Mini-Booms are a selective sorbent which will sorb hydrocarbon-based liquids (oleophilic) and repel aqueous-based liquids (hydrophobic). Mini-booms are typically used because of their tube-like shape to encircle spills and contain leaks. A 3 inches diameter scrim on the outside of the boom identifies the use while containing particulate sorbent material. The T-4 mini-boom is 4 feet in length. A case weighs 12 pounds.
