The IAAI and CFITrainer.Net present these podcasts with a focus on issues relating to fire investigation. With expertise from around the world, the International Association of Arson Investigators produces these podcasts to bring more information and electronic media to fire investigators looking for training, education and general information about fire investigation. Topics include recent technologies, issues in the news, training opportunities, changes in laws and standards and any other topic that might be of interest to a fire investigator or industry professional affected by fire. Information is presented using a combination of original stories and interviews with scientists, leaders in fire investigation from the fire service and the law enforcement community.
Welcome to this edition of the IAAI’s CFITrainer.Net podcast. For our most recent episode, we had planned to focus on the Grenfell Tower fire, but due to ongoing litigation, we have to postpone our planned interview on that topic. We hope to bring you that in the future.
So, instead, we’re going to do a bit of a news roundup covering some interesting articles that have crossed our desktop lately.
A Johns Hopkins University study published in the journal Injury Prevention found that many Airbnb rentals lack basic fire safety protections, such as fire extinguishers and carbon monoxide detectors. Because Airbnb rentals are a “peer-to-peer hospitality service”—meaning they are short-term rentals of private homes—they are not subject to the regulations of hotels and motels and thus are not inspected to ensure fire protection and fire safety equipment are installed and working. Only 56% of over 120,000 Airbnb rentals in the study had carbon monoxide detectors and only 42% had fire extinguishers. 20% of Airbnb properties did not even have a smoke detector. This lack of safety standards for these types of properties leaves guests exposed to increased risk of death and injury. This gives the fire investigator a new angle to think about when assessing a residential fire, as well as occupant behavior.
Researchers at the University of Central Florida have developed a hazardous-gas detecting sensor that can detect and prevent fires aboard spacecraft. The sensor uses LEDs in the mid-infrared range to detect gases emitted by fire. This invention of course has obvious implications for space flight and off-world facilities like space stations and colonies on other planets. However, it may have applications for fire alarm design here on Earth, as well as a detection of harmful gases at fire scenes. And, if you’re just interested in the behavior of fire in extreme environments like space, we’ve got a link at the bottom of the podcast page to work being done by NASA and NIST to study the behavior of smoke in microgravity, where the normal laws of the buoyancy of gases do not apply and smoke moves in long chains or large particles spreading in all directions.
FEMA has documented at least 195 cases of e-cigarettes and vape pens exploding and catching fire. The problem is overheating of the lithium-ion battery. Now, fire investigators have identified the first fatality attributed to a vape pen explosion. Autopsy confirmed that a 38-year-old Florida man was killed when his vape pen exploded, sending shrapnel into his head and starting a fire in his home. Fire investigators working scenes where vape pens and e-cigarettes are present should evaluate these items as potential fire causes.
And, finally, we come to the goats. Apparently, goats pull their weight in fire prevention. Thanks to the research of three high school students in Colorado, we now know that goats are effective in reducing dense, gambrel oak that is a major fuel for wildfires and that their activity to do so has little negative environmental impact. Goats as clearers of brush is not a new idea, but now we have some scientific data on its effectiveness. Just in case you were wondering, at least in Colorado, it costs about $1000 for 300 goats who can take care of 1 acre in an hour.
A quick tip to keep up on the news yourself. You can set up Google Alerts to deliver interesting fire investigation articles to your email inbox. Just go to google.com/alerts, type in a term that describes the type of news you want, for example “fire investigation,” enter your email, and click Create Alert.
