• Growing global concern over lithium-ion battery fires drives demand for specialized suppression technologies 
• Ottawa Fire Services completes first purchase of FCL-X™ lithium-ion battery fire response solutions by a Large Canadian Municipal Fire Service.
• FCL to showcase solutions and meet international partners at INTERSCHUTZ 2026 in Hannover, Germany

TORONTO, June 1, 2026 /PRNewswire/ - Full Circle Lithium Corp. ("FCL" or the "Company") (TSXV: FCLI) (OTCQB: FCLIF) (FSE: K0Q), a leading North American manufacturer of lithium-ion battery fire extinguishing products, is pleased to announce its first Canadian municipal fire service sale to Ottawa Fire Services for FCL-X™ fire suppression solutions designed specifically for lithium-ion battery fire response and containment, through its Canadian dealer Safetek-Profire. Other Canadian Fire Services have expressed interest and are expected to purchase in the near future. 

The milestone represents a significant advancement in supporting the Canadian Fire Services as they confront one of the fastest-growing operational and public safety challenges facing emergency responders today: lithium-ion battery fires associated with Electric Vehicles, E-bikes, E-Scooters, energy storage systems, tools, and consumer electronics.

"We are extremely proud to support Canada's Fire Services with specialized solutions specifically for lithium-ion battery incidents," said Carlos Vicens, CEO of FCL. "Ottawa is demonstrating leadership by proactively equipping their teams for the evolving risks associated with electrification and energy storage technologies."

Across Canada, fire services have reported a growing number of lithium-ion battery-related incidents in recent years. Toronto Fire Services reported a 90% increase in lithium-ion battery fires in 2023 compared to 2022¹, while Ottawa Fire Services recently confirmed more than 50 lithium-ion battery-related fires since 2024². Similar incidents involving E-Bikes, E-Scooters, Charging Systems, and Battery Storage devices continue to challenge fire departments globally.

The issue extends far beyond North America. Fire services across Europe and the United Kingdom have experienced substantial increases in lithium-ion battery fires tied to e-mobility devices and energy storage systems. London Fire Brigade recently reported record levels of e-bike and e-scooter fires³, while UK fire brigades are now responding to lithium-ion battery-related fires approximately every five hours⁴.

"This is clearly a global fire safety challenge," added Carlos Vicens, CEO of FCL. "Lithium-ion battery incidents are occurring across Europe, Canada, the United States, and other International markets as electrification accelerates. Fire departments everywhere are looking for practical solutions for suppression, containment, and operational response that improve firefighter safety and incident management.

FCL's integrated fire suppression products are designed to help first responders manage thermal runaway events, improve operational safety, and support rapid stabilization during high-risk battery fire incidents.

INTERSCHUTZ 2026 – Hannover, Germany

The company also announced its participation in INTERSCHUTZ, the world's premier trade fair for fire and rescue services, civil protection, and safety technologies. FCL has already scheduled several meetings with international fire service leaders, distributors, municipal agencies, and industry partners during the conference as part of its expanding global outreach strategy.

"INTERSCHUTZ is one of the most important international platforms for innovation in fire and rescue services," said Carlos Vicens. "We are looking forward to meeting with departments and organizations from across Europe and around the world that are actively seeking solutions for lithium-ion battery fire risks."

As electrification continues worldwide, FCL remains committed to supporting emergency responders globally through innovative technologies and practical solutions tailored to the rapidly evolving risks posed by lithium-ion battery systems.
