  1. Question 1

    According to the Fire Safety Systems Code what is the maximum oxygen content permitted in the cargo tanks of an oil tanker?
    • 8 % by volume.
    • 3 % by volume.
    • 21 % by volume.
    • 11 % by volume.

  2. Question 2

    According to the Fire Safety Systems Code which one of the following would be considered a safe amount of oxygen in the output from an inert gas plant?
    • Less than 5 % oxygen.
    • Less than 11 % oxygen.
    • Less than 16 % oxygen.
    • Less than 21 % oxygen.

  3. Question 3

    According to the instructions in this module, which of these options would be carried out first when starting up a flue gas plant?
    • Open the boiler uptake valve.
    • Open the blower discharge valve.
    • Open the gas regulating valve.
    • Start the blower.

  4. Question 4

    If the inert gas at the blower outlet gets too hot a high temperature alarm is given. What will happen if the temperature of the gas continues to rise?
    • The inert gas blowers will stop and the gas regulating valve closes.
    • The backup scrubber water pump will be started automatically.
    • The inert gas will be vented to air until the temperature drops.
    • The temperature of the inert gas in the cargo tanks should be monitored every 15 minutes.

  5. Question 5

    In an oil cargo tank in which there is a mixture of hydrocarbon gas and air, which of the following is the best definition of the "Lower flammable limit" (LFL)?
    • It is the concentration of hydrocarbon vapour below which there is insufficient gas in the mixture to support combustion.
    • It is the point where the concentration of inert gas becomes too high to support combustion.
    • It is the point where the concentration of inert gas becomes too low to prevent combustion.
    • It is the point where the oxygen content becomes too high to support combustion.
