Purpose: The purpose of this SOG is to create a uniform procedure regarding the

Two In / Two Out policy

Policy: When in IDLH atmospheres, “the two in two out” rule will apply.

Definitions:

Area of Immediate Danger to Life and Health (IDLH)

Structural: The area immediately inside the structure involved.

All personnel responding to potential or existing IDLH situations must be dressed in full PPE, to include SCBA.

All personnel working inside an IDLH must operate in teams of at least two fire fighters. Personnel in each team must maintain voice or visual contact with each other while operating in the IDLH. Using radios as the sole means of contact between members of a team is not permissible.

Two fire fighters in full PPE must be assigned outside the IDLH to serve as a rapid intervention team (RIT), prepared to rescue fire fighters if necessary. A charged hose line and RIT Pack, as well as a set of Irons are required.

Only fire fighter 1 or higher-level fire fighters may be assigned to the RIT.

Deviations from this SOG may only be made during a rescue situation with a known human life-hazard, not including standard search and rescue activities.

Rescue Situation: A known rescue situation is one where there is a compelling factor beyond a reasonable doubt to start an interior rescue before all required personnel have arrived on scene.
