The Fire Tetrahedron - Four Essential Elements
Notes
Fundamental concept that underlies all firefighting strategies
Examples
- Smothering removes oxygen (CO₂ extinguisher)
- Cooling removes heat (water)
- Removing fuel (turning off gas valve)
- Breaking chain reaction (dry chemical)
Fire requires all four elements to exist. Remove ANY ONE element and the fire dies. This principle drives every firefighting tactic and forms the foundation of fire science.
Main points
- Fuel: Combustible materials (wood, paper, gasoline)
- Heat: Temperature sufficient to ignite
- Oxygen: Usually from air (21% O₂)
- Chemical Chain Reaction: Sustained molecular reaction

Stages of Fire Development
Notes
Critical for understanding fire behavior and tactical decisions
Examples
- Cigarette igniting paper (incipient)
- Room fire spreading to furniture (growth)
- Entire room involved (fully developed)
- Smoldering remains (decay)
Understanding fire stages helps predict behavior and choose appropriate tactics. Early detection during incipient stage saves lives and property. Decay stage presents unique backdraft hazards.
Main points
- Incipient: Initial ignition, easily extinguished
- Growth: Heat builds, flames spread rapidly
- Fully Developed: Maximum heat, highest danger
- Decay: Fuel exhausted, backdraft risk

Heat Transfer Modes - How Fire Spreads
Notes
Essential for predicting fire behavior and tactical positioning
Examples
- Steel beam conducting heat to next room
- Hot smoke rising up stairwell
- Radiant heat breaking windows across street
- Combination of all three in large fires
Fire spreads through three distinct mechanisms. Knowing which mode dominates helps firefighters predict spread patterns and position resources effectively.
Main points
- Conduction: Heat through solids (metal beams)
- Convection: Hot gases rise (stairwells, shafts)
- Radiation: Heat waves (window to window)
- Understanding mode predicts fire spread

Fire Classification System
Notes
Critical for selecting proper suppression method and extinguisher type
Examples
- House fire involving furniture (Class A)
- Gasoline spill fire (Class B)
- Electrical panel fire (Class C)
- Kitchen grease fire (Class K)
Fire classification determines which extinguisher and suppression method to use. Using wrong extinguisher can spread fire or create safety hazards. NEVER use water on Class B, C, or D fires.
Main points
- Class A: Ordinary combustibles (wood, paper, cloth)
- Class B: Flammable liquids/gases (gasoline, propane)
- Class C: Energized electrical equipment
- Class D: Combustible metals (magnesium, sodium)
- Class K: Cooking oils and fats

Fire Extinguisher Types and Applications
Notes
Essential reference for selecting correct extinguisher in emergency
Examples
- Water cools burning wood (removes heat)
- CO₂ displaces oxygen around electrical fire
- Foam blankets gasoline spill
- Wet chemical saponifies cooking oil
Each extinguisher type works by removing one element of the fire tetrahedron. Matching the right extinguisher to the fire class is essential for effective suppression and safety.
Main points
- Water: Class A only (ordinary combustibles)
- Foam: Class A and B (liquids and solids)
- CO₂: Class B and C (liquids and electrical)
- Dry Chemical ABC: Class A, B, and C
- Wet Chemical: Class K (kitchen fires)
- Special Powder: Class D (metals) only

PASS Technique for Extinguisher Use
Notes
Universal technique that all citizens should know
Examples
- Kitchen grease fire: aim at base of pan
- Wastebasket fire: aim at burning material
- Gasoline spill: sweep across fuel surface
- Always maintain escape route behind you
The PASS technique ensures effective extinguisher use. Aiming at flames is ineffective - always aim at the base where fuel is burning. Keep yourself between fire and exit route.
Main points
- P - Pull the pin to break seal
- A - Aim at the base of the fire
- S - Squeeze the handle to discharge
- S - Sweep side to side at fire base
