The SCape CBRN30 Respirator is comprised of a protective hood with integrated visor, a one-size-fits-all neck seal, a CBRN canister, and a blower which provides filtered air.  An integral blower, which automatically turns on upon removal of the hood from the container, provides up to 30 minutes of filtered breathing air for the wearer.  This example was made by ILC Dover in 2015.
