The ventilation system of your ship has fire dampers restrained by fusible links. Which statement is TRUE?
AI Explanation
The correct answer is C) Fusible links must be replaced if a damper is activated.
This is correct because when a fusible link is exposed to heat and melts, it triggers the fire damper to open, breaking the link. Once the link has been melted, it needs to be replaced to restore the proper function of the fire damper system. The other link cannot simply be reset after a fire is extinguished.
The other options are incorrect because A) the link does not automatically reset after a fire, B) the links do not need to be replaced at every inspection unless they have been activated, and D) while testing the links by applying heat is a valid method, it is not required to replace them simply due to the testing.
