Structural FF initial Response Strategy And Tactics

Question 1

What is an oxidizer

Answer 1

It is commonly oxygen oxidizers are not combustible but will support or enhance combustion. Is a chemical reaction involving the combustion of and oxidize or such as oxygen in the air with other materials.

Question 2

Energy

Answer 2

Is the capacity to perform work

Question 3

Types of energy

Answer 3

Classified as either potential or kinetic potential energy represents the amount of energy than an object can release at some point in the future Kinetic energy is the energy that a moving object possesses

Question 4

Heat of combustion

Answer 4

The potential energy available for release in the combustion process is known as heat of combustion the rate at which a fuel releases energy over time depends on many variables including chemical composition arrangement density of the fuel availability of oxygen for combustion

Question 5

Thermal energy

Answer 5

Kinetic energy associated with the random motions of the molecules of a material or object often use interchangeably with the terms he and heat energy

Question 6

Types of energy

Answer 6

Chemical thermal mechanical electrical light nuclear and sound

Question 7

Exothermic reactions

Answer 7

Reactions that emit energy as they occur fire is an exothermic chemical reaction that releases energy in the form of heat and sometimes light

Question 8

Endothermic reactions

Answer 8

Reactions that absorb energy as they occur for example converting water from liquid to a gas steam requires the input of energy resultant in that reaction

Question 9

Fire tetrahedron

Answer 9

Reducing agent fuel oxidizing agent chemical chain reaction and heat

Question 10

Pyrolysis

Answer 10

In solids off gassing is a chemical change known as pyrolysis. in liquids a physical change call vaporization

Question 11

Piloted Ignition

Answer 11

Is the most common form of Ignition in occurs when a mixture of fuel and oxygen encounter in external heat source with sufficient heat or thermal energy to start the combustion reaction

Question 12

Auto Ignition

Answer 12

Occurs without any external flame or spark to ignite the fuel gasses or vapors

Question 13

Auto Ignition temperature

Answer 13

Minimum temperature at which a fuel in the air must be heated in order to start self sustain combustion that temperature is always higher than its piloted Ignition temperature

Question 14

Non flaming combustion

Answer 14

Occurs more slowly in at a lower temperature producing a smoldering glow in the material surface. An example of this is charcoal

Question 15

Flaming combustion

Answer 15

Is commonly refer to as fire it produces a visible flame above the material surface flaming combustion occurs when a gaseous fuel mixes with oxygen in the correct ratio and heats to Ignition temperature

Question 16

Products of combustion

Answer 16

Simply described as he in smoke

Smoke is the product of incomplete combustion combustion is incomplete when any of the fuel is left after combustion has occurred

Question 17

CO

Answer 17

Is a Chemical asphyxiant That decreases blood’s ability to carry oxygen
CEO combines with hemoglobin about 200 times more efficiently than oxygen

Question 18

Hydrogen cyanide

Answer 18

Materials are found in upholstered furniture bedding insulation carpets clothing other building materials and household items Create hydrogen cyanide when burned

Question 19

Hydrogen cyanide facts

Answer 19

How do jin cyanide is a by-product of the combustion of polyurethane foam used in many household furnishings
HCN is 35 times more toxic than Co
It can be inhaled absorbed in jested and attacks the heart and brain

Question 20

Carbon dioxide

Answer 20

Is a product of complete combustion it displaces existing oxygen which creates an oxygen deficient atmosphere also acts as a respiratory stimulant increasing respiratory rate

Question 21

Smoke facts

Answer 21

More than 20 irritants in smoke have been identified including hydrogen chloride formaldehyde in a acrolein
