FOG NIOSH/NORA Fatalities in Oil and Gas Database Detailed information fatalities in the U.S. Includes: all fatal events to U.S. land-based and offshore oil and gas extraction workers, irrespective of NAICS codes. Excludes: midstream, downstream, non-fatal injuries Data Sources: OSHA, crash reports, media, etc. Limitations: off-site motor vehicle events

25. Exposure to very high concentrations of VOCs in hydrocarbon products may occur when hatches are opened PBZ measurements identified benzene as a potential VOC exposure hazard None of the 35 PBZ samples exceeded OSHA benzene PEL Some samples exceeded NIOSH REL and STEL for benzene Flammable/explosive hazards can exist Additional field research is needed to more fully characterize risk for exposure Initial Flowback Conclusions

27. Summary Fatality Rates are improving, but work left to do. New hazards are emerging: inhalation of hydrocarbons. Old hazards persist.
