A chemical reaction that takes place in the form if light and noticable heat

Elements of fire

Source of ignition

Combustible material(reducing agent), anything that can be burned with sufficient evidence

Oxydizing agent, supports fire

Percentage of oxygen

Percentage of nitrogen

Percentage of impurities

4 types of energy

3 types of fuel

Molecules packed together

Molecules loosely packed

Molecules are free to move

It is a malicious intent of burning

Elements of arson

Common source of heat during combustion process

Two types of mechanical energy

Movement if two surfaces against each other thus, producing spark

Heat is produced when the gas on air is compressed inside the cylinder or container

To produce energy

Fire development Stages

When the four tetrahedron combines, the combustion begins

Fire plume begins to occur, begins to entrain air from the surroundings

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

The fire totaly involve all available materials

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

3 stages of fire

Initial stage of fire (1000F)

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

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

Transfer of heat within solid or contacting solid

transfer of heat through movement of liquid and gas

Transfer of heat through electro nagnetic wave

Method and material Cooling -

Method and material Seperation -

Method and material Smothering -

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

An act establishing a comprehensive fire code of the philippines repealing presidential decree no 1185 and for other purposes

Modes of transfer of heat

Class A fire

Class b fire

Class c fire

Class d fire

Class e fire

Fire tethrahedron

Removing the oxygen

Capital punishment on atsonist

Strategies in firefighting

To remove the smoke and heat

Risk of spreading of fire to another structure or building

Factos to consider in firefighting

crucial in firefighting

Number of person that can occupied space at any given time

Used to remove excessive heat and dense smoke

Types of ventilation

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

Work from top to bottom

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

Basic tactics in firefighting

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

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

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

Purpose of ladder for fire fighting
