How many VHF's does your appliance carry?
Every truck I've ever worked off has *atleast* a hoseline and the OIC as a bare minimum.
Who on earth is letting crews go internal without atleast a single VHF between a pair of operators? That is grossly incompetent.
Its always been the case when I've gotten off an appliance to have a VHF in my hand, so the BA set goes on, and the VHF gets slung on the left hand shoulder strap, with the mic optionally being slung around the neck and clipped to the mic holder below your chin on the PBI.
If everything goes pear shaped how on earth are you meant to communicate to external crews? You can't ventilate, give sitreps or do hardly anything internally without a radio.
Are you sure its commonplace in CFS or just in your brigade?
