Fire Escape Solutions, like the Dräger PARAT 5500, allow the firefighter and the victim to move independently from one another – unlike the Dräger PSS Rescue Hood, where a physical connection is required. To prevent any harm from toxic gases and substances, these devices have an integrated gas and particle filter, which filter the harmful substances out of the ambient air. The device protects the victim for a minimum of 15 minutes. A filtering escape hood does not affect the firefighter’s air supply or operational time. But it relies on sufficient oxygen in the ambient air, which is normally no problem – because where there’s fire, there’s oxygen.
