Booms -- Floating barriers placed around the oil or around whatever is leaking the oil. Booms contain the oil so skimmers can collect it.
Skimmers -- Boats, vacuum machines, and oil-absorbent plastic ropes that skim spilled oil from the water's surface after booms have corralled it. The skimmer collects oil into a container so it can be removed.
Chemical dispersants -- Materials that break down the oil into its chemical constituents. This helps disperse the oil and make it less harmful to wildlife and shorelines.
In-situ burning -- Igniting freshly spilled oil while it's still floating on the water.
