One of the biggest challenges faced by an incident commander during a large scale event is going to be communications. The large scale incidents will bring together many of your mutual aid partners along with other local, county, state and federal agencies. It is neither necessary nor practical to be able to have all these agencies on a common communications frequency but the ability for everyone to share information is very important. The incident commander may not want all these agencies setting up camp at the incident and may be better coordinated with them operating out of the local EOC. At the EOC much of the communications between agencies can be done face to face or during small group meetings to share information and coordinate planning for the future of the operations.
