Question 1

Fire

Answer 1

gas phase chemical reaction resulting in the evolution of heat and light

Question 2

oxidizer

Answer 2

a chem that is mixed with fuel to enable burning

Question 3

heat

Answer 3

a form of energy measured in joules needed to increase temp of the fuel, to cause ignition and promote fire growth

Question 4

heat release rate

Answer 4

rate at which thermal energy is generated by burning

Question 5

3 forms of heat transfer

Answer 5

conduction: solids
convection: liquid or gas
radiation: electromagnetic waves

Question 6

pyrolysis

Answer 6

chem decomposition of a compound into one or more substance due heat alone

Question 7

ignition

Answer 7

moment when self sustained combustion has started

Question 8

solids and liquids dont burn T/F

Answer 8

T

only gases

Question 9

smoke

Answer 9

mixture of airborne solid and liquid particulates and gases which are generated in pyrolysis

Question 10

fuel limited fire

Answer 10

heat release rate is limited by fuel

Question 11

ventilation limited fire

Answer 11

heat release rate is limited by oxygen

Question 12

flow path

Answer 12

consists of areas within a structure where heat, smoke, and air flows from an area of higher pressure to lower pressure

Question 13

flow path has these 3 componets

Answer 13

intake vent, exhaust vent and connecting volume between vents

Question 14

3 types of flow path

Answer 14

uni-directional: only in or out
bi-directional: single vent both intake and exhaust
neutral plane: interface or level of zero differential pressure a compartment vent

Question 15

possible fire location if:
no smoke at door level
mid neutral plane
smoke to floor

Answer 15

above you
same floor
below you

Question 16

super heated gases

Answer 16

“black smoke” fuel but not enough oxygen
