What is included in an airworthiness inspection? View PDF
1. Check Airtight Zipper Closer - Inspect zipper closure for any damage to teeth of zipper. If teeth have been damaged the bag will not close. *Send back for repairs.
2. Check Velcro Pull Tab Strap - If pull tab is missing, take kit out of service and replace pull tab strap.
3. Check Exterior Shell Material - Inspect for any wear areas that have penetrated the red outer cover. If an abrasion through outer material or a cut through the outer material, the kit must be taken out of service and returned for repairs
4. Check Zipper Stitching - If airtight zipper stitching is pulled, the kit must be taken out of service and returned for repairs.
5. Check Storage Bags and Strap Slings - If zipper chain is damaged or the storage strap stitching is pulled, the bag should be replaced.
6. Check Interior Fireproof Liner - Any damage to the interior fireproofing liner is extremely unlikely. Cuts or punctures to the interior would be cause to take the kit out of service and replace. 

Any kit deployed for an incident that does not progress to a thermal runaway would not be cause for removing from service. If no battery explosions or fires occurred within the bag, simply follow the standard inspection protocols and otherwise return to service. Damage to HOT-STOP L Kits shell and zipper closure are repairable. Contact Baker Aviation for repair costs and lead-times.

Why do fire containment bags exist?
Fire containment bags are commonly used on-board aircraft (business jets and on airlines) and in other confined spaces where there is a need to quickly contain a lithium-ion battery powered device during thermal runaway that can result in toxic smoke release and fire, with the possibility of an explosion. 
 
How does the HOT-STOP ‘L’ containment bag work? 
There are only Six Easy Steps to deployment.
1.  Remove Kit (bag, gloves) from storage bag or carry sling
2.  Donn safety gloves, and goggles, if available
3.  Place device into containment bag below the interior baffles
4.  Pull red tab marked “PULL” to expose hook & loop closure
5.  Press along seam to seal hook & loop closure
6.  Close zipper tightly against stopper to seal bag
 
Once properly deployed, the HOT-STOP® 'L' Fire Containment bag safely contains the fire, explosions, and 100% of all toxic smoke emissions from Lithium-Ion powered devices (tested up to 20,000 mAh – see chart below). There is no requirement to add water; however, HOT-STOP ‘L’ products allow the use of water so that airline operators and others can comply with SAFO FAA recommendations.
 
What types of battery powered devices does HOT-STOP ‘L’ contain?
HOT-STOP ‘L’ Kits accommodate and contains a multitude of devices, including defibrillators, laptops, tablets, all-in-one computers, mobile phones, portable chargers, battery packs/banks*, e-cigarettes, portable ELTs in aircraft, and more.
*check with a HOT-STOP ‘L’ associate as some high-capacity battery packs may require one of our custom solutions.
 
How do I know what size containment bag to purchase?
As the pioneer in fire containment technology, HOT-STOP ‘L’ kits come in multiples sizes to accommodate today’s evolving technology. Our expertise and extensive testing allow us to efficiently match the right size fire containment vessel to the devices you need to contain. Our customer service team will assist you in making this decision when you place your order.
 
How much do the bags weigh?
Standard HOT-STOP ‘L’ containment bags are approximately 1”- 2 ½” thick and weigh 2-8 lbs.
 
What is the average price of a fire containment bag?
Depending on the size required, HOT-STOP ‘L’ Fire Containment Kits range from $925 for the ELT/Phone design to $2850.00 for the largest and most popular solution, the 27” x 26” EVO XL bag.
 
How do I store the bags when not in use?
The HOT-STOP ‘L’ bags are easy to store in the cockpit or cabin. Pliable firefighting materials make the lightweight bag (4-8 lbs.) easy to fold and store in confined spaces.  It is important to always store the bag unzipped and ready to deploy in a convenient location.

What is the shelf life of the HOT-STOP ‘L’ bag?
Firefighting materials engineered into HOT-STOP ‘L’ products provide an unhindered shelf life and require minimal periodic maintenance that consists of visual inspection and zipper lubricant. 
 
What is the warranty?
The HOT-STOP ‘L’ manufacturer supports a lifetime replacement warranty if the bag is every deployed to contain a runaway device. Incident report with the used bag must be returned. Contact us for details at +1-214-957-6479.
​

What makes HOT-STOP ‘L’ better than competitor products?
The HOT-STOP® ’L’ product have achieved FIREPROOF status by an FAA-Registered laboratory and are made up of multiple durable fabrics with a felt inner core that has a 3200º F melting point. This core is sandwiched between two outer layers that have a 2080º F melting point and are proven to absorb energy and fire while the military grade zipper technology adds an airtight layer of protection by eliminating the escape of toxic smoke, gasses, carcinogens and other emissions. This designation sets HOT-STOP ‘L’ Kits apart from other products and assures customers that our containment solution has successfully completed the most rigorous testing to achieve FIREPROOF status and protect them from the real threat of lithium-ion battery fires.
 
Are HOT-STOP ‘L’ Kits Burn Certified?
Leading the way with independent testing, all HOT-STOP ‘L’ Kits are Burn Certified (bag, gloves, stowage bag individually burn certified) and tested at an FAA-Registered Laboratory. They have also received the ultimate FIREPROOF designation as defined by 14 CFR 1.1 with the FAA (AC20-135). 
 
What is mAh and should I care?
You may have seen electronic device descriptions, especially for power banks, that include a milliamp hour or mAh, and wondered what does this mean? As indicated in the chart below, the mAh determines the battery power and helps determine watt hours too, an important measure for airline carry-on limitations. As a universal unit of measure, mAh is also referenced in some lithium-battery fire containment testing.
 
At HOT-STOP ‘L’, we always want to help you choose the right fire containment bag size for the types of devices you are bringing on board the plane. In some cases, we custom design and test containment kits to accommodate higher mAh or watt hour ranges. See the typical mAh range below for common personal devices and contact us with any questions. 
Watt hours = (mAh x Voltage) / 1000
mAh = (Watt Hours x 1000) / Voltage


Standard nominal voltage for li-ion batteries is 3.7V but can be 6.5V or more
