A boom containment is a temporary floating barrier used to contain oil spills. Booms are used to reduce the possibility of coastlines and other resources, and help recovery easier. The boom helps concentrate the oil on a thicker surface layer so that skimmers, vacuums, or other collection methods can be used more effectively. They come in different shapes and sizes, with varying degrees of effectiveness in different types of water conditions.
Often the first detention methods used and the last equipment to be removed from oil spill locations, they are "the most commonly used and most environmentally friendly response technique to clean up oil spills in the United States."
Booms used in oil spills can be seen when they rest on the water surface, but can have between 18 and 48 inches of material that hangs below the surface. They are effective in calm water, but because high waves increase oil or other contaminants can easily moisten the top of the boom and render them useless.
In any oil spill, the use of a conventional boom is not effective in protecting environmental resources even with correct concept and aspect ratios. For speeds of more than 1 knot (water and hence oil), booms will fail to stop the oil due to drainage below the boom. The approaching oil must be slowed before it meets the boom. Drainage failure can be avoided by using a series of well-designed booms.

Tactics
- Containment boom: placing a boom in contaminated water bodies for the purpose of withholding or slowing the movement of contamination.
- Booming diversion: placing an explosion inside the body of contaminated water for the purpose of transferring contamination to the point of collection.
Boom spikes: placing booms in water bodies for the sole purpose of changing the course of contamination. This method is used for contamination not intended to be recovered and not related to oil spills.
Booming exceptions: placing booms in water bodies for the purpose of blocking sensitive areas from contamination. This is not recommended in fast water, and as boom diversion or boom deflection is more suitable. However, when boominh booming and deflection tactics are not appropriate and resource protection is still needed, such as because of rapid tides at sensitive estuaries, boom setting with deselerators is required.
