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.

Fuel Delivery Line Corrosion may Cause Fuel Leak

SUMMARY:

Suzuki Motor of America, Inc. (Suzuki) is recalling certain model year 2013 Suzuki SFV650 motorcycles manufactured March 23, 2013, to April 8, 2013, 2014 Suzuki SFV650 motorcycles manufactured October 24, 2013, to November 26, 2013 and 2015 Suzuki SFV650 motorcycles manufactured August 9, 2014, to September 12, 2014. During assembly of the motorcycle, the fuel tank breather hose may have not been positioned properly and may become kinked. 

CONSEQUENCE:

If the fuel tank breather hose is kinked, pressure may build inside the fuel tank and cause the tank to crack, resulting in a fuel leak, increasing the risk of a fire.

Hoverboards Put On No-Fly List, As Airlines Cite Fire Concerns

Hoverboards like the one seen here won't be allowed on flights by America's top three airlines, which are citing a potential fire hazard related to the self-balancing scooters' powerful lithium-ion batteries.Citing a potential fire hazard, major U.S. airlines are banning hoverboards from their cabins and cargo holds. Announcing its ban, Delta acknowledged the toy's "presence on many gift lists this holiday season" but said safety comes first.

The bans come as the U.S. Consumer Product Safety Commission says it's looking into at least 10 reports of the self-balancing electric scooters bursting in flames — an occurrence that's allegedly been captured on video, in some cases.
