  1. HOW DOES FIRE GROW?

  2. The fire triangle 3 combined elements create a continuous chemical reaction resulting in combustion Take away just one and the chemical reaction is interrupted and the fire goes out

  3. Camp fires FIRE DOUBLES IN SIZE EVERY 30 SECONDS Everyone has seen one of these They Have a Simple growth chart

  4. Compartment fires Ventilation limited Can be controlled High pressure High heat

  5. Room and contents Watch for: Insipient stage Growth stage Rollover Flashover Decay phase

  6. smoke • Smoke inhalation is the primary cause of death in victims of indoor fires • Extremely toxic Superheated gases • Carbon monoxide • Hydrogen cyanide • AND MORE... • Composition depends on the nature of the fuel • Less oxygen = more smoke • Unburnt byproducts May ignite resulting in backdraft or smoke explosion Collection of airborne solid and liquid particulates and gasses emitted when a material undergoes combustion

  7. Thermal layering Fire department disrupts this layering with water stream which changes to steam and dissipates heat

  8. WHY ARE DOORS SO Important? Protection from heat Limit the flow of oxygen Limits the spread of toxic smoke Increases time to escape or for rescue to arrive
