Discussion:
(Discuss or explain the following base on your own understanding or perception of the subject/
phrase/words/statement)

1. Explain the difference between Vapor Density and Vapor pressure.

Vapor Density is the density of a particular vapor or gas as it relates to air. It may be
defined as mass of a certain volume of a substance divided by mass of same volume of
hydrogen. Vapor density = mass of n molecules of gas / mass of n molecules of
hydrogen.
While Vapor Pressure is the pressure exhibited by vapor present above a liquid
surface. As the temperature of a liquid increases, the kinetic energy of its molecules
also increases. The vapor pressure that a single component in a mixture contributes to
the total pressure in the system is called partial pressure.

2. Discuss what is Exothermic Reaction as a Chemical Property of Fire, and give situation
or example that exothermic reaction takes place.

An Exothermic Reaction is the chemical reaction in which heat is given out. It give off
heat to the surrounding causes it to a rise in temperature.
Example of exothermic reaction is a bonfire wherein it releases a heat and light energy
in its surrounding. You can see the light energy the fire is giving off and if you were
standing near the fire, you would also feel its heat.

3. What is a Flame? Give and explain the different type of flames.

A flame is the visible, gaseous part of a fire. It is caused by a highly exothermic

chemical reaction taking place in a thin zone. If hot enough, the gases may become
ionized to produce plasma.
There are three types of flames natural flame, carburizing flame and oxidizing flame.
 Natural Flame is a type of flame that produces little smoke. This flame has two
zones. The inner zone has white in color and has temperature about 3100
degree centigrade and outer zone has blue color and have temperature about
1275 degree centigrade.
 Carburizing Flame is smoky and quiet flame. This flame has excess of fuel gas.
This flame chemically reacts with metal and form metal carbide. This flame has
three regions. The inner zone has white color, the intermediate zone which is
 red in color and outer cone has blue color. The inner cone temperature is
about 2900 degree centigrade.
 Oxidizing Flame is hotter than natural flame. It is a flame obtain when the
amount of acetylene reduces from natural flame or amount of oxygen
increases. This flame has two zones. The inner zone has very bright white color
and has temperature of about 3300 degree centigrade. The outer flame has
blue in color.

4. Discuss what is combustion.

Combustion also known as burning is a chemical reaction that occurs between a fuel
and an oxidizing agent that produces energy, usually in the form of heat and light. It is
considered an exergonic or exothermic chemical reaction.

5. Illustrate and Explain the FIRE TRIANGLE.

The fire triangle is a simple model to understand the necessary ingredients of fires. It
illustrate the three components needed to ignite and sustain a fire. Removing one of
the component of fire triangle will cause the fire to cease. The three ingredients of a
fire triangle are; heat (such as the Sun, hot surfaces, sparks, friction and electrical
energy), fuel (it can be in a form of solid, liquid or gas) and oxidizing agent (usually
oxygen).

UNIT 2 : COMBUSTIBLE MATERIALS

GENERAL INSTRUCTIONS: Define or explain, identify or enumerate the following questions!

I. DISCUSSION

1. Define combustible materials and explain its connection to fire

Combustible material means a material that, in the form in which it is used and under
the conditions anticipated, will ignite, burn, support combustion or release flammable
vapors when subjected to fire or heat. Wood, paper, rubber, and plastics are examples
of combustible materials. A combustible material is flammable if it ignites easily at
ambient temperatures. In other words, a combustible material ignites with some
effort and a flammable material catches fire immediately on exposure to flame.

2. Explain why the fibers and textiles are considered as combustible materials.

Because they will burn whenever there is a source of ignition that is producing enough
energy (for that particular fabric/fiber) to combust the organic compounds present.
When textiles and fibers are heated by an ignition source, the polymer molecules start
to break up (a process called pyrolysis) into smaller molecules. Some of these pyrolysis
products are “fuels” capable of burning.
 3. Give the difference between liquid and gas in relation to fire.

Liquid in relation to fire refers to the Flammable and combustible liquids. Flammable
liquids will ignite (catch on fire) and burn easily at normal working temperatures.
Combustible liquids have the ability to burn at temperatures that are usually above
working temperatures. Liquids themselves do not burn. It is the mixture of their
vapors and air that burns. Vapors from the evaporation of these liquids when exposed
to air under the influence of heat, which will burn or explode. While Gas is a matter
than can react in combustion. Gases are made up of molecules (groups of atoms).
When these gases are hot enough, the molecules in the gases break apart and
fragments of molecules rejoin with oxygen from the air to make new product
molecules – water molecules (H2O) and carbon dioxide molecules (CO2) – and other
products if burning is not complete. The gas molecules combine with oxygen in the air
resulting in burning. The heat generated by the reaction is what sustains the fire. The
heat of the flame will keep remaining fuel at ignition temperature. The flame ignites
gases being emitted, and the fire spreads.

 Discussion
 What is Combustible Chemical and what are the common example of it?

Combustible Chemical is a chemical in the form in which it is used and under

the conditions anticipated, will ignite, burn, support combustion or release
flammable vapors when subjected to fire or heat. Combustible chemical has
the potential to explode or ignite when mixed with oxygen. Common examples
of combustible chemical are Carbon black, Lampblack, Lead thiocyanate,
Peroxides, Sulfides, Sulfur, and Naphthalene.

 How can we extinguish fire cause by oxidizing chemicals?

 Water appears to be the only suitable extinguishing agent for fires involving
inorganic oxidizing agents. It may be possible to extinguish a fire involving
peroxide spill with a dry chemical extinguisher or by smothering with dry sand
or soda ash. If these methods fail the area should be flooded with water from
hose stream.

 Define what is corrosive chemical and discuss how can it cause fire.

Corrosive chemical are highly irritant that can attack and chemically destroy
exposed body tissues. Corrosive chemical can also damage or even destroy
metal. They begin to cause damage as soon as they touch the skin, eyes,
respiratory tract, digestive tract, or the metal.
Some corrosives are also flammable or combustible and can easily catch fire
and burn or explode. Some corrosives are incompatible with other chemicals.
They may undergo dangerous chemical reactions and give off toxic or explosive
products if they contact each other.

 What is a smoke and discuss its effects as combustion product?

Smoke consists of condensed vapor and small bits of solid particle that are sent
into the air when something burns. Smoke provides warning of fire and
contributes to panic because of its irritating effects. The small particles of
carbon and tarry particles as well as oxides of nitrogen condensed steam and
other atomized liquids are the ones responsible for the visible phenomenon of
fire gases which is the smoke. The solid and liquid particles in suspension in the
gases have harmful effects. Some particles are irritating when inhaled and long
exposure to smoke particles may cause damage to the respiratory system.
When the particles are lodged in the eyes, they cause tears which may impair
victim’s vision; when settled in nostril and throat, they may cause sneezing and
coughing.

 As a product of combustion, explain how heat cause the spread of fire and what
are the effects of heat in human during a fire.

Heat causes the fire to spread because it is one of the component of fire
together with oxygen and fuel. Convection is the most dangerous way in which
fire can spread through a property. The heat generated by a fire naturally rises,
but in an enclosed space such as an office, this heat becomes trapped when it
hits the ceiling. The heat then travels horizontally, spreading the fire across the
entire space. Exposing to heat during fire can cause dehydration, heat
exhaustion, blockage of respiratory tract due to fluids and burns and also
 increased heart rate. When the intensity of heat goes beyond the threshold of
human tolerance, it is fatal.
