  • Patent number: 7004806
    Abstract: A rescue flotation buoy integrated with a pressurized containment and dispensing device containing a pressurized repellent for sharks. Sodium lauryl sulfate, a well-known shark repellent, is one such material that could be utilized. The repellent material can be dispensed more than one time by the use of a valve connected to the containment and dispensing device. The integration of a rescue flotation buoy and a shark repellent will allow rescue personnel to repel sharks when saving a victim of a shark attack. The purpose is to expose the predator to an immediate high concentration of the appropriate repellent, thereby diverting the predator from its attack. Subsequent applications of the shark repellent can also be performed.
