Boom (containment)

A containment boom is a temporary floating barrier used to contain an oil spill. Booms are used to reduce the possibility of polluting shorelines and other resources, and to help make recovery easier. Booms help to concentrate oil in thicker surface rather than disperse across larger areas.^[1]

Tactics

• Containment booming: placing a boom in a body of contaminated water for the purpose of holding or slowing the movement of contamination.^[2]
• Diversion booming: placing a boom in a body of contaminated water for the purpose of diverting the contamination to a collection point.^[3]
• Deflection booming: placing a boom in a body of water for the sole purpose of changing the course of the contamination. This method is used for contamination that is not intended to be recovered and so is not typically associated with oil spills.^[4]
• Exclusion booming: placing a boom in a body of water for the purpose of blocking off a sensitive area from contamination. It is not recommended in fast water, and as diversion booming or deflection booming is better suited.^[5] However, when diversion booming and deflection booming tactics are not suitable and resource protection is still needed, like because of a fast high tide in a sensitive estuary, an arrangement of booms with a decelerator is needed.^[1][6]
