The most common emergencies are activated at level one. Services are usually provided at or near the site of the incident and may be delivered by one to two ESS team members designated by the local authority. The following organization chart shows a level one ESS response structure with functions that can be activated to assist evacuees. Keep in mind that only one or two responders are needed for all of the functions that are activated during a level one response.
If you are involved in level one ESS responses, more details about a level one ESS response can be found in a course called EMRG-1607 Level One ESS, offered at the JIBC.
