Description:Dispersants are being used in the Deepwater Horizon (Gulf of Mexico) response to remove oil from the surface of water where it can be especially harmful to the environment. The National Institute for Occupational Safety and Health (NIOSH) has prepared this document to guide workers involved in these efforts on ways to protect themselves from potential exposures. This fact sheet will be updated as new information on the types of dispersants being used in the response is received.
Dispersants are usually applied directly to the spilled oil by spraying from an airplane, helicopter, or vessel. Although dispersants are manufactured by many companies and their ingredients may differ, most contain a detergent and a solvent. The solvent allows the detergent to be applied. The detergent helps to break up the oil on the water surface into very small drops. These tiny oil drops are then able to easily mix with the water and be diluted.
