Firefighters work in a toxic environment and the device which they have to carry is Self-Contained Breathing Apparatus (SCBA). This device works for 30 minutes only and weighs about 15 kg.

NanoGen is a concept device that filters toxic gases from uncontrolled fires with the help of nano fiber PAN technology. Polyacrylonitrile (PAN) nanofibers as a precursor of carbon nanofibers with diameters in the range of 130–280 nm that are obtained by electrospinning of PAN solution. This device filters two main toxin gases which are found in fires, Hydrogen cyanide (HCN) and Carbon Monoxide (CO).

There is also an emergency cylinder that weighs much less. This cylinder contains compressed oxygen which firefighters can use in case of any emergency. This also improves their flexibility in movement.

Designed by Ashrutha Alagani and Jaya Vikash, The helmet of NanoGen helps firefighters to circulate air within the helmet and prevent toxic gases to enter inside. The partition in the helmet allows circulation of air within the lower area itself so that the purified air can be taken in effectively. The transparent part of the helmet helps firefighters to communicate better with the victims, providing comfort and reassurance through their facial expressions.

Another reason for this helmet is designed with transparent material is because, most often than not, victims are too scared and traumatized during the accident. When firefighters enter the room with a full face cover, it won’t create effective communication. We wanted the victims to feel connected and safe when they see a firefighter.

Tuvie has received “NanoGen Breathing Device” project from our ‘Submit A Design‘ feature, where we welcome our readers to submit their design/concept for publication.
