what do you do?.
Answer: Take the truck out of service
◍ What class of traffic vest is required with PPE?.
Answer: Class 2
◍ Adjustable Fog Nozzle.
Answer: Straight StreamNarrow FogWide FogAll 3 discharge at a rate of
100 gpmThe wider the pattern, the shorter the time span to fill a room with
steam.
◍ Advantages of Water.
Answer: 1. Can absorb large amounts of heat2. As surface area increases,
heat absorption increases3. Water is plentiful in most areas4. Steam
occupies 1,700 times its original volume as water
◍ Disadvantages of Water.
Answer: 1. High surface tension limits its penetration into dense materials2.
Incompatible with or reactive to certain fuels and combustible materials3.
Ice makes roofs and ladders slippery and can make equipment malfunction
4. Conducts electricity and makes work with energized electrical equipment
, dangerous
◍ Water Pressure.
Answer: The force of water per unit area
◍ PSI.
Answer: pounds per square inchThe elevation of water defines psiColumn of
water = 1 in x 1 in x 12 in = 0.434 psiHeight determines psi
◍ 6 Characteristics of Water.
Answer: BED PADBottomEqualDepthPerpendicular AllDensity
◍ What should be used when reversing an apparatus?.
Answer: A spotter
◍ Bottom.
Answer: The pressure at the bottom is independent of the shape of the liquid
container above it
◍ Equal.
Answer: The pressure transmitted to a confirmed amount of water is
transmitted equally in all directions
◍ While driving, a firefighter removes his seatbelt, what should you do?.
Answer: Slow down and stop until his seatbelt is on
◍ Depth.
Answer: The pressure of water in an open container is proportional to its
depth
◍ Perpendicular.
Answer: The pressure on an amount of water is perpendicular to any surface
it acts on
◍ How do you proceed through a red light during an emergency?.
Answer: Leave sirens on, stop and proceed with caution
◍ All.
Answer: At any point in the water in a container, pressure is equal in ALL
