HOT-STOP® 'L' Evo Oversized Tablet – Aircraft Lithium-Ion Battery Fire Containment Bag

For proper readiness, the HOT-STOP® ‘L’ oversized tablet containment bag should be stored unzipped with the pull strap positioned over the hook-and-loop closure. This staging method allows the bag to be deployed quickly during a lithium-ion battery incident involving a large tablet or similar device.

Because the bag is made from flexible fire-resistant materials, it can be stored compactly in cockpit or cabin emergency equipment compartments. Operators should periodically inspect the zipper and apply a light beeswax lubricant to ensure smooth operation.

To deploy the bag, crew members should retrieve the containment kit and put on protective gloves if available. The overheating or damaged tablet should then be carefully placed inside the bag beneath the internal baffle system.

Next, pull the red “PULL” tab to close the hook-and-loop seam and zip the bag completely until the zipper reaches the stopper. Properly sealing the bag helps contain heat, flames, and smoke generated during a lithium-ion battery thermal runaway event.

Yes. HOT-STOP® ‘L’ fire containment bags are backed by a lifetime replacement warranty if the bag is deployed during an actual lithium-ion battery thermal runaway incident.

After such an event, operators must complete an incident report and return the used bag to the manufacturer for evaluation and replacement. This warranty program reflects the manufacturer’s confidence in the bag’s fire containment performance.

The HOT-STOP® ‘L’ containment system has undergone burn testing in FAA-registered laboratories. Official burn test certificates and supporting documentation are available from the manufacturer.

These tests demonstrate the bag’s ability to withstand the extreme heat, pressure bursts, and smoke associated with lithium-ion battery fires. Operators can reference this documentation during safety audits or regulatory compliance reviews.

The HOT-STOP® ‘L’ oversized tablet containment bag is constructed with multiple layers of fire-resistant materials, an airtight zipper system, and internal baffles. These features help trap flames, heat, and smoke generated during a thermal runaway event.

Once sealed, the containment system restricts oxygen flow and prevents toxic fumes from spreading throughout the aircraft cabin. Proper sealing of the zipper and hook-and-loop seam is essential to maintain containment effectiveness.

Yes. HOT-STOP® ‘L’ containment bags are widely used by airlines, corporate flight departments, and other aviation operators as part of their lithium-ion battery fire mitigation procedures. They are designed to support onboard safety programs that address risks associated with portable electronic devices, such as large tablets and electronic flight bags (EFBs).

Yes. HOT-STOP® ‘L’ containment bags incorporate shielding materials designed to limit cellular and radio frequency signals from devices placed inside the bag. By preventing a damaged tablet from attempting to reconnect to wireless networks, this shielding can help reduce additional heat generation during a battery failure event.

Operators should regularly inspect the zipper teeth, zipper stitching, pull-tab strap, and outer fire-resistant shell for signs of wear, cuts, or abrasions. If any damage is discovered that could affect the bag’s sealing capability or structural integrity, the bag should be removed from service and returned for repair or replacement. Storage pouches and carrying components should also be checked for damage.

The containment bag is designed for quick and intuitive deployment during an emergency. However, operators are encouraged to review the manufacturer’s Standard Operating Procedures (SOP) videos and guidance materials.

Many aviation organizations incorporate HOT-STOP® ‘L’ deployment procedures into crew emergency equipment training programs to ensure personnel can respond quickly to lithium-ion battery incidents.

Maintenance requirements are minimal. Operators should perform routine visual inspections and occasionally lubricate the zipper with beeswax to ensure smooth operation. The bag should also be stored clean, dry, and unzipped so it remains ready for immediate deployment.

HOT-STOP® ‘L’ containment bags are designed for single-event use when deployed during an actual lithium-ion battery thermal runaway. After such an incident, the bag must be returned under the lifetime replacement warranty program. If the bag has not been used in an incident and remains undamaged, it may continue to remain in service or be used for training demonstrations.

The oversized tablet containment bag is commonly used in commercial, business, and military aviation, as well as other safety-critical environments where large lithium-powered devices are present. It is particularly useful for managing risks associated with oversized tablets, electronic flight bags, and other large portable electronics carried by crew members or passengers.

Because fire containment bags are typically classified as loose tools or onboard safety equipment, a Certificate of Conformance (CofC) is not normally required. However, a CofC can be issued upon request if an operator requires documentation for procurement records or internal compliance procedures.
