Study Notes

Incident Communications Policy

The purpose of this policy is to standardize incident communications for Montgomery County Fire and Rescue Service (MCFRS) personnel.

Definitions

Critical terms and their corresponding actions are defined in Appendix Q.

Radio Communications

The MCFRS radio system is the primary tool for incident communications.
Efficient communications use all available pathways, including radio traffic, body language, face-to-face communication, and other signals.

Radio Returns

A radio return is a short transmission providing an update on the incident status.
The Incident Commander must provide a radio return when placing units in service for complex incidents.

LCAN Reports

Location, Conditions, Actions, Needs (LCAN) reports are used to provide situational awareness.
The Incident Commander must use the LCAN format when providing an update.

Evacuations

"Evacuate" is used to identify imminent danger to life or health, requiring immediate evacuation of personnel.
When an evacuation order is given, personnel must leave the hazard area without delay or negotiation.
An evacuation order is also an order for radio silence.

Personnel Accountability Report (PAR)

A PAR is conducted to ensure personnel accountability, especially in IDLH environments.
The PAR is typically conducted at 20-minute intervals and includes all personnel operating in the hazard area.
The Incident Commander must provide a verbal warning before conducting a PAR.

SIGNAL3

SIGNAL3 is used to indicate immediate danger to personnel, requiring an emergency response.
The term is only used when personnel are in danger and cannot escape.
The use of SIGNAL3 generates an emergency response from command officers and the police.

Mayday

Mayday is a distress signal used in structural firefighting operations to indicate immediate danger.
The term is used to announce that a responder is in need of assistance and cannot escape.

Priority Messages

Priority messages are used for situations where unacknowledged transmissions may result in severe harm or adverse incident outcomes.
When a priority message is transmitted, radio silence is in effect until the Incident Commander acknowledges the message.

Radio Silence

Radio silence is used to limit radio communications during critical incidents.
Personnel must not talk on the tactical talkgroup unless they have an emergency, priority message, or are called for.

Unacknowledged Transmissions

When a priority, SIGNAL3, or Mayday message is unacknowledged, all personnel are empowered to notify Command or ECC of the message.
