The premixed foam agent in fixed and semiportable fire extinguishing systems should be replaced (small passenger vessel regulations)
AI Explanation
The correct answer is C) every 36 months.
The small passenger vessel regulations stipulate that the premixed foam agent in fixed and semiportable fire extinguishing systems should be replaced every 36 months. This is to ensure the agent remains effective and in good condition to properly function in the event of a fire.
The other options are incorrect because 18 months (A) and 12 months (B) are too frequent for replacement, while only replacing when used (D) does not account for gradual degradation of the foam agent over time, even if the system has not been activated.
