patterns (often V shaped)
Ventilation generated patterns
Hot gas layer patterns (Line of demarcation)
What is spalling? ✔Correct Answer-The separation of chunks of concrete with explosive force caused by the
expansion of water (moisture) trapped in the concrete as it turns to steam
What is char? ✔Correct Answer-Pyrolized carbonaceous material
What is oxidation? ✔Correct Answer-Physical change in appearance of a material resulting from the
combination of oxygen.
What is alloying? ✔Correct Answer-Mixing two metals heated then cooled to change their properties. Often
melts at a lower temperature.
What is a clean burn? ✔Correct Answer-When there was enough heat to burn away all carbon deposits (soot)
on a surface leaving a "clean" surface. Occurs on non-combustible surfaces.

What is compartmentation? ✔Correct Answer-Design features of a building that limit fire growth to the room
of origin.
What are the five building construction types? ✔Correct Answer-Type I - Fire resistant
Type II - Non combustible

houses.
What is platform frame construction? ✔Correct Answer-Each floor is a seperate platform.
,What is balloon frame construction? ✔Correct Answer-The wall studs extend from the foundation to the roof.
What is Ohm's Law? ✔Correct Answer-V=IR
(E = I x R)
What is voltage? ✔Correct Answer-Pressure
What is current? ✔Correct Answer-Flow
What is resistance? ✔Correct Answer-Friction, opposition to the flow
What is an overload? ✔Correct Answer-Power needs exceed the circuit's capacity.
Alternating Current VS Direct Current ✔Correct Answer-Alternating current - the electrons flow out from the
source and then back to it, alternating directions.
Direct current - electrons flow one way.
Single Phase service ✔Correct Answer-Residential. Three conductors: Two insulated conductors at 120 V
each, and a bare ground wire.
Three phase system ✔Correct Answer-Commercial. Four conductors: Three insulated conductors (480, 240, or
208 V), and a bare ground wire.
What is the difference between grounding and bonding? ✔Correct Answer-Grounding connects the system to
the earth (ground). Bonding connects to systems together so the charge stays the same between them.
What is overcurrent protection? ✔Correct Answer-A device that protects the system from excess current.
Includes:
Circuit breakers
Plug fuses
Type S fuses
Time delay fuses
Cartridge fuses
What are the colors of residential wires? ✔Correct Answer-Hot - black or red
Neutral - gray or white
Ground - bare or green
What are some methods of electrical heat production? ✔Correct Answer-Resistance heating
Short circuit
Ground fault
Parting Arc
Excessive current
What is the difference between and arc and a spark? ✔Correct Answer-Sparks are thrown metal particles
Arcs are brief discharges of electricity
What is arc tracking? ✔Correct Answer-Arc following salts, dusts, or liquids along a path.
What is arc mapping? ✔Correct Answer-Mapping out of electrical damage in a circuit.
, What is static electricity? ✔Correct Answer-A stationary charge caused by movement of one object against
another. Lighting is a static disharge.
What are the five conditions nessecery for Static Arc Ignition? ✔Correct Answer-A Means of static generation
A means of accumulating and maintaining the charge
A static discharge with sufficient energy
A fuel source
Coexistence of the arc and fuel source
Name two fuel gasses: ✔Correct Answer-LP (liquid petroleum)
Natural gas
What is the difference between tanks and cylinders for LP gas? ✔Correct Answer-Tanks: storage with greater
than 1000 LBs water capacity.
Cylinder: Portable, usually consumer.
What are some human factors related to fire initiation in a structure? ✔Correct Answer-Improper
maintenance and operation
Housekeeping
Product labels, warnings, and instructions
Recalls
Violations of fire safety codes and standards
What are the age groups and types of child firesetters? ✔Correct Answer-Child 2-6, curiosity
