Which of the following is a common source of fire hazards in the galley of a ship?

Open flames while cooking are indeed a common source of fire hazards in the galley of a ship. The galley, being a space where food is prepared, often involves the use of stoves, ovens, and grills, all of which utilize open flames or high heat to cook food. These flames pose a significant risk if they come into contact with combustible materials, such as cooking oils, paper towels, or food packaging, which can ignite easily.

In a confined space like a ship's galley, the potential for a fire to spread quickly is heightened due to limited exits and enclosed environments. Additionally, the combination of fats and oils used in cooking can create a dangerously flammable situation. Therefore, proper fire safety protocols, such as maintaining clear cooking areas, regular cleaning to prevent grease buildup, and immediate response to any flames, are critical to ensuring the safety of everyone on board.

The other options, while they may pose some level of risk, are less directly related to the typical fire hazards encountered during cooking operations in a galley environment.
