Small aircraft and helicopter companies now using AvSax battery fire containment bags to deal with lithium battery fires 

Small airline and helicopter companies are using the award-winning AvSax fire containment bag to deal with potentially catastrophic lithium battery fires on board. 

Passengers bring personal electronic devices (PEDs) on board including laptops, mobile phones and laptops but all are powered by lithium battery fires which can potentially catch fire. 

The last thing airline and helicopter companies want is an uncontrollable toxic fire in flight which could have terrible consequences. 

Lithium batteries burn at far higher temperatures than normal fires which is why a special AvSax battery fire mitigation bag is needed to contain them. 

If lithium-ion batteries overheat or catch fire they go into what’s known as thermal runaway. This happens when one cell in a battery overheats it can produce enough heat – up to 900°C (1652°F) – to cause adjacent cells to overheat. This can cause a lithium battery fire to flare repeatedly. 

The award-winning AvSax covers the airline or helicopter company’s duty of care and responsibility to passengers as carrying one on board means the crew is: 

* Able to hold an electronic device in a bag that is so resilient it can contain the force of the device going into full thermal runaway. 

* Reduce the chance of catastrophic damage to the aircraft. 

* Reduce the risk of toxic smoke in the cabin which would be highly dangerous to both passengers and crew. 

* Means that the flight probably won’t need to be diverted. Aircraft that have deployed AvSax lithium battery fire containment bags in action have never had to divert. 

AvSax are made from military-grade material which means that if the device bursts into flames it’s contained within the bag. They can even withstand the force of a battery charger exploding in them – containing the heat, blast and debris. 

The Federal Aviation Administration in the USA and the Civil Aviation Authority in the UK have clear rules on how lithium batteries should be taken on board aircraft. Read all about them at

AvSax managing director Richard Bailey said: “The pandemic has taken a massive toll on airlines worldwide but we are now beginning to see the start of the recovery and here at AvSax there has been a noticeable increase in inquiries over the last few weeks, especially from smaller airline companies and helicopter operators.

“We realise this is a tough time for the industry so we are doing what we can to help by offering AvSax at a discounted price at the moment.”

AvSax are the world’s best-selling fire containment bag for PEDs on aircraft and are now on more than 15,373 aircraft operated by 80 airline companies. They have been used 33 times to deal with emergencies since the start of 2017 and every time they have been deployed the aircraft has been able to complete its journey safely with no need to divert or make an emergency landing.

AvSax won the prestigious Queen’s Award for Enterprise in the UK in 2018.
