Private security fits into the big picture. Standardization is helpful in communicating and taking action.  The Five Mission Areas of Federal Emergency Management Administration- FEMA are a national level concept in responding to emergencies.  At a large or individual level the Five Mission Areas help us visualize how to respond to a dangerous situation.  It is also likely that a security officer will be involved in a situation where government responders are involved. All security professionals should have a knowledge of Federal Government concepts in security and safety.
