In the event of an oil fire, where is it safest to swim?

Swimming under an oil fire is believed to be the safest option because oil can act as a barrier between you and the flames. This is due to the fact that many types of oil do not mix readily with water, creating a layer on top of the surface. While there are inherent dangers in such a situation, such as the presence of toxic fumes or the risk of ignition, being submerged beneath the oil can provide some level of protection from direct exposure to flames and intense heat above the surface.

Swimming to the nearest shore could involve facing hazardous conditions related to the fire as well as potential burns or exposure to toxic smoke. Swimming on the oil surface poses a risk of ignition since the oil is flammable, making it potentially dangerous to remain there. Heading away from the vessel might seem like a logical choice, but it does not guarantee your safety from smoke or flames that could spread over a wider area.

Thus, being under the oil, while still risky, may offer some immediate protection from the flames, making it the safest option in a dire situation.
