For the longest time firefighters had to fight to be given portable radios while on the fire ground. SO today’s drill ask you, do you know how to fully use your radio? Can you switch to the different zones, and use the different functions it has? Can you activate your emergency escape button or change channels with a gloved hand? All of these are taken lightly but it is not funny when your asked to be on a channel and you did not know it was there, let alone know how to change to it. Also read through your policy on radio communications. If you think of any other drills post them here.
