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.

CCAI-CFI-header1

The California Conference of Arson Investigators has patterned its CFI certification program after the State of California’s certification program with two major differences: 1) The CCAI – CFI program requires the applicant must stand for a written exam and 2) the CCAI-CFI certification requires participation in continued professional training.  To keep the certificate valid, a CCAI Certified Fire Investigator must attend 30 hours of approved tested training, or 40 hours of CCAI approved non-tested training or a combination of 40 hours tested and non-tested training every three years, from the date his or her certificate was issued.  The hourly training requirement can easily be met by attending two 20-hour CCAI training seminar’s within the three-year period.

To apply, a person does not have to be a member of CCAI; however it is strongly encouraged that everyone in the field of fire investigation belongs to the California Conference of Arson Investigators, the leading organization for training in fire and arson investigations in California.

To qualify, applicants must submit certificates of training showing that they have completed Fire Investigation 1A, 1B, 2A, 2B and PC 832 or its equivalent.  If you already possess a Level II Fire Investigation Certification from the State of California, a copy of your certification certificate showing Level II will suffice to validate that you have met the training requirements mentioned above.

Applicants must also validate that they have had the overall responsibility of, and have investigated, 150 fires to determine fire origin and separately to determine fire cause.  They must also substantiate that they have testified twice, in court or in deposition (not in the same case), under oath, pertaining to the origin and cause of fires or in the field of explosions.  The testimony can be criminal, civil or from deposition but must be directly related to fire origin and fire cause or origin and cause in an explosion incident.  In lieu of actual court related testimony, the applicant may complete any one of the below listed courses.

The following courses/classes will meet or substitute for the criteria of the court room requirements:

  1. The Bureau of Alcohol, Tobacco, Firearms and Explosives (BATF & E)  course on "Advanced Origin And Cause, Courtroom Techniques"
  2. The National Fire Academy (NFA) " course on Interview/Interrogation & Courtroom Techniques"
  3. The International Association of Arson Investigators (IAAI) " Expert Witness Courtroom Testimony  (Expert Witness Testimony Class offered by CCAI)

 

The question has risen, “If an investigator possesses a California State Fire Investigator II Certification, why would he/she have to verify again that he/she has investigated 150 fires and testified twice in court?”  It is the CCAI Board of Directors’ position that, if CCAI is going to certify an investigator, the person’s qualifications must be independently validated by CCAI using documents and under oath statements.

The initial application fee, if you are a CCAI member, is $150.00 and the certification is validated for three years.  Renewal of the CCAI-CFI certification, if you are a CCAI member, is $75.00 every three years.  If you are not a member of CCAI, the initial application fee is $300.00 and renewal is $150.00 every three years.
