Factors controlling the spread of smoldering combustion on solid wood (red oak, white pine) were examined in a configuration designed to enable self-sustained smolder. The sample was in the form of a U-shaped channel 74 em long with 6.4 em thick walls. A controlled flow of air was confined to the interior of the channel. Smoldering was initiated on the interior surface either of the upstream end of this channel (yielding forward smolder propagation), the downstream end (reverse smolder) or mid-length (coupled forward/reverse smolder). In separate tests the air flow velocity (referred to the initial cross section of the channel) was varied from about 9 to 22 em/sec. At the low end of this range, the smoldering process was prone to extinction; at the high end it was increasingly likely to transition into flaming combustion. A simple energy balance model indicates a central role of radiative transfer in sustaining the smolder process.

This recall involves model year 2014 Arctic Cat Prowler 500 HDX and model year 2015 Prowler 500 HDX models. The recalled vehicles include vehicle identification numbers (VIN) from 303194 through 305166. The VIN number is located on the rear frame tube under the rear of the box. The vehicles are green, red, vibrant red metallic, or emerald green metallic. “Arctic Cat” is printed on each side of the hood. Also 500 is printed on each side on the front fenders, HDX on each side of the rear cargo box, and “Arctic Cat” on the cargo box tail gate.
Kim Warner got the scare of her life behind the wheel of her Jeep Wrangler. "I saw a flash under the hood," she remembers. She says she was driving at a low speed when her brakes went out and the shifter jammed. "I had both feet on the brake and my tires were spinning. I noticed flames coming out the passenger side," she says.
Her boyfriend who was nearby ran, jumped in, and pulled her out of the SUV before it got worse. "As I pulled her out that is when the flames came thru the dash," he said.
Chrysler sent an inspector, but the automaker said in a statement: "The cause of the fire was deemed inconclusive by the investigator."
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.
This recall involves battery-operated night lights with an AC adapter included. The night light collection includes a pink hedgehog, a blue bird, a yellow rocket, an orange dino egg, a white soccer ball and a green shark. The model numbers are printed on the bottom side of the night lights.
UNDER ADVISEMENT RULING
The Court has had under advisement Plaintiff Barbara A. Sloan’s (“Sloan”) Rule 60 Motion. Having read and considered the briefing and having heard oral argument, the Court issues the following ruling.
This recall involves four types of DD branded single-wick candles: Mason jars in 5- and 12- ounce sizes, decorative jars in 10- and 20-ounce sizes, 13-ounce coffee tins and 13-ounce jars with a holiday theme. The candles were sold in a variety of fragrances and colors.
The 5-ounce Mason jars are 2.25 inches wide by 3.75 inches high. The 12-ounce Mason jars are 3 inches wide by 5 inches high. The jars have gray metal lids. The DD logo and the word Handcrafted are in raised letters on the front of the jars. The candle fragrance and size are printed on a hang tang attached to the mouth of the jars.
The 10-ounce decorative jars are 4 inches wide by 3 inches high. The 20-ounce decorative jars are 5 inches wide by 4 inches high and hold a candle. The jars have gray metal lids with the DD logo in raised letters on the top. The candle fragrance and size are printed on a rectangular label on the front of the jar.
The 13-ounce coffee tins are 3.5 inches wide by 4 inches high and have a silver metal lid. The candle size and fragrance are printed on a label that wraps around the outside of the tin.
The 13-ounce holiday candle jars are 3.75 inches wide by 4 inches high and have silver metal lids with the DD logo in raised letters on the top. The DD logo inside a floral wreath, the fragrance and size are printed directly onto the front of the jar in silver.

Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain model year 2011-2012 Toyota Avalon vehicles manufactured February 9, 2010, to October 22, 2012. In the affected vehicles, the sub-woofer speaker located in the trunk may experience an intermittent electrical short which may cause damage to the integrated circuit (IC) in the audio amplifier. In some cases, the damaged IC may allow a constant electrical current flow to the sub-woofer.

Nova Bus (Nova) is recalling certain model year 2007 LFS transit buses manufactured January 1, 2007, to December 31, 2007. In the affected vehicles, the band clamp on the flex pipe between the turbocharger and the diesel particulate filter may be incorrectly located allowing the exhaust pipe to leak hot exhaust gases onto nearby components.

Fire Protection Research Foundation report: "Development of Standardized Cooking Fires for Evaluation of Prevention Technologies: Data Analysis"Authors: Joshua Dinaburg, Daniel Gottuk – Hughes Associates, Inc.
Beginning in 2010, the Foundation began a program to review the potential effectiveness of various technologies potentially capable of preventing cooking range top fires. A workshop conducted as part of that project considered the emergence of commercial products on the market and identified the need to develop standardized tests and criteria to evaluate the performance and effectiveness of such devices. This report summarizes and analyzes the results of two live fire test series conducted to form the basis for such a test protocol.
Cooking-equipment related fires are a leading cause of U.S. fire loss. Beginning in the mid 1980’s, the National Institute of Standards and Technology, Consumer Product Safety Commission, and home appliance industry undertook a comprehensive review of strategies to mitigate death, injury and property loss from cooking fires. All strategies were engineering strategies defined by a condition to be detected (e.g., overheat of pan or food in pan, absence of person actively engaged in cooking process, early-stage fire on stovetop) and an action to be taken (e.g., shut off cooking heat, sound alarm, suppress fire). As part of this study, a comprehensive review of existing technologies was done.
In 2010, the Foundation conducted a study supported by NIST to develop this action plan. The study focused particularly on prevention technologies suitable for use on or with home cooking appliances. and consisted of a literature and technology review; the development of an enhanced technology evaluation methodology based on an in-depth review of cooking fire statistics; and the evaluation of currently available technologies using this methodology. The project culminated with a one day workshop of 35 leaders from the kitchen appliance, fire service, and user communities who met to review the above findings and identify gaps in information. The highest priority action item identified at that workshop toward implementation of commercially available cooking fire mitigation technologies was: "Develop standard fire scenarios and create test methods and performance criteria which can feed into standards development"
This report presents the results of a follow on project sponsored by NIST to gather data towards this goal.
