The condition in the compartment area changes rapidly as the fire change from one that is dominated by burning the materials first ignited that involves more available combustible material

flash-over

The fire totaly involve all available materials

fully developed

As the fire consumes all materials in the area, the rate of the heat released begins to decline

decay

3 stages of fire

incipient,free-burning phase,smoldering

Initial stage of fire (1000F)

incipient

(1330F) The material/structure are burning in the presence of adequate oxygen

free-burning phase

As the fire ceases, the dense smoke and heat completely feel the confine room

smoldering

Transfer of heat within solid or contacting solid

conduction

transfer of heat through movement of liquid and gas

convection

Transfer of heat through electro nagnetic wave

radiation

Method and material Cooling -

water

Method and material Seperation -

fuel

Method and material Smothering -

oxygen

Also known as the new arson law. Established penalties for arson and destructive arson in the philippines

pd 1613

Modes of transfer of heat

conduction,convection,radiation

Class A fire

ordinary combustible material - water

Class b fire

flammable liquid - foam/carbon dioxide

Class c fire

electrical equipment material - carbon dioxide/powder

Class d fire

flammable metal - special powder agent

Class e fire

Strategies in firefighting

locate the fire,confine the fire,extinguish the fire

To remove the smoke and heat

ventilation

Risk of spreading of fire to another structure or building

exposure

Factos to consider in firefighting

time,weather,fire,occupancy,ventilation

crucial in firefighting

time

Number of person that can occupied space at any given time

occupancy

Used to remove excessive heat and dense smoke

ventilation

Types of ventilation

vertical ventilation,cross or horizontal ventilation,mechanical force ventilation

It is used when the heat and dense smoke cant reach the higher level

cross or horizontal ventilation

Work from top to bottom

vertical ventilation

Method whereby a device is utilized such as smoke ejector to remove excessive heat and dense smoke

mechanical force ventilation

Basic tactics in firefighting

rescue,salvage,overhaul

Action of the firefighter to remove occupants from the burni by structure or building

rescue

Action taken by the firefighter to prevent excessive damage by the fire,water by removing of the materials from the area or by using salvage cover

salvage

A complete and detailed check of the structure or building to ensure that the spark and ember are totaly extinguish to avoid reignition

overhaul

Purpose of ladder for fire fighting

to stretch line to a building,to provide ventilation by giving access to a place that is hard to reach
