  • 1

    What is the color code for fire extinguisher lines?

    Brown

    Which fire-extinguishing agent is considered to be the least toxic?

    Bromotrifluoromethane (Halon 1301)

  • 3

    What method is used to detect the thermal discharge of a built-in fire extinguisher system?

    A rupture of the red plastic disk in the thermal discharge line

  • 4

    A fire extinguisher cartridge is removed from a discharge valve, it should be

    used only on the original discharge valve

  • 5

    Smoke detection instruments are classified by their method of

    detection

  • 6

    Maintenance of fire-detection systems include the

    Replacement of damaged sensing elements

  • 7

    Smoke in the cargo and/or baggage compartment of an aircraft is commonly detected by which instrument?

    Photoelectric cell

  • 8

    The proper fire-extinguishing agent to use on an aircraft brake fire is

    dry powder chemical

  • 9

    Smoke detectors which use a measurement of light transmissibility in the air are called

    Photoelectrical devices

  • 10

    Which fire-detection system measures temperature rise compared to a reference temperature

    Thermocouple

  • 11

    What occurs when a visual smoke detector is activated?

    A lamp within the indicator illuminates automatically

  • 12

    A contaminated carbon monoxide portable test unit would be returned to service by

    installing a new indicating element

  • 13

    A squib, as uaed in a fire protection system, is a

    device for causing the fire extinguishing agent to be released

  • 14

    When used in fire detection systems having a single indicator light, thermal switches are wired in

    parallel with each other and in series with the light

  • 15

    On a periodic check of fire extinguisher containers, the pressure was not between minimum and maximum limits. What procedure should be followed?

    Replace the extinguisher container

  • 16

    Which of the following are fire precautions which must be observed when working on an oxygen system?

    Display 'No Smoking' placards Provide adequate fire-fighting equipment Keep all tools and oxygen servicing equipment free from oil or grease Avoid checking aircraft radion or electrical system

  • 17

    The thermal switches of a bimetallic thermal-switch type fire detection (single-loop) system are heat-sensitive units that complete circuits at a certain temperature. They are connected in

    parallel with each other, but in series with the indicator lights

  • 18

    Why does the Fenwal fire-detection system use spot detectors wired parallel between two separate circuits?

    A short may exist in either circuit without causing a false fire warning

  • 19

    In some fire-extinguishing systems, evidence that the system has been intentionally discharged is indicated by the absence of

    yellow disk on the side of the fuselage

  • 20

    A fire-extinguisher container can be checked to determine its charge by

    weighing the container and its content

  • 21

    The types of fire-extinguishing agents for aircraft interior fires are

    water, carbon dioxide, dry chemical, and halogenated hydrocarbons

  • 22

    In what area of an aircraft would you find a carbon monoxide detector?

    Cockpit and/or cabin

  • 23

    A carbon dioxide (CO2) hand-held fire extinguisher may be used on an electrical fire if the

    horn is nonmetallic

  • 24

    When air samples contain carbon monoxide, portable carbon monoxide detectors containing yellow silica gel will turn which color?

    Green

  • 25

    A thermocouple in a fure-detection system causes the warning system to operate because

    it generates a small current when heated

  • 26

    Light refraction smoke detectors are actived when the detector

    senses light reflected from smoke particles passing through a chamber

  • 27

    The thermocouple fire-warning system is activated by

    Rate-of-temperature rise

  • 28

    Built-in aurcraft fire-extinguishing system are ordinarily charged with

    halogenated hydrocarbons and nitrogen

  • 29

    The most common cause of false fire warnings in continuous-loop fire detection systems is

    dents, kinks, or crushed sensor sections

  • 30

    In reference to aircraft fire-extinguishing systems, (1) during removal or installation, the terminals of discharge cartridges should be grounded or shorted (2) before connecting cartridge terminals to the electrical system, the system should be checked with a voltmeter to see that no voltage exists at the terminal connections.

    Both no.1 and no. are TRUE
