Abstract

Experiments were conducted to assess the performance of various residential smoke alarms to kitchen fires and nuisance alarm cooking scenarios.  A structure representing a kitchen, living room and hallway was constructed to conduct the experiments. Eight different residential smoke alarms types, two photoelectric models (P1 and P2), two ionization models (I1 and I2), two dual sensor photoelectric/ionization models(D1 and D2), and two multi-sensor, intelligent models (M1 and M2) were used in this study.  The data gathered provided insight into the susceptibility of alarm activation from exposures to typical cooking events and alarm times for actual kitchen fires.  The effects of alarm technology and installation location on the propensity of an alarm to activate were examined.  In the kitchen fire experiments, all smoke alarms responded before hazardous conditions developed.  An ionization alarm (I1) tended to respond first compared to other co-located alarms.  Results show smoke alarms placed greater than 6 m from the kitchen range may provide less than 120 s of available safe egress time, which suggests the importance of a more central alarm location closer to the kitchen for this configuration.  Experiments were conducted to determine an alarm’s propensity to activate when exposed to particulates generated from eight typical cooking activities including toasting, frying, baking and broiling.  In most cases, the propensity to nuisance alarm decreased as the distance from the cooking source increased.  Two alarms, I1 and D2, experienced more nuisance alarm activations across the eight cooking activities than the other alarms.  The remaining alarms experienced about the same combined nuisance alarm frequency by averaging all cooking events for installation locations outside the kitchen.  Experiments showed combustible materials typically found on a counter top can spread flames to overhead cabinets, and a single empty 0.6 m wide 1.0 m tall wood-framed, pressboard cabinet can produce a peak heat release rate nearly sufficient to flashover a small room.  Alternatively, protective metal barrier on the bottom and side facing the range tended to limit the spread of flames to the cabinet and reduce the heat release rate.

DETROIT (WXYZ)

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."

Loose engine cover could cause fire

Fiat Chrysler is recalling 350,000 Dodge Journey crossovers due to a problem with the vehicle’s engine cover that could lead to a fire.

The covers can become dislodged and come in contact with exhaust components preventing them from moving. If that happens, it could cause a fire. The company has reports of three fires in Chile, involving one injury and no deaths.

Surviving fires: How common mistakes can lead to devastating fires

Shared by Jamie Novak, St Paul Fire Department

Surviving_firesCOON RAPIDS, Minn. - Fire does not schedule home visits, nor do firefighters arrive by appointment.

In the interest of fire safety, we decided to change that.

During two days of shooting, a crew of firefighters and KARE 11 photographers with a dozen cameras gathered at the most deadly place for fires in Minnesota: home.

Jamie Novak, a St. Paul Fire investigator, helped us locate a three-bedroom rambler in Coon Rapids that was already scheduled for demolition.

Cooking fires: do you know what to do?

Shared by Jamie Novak, St Paul Fire Department

cooking-oil-fireST. PAUL, Minn. - If anyone knew her way around a kitchen, it was Wille Mae Coleman. No one could count the number of times she'd fried chicken for supper. Then last August, alone at the stove in her apartment, the 75-year-old grandmother died doing it.

"I vividly remember getting the phone call," says her son Don Coleman, somberly. "Very difficult, that's my mother." Wille Mae suffered serious burns on 70 percent of her body. He was with his mother at Regions Hospital when she died.

Investigators: Fire safe smokes?

Shared by Jamie Novak, St. Paul Fire Department

safe_smokesMysterious house fires are happening a lot more than officials had expected, and so-called "fire safe" cigarettes are a common culprit.  FOX 9 Investigator Jeff Baillon found the special paper that's supposed to "self-extinguish" can still be a smoldering risk, and lawmakers are now looking into it.

Sun, vodka bottles start fire inside Burnsville liquor store

Shared by Jamie Novak, St. Paul Fire Department

Vodka-fireBURNSVILLE, Minn. (KMSP) - Burnsville fire officials say they've never heard of so-called firewater could become a starter without the aid of a match or spark, but that's exactly what happened when vodka bottles magnified sunlight and started a fire inside Red Lion Liquors.

The store has been in Burnsville since 1978, and it's occupied its current building for the past nine years. They have bulletproof glass to stop burglars and vandals from breaking in, but that couldn't' protect them from a problem that started inside.

The Goal is Truth

By Paul Francois & Enrique Garcia
Third Degree Communications

When testifying in court as to the manner in which we conducted an interview, defense counsel will often ask us whether we just wanted his client to "confess." We answer that we do not seek confessions  but rather truth. After all, no good cop is interested in false information, only truthful information. That is why our motto at Third Degree Communications is "Nothing but the Truth."

One little tidbit we impart on our students to help convey this concept is by reminding them that if obtaining the truth is their ultimate goal, then they should be doing nothing that might prevent them from obtaining the truth. For example, getting angry with a subject who is lying would most likely sever rapport and interfere with accomplishing the goal of obtaining the truth. Raising my voice, insulting him, or speaking to him in a condescending manner are all most likely going to be rapport killers that will stymie my ability to get to a successful and truthful outcome with the subject. If we want to get people to provide us with truthful information, we should avoid doing anything that will interfere with accomplishing this goal.

This actually applies to many areas of our lives if we think about it. Let's say I've made a new year's resolution to avoid gossiping about other people. There are several steps I can and should consider that will help me accomplish this goal, including but not limited to:

  •  Avoiding certain people who I know thrive on gossip
  • Not asking certain questions that are more likely to lead to gossip, such as "Who did that?" "What are you guys talking about?" "What happened next?"
  • Excusing myself from conversations that turn in the direction of gossip

In the same manner, if my goal is to obtain truthful information, I must only engage in behavior that's more likely to help me accomplish this goal and to avoid behavior that will interfere: 

  • Treating people with dignity and respect
  • Manipulating my tone of voice to maximize my effectiveness
  • Establishing rapport
  • Being a compassionate, empathetic listener
  • Projecting an image of being non-judgmental and accepting

 

Getting people to tell the truth means creating an environment that is conducive to helping them cooperate. Obtaining our goal means everything that I say and do is oriented toward achieving that goal. It's a remarkably simple concept, but a critical one to remember throughout the interview.
