Fire Safety & Extinguisher Safety TrainingPhillipLaraway
There are three things needed to start a fire: oxygen, fuel, and heat. Fires are classified based on the type of fuel: Class A is solids like wood; Class B is liquids like gasoline; Class C is electrical fires; Class D are metal-based fires. There are three main types of fire extinguishers - water, carbon dioxide, and dry chemical. Water extinguishers use water to remove heat; carbon dioxide removes oxygen; and dry chemical extinguishers coat the fuel to block oxygen. It's important to remember the PASS method when using an extinguisher - pull the pin, aim at the base of the fire, squeeze the handle, and sweep from side to side.
This document provides an overview of basic firefighting. It discusses the chemistry and classification of fires into A, B, C, and D classes based on the type of fuel. Methods of fire extinguishing are described, including various types of fire extinguishers that use cooling, blanketing, or chemical reactions. Preventive measures are outlined such as prohibiting smoking and overloading electrical points. The document also explains fire safety systems like hydrants, smoke detectors, sprinklers, and manual call points.
There are different types of fire extinguishers designed for specific fire classes. Class A extinguishers use water or water with additives to fight fires fueled by ordinary combustibles like wood. Class B extinguishers contain chemicals to smother liquid fuel fires using pressurized water, foam or dry powder. Class C extinguishers are for electrical fires and use non-conductive agents like carbon dioxide or dry chemicals. Additional classes include Class D for combustible metal fires and Class K for cooking grease blazes. Each type works through mechanisms like cooling, oxygen removal or chemical suppression of the fire's chemical reaction.
This document provides an overview of fire, including its definition, causes, outcomes, classes, stages, combustion theory, and firefighting mechanisms. It defines fire as a rapid oxidation chemical reaction and notes that fires usually start small due to sparks from neglecting prevention. The main outcomes of fire are combustion gases, heat, flames, and smoke. Fires can be caused by human carelessness, natural causes, or technical failures. Combustion requires fuel, oxygen, heat, and a chain reaction. Firefighting works by removing one of these factors through starvation, smothering, cooling, or stopping the chain reaction.
The document discusses the fire triangle and the requirements for combustion: fuel, oxygen, and an ignition source. It also discusses flame structure and properties. Combustion requires the right concentrations of fuel and oxygen, sufficient temperature to ignite fuel, turbulence or mixing of fuel and oxygen, and enough time for complete combustion. A flame is a self-sustaining combustion zone that propagates at subsonic speeds through a confined mixture of fuel and oxygen. Flames have different zones with varying temperatures and degrees of combustion.

The document provides guidance on what to do in a fire emergency and types of portable fire extinguishers for different classes of fires. It emphasizes the importance of selecting the proper extinguisher and reviews the "PASS" method for operating a fire extinguisher.
This document provides information on fire extinguishers, including:
- There are different types of fires (A, B, C, D, K) that require different extinguishing agents.
- The main parts of a fire extinguisher are the label, handle/lever, locking pin, pressure gauge, and discharge nozzle.
- Fire extinguishers work by applying an agent that removes one of the elements (fuel, oxygen, or heat) needed for fire. When the handle is squeezed, gas forces the agent through the nozzle.
- It's important to select the proper extinguisher type for the fire and remember the PASS technique when using an extinguisher in an emergency

1) The document is a summary of Raoult's Law written by Muhammad Hamad Qureshi for the subject of Chemical Engineering Thermodynamics II.
2) Raoult's Law states that the vapor pressure of a solution is equal to the product of the vapor pressure of the pure solvent and the mole fraction of the solvent. The relative lowering of vapor pressure is directly proportional to the mole fraction of the solute.
3) When both components in a solution are volatile, Raoult's Law can be expressed as an equation of a straight line. The vapor pressures of ideal solutions will fall on this straight line.
This document discusses diffusion in solids. It defines diffusion as the tendency of molecules, atoms, or ions to distribute evenly in space due to random kinetic motion. Diffusion occurs due to concentration gradients and stops when concentrations equalize. In solids, diffusion results from thermally-activated random atomic motion. There are two mechanisms - interstitial, where small atoms fit between others, and vacancy, where atoms jump into vacant sites. Examples given are carbon diffusion in steel via the interstitial mechanism, salt dissolving in water as a solid-liquid diffusion example, and dust particles suspended in air as a solid-gas diffusion example.
LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UPRAHUL
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

Types of fire
1. Name : Muhammad Hamad Qureshi
Roll Number: D-19-CH-61
Topic : Fire and fire extinguisher
Department : Chemical engineering
Institute : Dawood UET, Karachi.
2. Types of fire:
Fires can be classified in six different ways depending on the agent that fuels them.
Types of fire Type of fire extinguisher used to cut off each fire
Class A: They involve solid materials
like wood, paper, plastic, or clothing.
Extinguish with water.
Foam fire extinguisher.
Dry powderExtinguisher.
Wet chemical Extinguisher.
Class B: Fires involving flammable
liquids like oil, paint, petrol.
gasoline, alcohol etc.
Dry powderExtinguisher.
Foam fire extinguisher.
Carbon dioxide extinguishers.
The last two type of extinguishers work by cutting off a fire's
oxygen supply.
Class C: Fires involving flammable
gases like butane, propane.
Dry powder.
Class D: fires involving burning
metals like aluminum, magnesium,
titanium etc.
Class D fires are oftentimes
caused by alkali metals such as
potassium, magnesium,
aluminum, and sodium, as these
can ignite when exposed to air or
water.
It requires high level of heat to
ignite metal, so this type of fire is
rare
Dry powder extinguishers
Dry powder extinguishers work on metal fires by separating
the fuel from oxygen or removing the heat element of the blaze.
Class E: Fires involving electrical
equipment’s.
It might be started by old wiring
in walls, frayed electrical cords,
worn-out breaker boxes, or
faulty appliances.
Carbon dioxide extinguishers.
Dry powder extinguishers.
CO2 extinguishers are ideal for places with a lot of electrical
equipment.
Dry powder can also be used on fires involving electrical
equipment however, they do not cool the fire so it can re-ignite.
It can also create a loss of visibility and may create breathing
problems. They are not generally recommended for use inside
buildings unless there is absolutely no alternative.
3. Class F: Fires involving cooking oil
and fats.
Becauseof the high flashpoint of
cooking oils and fats, Class F fires
often start when a pan is left
unattended for too long on a
stove.
Wet Chemical Extinguisher.
Water Extinguishers:
Water extinguishers are mostly used
for class A fire risk. They involve solid
materials like wood, paper, plastic, or
clothing. As far as the inner workingis
concerned, a water extinguisher works
by having a cooling effecton the liquid
that causes the burning fuel to burn at
a slower rate until the flames are
completely extinguished.
All water extinguishers have a red
label.
Don’t usedfor:
o Fire involving flammable liquids
o Fire involving Electrical equipment’s
o Kitchenfires
4. Foam fire extinguisher:
Foam extinguishers are some of the
best for liquid fires, such as gasoline
fires, but can also be used on Class A
fires involving solid combustibles like
wood.
Theyspray a type of foam that expands
whenithitsthe air and blanketsthe fire.
Thisblanketpreventsthe vaporsfrom
risingoff the liquidtofeedthe fire,thus
starvingitof fuel.Also,becausethe foamis
mixedwithwater,ithasa coolingeffectas
well.
All fire foam extinguisher have a cream
label.
Don’t usedfor:
o Fire involving Electrical equipment’s
o Kitchenfires
o Fires involving metals
Dry Powder Extinguishers:
Powder extinguishers are a good multi-
purpose fire extinguisher because they can
be used on Class A, B and C fires. They can
also be used on fires involving electrical
equipment however, they do not cool the fire
so it can re-ignite. They are not generally
recommended for use inside buildings unless
there is absolutely no alternative.
Powder extinguishers have a blue label.
Don’t usedfor:
o Make sure it is not uesd inside
the buildings(closedair) because
it can cause loss of visibility and may create breathing problems.
o It is also not used for electrical equipment over 1000 V.
5. Carbon Dioxide (CO2)
Extinguishers:
CO2 extinguishers are ideal for places
with a lot of electrical equipment’s.
They also put out Class B fires. CO2
extinguishers suffocate fires by
displacing the oxygen the fire needs to
burn. CO2 extinguishers work by
smothering the fire and cutting off the
supply of air.
This type of extinguisher has a black
label.
Don’t used for:
o Kitchenfires
o Fires involving metals
o Solidmaterial involving wood, paper etc.
Wet Chemical Extinguishers:
Wet chemical extinguishers are suitable
for use on Class F fires involving cooking
oils and fats, such as lard, olive oil,
sunflower oil, maize oil and butter. They
are extremely effective, when used
correctly. The wet chemical rapidly
knocks the flames out, cools the burning
oil and chemically reacts to form a soap-
like solution, sealing the surface and
preventing re-ignition.
Wet chemical extinguishers have a
yellow label.
Don’t usedfor:
o Flammable liquids and gas fires
o Fire involving Electrical equipment’s
