STCW Firefighting Techniques 2

Question 1

When using a CO2 extinguisher in an enclosed space, what is the primary hazard to personnel?

Accepted Answer

Oxygen depletion creating an asphyxiation risk

Answer

CO2 displaces oxygen in enclosed spaces, creating a life-threatening asphyxiation hazard for anyone inside.

Question 2

In the STCW framework, what does 'boundary cooling' refer to during a shipboard fire?

Accepted Answer

Applying water to bulkheads and decks adjacent to the fire to prevent heat spread

Answer

Boundary cooling prevents heat transfer through steel structures, stopping fire spread to adjacent compartments.

Question 3

Which class of fire involves energized electrical equipment?

Accepted Answer

Class C

Answer

Class C fires involve energized electrical equipment and require non-conductive extinguishing agents.

Question 4

A fire team member notices the fire is in a liquid cargo hold. Which extinguishing agent is MOST appropriate?

Accepted Answer

Dry powder or foam

Answer

Foam smothers flammable liquid fires by blanketing the fuel surface and preventing vapor release, while dry powder interrupts the chemical chain reaction.

Question 5

What is the purpose of a 'fire patrol' as required by SOLAS?

Accepted Answer

To conduct regular rounds to detect fire or smoke early
