Study Notes
Firefighting Operations
- Defensive firefighting operations are conducted from the exterior of the building.
- Offensive operations take place inside the fire building.
SLICERS Acronym
- In SLICERS, C stands for "Cool the space from the safest location."
- E stands for "Extinguish the fire."
Fire Attack Techniques
- A combination fire attack begins with an indirect attack.
- A defensive attack is utilized primarily to protect exposures.
- A direct attack involves applying water until all visible flames are extinguished.
Equipment and Techniques
- Master stream devices include portable monitors, deck guns, and ladder pipes.
- Firefighters should approach a vehicle fire from a 45-degree angle to minimize risk.
- A straight stream has the advantage of longer reach over a fog stream.
Specific Situations and Hazards
- Use of master streams is prohibited when crews are working inside a building.
- Bleve refers to the rupture and explosion of a flammable liquid vessel due to external heating.
- High-voltage components are a unique hazard in hybrid vehicles.
- Components containing pressurized gas present the greatest risk for fire in modern vehicles.
- Sulfuric acid is commonly found in vehicle batteries.
Indicators of Fire
- Peeling or bubbling paint indicates the presence of a concealed fire.
- For structures without doors or windows, a defensive fire attack should be employed if there are no life-safety hazards.
Safety and Emergency Management
- The flow path is the primary factor influencing fire movement through a structure, as determined by studies from NIST and UL.
- Streams should be directed at the area where a tank is being heated to prevent a BLEVE.
- Class C extinguishing agents are necessary for fires involving electrical equipment.
- To stop gas flow from a utility pipeline into a building, turn off the valve at the meter.
Thermal Dynamics
- An indirect attack occurs when water is directed at the ceiling from a doorway, aimed at cooling the upper part of the room.
- Fog streams are most likely to disrupt thermal balance within a fire environment.
