Deepwater Horizon Response Air Sampling Data

The April 20, 2010, explosion and collapse of the BP Deepwater Horizon oil platform in the Gulf of Mexico resulted in the release of millions of barrels of oil into Gulf waters. The response to this disaster involved the efforts of tens of thousands of workers in a variety of capacities across Louisiana, Mississippi, Alabama, Florida, Texas, and in the Gulf of Mexico itself. The diverse work included oil and tar ball removal from beaches, oil skimming and booming near shores, burning of surface oil near the source of the oil release, surface application of dispersant by vessels and aircraft, and containment and recovery work on vessels at the release site. The nature of these activities raised concerns about potential occupational exposures to chemical and physical hazards and mental stressors. NIOSH investigators conducted health hazard evaluations (HHEs) of Deepwater Horizon Response onshore and offshore workers. The goals of the NIOSH HHE assessments were to describe acute health effects, evaluate occupational exposures in qualitative or quantitative assessments, and generate hypotheses regarding symptoms potentially related to work activities. Environmental air samples were collected in support of the goals. NIOSH investigators conducted the following exposure evaluations: - We conducted evaluations on board vessels releasing dispersant. These vessels were deployed to perform small‐scale releases of dispersant in an area with surface oil contamination. - We assessed exposures during in‐situ (i.e., on site) burns of surface oil. - We assessed exposures on fishing and shrimping trawlers in the Vessels of Opportunity (VoO) program that were assigned to remove surface oil by booming and skimming. - We assessed exposures aboard vessels located at the Deepwater Horizon incident site. - We assessed exposures during boom and vessel decontamination operations.
