Chapter 4: Chemistry and Physics of Fire
Definition of fire: Fire is a rapid and self-sustaining oxidation process that is assisted by the generation of heat and light in various degrees of intensity. As stated in your textbook, fire is the process of oxidation and is associated with the term combustion, which is the chemical chain reaction that releases both light and heat. For all intents and purposes, fire is both friend and foe. We use fire for heating, cooking, manufacturing, and controlling other fire sources.
Fire triangle and fire tetrahedron: Perhaps as a child you were taught that fire was represented by a triangle with each side denoting one of the three components required to sustain fire: air, fuel, and heat. Classically known as the Fire Triangle we learned that by removing any one of the three components fire would be extinguished.

Over time, the scientific community has added another dimension called the chemical reaction found during the combustion process. With the addition of this fourth side we now have the new symbol of fire called the fire tetrahedron.
Chemistry of fire: Fire needs two basic elements in order to sustain its existence, and without the two in union, fire cannot occur. These two elements are oxidizer and fuel.
Oxidizer: An oxidizer is any substance that generates oxygen. The most common and abundant oxidizer ...

This chapter discusses collecting and reporting occupational safety and health data for emergency services. It covers collecting internal organization data, external data required by outside organizations, and publishing internal reports. The chapter also addresses using the internet as a source of safety and health information. Key topics include the purpose of data collection and reporting, identifying what data to collect internally and externally, and how to publish reports and access online information resources.
This chapter discusses information management for occupational safety and health in emergency services. It covers collecting data internally on injuries, accidents, medical histories and test results to analyze safety trends and evaluate programs. Data is also reported externally to agencies like OSHA, NFPA and state workers' compensation boards. The chapter outlines publishing an annual internal safety report to communicate accomplishments, goals and injury analyses. It also discusses using the internet to research safety policies from other departments.
This chapter discusses evaluating occupational safety and health programs for emergency services. It covers the purpose of evaluating programs to ensure processes and outcomes are effective. Evaluations should assess both how the program is implemented and its impacts. The chapter recommends those responsible for the program, such as safety managers, conduct regular evaluations, at least yearly, to constantly improve worker protection.
This chapter discusses evaluating occupational safety and health programs for emergency services. It describes conducting both process evaluations to analyze program procedures and outcome evaluations to compare results to goals. Process evaluations ask how program parts affect members and which parts are most/least effective. Outcome evaluations analyze injury rates, knowledge/behavior changes, and policy response over time. The fire chief or safety manager usually oversees evaluations through committees and staff. NFPA 1500 recommends external evaluations every three years to demonstrate improvement efforts. Evaluations should occur before programs begin and be continuous for process and yearly for outcomes, or when serious incidents or changes require reevaluation.

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.

4. Behavior of Fire (1 of 2)
‣ Question to ask students:
‣ What are the dangers associated with backdrafts,
how do they form, and how can they be prevented?
5. Behavior of Fire (2 of 2)
‣ Fuel, oxygen, and heat are required to produce fire and
are represented as the fire triangle.
‣ A fire will cease to exist if any one of the three sides is
removed.
‣ Removal of fuel is typically not an option.
‣ Covering or smothering may remove oxygen.
‣ Cooling agents are used to reduce heat.
6. Fire Tetrahedron (1 of 2)
‣ A fourth method for extinguishing a fire is to interrupt the
chemical reaction of fuel, oxygen, and heat with an
extinguishing agent.
‣ This is referred to as the fourth side of the triangle.
‣ The fire triangle becomes a fire tetrahedron.
‣ Define the three sides of the fire triangle and their role in
fire behavior. Also describe the “fourth side of the
triangle” and its mechanism of action.
7. Fire Tetrahedron (2 of 2)
‣ Question to ask students:
‣ Define the three sides of the fire triangle and their
role in fire behavior. Also describe the “fourth side of
the triangle” and its mechanism of action.
8. Classes of Fires
‣ In the United States, fires are categorized into five
classes: A, B, C, D, and K.
‣ This system is used to identify the type of fire
extinguisher needed.
9. Class A Fires
‣ Involve ordinary combustible materials: wood, paper,
textile, etc.
‣ Commonly extinguished with water, water plus an
additive, or fire extinguishers.
‣ Typical additives are Class A foam and high expansion
foam.
‣ Class A extinguishers are marked with a green triangle
containing the letter A.
10. Class B Fires
‣ Involve flammable liquids, combustible liquids, petroleum
greases, tars, oils, solvents, lacquers, alcohols, and
flammable gasses.
‣ Extinguished using foam and fire extinguishers.
‣ Class B extinguishers are marked with a red square
containing the letter B.
11. Class C Fires
‣ Involve energized electrical equipment.
‣ Dry chemical and carbon dioxide fire extinguishers are
utilized.
‣ Class C extinguishers are marked with a blue circle
containing the letter C.
12. Class D Fires
‣ Involve combustible metals.
‣ Water should not be used because it can result in
explosion.
‣ Purple K and other specialized fire extinguishers should
be used.
‣ Class D extinguishers are marked with a yellow star
containing the letter D.
13. Class K Fires
‣ Involves cooking appliances with vegetable oils, animal
oils, or fats.
‣ Fought with special fire extinguishers that are generally
found in commercial kitchens.
‣ Class K extinguishers can be used simultaneously with
hood suppression systems found in commercial kitchens.
‣ Class K fires should not be confused with Purple K fire
extinguishers, which are designed for Class C fires.
‣ Class K extinguishers are marked with a black hexagon
containing the letter K.
14. Spread of Heat
‣ Heat is generated when a combustible material comes in
contact with a heat source-if oxygen is present, the
material will burn.
‣ Heat can spread to other materials and areas.
15. Methods of Heat Transfer
‣ Heat can be transferred through direct contact with
flames, as well as:
‣ Conduction
‣ Convection
‣ Radiation
16. Conduction
‣ Heat is transferred through direct contact of materials.
‣ Material with greater temperature will transfer heat to
material with lower temperature.
‣ Ease of fire spread depends on the combustibility of the
materials involved.
17. Convection
‣ Heat is transferred by a gas or liquid.
‣ Movement of heated air currents can spread fire to
uninvolved areas.
‣ Staircases are a ready path for air currents to spread fire
to upper floors.
‣ Proper use of ventilation can prevent fire spread by
convection.
18. Radiation
‣ Heat rays from a fire travel in straight lines in all
directions from a fire.
‣ Rays continue until heat is dissipated or they meet an
object that may absorb the heat and ignite.
‣ Exposed buildings can be protected by cooling with water
streams.
19. Stages of Fire
‣ The five stages of fire are:
‣ Ignition
‣ Growth
‣ Flashover
‣ Fully developed
‣ Decay
20. Ignition Stage
‣ Initial stage where fuel, oxygen, heat, and the uninhibited
chemical chain reaction come together.
21. Growth Stage
‣ Stage where fire develops.
‣ Dependent on the amount of fuel and oxygen available.
‣ Contents of the room become heated as the temperature
of the fire increases.
‣ Greater fire department response is required.
22. Flashover Stage
‣ The transition between the growth stage and a fully
developed fire.
‣ Characterized by the simultaneous ignition of the surface
area of combustible materials in the fire space.
‣ Temperatures estimated at 900 to 1100 degrees F.
23. Fully Developed Stage
‣ Occurs when all combustible materials are involved in the
fire.
‣ Heat will be at a maximum.
‣ Temperatures can exceed 2000 degrees F.
24. Decay Stage
‣ Occurs when the oxygen or fuel sources diminish.
‣ Large volumes of smoke containing carbon monoxide are
produced.
‣ A lack of oxygen can create a smoldering state that might
lead to a backdraft or “smoke explosion.”
25. Multiple Growth and Decay Stages
(1 of 4)
‣ An outside fire may have sufficient oxygen to burn freely.
‣ The burning of a fire in an enclosed structure is
dependant on fuel and oxygen.
‣ A fire in a structure during growth stage is called fuel-
limited/controlled.
‣ A ventilation-limited/controlled fire occurs as the burning
increases.
26. Multiple Growth and Decay Stages
(2 of 4)
‣ The oxygen level reduces below 21 percent.
‣ The initial decay stage occurs once the oxygen level gets
below 16 percent.
‣ A pulsing action of smoke may appear as the decaying
fire draws in more oxygen.
‣ If more air is unable to be pulled in, the fire will self-
extinguish.
27. Multiple Growth and Decay Stages
(3 of 4)
‣ A second growth stage can occur and transition the fire
to flashover.
‣ After flashover, the fire is burning more than can be
supported by the entrained air.
‣ If the fire is not vented, but is venting, it will enter the fully
developed stage.
‣ If additional ventilation openings are created, the third
growth stage can occur.
28. Multiple Growth and Decay Stages
(4 of 4)
‣ The fire will remain ventilation-limited unless:
‣ Additional oxygen is made available.
‣ The fire becomes fuel-limited.
‣ Suppression is initiated and water is applied to the
fire.
29. Rollover
‣ The fire or flame front often observed rolling in front of
burning materials.
‣ A fuel-rich air can get pushed ahead of a fire.
‣ When it comes into its flammable limits, it burns.
‣ Fire appears to be rolling along at ceiling level 10 to 20
feet ahead of the main fire.
30. Flashover
‣ The ignition of combustibles in an area heated by
convection, radiation, or both.
‣ Combustibles are heated to their ignition point and ignite
almost simultaneously.
‣ Warning signs include intense heat, fog streams turning
to steam, and smoking of unburned articles.
‣ To reduce likelihood, lower temperatures using ventilation
and water.
31. Backdraft
‣ A rare explosion created as a developing fire creates air
deficient in oxygen.
‣ Explosive gases build up and high temperatures turn fuel
into ignitable vapors.
‣ Sudden oxygen entry causes the gases to ignite, readily
causing a violent explosion.
‣ Ventilation is the first priority in prevention.
32. Training (1 of 2)
‣ Question to ask students:
‣ Who benefits from training?
33. Training (2 of 2)
‣ Backbone of fire department
‣ Helps increase speed of an operation
‣ Enhances proper execution while reducing injuries
‣ Benefits everyone (firefighter, company officer, fire
department, and the community)
‣ A firefighter who arrives at an emergency unprepared can
be faced with life-and-death situations and will find
themselves under extreme stress to perform the
necessary duties.
34. Firefighter Benefit
‣ Training helps new members learn basic skills.
‣ Training helps senior members keep their skills sharp.
‣ Training helps reduce errors.
‣ Training helps firefighters gain confidence in themselves
and assume further responsibilities.
35. Company Officer Benefit
‣ Better control over operations
‣ Frees up officer to assume greater responsibility
‣ Creates a more pleasant relationship between officer and
firefighters because well-trained firefighters enable the
officer to have less fear of emergencies
36. Department Benefit
‣ Efficiency of fire department is recognized by the citizens
it protects.
‣ Training improves community relations.
‣ Training keeps morale at a high level, contributing to
pleasant working conditions.
37. Preparation Is Required (1 of 3)
‣ Exercises must be challenging.
‣ Reading from a text is boring!
‣ An officer needs to prepare well to ensure the goals of
the training exercise will be attained.
‣ An officer can maintain interest in the subject by asking
questions and seeking input from all participants.
38. Preparation Is Required (2 of 3)
‣ Training permits mistakes to be made in a nonemergency
setting.
‣ Training exercises can be stopped to point out and
correct procedures.
39. Preparation Is Required (3 of 3)
‣ Questions to ask students:
‣ What are “performance standards” or “timed
evolutions”?
‣ Why would time frames be used in these evolutions?
‣ What performance standards or timed evolutions are
used in their individual departments?
40. Performance Standards (1 of 2)
‣ Establish performance standards or timed evolutions for
engine and truck/ladder companies; trainees utilizing that
criteria will be better prepared to handle the varied
problems that occur at an incident scene.
‣ Start with basic evolutions and then add more complex
additional functions.
‣ The entire evolution must be specific and documented.
41. Performance Standards (2 of 2)
‣ There should be a maximum amount of time to complete an
evolution.
‣ Speed alone should not be the determining factor; safe
operations and adhering to the entire performance standard
must be judged.
‣ Videotaping evolutions is an excellent training and feedback
tool.
‣ Company officers should take note of the time it takes to
complete an evolution. For example, noting how long it takes
to place a master stream will aid in assigning tactical
operations in a real emergency.
42. Cross-Training
‣ Fire departments should regularly schedule training
involving multiple units, including specialized units such
as heavy rescue and hazardous materials.
‣ Hands-on training provides an opportunity to better
understand how the various units function, allowing an
emergency scene to operate smoothly.
‣ Train routinely with mutual-aid departments.
‣ Enable members to develop friendships and share
experiences, benefiting each department when called
upon to work together in future incidents.
43. Preincident Planning (1 of 2)
‣ Questions to ask students:
‣ Why should fire departments conduct building
inspections and preplan buildings?
‣ What is the benefit to the fire department from
preplanning?
‣ What is the benefit to the property owner?
‣ What is the benefit to the firefighter?
44. Preincident Planning (2 of 2)
‣ Provides information.
‣ Is a method of gathering facts about a building or a
process within a building.
‣ Lets a fire department evaluate conditions and situations
prior to an emergency.
‣ Fire departments that utilize preplanning can mean the
difference between success or failure at an emergency
incident.
‣ Preincident planning allows fire departments to anticipate
potential problems and analyze possible solutions.
45. Preplanning Responsibility (1 of 3)
‣ Preplanning responsibility starts with the fire chief.
‣ A chief officer should be assigned to oversee the
preincident planning programs.
‣ This permits standardization and continuity of all
preplans.
46. Preplanning Responsibility (2 of 3)
‣ Target hazards for which preincident plans should be
prepared; include buildings or processes:
‣ That pose a high threat to life safety of those who
work in the building or facility and to those who live
nearby
‣ That would create safety problems for firefighters and
other emergency responders
‣ That could create a conflagration hazard
‣ That would present unusual and demanding
situations for responding firefighters
47. Preplanning Responsibility (3 of 3)
‣ That have a high frequency of fires
‣ That would have a large economic impact on the
community
‣ Consult historical data, as well as national and local
statistics.
‣ This analysis assists in determining potential problems.
48. Documentation (1 of 2)
‣ The preplanning process begins with an on-site survey.
‣ The responsibility for gathering information is usually assigned to
the first-due engine or truck company.
‣ Site survey data can be stored:
‣ On large index cards for easy reference
‣ In a booklet consisting of multiple pages
‣ In a database that can be printed out at the time of the alarm
‣ On a palm-sized or handheld computer
‣ Combination of an index card system that is backed by a
booklet
49. Documentation (2 of 2)
‣ Quality is the important concern. An overwhelming
amount of data can be counterproductive.
‣ The booklet method can contain a section on fire
department concerns. It can include information on
standpipes, building renovations, etc.
‣ Phone numbers and emergency contact personnel can
change.
‣ Responders should review and update the information
during site visits.
50. Considerations (1 of 2)
‣ Analysis of each situation merits questions:
‣ How will we be able to protect building occupants and
those in threatened exposures?
‣ What evacuation plans have been formulated?
‣ Are there other means by which occupants can be
protected, such as lateral evacuation or protecting in
place?
‣ Are there protective systems in the building?
51. Considerations (2 of 2)
‣ On-site survey should consider how construction features
and protective systems impede or assist the fire
department once a fire occurs.
‣ Another benefit derived from preplanning is that
command decisions can be made under nonemergency
conditions. This reduces the stress on the Incident
Commander during an emergency.
52. Resource Utilization
‣ Preplan should consider the availability of resources.
‣ Anticipate reduced staffing and develop alternate
strategies.
‣ Preplan should address utilization of outside agencies,
i.e., police and Red Cross, and the specific duties
expected of them.
53. Considerations
‣ Development and utilization of an incident management
system that all agencies use is instrumental in dealing
with large-scale incidents.
‣ Anticipating specific problems allows prior thought and
research on the part of the individuals who may assume
specific roles in the command system.
54. Disaster Planning
‣ There are certain facilities where, should an emergency
occur, there could be a direct impact on the surrounding
community.
‣ These include chemical plants, refineries, testing labs,
and large water purification plants.
‣ These sites will require large-scale plans with multi-
agency planning and community input.
‣ The preplan should take into account any special
equipment required and mutual-aid response.
55. Plan Review
‣ Review of the preplan with the personnel of the affected
facility is a positive step.
‣ Facility personnel can be utilized as technical specialists
that can assist the Incident Commander during an
emergency.
56. Testing the Plan (1 of 2)
‣ Implementation of the preplan during a simulated
exercise assists in adjusting the plan as needed.
Consider:
‣ What worked well?
‣ What needs to be adjusted?
‣ What problems did the fire department encounter?
‣ If the community was involved in the exercise, did
they have any problems?
‣ Did the plant or facility find any discrepancies in the
plan?
57. Testing the Plan (2 of 2)
‣ Encourage the addition of contingency plans for
foreseeable problems and their incorporation into the
exercises.
‣ Review the plan annually to see if any modifications are
needed.
58. Needed Fire Flow (1 of 4)
‣ Questions to ask students:
‣ How do we know how much water will be required to
control and extinguish a fire?
‣ Is anyone familiar with the needed fire flow formula
taught at the National Fire Academy?
59. Needed Fire Flow (2 of 4)
‣ The Incident Commander at a fire scene needs to know
how much water will be needed for effective fire control.
‣ This is best accomplished during the preplanning stage.
‣ When preplanned information is available to the initial
Incident Commander upon arrival at an incident, strategic
and tactical decisions can be made more readily and
accurately.
60. Needed Fire Flow (3 of 4)
‣ To determine needed fire flow during preplanning
requires the application of a fire flow formula to conditions
observed during an inspection of the premises.
‣ When fire flow information is not available, the National
Fire Academy (NFA) formula allows for quick
calculations.
‣ The NFA formula provides a starting point for deciding
the amount of water required at an incident scene.
61. Needed Fire Flow (4 of 4)
‣ NFA formula:
‣ Fire flow = length × width ÷ 3
‣ Example:
‣ Single family dwelling 60 ft × 20 ft and one-story high
‣ 60 × 20 ÷ 3 × 1 = 400 gallons per minute (gpm)
‣ 100% involvement = 400 gpm
‣ 50% involvement = 200 gpm
‣ 25% involvement = 100 gpm
‣ Quick-calculation formula indicates that, if the dwelling were fully
involved, 400 gpm would be required to effectively control the fire.
62. Figure 1-13 To calculate fire flow for a single-
family dwelling 60 feet long by 20 feet wide.
Used with permission of Michael DeLuca
63. Multistory Structures (1 of 2)
‣ In multistory buildings, if more than one floor in the
building is involved, fire flow is based on the area
represented by the number of floors actually burning.
‣ Example:
‣ Fire flow for a two-story building with similar
dimensions to the one in the previous example would
be:
‣ 60 × 20 ÷ 3 × 2 (floors) = 800 gpm if fully involved
64. Multistory Structures (2 of 2)
‣ If other floors in a building are not yet involved, but are
threatened by possible extension of the fire, they should
be considered as interior exposures, and 25 percent of
the required fire flow of the fire floor should be added for
exposure protection for each exposed floor above the fire
door to a maximum of five interior exposures.
65. Figure 1-14 A charge of 25 percent will be calculated
for each floor above the fire floor up to a maximum of
five floors. Used with permission of Michael DeLuca
66. Exterior Exposures (1 of 5)
‣ If exterior exposures are being exposed to fire from the
original fire building, 25 percent of the actual required fire
flow for the building on fire should be added to provide
protection for each side of a building that has exterior
exposures.
67. Exterior Exposures (2 of 5)
Figure 1-15
If exterior exposures are being threatened by fire from the original fire building, 25 percent
of the actual required flow for the building on fire should be added to provide protection for
each side of a building that has exposures. Used with permission of Michael DeLuca.
68. Exterior Exposures (3 of 5)
‣ Example:
‣ From our previous one-story dwelling with exposed
exterior structures on two sides of the fire building:
‣ 60 × 20 ÷ 3 × 1 = 400 gpm
‣ 2 exposures: 400 gpm × (25% × 2) = 200 gpm
‣ Total fire flow required = 600 gpm
69. Exterior Exposures (4 of 5)
‣ If the exposure becomes involved in the fire, the
exposure(s) should then be treated as a separate fire
area and calculated separately, then added to the
required fire flow for the original fire area.
‣ Remember-the quick calculation is an estimation of the
water needed to control the fire.
‣ The formula is geared toward an offensive attack, and its
accuracy diminishes with fire involving more than 50
percent of a structure and with defensive operations.
70. Exterior Exposures (5 of 5)
‣ Firefighting is not an exact science.
‣ The quick-calculation formula cannot be expected to
determine the exact gpm that will be specifically required
for full fire control.
71. Available Water Supply
‣ Available water flow must be known.
‣ Type and location of water supplies should be specified.
‣ Provide exact locations if using hydrants or drafting sites.
‣ If a tender operation is used, determine how many will be
needed to ensure a constant water supply.
72. Determining Type of Attack (1 of 3)
‣ Once the required fire flow has been determined, the
capability of available resources will determine the
strategy and tactics needed to control the incident.
‣ If the fire flow capability of available resources exceeds
the required fire flow, an interior attack on the fire can
usually be made.
73. Determining Type of Attack (2 of 3)
‣ Before this can be implemented, the Incident Commander
should consider:
‣ Do existing conditions allow sufficient safety for the
firefighters on an interior attack?
‣ Are there sufficient firefighters on scene?
‣ Is the fire area accessible?
‣ How many hose-lines and firefighters are needed?
‣ Where is the best location from which to attack the fire?
‣ What support activities are needed (ventilation, forcible
entry, etc.)?
74. Determining Type of Attack (3 of 3)
‣ If the fire flow requirements exceed the fire flow capability
