Question 139Safety & Environmental - 1st Asst/Chief

The correct answer is D) booms. Booms are the most common type of containment device used to control and contain spilled oil on the water. Booms are floating barriers that are deployed around the spill to prevent the oil from spreading and to concentrate it in one area, making it easier to collect and remove. This is in accordance with Coast Guard regulations and industry best practices for oil spill response. The other options are not the most commonly used containment devices. Skimmers are used to physically remove the oil from the water's surface, chemical dispersants are used to break up the oil into smaller droplets, and straw is not a primary containment method for oil spills on water.
