If you are using the TIC in an internal search, it is best to commit a 3 man team. The team leader obviously leads the team and ensures the personal protection of the team, the second firefighter will have the TIC and carry out regular sweeps of the area (for casulaties, hot spots etc) and the third team member will take up the rear of the group, again providing protection for the TIC user. But its worth bearing in mind that the TIC is just a tool to be used along with everything else, and should not be totally relied upon or substituted for traditional methods, only used as an asset to them.
As Peter said, you can use the TIC for a multitude of incidents, not just internal fires. I've seen it used at an RTA to search for a casualty who had been thrown from a vehicle.
