Margo (not her real name) got me a cool fire helmet with this thing on it that has lights, a siren, and and an amplifier to talk through while giving evacuation orders.
I had to surgically remove the electronics from the mask as it crushed my face with the mask down. It is now safely separated as a hand-held unit that I have attached to a lanyard.
Thanks Margo (not her real name). We all feel safer now.
