The ventilation system of your ship has fire dampers restrained by fusible links. Which statement is TRUE?

Correct Answer: Option C — Fusible links must be replaced if a damper is activated.

Fusible links rely on a solder alloy designed to melt at a specific temperature during a fire. Once fused and the damper releases, the link undergoes structural deformation and cannot be reused, requiring complete replacement to restore fire boundary integrity.
