Abstract Forest fires are generally consciously or unconsciously the work of man for various reasons. Fires generated by voltaic arc between power lines and the underlying trees do not occur often. These few cases may be only demonstrated by analyzing around the site where the arc may have been generated. Material such as leaves, bark and soil can be analyzed to find the metallic residues from the fused cables. The electrical cables usually composed of aluminum or copper alloys, when involved in an electric arc may spray fused micro-drops of metals, increasing the natural level of such elements. In two cases, the Al and Cu concentrations were increased by between 2.56 to 13.9 times the background levels. Electron microscopy of leaf surfaces has identified some profound alterations produced by the intense heat of the electrical discharge.

In 2009-2013, U.S. fire departments responded to an estimated average of 56,000 structure fires per year in homes that involved heating equipment. These fires resulted in annual losses of 470 civilian deaths, 1,490 civilian injuries, and $1.0 billion in direct property damage. These homes included one- and two-family homes (including manufactured homes) and apartments (including townhouses and other multi-family dwellings). Space heaters are the type of equipment most often involved in home heating equipment fires, figuring in two of every five fires (40%). The fires involving space heaters accounted for 84% of the civilian deaths and 75% of civilian injuries in home fires caused by heating equipment, as well as over half (52%) of direct property damage. Another one-third (32%) of fires involved a fireplace or chimney, but these fires accounted for a much smaller share of civilian fatalities (5%) and civilian injuries (6%). Central heat and water heaters were responsible for 12% and 10% of home fires caused by heating equipment, respectively.

Automobile engine coolant related fires may result from engine coolant leakage, an increase in the concentration of the glycol in the water/glycol mixture, the nature of the vapor/particle distribution, and contact with an ignition source in the engine compartment. Ethylene glycol, a common coolant, is a flammable liquid with an ignition temperature near 800F. In recent years, propylene glycol is being used because of environmental reasons. Propylene glycol is also a flammable liquid with an ignition temperature near 700F. In an automotive application, the glycol is mixed with water at about a 50/50 ratio. Ignition of this concentration of coolant is difficult because of the water. When released at high temperatures into the atmosphere where the water evaporates, the glycol vapor/liquid droplets can reach the state of an ignitable mixture. Typical ignition sources in the engine compartment include hot surfaces (exhaust manifold, exhaust system) and electrical components (relays, distributor, spark plug wires). Automobile accidents, resulting in hot vapor expulsion from the coolant system, are also known to cause fires.

Automobile engine coolant related fires may result from engine coolant leakage,an increase in the concentration of the glycol in the water/glycol mixture, thenature of the vapor/particle distribution, and contact with an ignition source inthe engine compartment. Ethylene glycol, a common coolant, is a flammableliquid with an ignition temperature near 800F. In recent years, propylene glycolis being used because of environmental reasons. Propylene glycol is also aflammable liquid with an ignition temperature near 700F. In an automotiveapplication, the glycol is mixed with water at about a 50/50 ratio.

Abstract

In this paper, we review the research results about the identification of the electrical fire trace evidence and the fire reason recognition. We point out the existing problems and put forward the corresponding suggestions to promote the development of the cause of the fire investigation and make it better to serve for the work of fire investigation.

From Out of the Abyss...

This week’s article from the past is titled Incendiary Fires Can Be Spotted and was written by Benjamin Horton, CPCU, who was President of the National Adjuster Traing School in Louisville, Kentucky..  It is taken from the Decembe 1968 Vol. XVI No.5 issue.

Incendiary Fires Can Be Spotted 

In the new issue of NFPA Journal®, President Jim Shannon said the Association will focus on the leading causes of home fires, including cooking. "We also need to continue to push hard for home fire sprinklers. That's still a large priority for NFPA, and we plan to work very aggressively in 2014 on our residential sprinkler initiative," he said.

President's Message
Dale Feb, President CCAI 2016
From the desk of CCAI President Dale Feb

Feb

September 23, 2016

Dear Members,

September is already upon us and our next educational conference is just around the corner. I would encourage each and every one of you to attend this next exciting training program.  The Training Committee is hard at work developing an amazing program that will walk you through the process of data collection, scene investigation and report writing.  This program will include separate tracts for law enforcement and private fire investigation.  Whether you are a seasoned professional or just starting out on your career, you will greatly benefit from this program.  Please visit our website for more details www.arson.org.  I hope to see you there.

Another great benefit that we receive from the conference is the chance to visit with old friends and make new ones.  I really enjoy spending time with each and every one of you, so please take a moment to stop and say hi.  I realize that the Board Members and Volunteers will be very busy but we are never too busy to stop and speak with our members. We value your input and welcome your suggestions.

As a Member, you have the right to voice your opinions and provide suggestions. However, the most effective method of improvement is personal involvement.  If you desire change or would like to participate in the direction of your Association, I would respectfully request that you get involved.  There are many committees and projects that could use your assistance.  Another suggestion is to run for office.  We are looking for level headed individuals that can complete tasks on a reasonable schedule and enjoy the true value of working with others.  If you have any interest, please contact our election committee Chair, Tom Pierce at 661-619-3702.

And last but not least, I would like to thank each and every one of you for your support and assistance as I navigate through my presidency. Being the CCAI President is like being an engineer on a train.  I may drive the train but it takes the hard work of others to ensure that there is fuel in the engines, the cargo is secure, and the tracks are true.  Without this team, we could never deliver our training. These individuals are the Office Staff, the Board of Directors, and many strong Volunteers who make our Association run smoothly.

I personally thank those who participate in any way… regardless of the amount of assistance, as without this help…CCAI could not exist as we know it.  I would also like to thank those who have helped in the past and those that are considering any form of future participation.  This Association is built on the backbone of good people who know how to serve others.  We are wired to help and I am proud to be part of this incredible group.

Thank you again for your support and trust in my abilities.

Sincerely,

Dale W. Feb
CCAI President
