Study Notes
Fire Tetrahedron Components
- Fire tetrahedron includes heat, fuel, oxygen, and a chemical chain reaction.
Classes of Fires
- Fires are classified into four categories: Alpha, Bravo, Charlie, and Delta.
Class Alpha Fire Characteristics
- Produces white smoke.
- Caused by household goods and materials that produce ashes.
- Extinguishing agents include Firemain and CO2.
Class Bravo Fire Characteristics
- Produces black smoke.
- Ignited by fuel liquids.
- Examples of fuels: JP5, DFM, hydraulic fluid, and lube oil.
- Extinguishing agents include AFFF, PKP, and Halon.
Class Charlie Fire Characteristics
- Produces white/blue smoke.
- Caused by electrical equipment.
- CO2 is preferred; PKP is a last resort due to its corrosive properties.
Class Delta Fire Characteristics
- Involves aircraft and burning combustible metals.
- Key metals: magnesium and titanium.
- Generates heat exceeding 1400 degrees Fahrenheit, necessary to melt combustible metals.
- Extinguishing methods include jettisoning and using AFFF for cooling.
Principles of Fire Investigation
- Conduct investigations thoroughly, cautiously, and ensure accurate reporting, then repeat to validate findings.
