Lithium Fire Guard

A domestic SAS flight yesterday had to declare a Mayday and divert to Trondheim after a power bank overheated in the cabin, producing smoke and triggering a full emergency response. Several crew members were treated for smoke inhalation, and the aircraft landed safely, but the event is now under investigation. Incidents like this highlight how a single lithium-powered device can disrupt an entire flight and why proactive lithium battery risk mitigation, crew training, and certified containment solutions are becoming essential equipment for every commercial and corporate aircraft.

Lithium Fire Guard’s PG100 is built and tested to the toughest battery fire containment benchmark in the world: the ANSI/UL 5800-2021 Standard for Battery Fire Containment Products, used jointly in the U.S. and Canada for inhabited aircraft compartments.​

How rigorous is ANSI/UL 5800?
- It uses a controlled “worst-case” lithium-ion battery failure, driving 18650 cells to full thermal runaway at 100% state of charge to prove true containment, not just “overheating” resistance.​

- Products are tested three separate times with new units each time; if any test fails key criteria, the entire program stops.​

- The test lab instruments temperature, smoke, and combustion products every second for up to six hours, monitoring surface temperatures, smoke release, and debris in a highly controlled fire test environment.​

What does a passing product have to do?
To meet performance levels under UL 5800, the containment system must:
- Prevent flame from breaching the product (even with cheesecloth and tissue wrapped around it to detect the smallest ignition).​

- Keep shrapnel, sparks, and harmful debris fully contained, while keeping exterior touch surfaces below strict temperature limits for handles, vents, and contact surfaces.​

For higher performance (Level 2), keep total visible smoke release under a tight maximum, on top of all the above requirements.​

Why this matters for PG100

When an operator deploys a UL 5800–qualified containment like Lithium Fire Guard’s PG100, they are using a system designed specifically for inhabited aircraft cabins, tested to contain a full-blown lithium battery thermal runaway events and engineered so a single trained person can operate it with clear instructions and built‑in PPE requirements.​

If your lithium battery safety solution has not been proven against ANSI/UL 5800, you are relying on marketing claims instead of a rigorous, independently developed aviation fire-containment standard—exactly why operators looking for real risk reduction choose solutions like Lithium Fire Guard’s PG100.

FAA official tests prove most containment bags fail to stop toxic smoke or fully contain dangerous lithium battery fires—they let hazardous gas escape and struggle to isolate a burning device. See what happens when containment falls short: toxic smoke fills the cabin and devices propagate. Safety must improve.

We were pleased to be featured in the recent issue of Dockwalk. As awareness of lithium battery fire risks continues to grow, the marine industry is beginning to evolve. Insurance providers and Class societies are developing new protocols and policies to address this emerging challenge.

See the excerpt and full article from the November 2025 issue below, and feel free to contact us to schedule a consultation or reserve your Smart Charge Box as we begin rolling out units early next year.

"Currently, there is no industry guidance on PED-related lithium battery incidents. The MCA's MGN 681 addresses only "vehicle-type" batteries. Class societies often omit PEDs entirely. Yet, these are the very devices most likely to cause an incident, especially when used and charged in enclosed, poorly
ventilated areas on board, such as guest and crew areas.

With LFG's solutions, crew can act swiftly and safely to address lithium battery risks by bridging the gap left by existing marine safety guidance. Advanced tools, like the PG-100 should be essential, indispensable parts of maritime protocols, not optional enhancements. LFG is also currently working on a Safe Charging Box and a Safe Storage Box. A proactive approach has the potential to turn risk management from a reactive endeavor into a cornerstone of operational maritime excellence."

In light of ongoing concerns about the risks posed by lithium battery fires in everyday settings—including our schools—it's essential to rely on the most advanced, proven solutions for protection. The PG 100 is a great option for schools: unlike simple containment bags, our innovative polycarbonate ballistic blast shield offers superior protection by physically isolating and shielding users from explosions and ballistic threats, not just enclosing the hazard.

Our shield is engineered using multi-layered polycarbonate, known for its blast and ballistic resistance, ensuring peace of mind in environments where safety is paramount. Polycarbonate shields, like those found in industry-leading models, are trusted worldwide for child and staff safety due to their durable, impact-resistant design. As recent reports indicate, schools and parents are increasingly seeking reliable protective measures against battery-related incidents and other threats, making the PG 100 a timely, effective choice for educational institutions.

Choose the PG 100 ballistic blast shield for true safety—not just containment. Let's work together to make our schools more secure for everyone.

Today, Lithium Fire Guard proudly recognizes all those who have served our country—especially our own team member and co-owner, whose service as a Vietnam helicopter pilot continues to inspire both our company and the aviation safety industry.

The same values that define great service members—discipline, teamwork, and integrity—are the foundation of safe operations throughout aviation and marine environments. Veterans bring leadership, precision, and excellence to every mission, every hangar, and every flight.

We also honor the families who stand beside our service members—their strength and unwavering support make every mission possible.

To every veteran inside and outside of aviation: thank you for your service, your sacrifice, and your steadfast commitment to safety and excellence. Your legacy is felt in every life we protect and every innovation we pursue.

Happy Veterans Day from all of us at Lithium Fire Guard. We stand with you, we salute you, and we are deeply grateful for your courage and dedication.

Thank you, Veterans!

In the world of luxury yachting, safety is not optional it’s essential. The Lithium Fire Box is an advanced life-saving solution designed specifically to address one of the most dangerous risks onboard: lithium battery fires.
Unlike land-based environments, yachts often lack immediate external support during emergencies. That’s why the Lithium Fire Box offers autonomous protection, engineered to detect abnormal temperatures and automatically isolate electrical hazards before a fire can escalate.

How It Works:
• The system includes a fully sealed lithium battery compartment equipped with a dedicated temperature probe that continuously monitors internal conditions.

• If the temperature rises beyond a safe threshold, a signal is sent through the
temperature controller to:
o Instantly de-energize nearby electrical outlets, eliminating ignition sources.
o Alert the AMS (Alarm Monitoring System) with a critical warning.
o Activate both visual and audible alarms throughout the vessel.

For maximum safety, alarms cannot be silent automatically. A manual reset at the main breaker is required, ensuring a qualified crew member physically inspects the compartment before restoring power.

• ✔ Early Intervention – Stops a thermal event before it becomes a catastrophe.
• ✔ Critical for Remote Environments – Ideal for yachts far from shore support.
• ✔ Human Confirmation Required – Forces inspection before reset, no silent resets.
