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.
At the door:
Kia Motors America (Kia) is recalling certain model year 2014 Kia Forte vehicles manufactured December 5, 2012, to April 17, 2014. In the affected vehicles, the cooling fan resistor may overheat and melt.

Wind blowing into the broken window of a room on fire can turn a "routine room and contents fire" into a floor-to-ceiling firestorm. Historically, this has led to a significant number of firefighter fatalities and injuries, particularly in high-rise buildings where the fire must be fought from the interior of the structure.
On April 12, 2009, a fire in a one-story ranch home in Texas claimed the lives of two fire fighters. Sustained high winds occurred during the incident. The winds caused a rapid change in the dynamics of the fire after the failure of a large section of glass in the rear of the house.

NIST performed computer simulations of the fire using the Fire Dynamic Simulator (FDS) and Smokeview, a visualization tool, to provide insight on the fire development and thermal conditions that may have existed in the residence during the fire.

The term "spoliation" refers to the loss, destruction or alteration of an object which is evidence (or potential evidence) in a legal proceeding. It is a concept first recognized by courts in England more than a century ago which has only recently taken on significance in this country. However, it is an issue of particular importance to the field of fire investigation and will likely become increasingly significant as courts are called to decide the consequences of lost or altered physical evidence in fire litigation cases.
