Which type of container breach is most associated with B-Runaway cracking
BLEVE?
A-tear
B-runaway cracking
C-puncture
D-disintegration
If gas is burning at an incident involving underground Not D.
pipelines:
A-the flame should not be extinguished
B-the flame should be extinguished
C-the area should be blanketed with foam
D-responder should attempt to shut off the gas supply
first
,An effective foam blanket produces uniform size bubbles B- Aeration
through:
A-separating
B-aeration
C-expansion
D-proportioning
Which type of fire stream can be used for crew protection A-fog stream
when advancing to shut off liquid or gas control?
A-fog stream
B-broken stream
C-solid stream
D-straight stream
, Flammable liquids have flashpoints below 100°F which C - Can be ignited without being preheated
means they:
A-are also combustible
B-must be heated above their flashpoint before they can
be ignited
C-can be ignited without being preheated
D-well displace any foam that is applied
At roadway, incidents involving bulk transport fires, B-determine the exact nature of cargoes as soon as possible
firefighters should:
A-direct runoff of contaminated water and spilled liquid
liquids into storm drains
B-determine the exact nature of cargoes as soon as
possible
C-use road flares to alert that there is a traffic incident
D-avoid apply host streams until law-enforcement has
cleared the scene
