There are hundreds of potential fire risks among the electronic gadgets people take on board aircraft. Planes carrying 100 passengers could have around 500 lithium batteries when you tot up all the laptops, cameras, e-readers, tablet computers and mobile phones… and they pose a potential fire danger.
All are powered by rechargeable lithium-ion batteries but there is always a possibility they can overheat, causing the device to catch fire. This is known as thermal runaway, a rapid, uncontrolled chemical reaction within the battery that causes the internal temperature to rise. 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. That’s why AvSax is now carried on all major airlines in America and Europe.
How they work
Simply pour a minimum of two liters of water into an AvSax and then drop the device into the bag, adding additional water as required. The water activates the polymer gel inside the bag, causing it to expand around the device. The AvSax cools the batteries in the device, reducing the likelihood of the battery catching fire but if it does go into what is known as thermal runaway it is all contained within the bag. Amazingly the water is absorbed into the internal lining of the bag so the device is dry when it is removed.
AvSax are a lightweight vacuum packed device designed to mitigate devices that are going into thermal runaway, low-level blast, fragmentation and fireball containment. AvSax has undergone extensive testing and utilise the patented BlastSax Technology.
The AvSax is manufactured utilizing two patented BlastSax which are sewn together to make an inner sleeve. The inner BlastSax are then Hi frequency welded into a water resistant, flame retardant outer case.
