1. Dark gray or black smoke - ANSWER ____ venting under pressure from
structural seams, ridge/rim boards, eaves, and attic vents are a significant
indicator that heat and likely fire are present in that space.
2. Brownish smoke - ANSWER o Unfinished wood that is being rapidly
heated emits a —______ a collapse warning sign in lightweight wood
construction.
3. Incomplete combustion. - ANSWER _____ Materials contributing smoke
through incomplete combustion are actually on fire, but the rapid oxidation
hasn't fully reduced the fuel.
4. Pyrolitic decomposition - ANSWER Materials contributing smoke through
pyrolitic decomposition aren't necessarily burning but are being chemically
degraded by heat.
5. Pyrolysis - ANSWER (the shorter and more common term for pyrolitic
decomposition) is the chemical breakdown of compounds into other
substances by heat alone. Pyrolysis often leads to combustion.
,6. 10-to 90-second - ANSWER The explosive growth event (flame-over and
delayed flashover) is triggered by a volume shift between smoke and air that
occurs over a _____ time span, whereas the backdraft is instantaneous upon
the introduction of air to the oxygen-depleted environment.
7. Black fire - ANSWER is high-volume, has turbulent velocity, is ultra-dense,
and is deep black (in other words, smoke VVDC has gotten as bad as it can be).
Black fire is a sure sign of impending autoignition and flashover.
8. True - ANSWER True or False: Determining the appropriateness of risk-
taking (acceptable or unacceptable within defined criteria) is perhaps the most
important decision that the ISO has to make at the incident scene.
9. 1. Capturing current cues and clues. This level involves paying attention to what
is happening now.
2. Comprehending the situation. At this level, you make sense of what is
happening based on what you know and have experienced, or you acknowledge
that you haven't experienced this situation before.
3. Predicting the future. This level involves projecting what is likely or possible. -
ANSWER Dr. Gasaway suggests that there are three levels of SA:
9. Mental state, training, experience, and personal values. - ANSWER The
three (3) levels of SA are used to help you make risk/benefit decisions. Each
level is influenced by your
10.True - ANSWER T or F: Judgment regarding survivable spaces is perhaps
the toughest (and most speculative) one to render. In many ways, this
, judgment is the most important input to the acceptable/unacceptable risk-
taking decision.
11. Ground gradient - ANSWER is electrical energy that has established a
path to ground through the earth and is energizing it.
12. 30 feet (9 m) - ANSWER A downed power line may be energizing the
earth in a concentric ring of up to ___, depending on the voltage of the
source, especially if the ground is wet or snowy.
13. Step potential - ANSWER The electrical field gets weaker rapidly as the
distance from the point of entry increases. Therefore, there is a difference in
the potential voltages at any two points within the gradient. This potential
difference is known as ____.
14. 3 to 5 pounds - ANSWER Hazards associated with PV solar systems
include Additional roof dead load of ___per square foot. A standard 3-by-4-
foot PV panel weighs approximately 40 pounds.
15. 5 to 8 pounds - ANSWER Hazards associated with solar thermal systems
includes Additional roof dead load of____ per square foot
16. (up to 700 volts and 125 amps) - ANSWER Bright orange conduit or cable
can indicate that high-voltage power ___ is used in the drivetrain of a vehicle.
