The Incident Commander or Unified Command determines the kinds and locations of ICS facilities based on what is required to support the incident.

The Incident Commander or Unified Command may establish several different kinds of facilities in and around the incident area.

Common ICS facilities:

• The Incident Command Post (ICP) - location of the tactical-level, on-scene incident management (Incident Commander or Unified Command and Staff)
• Staging Areas - temporarily position and account for personnel, supplies, and equipment awaiting assignment
• Incident Base - location at which personnel conduct primary support activities (may be co-located with the ICP)
• Camps - satellites to an Incident Base, established where they can best support incident operations by providing food, sleeping areas, sanitation and minor maintenance and servicing of equipment
