Freezing salt water spray should be anticipated when the air temperature drops below what temperature?
AI Explanation
The correct answer is B) 28°F (-2.2°C).
Freezing salt water spray can be anticipated when the air temperature drops below 28°F (-2.2°C). This is because saltwater has a lower freezing point than freshwater due to the presence of dissolved salts. The freezing point of seawater is typically around 28°F (-2.2°C), so at air temperatures below this, the water spray on the vessel can start to freeze, creating a hazardous condition.
The other options are incorrect because 0°F (-17.8°C) is too low, 32°F (0.0°C) is the freezing point of freshwater, not saltwater, and -40°F (-28.9°C) is an unrealistically low temperature for most maritime environments.
