Historic Fire Investigation Case: The Charleston Sofa Super Store Fire from 2007. 🔥🔥🔥

On June 18, 2007, a devastating fire at the Sofa Super Store in Charleston, South Carolina, claimed the lives of nine Charleston firefighters.

The fire began in discarded furniture and packing materials outside the store's loading dock area. Flames spread into the building and eventually reached the large furniture showrooms and warehouse. The combination of heavy fuel loads, large open spaces, limited ventilation, and the absence of an automatic sprinkler system contributed to the fire's rapid development.

Investigators determined that as the fire grew, large amounts of smoke and unburned combustible gases collected above the showroom ceiling. When the front windows were broken, additional oxygen entered the building, allowing the fire to intensify rapidly and spread throughout the showroom.

The Charleston Sofa Super Store fire remains one of the most significant tragedies in modern American firefighting history. It serves as an important reminder of the dangers of rapidly changing fire conditions, ventilation-limited fires, combustible contents, and the importance of building fire protection systems.

As fire investigators, we must continue to study and learn from incidents like this. By understanding how fires start, spread, and develop, we can use that knowledge to improve our investigations, strengthen fire prevention efforts, and help protect firefighters and the communities we serve.

We honor the Charleston Nine and their ultimate sacrifice by continuing to learn from the past and using those lessons to help prevent future tragedies. ❤️🚒

🌽🚜 Harvest Season in the Hoosier State 🚜🌽
The Indiana Chapter of the International Association of Arson Investigators would like to recognize and thank the hardworking farmers who help feed our communities, our state, and our country. As harvest season continues across Indiana, we wish all of our farmers a safe and successful harvest.

With long hours in the fields and heavy equipment working in dry, dusty conditions, harvest season can also bring an increased risk of machinery and field fires. Combines, tractors, and other agricultural equipment operate around dry crops and crop residue, where a small heat source or mechanical problem can quickly become a serious fire.

🔥 A few simple precautions can make a big difference:
• Keep properly rated and maintained fire extinguishers readily accessible on equipment.
• Regularly remove accumulated crop debris, dust, and chaff from machinery, especially around engines, exhaust systems, bearings, and other heat-producing components.
• Inspect equipment for fuel, oil, hydraulic, and electrical problems before heading to the field.
• Watch for unusual smells, smoke, overheating, or mechanical problems while operating equipment.
• Keep a phone available and know the location of the field so emergency responders can be directed there quickly.
• If a fire occurs and cannot be safely controlled, move to a safe location and call 911.

To Indiana's farmers: thank you for what you do. Please take the extra time to protect yourself, your equipment, and your livelihood this harvest season.
Stay safe, Indiana. 🌽🚜🇺🇸

🔎Okay Fire Investigators, we want to hear from you!

Tell us about your most recent lithium-ion battery fire investigation. What was the biggest challenge you encountered during the investigation? And from your experience, what do you believe is the biggest challenge facing the fire service and the public as lithium-ion batteries become increasingly common?🔥

Drop your experiences in the comments. Sharing what we're seeing in the field helps all of us become better investigators and gives us another opportunity to educate the communities we serve.

This year’s Fire Prevention Week campaign brings attention to an issue fire departments and fire investigators are seeing more and more—lithium-ion battery safety.🔋

Lithium-ion batteries are everywhere. They power our cell phones, laptops, power tools, e-bikes, electric vehicles, hoverboards, portable power stations, toys, and countless other devices we use every day.🪫

When these batteries are damaged, improperly charged, exposed to excessive heat, modified, or used with incompatible charging equipment, the results can be serious. Battery failures can involve rapid fire growth, extreme heat, toxic gases, thermal runaway, and the potential for re-ignition.⚠️

Training. Education. Collaboration. A Safer Indiana.

🔥 Indiana IAAI Myth vs. Fact — Crazed Glass

MYTH: 🔎
“Crazed glass proves that a fire burned rapidly or that an accelerant was used.”

FACT: 🫆
Crazed glass, by itself, does not prove rapid fire growth or the presence of an ignitable liquid. Modern fire-investigation research has shown that crazing can occur when heated glass is rapidly cooled, including when water from fire-suppression activities contacts hot glass.

Crazed glass generally appears as a complicated network of short, straight or crescent-shaped cracks.

The important investigative takeaway is that investigators shouldn't use crazed glass alone to make a determination about fire cause or ignitable-liquid involvement. It needs to be evaluated along with the totality of the scene evidence.

Historic Fire Investigation Case: The Station Nightclub Fire 2003. 🔥🔥🔥

Pyrotechnics used during a Great White performance ignited combustible polyurethane foam near the stage in the nightclub. The fire spread extraordinarily quickly, and 100 people died.

Investigators had video evidence showing ignition and rapid fire development. The Station Nightclub fire remains one of the most significant cases in modern fire safety and investigation, providing important lessons in fire behavior, rapid fire development, combustible interior finishes, and occupant evacuation.

As fire investigators, it’s imperative that we thoroughly investigate, study, and learn from tragedies such as the Station Nightclub fire. By understanding how and why these incidents occur, we can apply those lessons to improve fire prevention, strengthen safety practices, and help prevent similar tragedies from occurring in the future.

We honor those who were lost by continuing to learn from the past and using that knowledge to help protect lives in the future.

The Indiana Department of Homeland Security describes arson as a leading cause of property damage and loss in Indiana.

According to the April 2025 edition of the Hoosier Responder, the Indiana State Fire Marshal’s Fire Investigations Section handles approximately 600 fire and explosion investigations each year across the state.

Behind every investigation is the important work of determining the origin and cause, preserving evidence, documenting the scene, and, when a fire is intentionally set, helping ensure those responsible are held accountable.

These numbers are a reminder of just how important trained and dedicated fire investigators are to communities throughout Indiana.

The Indiana Chapter of the International Association of Arson Investigators is proud to support fire investigators through training, education, professional development, and collaboration as we work together to advance the profession and protect the communities we serve. 🇺🇸🇺🇸🇺🇸
