Question 343Safety & Environmental - 1st Asst/Chief70% to pass
Drawings of your deck plans show the use of A60 bulkheads. "A" indicates which of the following?
AI Explanation
The correct answer is C) "A" class bulkheads must not allow flame or smoke passage for 60 minutes when subjected to a fire test.
The "A" in A60 bulkheads refers to the fire rating of the bulkheads, which is defined in the International Convention for the Safety of Life at Sea (SOLAS). According to SOLAS regulations, "A" class divisions, such as A60 bulkheads, must be capable of preventing the passage of flame and smoke for a minimum of 60 minutes when subjected to a standard fire test. This ensures that the bulkheads provide adequate fire protection and containment in the event of a fire on board.
The other options are incorrect because they do not accurately reflect the fire rating requirements for "A" class bulkheads as specified in the SOLAS regulations.
