The potential dangers of lithium-ion batteries

It's something all of us use every day yet very few are aware of the potential dangers - especially on board an aircraft.

All our technical gadgets from mobile phones to tablets and laptops are powered by rechargeable lithium-ion batteries. There is always a possibility they can overheat or catch fire if they are mishandled or damaged. And that can pose a big problem on board aircraft where there will be dozens, if not hundreds of electronic gadgets, which is why the AvSax fire containment bag for aircraft has been invented.

Some of these batteries have burst into flames, potentially posing a serious threat to aircraft safety, but AvSax fire containment bags can significantly reduce that danger in seconds. Simply pour in at least 2 litres of water and pop the suspect device into the AvSax bag. The fire mitigation bag's polymer gel inside expands to totally surround the device, instantly cooling it down to minimise the risk by adding further water. If it should still vent, the polymer is designed to absorb the force.

Why AvSax are needed

Watch the videos to see why AvSax fire mitigation bags are so important in today's technology-focused world and find out how they work.

 As shown on BBC Look North...



AvSax fire containment bags are innovative heatproof bags specially designed for emergencies.
