A terrorism incident is high profile and involves multiple responders, agencies, resources and equipment. Unsolicited responders and volunteers are commonplace and will need to be organized, supervised, vetted and tracked. Convergent unsolicited volunteers may consume and utilize human and logistical resources and can pose a risk to themselves and others if they are not vetted, registered and considered in operational preplanning.
The response duration of rescue and recovery may have an extended duration exhausting human and mechanical resources requiring planning for rest, rehabilitation, replacement and recovery.
Mutual aid agreements will be necessary with drills to test the capability of multiple agencies to work and communicate in a coordinated manner in an otherwise unpredictable and chaotic situation.
