smoke - ANSWER ✓ the products of incomplete combustion and pyrolysis; it
includes an aggregate of particles, aerosols, and fire gases that are toxic,
flammable, and volatile
smoke explosion - ANSWER ✓ a hostile fire event that occurs when a spark or
flame is introduced into a pocket of smoke that is below ignition temperature but
above some aggregate flashpoint. the result is a split second ignition and rapid
expansion of that pocket with no sustained burning
turbulent smoke filling a box - ANSWER ✓ warning sign of impending flashover
thick black fast smoke - ANSWER ✓ close to the seat of the fire, super hot smoke
capable of instant ignition. may be a ventilation controlled fire needing air
thin black fast smoke - ANSWER ✓ flame pushed smoke; fire nearby that is well
ventilated
dirty white smoke with velocity - ANSWER ✓ heat pushed smoke that has
travelled a distance or has had the carbon filtered (like through a crack)
same color smoke and same velocity from multiple openings - ANSWER ✓ deep
seated fire, possibly located well within a building or in combustible void and
concealed spaces
,low volume white smoke from more than one location of a large building -
ANSWER ✓ working fire deep within
brown smoke - ANSWER ✓ unfinished wood reaching late heating (can support
flame) usually a sign that contents fire is transitioning into a structure fire. when
coming from structural spaces of lightweight wood structures its a warning sign of
collapse
yellowish gray smoke from cracks or seams - ANSWER ✓ sulfur compounds, a
warning sign of impending backdraft
warning signs- smoke explosion - ANSWER ✓ increasing pressure in trapped
smoke away from a growing fire (room above, dead end hallways, stairways, etc)
warning signs- flame over - ANSWER ✓ ghosting, smoke flow paths that are
moving faster than firefighters can crawl
warning signs-flashover - ANSWER ✓ turbulent smoke that has filled a room,
ghosting, exterior vent point ignition
warning signs- explosive growth - ANSWER ✓ (flame over and flashover)
puffing and sucking of smoke at open doors and windows, ghosting
warning signs- backdraft - ANSWER ✓ closed pressurized box with signs of
extreme heat, puffing and sucking of smoke at cracks and seams, yellowish/gray
smoke
recognition primed decision making (RPD) - ANSWER ✓ a mental model that
suggests that many quick decisions are made using mental templates from previous
experiences that fit the images you are currently witnessing
situational awareness - ANSWER ✓ the degree of accuracy to which one's
perception of his or her current environment mirrors reality
valued property - ANSWER ✓ physical property whose loss will cause harm to
the community
, vicarious learning - ANSWER ✓ the process of observing others to develop
knowledge skill or experience base
acclimation - ANSWER ✓ an individual's gradual process of becoming
accustomed to an environment
accommodation - ANSWER ✓ the efforts to alter or adjust the environment,
worker relationship, or task to reduce injury potential
active cooling - ANSWER ✓ the process of using external methods or devices to
reduce elevated body core temperatures
atypically stressful incident - ANSWER ✓ an incident that involves an unusually
gruesome situation, serious firefighter injury, firefighter death, or other potential
psychological stress
circadian rhythm - ANSWER ✓ a person's physiological response to the 24 hour
clock, which includes sleep, energy peaks, and necessary body functions
ergonomics - ANSWER ✓ the science of adapting work or working conditions to
a worker and the study of problems associated with people adjusting to their work
environment
passive cooling - ANSWER ✓ the use of shade, air movement, and rest to bring
down core temperatures
transient heat fatigue (THF) - ANSWER ✓ an early warning sign that the core
temperature is elevated, as characterized by the onset of physical exhaustion that is
remedied by rest and hydration only to return quickly and more profoundly upon
engagement with the hot environment
work hardening - ANSWER ✓ efforts to improve an individual's strength,
flexibility, and aerobics to help prevent overexertion at incidents
firm intervention - ANSWER ✓ a direct order to immediately stop, alter, suspend,
or withdraw personnel, activities, and operations due to an imminent threat
