Most house fires are incredibly rapid and intense, giving you just about three minutes after an alarm sounds to evacuate safely. Now, a local Chicago-area lab is working tirelessly to save lives and property through cutting-edge research.

This initiative represents a novel approach aimed at curbing fires quicker than traditional methods. As John Drengenberg, consumer safety director at Underwriters Laboratories, explained, “We're standing inside what appears to be a regular home—no furniture, no decorations.” This renowned organization, famous for safeguarding consumers, has set up this project within a custom-built warehouse in Northbrook. Experts and firefighters from across the nation are collaborating on this endeavor.

Within 45 seconds of igniting the fire, thick clouds of smoke began pouring out of the roof. By two minutes, flames had erupted, consuming the entire structure. The fire raged for half an hour, reaching scorching temperatures of 500 degrees Fahrenheit. Firefighters are meticulously analyzing various techniques to determine the fastest and most effective ways to douse flames.

"It’s not as straightforward as simply spraying water everywhere or using a specific nozzle type," noted Steve Kerber, director of the UL Firefighter Safety Research Institute. "Understanding how fires spread involves combining multiple suppression strategies."

Researchers are also focusing on optimizing the application of water during firefighting efforts. In this experiment, the fire was deliberately started in the attic. "We’ve noticed an uptick in attic fires due to modern insulation practices. Fires originating outdoors can easily creep into attics, especially when triggered by lightning strikes or electrical malfunctions," Kerber added.

Regrettably, escape windows have become narrower due to advancements in household materials. Items such as synthetic cushions, furniture, and construction supplies burn far quicker and hotter compared to older natural alternatives. Previously, you'd have 17 minutes to act after hearing an alarm. Today, that window has shrunk drastically to just 3-4 minutes.

Fire prevention specialists emphasize the importance of routine maintenance for electrical systems, HVAC units, and chimneys. Additionally, thorough inspections of these areas should be conducted prior to moving into a new space.

"Identifying hotspots—both literal and metaphorical—is crucial for both firefighter safety and occupant well-being," Drengenberg concluded.

Once complete, the comprehensive findings from this firefighting study may take several months to finalize. Underwriters Laboratories plans to distribute these valuable insights nationwide to fire departments across the country.

Thanks, Dan!
