Perfectly

_____ Zone: This is the area of contamination. Only personnel w/appropriate high-level Personal Protective Equipment (PPE) are allowed. Activities are limited to essential rescue and containment efforts.

Hot Zone (Red Zone)

_____ Zone: Also known as contamination reduction zone; surrounds hot zone. Personnel must wear appropriate protective gear. Decontamination of patients and EMS personnel occurs here. It acts as a buffer to prevent the spread of contamination.

Warm Zone (Yellow Zone)

Cold Zone

_____: Occurs early in the incident upon first contact with patients. Involves quickly categorizing pt based on severity of injuries to determine immediate care needs.

Secondary Triage

_____ are set up based on the triage categories (immediate, delayed, minimal, and expectant). These areas are typically located in a safe zone away from the immediate hazards of the incident.

Treatment areas

_____: Established by the first-arriving public safety unit. The IC is responsible for scene size-up, resource management, and coordination of all response activities. Positioned in a safe location, often referred to as the Cold Zone, where they can effectively manage the incident without being exposed to hazards.

Incident Command

_____ Command: Involves single person who is highest-ranking official & has full authority over incident. Typically used in small-scale incidents with limited jurisdictional issues. Example: A traffic collision where the local fire department assumes overall command, coordinating with EMS and police.

Singular Command

_____ Command: Involves managers from multiple agencies & jurisdictions sharing command responsibilities. Necessary for complex incidents with overlapping responsibilities or jurisdictions. Example: Large-scale incidents like terrorist attacks, natural disasters, or hostage situations where law enforcement, fire, and EMS coordinate together.

Disaster

_____ Ambulances: Typically stationed at fixed locations, such as fire stations or hospitals, Deployment is based on historical data & anticipated call volumes, ensuring coverage across the community.

Regular Ambulance

_____ Ambulances: These are additional ambulances deployed during times of high call volume, known as peak load times. They are part of dynamic deployment strategies, which involve relocating ambulances to different locations throughout the day based on real-time data and projected needs.
