Which channels should an IC scan when personnel are in an IDLH environment?

In an Incident Command (IC) situation where personnel are operating in an Immediately Dangerous to Life and Health (IDLH) environment, it is crucial to maintain clear and swift communication to ensure the safety of all team members. The channels that an IC should scan are typically those that are designated for command and tactical operations, as well as emergency communications.

Using "Command" allows the IC to maintain overall situational awareness and strategic direction, ensuring that all personnel are informed about the incident's status and objectives. The "Tactical" channel is essential for direct communication with teams operating on the ground or engaging in specific firefighting or rescue tasks, allowing for immediate instructions or updates as conditions evolve. Finally, scanning the "Emergency" channel is critical since it is used for urgent communications regarding immediate threats to personnel's safety and requires urgent actions or alerts.

Choosing these three channels ensures that the IC can effectively manage resources, address emergencies as they arise, and keep personnel in IDLH environments informed, all of which are vital for maintaining safety and operational effectiveness in high-risk situations.
