Interspiro Spiroscape Emergency Escape Breathing Device (EEBD), 15 minutes, 200 bar, 3 L cylinder is used to escape from smoke-filled or toxic environments. It is commonly used on board ships and in industrial facilities and can be used as rescue equipment in official buildings. Once it is donned, the user is able to focus on escape. This is made possible with the unique ambient air valve which automatically opens when the cylinder is empty. This function eliminates the risk of suffocation inside the hood and no air is wasted on a low air warning alarm.
