Question 1307 Deck General

The correct answer is C) no earlier than 24 hours prior to loading. According to the regulations for tank vessels, high level alarms and tank overfill alarms must be tested no earlier than 24 hours prior to loading the vessel. This ensures that the critical safety systems are functioning properly immediately before the loading operation, without being tested so far in advance that the alarms could potentially fail before the loading begins. Choices A and B are incorrect because they do not specify the 24-hour timeframe required by the regulations. Choice D is incorrect because the testing must be done no earlier than 24 hours prior to loading, not later.
