Emergency Facilities used for Mutual Aid
Incoming mutual aid resources may be received and processed at several types of
facilities including: marshalling areas, mobilization centers, and incident facilities. Each
type of facility is described briefly below:
Marshalling Area: Defined in the Federal Response Plan as an area used for the
complete assemblage of personnel and other resources prior to their being sent directly
to the disaster area. Marshalling areas may be established in other states for a
catastrophic California earthquake.
Mobilization Center: Off-site location at which emergency services personnel and
equipment are temporarily located pending assignment, release, or reassignment. For
major area-wide disasters, mobilization centers maybe located in or on the periphery of
the disaster area.
Incident Facilities: Incoming resources may be sent to staging areas, other incident
facilities, or directly to an incident depending on the circumstances. Staging areas are
temporary locations at an incident where personnel and equipment are kept while
awaiting tactical assignments. Incident facilities are discussed further in section I.B.
6. Overview of SEMS Response
The following describes generally how SEMS is intended to work for various emergency
situations. The situations are described in terms of the involvement and interactions of
the five SEMS levels, and are intended to apply to all types of disasters that may occur
in California, such as, earthquakes, floods, fires, and hazardous materials incidents. Not
all possible situations and interactions are described.
This discussion assumes that appropriate emergency declarations and proclamations
are made. It also assumes that multi-agency or inter-agency coordination is
accomplished at each level by SEMS regulations. The responses at each level are
discussed in more detail in sections I.B. through I.F. of the guidelines. Note that SEMS
may be activated and resources mobilized in anticipation of possible disasters. Such
anticipatory actions may be taken when there are flood watches, severe weather,
earthquake advisories, or other circumstances that indicate the increased likelihood of a
disaster that may require emergency response and mutual aid. The extent of actions
taken will be decided at the time based on the circumstances.
Local Incident within Capability of Local Government
• Field Response: Field units respond as needed using the Incident Command
System. Resources are requested through local government dispatch centers.
