Study Notes

Tactical Worksheet and Incident Command

Initiate a tactical worksheet to ensure all tactical issues are addressed effectively.
Diagram incidents with available resources for clear situational awareness.
Assign an acting company officer equipped with a portable radio for fire suppression or emergency action.
Remaining company members follow the acting company officer once assigned by the initial Incident Commander (IC).

Functions of Command

Immediate command functions include determining strategy, selecting tactics, and establishing the Incident Action Plan (IAP) during size-up and initial actions.
Initial radio reports cover critical operational information and may be dictated by Standard Operating Procedures (SOPs).

Resource Management

Develop the ICS organization, manage resources, coordinate activities, and ensure scene safety.
The safety officer should be designated as necessary to maintain firefighter accountability and the rapid intervention resources in Immediately Dangerous to Life or Health (IDLH) environments.

Evolution of Fire Dynamics

Modern fires are characterized as ventilation-limited, contrasting with earlier fuel-limited fires.
The 1908 ASTM fire experiments provided the foundation for time-temperature curves applicable to structural firefighting.
Research, like the 2012 Governor's Island experiments, emphasizes controlling access doors to minimize air introduction, which can delay flashover.

Firefighter Risk Management

Operations in flow paths increase risk due to fire, heat, and smoke movement.
Limiting flow paths until water application is ready is crucial for risk reduction.

Characteristics of Modern Structures

Differences in building factors include larger sizes, open geometries, increased fuel loads, and new construction materials.
UL studies noted a dramatic reduction in time for effective suppression of modern single-family dwelling fires.

Tactical Priorities and Incident Management

Incident management prioritizes life safety, incident stabilization, and property conservation.
Tactical priorities include RECEO-VS: Rescue, Exposure protection, Confinement, Extinguishment, Overhaul, Ventilation, and Salvage.

Size-Up and Strategic Decision Making

Size-up involves gathering and analyzing information to develop the IAP and necessitates comprehensive site evaluation using thermal imaging and other methods.
Control of ventilation and flow paths is vital in ventilation-limited fires to protect occupants and reduce fire growth.

Fire Suppression Techniques

Effective water application within 30-60 seconds drastically impacts fire conditions and outcomes.
Extinguishment must be thorough, including overhaul in void spaces, once safety conditions are assessed.

Incident Command Structure

The exterior of buildings is designated with sides A-D, following a clockwise order.
Companies are assigned divisions based on the structure's layout for effective management.

Tactical Safety Considerations

Safety hazards persist despite advancements; after command transfer, the incoming IC assigns appropriate roles for ongoing management.
The ICS should be utilized consistently in all events for effective coordination and safety management.

Summary of Incident Command Responsibilities

Fire officers must establish command, manage incidents, and supervise their teams effectively according to national frameworks like the NIMS.
The first-arriving officer is responsible for establishing command and addressing strategic priorities: life safety, incident stabilization, and property conservation.
Command structures should include strategic, tactical, and task levels for comprehensive incident management.
