10-80 signals that a vehicle pursuit is underway. This alerts nearby units to be on guard for high-speed operations. It helps coordinate backup and safety measures.
Which EMS priority is appropriate for an unresponsive patient not breathing?
Priority 1 (immediate response)
Priority 2 (urgent, no lights)
Priority 3 (non-urgent)
Priority 4 (referral or non-transport)
Priority 1 is reserved for life-threatening situations needing immediate response, such as an unresponsive patient not breathing. It mandates lights and siren transport. Early arrival can be critical to survival.
A patient with chest pain but stable vital signs typically receives which EMS priority?
Priority 2 (urgent, no lights and siren)
Priority 1 (immediate response with lights)
Priority 3 (non-urgent)
Priority 4 (no transport needed)
Priority 2 is used for serious but non - life-threatening conditions, like stable chest pain. It prompts a quick response without emergency signals. This balances urgency with safety.
Which EMS priority covers minor injuries where transport is still required?
Priority 3 (non-urgent transport)
Priority 1 (immediate life threat)
Priority 2 (urgent no lights)
Priority 4 (no transport)
Priority 3 applies to non-urgent cases that still need transport, such as minor soft-tissue injuries. It usually involves normal driving with no lights or siren. This scheduling helps resource management.
What is the key difference between Code 2 and Code 3 dispatch responses?
Code 2 uses no lights or siren, Code 3 uses both for emergency transport
Code 2 is for major crimes, Code 3 is for minor tasks
Code 2 is clear scene, Code 3 means suspect in custody
Code 2 signals medical emergency, Code 3 signals hazmat
Code 2 indicates an urgent response without lights or siren, while Code 3 mandates lights and siren for emergency. Understanding this distinction prevents inappropriate use of emergency signals. It also helps maintain public safety.
If dispatch instructs an officer to 'Proceed Code 2', how should the officer respond?
Respond promptly without using lights or siren
Stop all transmissions and hold position
Proceed with lights and siren immediately
Return to station
Proceeding Code 2 means to respond quickly but without activating lights or siren. It indicates moderate urgency. This protocol helps balance response speed with roadway safety.
In mass casualty incidents (MCI), which level generally indicates more than 25 patients requiring triage?
Level 3
Level 1
Level 2
Level 4
MCI Level 3 usually signifies a large-scale incident with over 25 casualties. It requires extensive mutual aid and resource coordination. Accurate level assignment ensures the right response scale.
What action should units take when dispatch broadcasts code 10-33?
Cease non-emergency radio traffic and await instructions
Immediately respond with lights and siren
Proceed to the hospital
Begin evacuation procedures
10-33 is used to clear the airwaves for an urgent announcement from dispatch. Units should hold all non-critical communications. This preserves channel clarity for critical information.
What is a primary benefit of using standardized dispatch codes like 10-codes?
They allow concise, clear communication under stress
They provide legal authorization for arrests
They enable unlimited private messaging
They replace all verbal communication
Standardized codes reduce radio traffic and ensure clarity, especially under high-stress conditions. They minimize misunderstandings and speed up dispatch operations. This consistency benefits multi-agency responses.
In hazardous materials response, which zone is designated for incident command and support functions?
Cold Zone
Warm Zone
Hot Zone
Blue Zone
The Cold Zone is the safe area for command, logistics, and medical support in a hazmat incident. It is free from contamination and typically houses incident command posts. Proper zone designation protects personnel and resources.
In fire department dispatch, what does a 'Box Alarm' typically signify?
A prearranged assignment of multiple fire units to a structural fire
Notification that the fire is under control
Cancellation of all incoming units
Hazardous materials team activation only
A Box Alarm dispatches a predetermined combination of engines, trucks, and command officers to a structural fire. It streamlines resource deployment for building fires. This system speeds up initial containment efforts.
