This protective smoke hood, specially designed for cabin crew, uses compressed aeronautical quality oxygen and delivers this oxygen to commercial flight crewmembers, as soon as it is put on, for 15 minutes of operating time. The Air Liquide PN 1540F-11 hood is protective breathing equipment specially designed for flight crewmembers so that they can move about in a polluted atmosphere (smoke on board, smoke coming from outside during evacuation, fire in the cabin, cabin contaminated by toxic fumes, etc.).
Its original design ensures that no adjustments need to be made to an oro-nasal mask and gives precious extra seconds in operational circumstances. Fewer than 8 seconds are required to take the hood out of its box, rip open its sealed cover and put it over the head. The hood does not need to be adjusted once it is put on. This single size equipment adapts to all face configurations.
The equipment is self-sufficient and operates as a closed circuit. As soon as it is put on, it automatically delivers oxygen. It neutralizes the CO2 breathed out (soda lime cartridge) and guarantees the user 15 minutes of operating time. A speech diaphragm facilitates communication with all available on board resources. The hood is also certified to protect against hypoxia (holding Civil Aviation Qualification QAC168), up to 25000 ft.
The hood is made of Nomex fabric which provides optimum protection in the event of fire. The polycarbonate visor treated with an anti-fog and anti-scratching coating provides unparalleled visibility.
