Warning Issued Regarding Fire Blankets and Electric Vehicle Fires

The Fire Protection Research Foundation (FPRF) and the Fire Safety Research Institute (FSRI) recently released an important notice highlighting serious safety concerns surrounding the use of fire blankets during fire suppression activities involving electric vehicles (EVs) with battery systems. The research indicates an alarming potential for explosion when these blankets are utilized to manage flames in EV fire incidents.

During testing, it was found that deploying a fire blanket successfully eliminated visible flames by restricting access to oxygen. This action, however, did not stop the ongoing thermal runaway phenomenon occurring within the EV battery, which continued to produce flammable gases even after the flames were smothered. This scenario led to dangerous gas accumulation beneath the blanket, which posed significant explosion risks for firefighters engaged in emergency operations near the involved vehicle.

Key Findings from Experiments

The experiments conducted by FPRF and FSRI focused on testing various fire suppression techniques centering on the complexities of EV fires. It was noted that while fire blankets could effectively quench external flames, the risk escalated when air was reintroduced to the gas-depleted environment under the blanket. Such an addition could ignite the flammable gases, potentially leading to explosions that jeopardize the safety of first responders.

Additionally, FPRF aims to research and refine fire suppression methods tailored specifically for EV incidents, emphasizing the need for better tools and tactics to protect firefighters and ensure efficient fire management. Their ongoing projects are evaluating the impact of different suppression techniques on the risk of re-ignition after an initial fire control effort.

On a parallel path, FSRI's research seeks to deepen our understanding of the hazards presented by EV battery-related fires and to develop effective strategies for controlling such incidents. They have been assessing the capability of traditional hose streams alongside those of fire blankets, marking a crucial intersection of innovation and safety.

The forthcoming reports detailing these research findings will be vital for industry professionals, particularly as the demand for EVs continues to grow globally. Key presentations are set to take place at the annual NFPA Conference and Expo scheduled for June 16, 2025, in Las Vegas. There, preliminary results will be shared, contributing to a broader dialogue on improving safety protocols in the face of evolving fire hazards.

The Role of Research in Fire Safety

Both FPRF and FSRI, with their commitments to enhance fire safety, play an essential role in informing the fire service community about significant emerging risks. Their studies are invaluable as they collaborate with scientists and laboratories worldwide, shedding light on fire safety challenges inherent to modern technologies such as electric vehicles.

In recognizing the ongoing changes in the automotive landscape due to the rise of EVs, it becomes increasingly necessary for fire safety protocols to adapt and evolve. These research initiatives underscore the importance of preparedness and informed response strategies in safeguarding those who serve on the front lines during fire emergencies.

As more insights emerge from these critical studies, it is imperative for firefighting agencies and first responders to stay informed and agile, ensuring not only their safety but also the effectiveness of their responses in the face of modern fire hazards.
