Firefighting techniques are specialized methods used by firefighters to extinguish fires, rescue people and property, and limit the spread of fire. These techniques are based on an understanding of fire dynamics, the behavior of different types of fires, and the properties of various firefighting agents. Here are some common firefighting techniques:

1. **Direct Attack**: This involves applying water or another extinguishing agent directly onto the fire to cool it, displace oxygen, or break the chemical chain reaction of combustion.

2. **Backdraft Prevention**: A backdraft occurs when a fire consumes oxygen in a confined space and fresh air is introduced, causing a rapid and intense combustion. Firefighters use techniques to recognize the potential for a backdraft and to ventilate the area safely to prevent it.

3. **Ventilation Control**: Controlled ventilation can be used to remove smoke and heat from a structure, but it must be done carefully to avoid introducing additional oxygen to the fire, which could cause a flashover.

4. **Flashover Prevention**: A flashover is the near-simultaneous ignition of most of the directly exposed combustible materials in an enclosure. Firefighters work to prevent flashover by cooling the fire, removing heat, or interrupting the fire's fuel supply.

5. **Fire Stream Management**: This involves the strategic use of water or other extinguishing agents, including the selection of the appropriate nozzle, hose size, and water pressure to effectively combat the fire.

6. **Search and Rescue**: Firefighters use systematic search patterns to locate and rescue trapped individuals, often in smoky or low-visibility conditions.

7. **Salvage and Overhaul**: After the fire is extinguished, firefighters work to salvage property and overhaul the fire scene to ensure that all hidden fire extensions are extinguished.

8. **Use of Personal Protective Equipment (PPE)**: Firefighters wear specialized gear, including helmets, fire-resistant clothing, gloves, boots, and breathing apparatus, to protect themselves from the heat, smoke, and other hazards.

9. **Rapid Intervention Teams (RIT)**: These teams are ready to rescue firefighters who may become trapped or injured while fighting a fire.

10. **High-Rise Firefighting**: Special techniques and equipment are used to fight fires in high-rise buildings, including standpipes, elevators (when safe to do so), and high-reach extendable ladders.

11. **Wildland Firefighting**: Techniques used in wildland firefighting include controlled burns (backfires and burnouts) to remove fuel in the path of a wildfire, as well as the use of firebreaks and water-dropping aircraft.

12. **Hazardous Materials (Hazmat) Response**: Firefighters trained in Hazmat response use specialized techniques and equipment to handle incidents involving hazardous materials, including chemical spills, gas leaks, and other dangerous substances.

Firefighting is a dynamic and evolving field, with ongoing research and training to improve techniques and safety. Firefighters must be adaptable and able to make quick decisions based on the conditions they encounter at each fire scene.
