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

For proper readiness, the HOT-STOP® ‘L’ 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 tablet or iPad.

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 or iPad 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 fully 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 demonstrates the manufacturer’s confidence in the bag’s fire containment performance.

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

These tests verify 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 reviews or compliance audits.

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

Once sealed, the containment system restricts oxygen exposure and prevents toxic fumes from spreading inside the aircraft cabin. Proper closure 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, business aviation operators, and flight departments as part of their lithium-ion battery safety programs. They are particularly useful for managing incidents involving tablets and iPads used as electronic flight bags (EFBs) or cabin devices.

Yes. HOT-STOP® ‘L’ containment bags incorporate shielding materials that help limit cellular and radio frequency signals from devices placed inside the bag. This feature helps prevent a damaged tablet from attempting to reconnect to wireless networks, which can generate additional heat during a battery failure event.

Operators should periodically 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 found that could affect the bag’s sealing ability or structural integrity, the bag should be removed from service and returned for repair or replacement. Storage pouches and carrying components should also be inspected.

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 include HOT-STOP® ‘L’ deployment procedures in crew emergency equipment training programs so personnel can respond quickly during a lithium-ion battery incident.

Maintenance requirements are minimal. Operators should conduct routine visual inspections and occasionally lubricate the zipper with beeswax to maintain 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 tablet containment bag is commonly used in commercial, business, and military aviation, as well as other safety-sensitive environments where tablets or electronic flight bags are used. It helps flight crews and operators manage the risks posed by lithium-ion batteries in tablets carried by pilots, crew members, or passengers.

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