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.

From the Danish Journal of Archaeology

Abstract

During excavations of the Viking-age ring fortress Borgring, Denmark, traces of a devastating fire was uncovered. The National Forensic Services of the Danish Police were invited to participate in a novel collaboration, applying contemporary forensic fire investigation to an archaeological site. This paper presents the results and sets a benchmark for future applications. The investigation leads to a revised reconstruction of the fortress and the development of the fire. The application of fire investigation methods, following the Daubert standard criteria, enhance the documentation and analysis of archaeological sites, while archaeological methods show significant potential at modern fire scenes.

BY VYTO BABRAUSKAS

SHOCK, INJURY, OR DEATH {ELECTROCUTION) from the passage of electric current through a human body has been studied for more than a century. The level of response or injury depends on the magnitude of the current and also on the frequency, whether it is direct current (DC), power line alternating current (AC), or AC voltages of higher frequency. Some typical values are shown in Table 1.1 Children are generally more sensitive than adults; thus, guidelines often assume that a child is the person to be protected. With firefighting, however, this assumption is not reasonable. Furthermore, protection against a startle reaction is the most severe level of protection. A startle reaction is described as one in which a person jumps because of a small shock that does not injure the person. No direct electrical injury occurs because of startling; there is some hazard caused by jumping, but it is remote.

The "inability to let go" of an energized conductor that has been accidentally grabbed can cause pain and injury if the current increases to an injurious level. This is also called "muscle tetanization." Thus. Many safety requirements are based on a safety-factor-reduced value of the let-go current, even though this is quite a conservative stance. Matters are further complicated. Since individuals show variation in their responses and standards, bodies typically pick a very conservative level (often the 0.5 percentile) instead of the 50-percentile value. Physiological effects of electric current, furthermore, depend strongly on frequency. The most dangerous frequencies are the 50- or 60-Herz (Hz) power line frequencies. The human body becomes less sensitive to electric current at high frequencies.2 Dalziel3 has published a useful summary of safety guidance on electric shock.

"Ski" Scholarship

Ski_web"SKI Scholarship" applicants must be a public sector investigator and be from an agency that does not have funding available. Applicants that are forced to pay out of pocket in order to attend our conferences are encouraged to apply. The number of available scholarships is dependent on the amount of contributions we receive, but there can be as many as three recipients per conference. Scholarship funding can be applied toward:

1) Membership registration (if they are not current members)
2) conference registration
3) hotel lodging
4) meal expenses
5) travel expenses
