TOOLS 1 AND 4 Flashcards
1) Of the following statements concerning the Department’s water extinguisher, which choice
reflects the most correct statements? (TB Tools 1-1, 2D, 4)
1. It has an operating pressure of 100 psi at 70 degrees F.
2. Water is expelled in 120 seconds.
3. In freezing weather, the extinguisher should be placed in an apparatus cab or other warm
area if the unit will be operating for an extended period.
4. There are two types of water extinguishers; those with a Schrader valve connected directly
to a valve handle and those with no Schrader valve.
5. The water extinguisher shall be hydrostatically tested at 1 year intervals or at any time it
shows evidence of corrosion or mechanical damage.
6. When operating the water extinguisher, direct the straight stream at the base of the fire. A
gloved finger placed lightly over the nozzle tip can help produce a fine spray which is often
useful at fires to obtain maximum cooling effect and extended the application time.
7. Using the extinguisher with a finger over the nozzle should only be used at very small or
smoldering fires where there is no detectable thermal draft created by the fire.
8. The pressurized water extinguisher shall be inspected daily and after each use.
A) 1,2, 3, 4, 5, 6
B) 1,3, 4, 6, 7, 8
C) 1,2, 3,4, 5, 6, 8
D) 1,3,4, 5, 8

2) Safety is an important part of routine maintenance. Of the following choices, which is
incorrect? (TB Tools 1 6)
A) Eye protection should be worn when recharging extinguisher.
B) Regulated extinguisher pressurization source should never be set higher than 100 psi.
C) Never stand directly in front of extinguisher gauge or stand over the valve during
pressurization.
D) The apparatus has a one way valve in the airline to prevent water from entering the brake
system.
B
3) The portable generator has many uses. A competent officer should know all of the
following to be correct with the exception of? (TB Tools 4 2.1, 2.3, 2.4, 3.8.1)
A) Portable generator lights in use by the Department utilize 500-watt lamps.
B) If generator lights fail to illuminate when power is applied, checkbulb for proper
connection.
C) If after checking the bulb connection the light fails to operate, replace with a new bulb.
D) If the light still fails to operate after replacing the bulb, open up the unit to ensure thereis
no fraying of the wires that supply the light.

4) Which choice below contains the most correct information regarding the various generators
Fire Department units employ? (TB Tools 4 3.5, 4.3, 4.6, 5.3, TB Tools 4 DS 1 1.2, 1.3, 4.4)
1. If a portable generator is used to power an exhaust fan, the ideal length of the electrical
cord should be ‘TOO feet” or less.
2. Apparatus with 12-gauge wire may encounter problems powering exhaust fans when the
length of the electric cord is greater than 50 feet.
3. Onboard generators shall be checked weekly during Multi Unit Drill.
4. Waterproof connections are good for use in up to “3 feet” of water when properly mated.
Care must be used when using all other connections near water.
5. Both Department-issued Honda portable generators have an approximate running time of
“4’/
2
hours.”
6. Operations requiring maximum power output should be limited to “60 minutes” for the
Honda portable generators.
