RCW 46.61.035 (4) authorized emergency vehicles responding to a call to break laws that apply to other
drivers but does not relieve the driver from the duty of driving with _______ regard for the safety of all
persons. - correct answer ✔✔Due
TRUE or FALSE:
When a pump is supplying multiple lines, any sudden change in flow in one line ca cause a drastic and
dangerous change in another. To combat this, automatic pressure regulators are needed to ensure the
safety of all personnel T - correct answer ✔✔TRUE
What is the first action in a SCBA emergency? - correct answer ✔✔Immediately notify their partner to
assist.
Pressure relief valve - correct answer ✔✔Device relieves excess pressure.
Pressure Regulator - correct answer ✔✔Device designed to regulate engine speed (RPM) to match
discharge pressure.
True or False:
Lightweight construction may collapse earlier in the incident and without warning and - correct answer
✔✔TRUE
Chemical-pellet sprinkler head - correct answer ✔✔A sprinkler head activated by a chemical pellet that
liquefies at a preset temperature.
, Frangible Bulb - correct answer ✔✔Small glass vial fitted into a detector or sprinkler. The glass vial is
partly filled with a liquid that expands as heat increases. At a predetermined temperature, vapor
pressure causes the glass bulb to break, which activates the device.
Fusible Link - correct answer ✔✔Connecting link device that fuses or melts when exposed to heat; used
in sprinklers, fire doors, dampers, heat detectors, and ventilators.
Indicator(s) of potential back draft?
A) Turbulent Smoke
B) Puffing of smoke
C) Air being drawn into building with zero visibility
D) Blacken Windows - correct answer ✔✔All of the above
Gauge(s) that measure positive pressure or vacuum? - correct answer ✔✔Intake, Vacuum, Compound
gauges
Mechanical device installed in a discharge line that senses the amount of water flowing. - correct answer
✔✔Flow Meter
What is the friction loss of a master stream appliance? - correct answer ✔✔25
Methods for rescuing a person from the water, lowest risk first? - correct answer ✔✔Reach, Throw, Row,
Go
Two basic pressurized water supply sources? - correct answer ✔✔Hydrant and another engine
abandon - correct answer ✔✔Leave equipment in-place and exit hazard zone as quick and safely as
possible.
Withdraw - correct answer ✔✔Exit the structure orderly and with equipment.
