Early in my fire service career I spent some time with Tufts University in Boston MA. I was their Safety Specialist and later became the Assistant Fire Marshal. I was responsible for many of the emergency plans for a university with 3 campus. Communications was always an issue ! How do you keep people informed as to events, especially emergency events over a large geographical area? Radios were always the first line of communications for the public safety officers and each campus operated on their own frequency with no common talk around channel.
