Question 1010 Deck Safety

The correct answer is C) 51. The symbol for a fire main with fire valves on a Fire Control Plan is represented by the number 51. This is based on the standards and regulations set forth by the International Maritime Organization (IMO) and the U.S. Coast Guard for the graphical symbols used on fire control plans. The other answer choices do not correctly represent the fire main with fire valves symbol. Option A) 17 is the symbol for a fire extinguisher, option B) 34 is the symbol for a fire door, and option D) 56 is the symbol for a fire hydrant.
