Sector Overview

A system of prevention, preparedness, response, and recovery elements, the Emergency Services Sector (ESS) represents the nation's first line of defense in the prevention and mitigation of risk from both intentional and unintentional manmade incidents, as well as from natural disasters. The ESS also serves as the primary protector for the other 15 critical infrastructure sectors.

Encompassing a wide range of emergency response functions, the primary mission of the ESS is to:

• Save lives

• Protect property and the environment

• Assist communities impacted by disasters

• Aid in recovery from emergencies

These functions, the majority of which are performed at the state, local, tribal, and territorial levels, are defined by five disciplines:

• Law Enforcement

• Fire and Emergency Services

• Emergency Management

• Emergency Medical Services

• Public Works

Additionally, there are several specialized capabilities identified within the ESS, such as:

• Hazardous Materials

• Search and Rescue

• Hazardous Devices Team/Public Safety Bomb Disposal

• Tactical Teams (i.e., SWAT)

• Aviation Units (i.e., police and medevac helicopters)

• Public Safety Answering Points (i.e., 9-1-1 call centers)
