Oil Spill Quiz

According to the demonstration at the Cedre research center, which type of oil has the lowest viscosity and density?

• Heavy Fuel Oil

• Medium Crude Oil

• Bunker Oil

• Diesel

What is the approximate surface area that just one liter of diesel can cover when spilled on seawater?

• 10 square meters

• The size of a tennis court

• Up to a football pitch

• One square kilometer

Why is a physical cleanup operation rarely necessary for a diesel spill in the marine environment?

• It sinks to the bottom immediately.

• It is highly volatile and evaporates quickly into the atmosphere.

• It turns into a solid material upon contact with salt water.

• It is entirely consumed by fish within hours.

Approximately what percentage of a medium crude oil is typically composed of "light products" that will naturally evaporate?

• Less than 5%

• 10% to 15%

• 20% to 40%

• Over 75%

Which characteristic best describes Heavy Fuel Oil (Bunker Oil) during a spill?

• It spreads rapidly to form a thin, transparent sheen.

• It is highly volatile and disappears within minutes.

• It is very viscous, clings together, and persists as a semi-solid material.

• It has a high percentage (over 50%) of light components that evaporate.

Compared to diesel, how does the spreading behavior of heavy fuel oil differ?

• Heavy fuel oil spreads significantly faster due to its mass.

• Heavy fuel oil spreads very little, primarily remaining as a thick slick.

• Both oils spread at the exact same rate.

• Heavy fuel oil does not spread at all; it immediately dissolves.
