Class 'C' divisions are bulkheads and decks constructed of approved non-combustible materials that do not need to meet specific temperature rise limits or smoke and flame passage requirements required for A or B class divisions.

27. A cargo hold containing cargo such as nitrates, chlorates etc which produce oxygen under the influence of heat catches fire. How would you deal with this?

  • A. Close the hatches, apply boundary cooling and allow fire to use up the oxygen and extinguish itself
  • B. With this type of material, the hatches should not be battened down. The fire can only be extinguished using large quantities of water
  • C. Close the hatches and use the fixed CO2 system
  • D. Boundary cooling
Answer: B — With this type of material, the hatches should not be battened down. The fire can only be extinguished using large quantities of water
Cargoes such as nitrates and chlorates contain chemical oxidizers that produce oxygen when heated; smothering agents like CO2 are ineffective, so the fire must be fought using large quantities of water for cooling without battening down hatches.

28. The lowest temperature at which the heat from the combustion of a burning vapor is capable of producing vapor to enable combustion but not sustaining is:

  • A. Fire point
  • B. None of the above
  • C. Flash point
  • D. Ignition point
Answer: C — Flash point
The flash point is the lowest temperature at which a liquid fuel gives off sufficient vapor to form an ignitable mixture with air that momentarily flashes when an ignition source is introduced, but does not sustain combustion.

29. Which of the following statements is NOT correct about high expansion foam?

  • A. It has only a limited cooling effect.
  • B. You can survive in H.E. foam by breaking the bubbles to release the air.
  • C. You cannot survive in H.E. foam as the oxygen content is reduced.
  • D. It extinguishes by smothering.
Answer: C — You cannot survive in H.E. foam as the oxygen content is reduced.
High-expansion foam expands fresh air at ratios from 200:1 to 1000:1. The bubbles contain breathable air, so individuals trapped in high-expansion foam can breathe by parting bubbles away from their nose and mouth; stating that oxygen is reduced and survival is impossible is incorrect.
