey fryer, even though a product safety standard, ANSI Z21.89 Outdoor Cooking Specialty Gas Appliances covers the product.  Additionally, the National Fire Protection Association discourages their use.  Links to these organizations’ statements on turkey fryers are included at the end of this blog. Consulting those links and watching a few online videos of a turkey fryer catching fire can be insightful, and a bit sobering, if you are thinking of frying a turkey.  Read More

Explosion Investigations Uncover Answers

Author

The cause of an explosion can result from a chain of events in some cases. In many residential explosions and resulting fires, the facts can point to a number of potential causes. Certified fire and explosion investigators, like Warren engineers and technicians, have the experience and training to uncover and evaluate scenarios with high degrees of certainty. In some cases, like one residential explosion I investigated, the chain of events can start days before the loss.
