Answer: D
According to Jones & Bartlett’s Fire Department Incident Safety Officer, hostile event warning signs that include: dense smoke that appears to have totally filled a building (floor to ceiling), smoke that rapidly speeds up when an exterior door is opened, and exhaust flow paths that intermittently puff or try to suck air would indicate:
A) Flashover
B) Explosive growth phase
C) Backdraft
D) Smoke explosion
B) Explosive growth phase
Answer: B
According to Jones & Bartlett’s Fire Department Incident Safety Officer, hostile warning event signs that include: turbulent smoke flow that has filled a compartment, vent-point ignition and a rapid change in smoke volume and velocity (getting worse in seconds) would indicate a:
A) Flashover
B) Explosive growth phase
C) Backdraft
D) Smoke explosion
A) Flashover
Answer: A
According to Jones & Bartlett’s Fire Department Incident Safety Officer, ____________ occurs when smoke reaches sustaining temperatures that are above the fire point of prevalent gases. The gases can suddenly ignite when touched by an additional spark or flame. Fire spread changes from flame contact across content surfaces to fire spread through the smoke. This hostile event is known as a:
A) Flashover
B) Backdraft
C) Flame-over
D) Smoke explosion
C) Flame-over
Answer: C
According to Jones & Bartlett’s Fire Department Incident Safety Officer, ___________ occurs when oxygen is introduced into a closed, pressurized space where fire products are above their ignition temperature. This hostile event is known as a:
A) Flashover
B) Backdraft
C) Flame-over
D) Smoke explosion
B) Backdraft
Answer: B
According to Jones & Bartlett’s Fire Department Incident Safety Officer, ____________ occurs when a spark or flame is introduced into trapped smoke that is below its ignition temperature but above its flashpoint. This hostile event is known as a:
A) Explosive growth phase
B) Backdraft
C) Flame-over
D) Smoke explosion
D) Smoke explosion
Answer: D
According to Jones & Bartlett’s Fire Department Incident Safety Officer, _____________ occurs when air is introduced to a ventilation-limited fire. It can include smoke flame-over in flow paths and flashover of individual rooms that are heat saturated. This hostile event is known as:
A) Explosive growth phase
B) Backdraft
C) Flame-over
D) Smoke explosion
A) Explosive growth phase
Answer: A
According to Jones & Bartlett’s Fire Department Incident Safety Officer, occurs when radiant heat reflected within a room or space. All surfaces reach their ignition temperature at virtually the same time due to rapid heat buildup in the space. This hostile event is known as:
A) Flashover
B) Explosive growth phase
C) Backdraft
D) Flame-over
A) Flashover
Answer: A
According to Jones & Bartlett’s Fire Department Incident Safety Officer, which of the following about smoke characteristics is incorrect?
A) The thicker the smoke, the more explosive it is
B) Faster smoke is further from the seat of the fire
C) Fire that emits very little visible smoke is hot, well ventilated and clean-burning D) Black smoke indicates hot smoke, regardless of material involved
B) Faster smoke is further from the seat of the fire
Answer: B
According to Jones & Bartlett’s Fire Department Incident Safety Officer, which of the following about smoke characteristics is incorrect?
A) Thick black smoke in a compartment reduces the chance of life sustainability
B) Smoke can either be turbulent or laminar
C) Smoke cannot be used to help find the location of the fire in a building
D) Smoke follows the path of least resistance
C) Smoke cannot be used to help find the location of the fire in a building
Answer: C
