ready for hose connection and Made by Interspiro (previously known as AGA); the inventors of Positive Pressure Breathing Apparatus; there are no simpler, safer escape sets than Spiroscape, short duration breathing apparatus (SDBA) .
Quickly and simply donned; the user can focus on safe egress and escape: without fuss; without delay and with very easy training and practise (both of which are required by UK Regulation).
Such efficiency is enhanced; for example; by the unique ambient air valve, which automatically opens when the cylinder is depleted; thereby eliminating risk of subsequent anoxia, inside the hood.
The Patent air distribution system expels expired CO2, reducing relative breathing rates and so optimizing the use of cylinder air.
