Study Notes

Initial Response and Risk Assessment

The first arriving officer should evaluate the situation to determine the best course of action.
Risk/benefit analysis should be assessed to determine the potential risks and benefits of different actions.

Defensive Attack Strategies

During the transition from offensive to defensive attack, it is essential to have a clear understanding of the situation and to prioritize safety.
Defensive attacks are primarily used to protect exposures and prevent fire spread.
The primary consideration for conducting defensive attacks is to protect people and property.
The recommended tactic for protecting internal exposures in defensive mode is to use a remotely operated monitor or a large-caliber hose stream.

Water Application and Stream Placement

The energy levels for radiant heat depend on the distance from the fire and the size of the flames.
Applying water directly on exposed structures is considered the best tactic when the fire is not too large and the structure is not too heavily involved.
The primary consideration in placing exterior streams is to take into account the wind direction, flame height, and location of the fire.

Conflagration Response and Strategy

A conflagration in an urban setting refers to a large, uncontrolled fire that spreads quickly from building to building.
Common contributing factors in urban conflagrations include strong winds, dry conditions, and closely spaced buildings.
The primary means of fire extension from building to building as the flame front widens is through radiant heat and embers.
The fire department is typically the best agency to manage the evacuation during a conflagration.
The first step in developing a conflagration strategy is to identify potential fire spread routes and prioritize resource allocation.

Property Conservation and Overhaul

Nonattack postures are often underused due to the potential for property damage.
The primary damage in a fire is usually caused by water and smoke.
Property conservation is generally considered no longer an issue when the fire is under control and the structure is safe to enter.
The proper application of larger-than-needed hose streams can increase water damage.
A recommended action to reduce water damage is to use a smaller hose stream and to apply water only where necessary.
Removing a toilet can create a pathway for water to flow into adjacent areas.
Before sending personnel into a confined space containing standing water, it should be ensured that the water is safe to enter and that the necessary precautions are taken.
The purpose of overhaul in firefighting is to search for and extinguish any remaining hotspots or hidden fires.
