1. Develop a 5-Whys Tree and determine the Root Cause and JSHA
2. Complete a Risk Analysis and indicate the risk on the FTA
3. Sketch an FTA based on the Fishbone Diagram
4. Develop an Ishikawa Diagram to determine potential causes for the accident

6. Ryan Provancher Oil Field Worker, North Dakota A broken pipe, a cloud of hydrogen sulfide and a death from toxic exposure Ryan Provancher, just 25 years old, had already worked in the booming oil fields of North Dakota for seven years when he reported to his job as a roustabout foreman for Driven Services on October 9th. He and a co-worker, Eric Williams, were replacing pipes at an oil pumping location near Kildeer in Dunn County, North Dakota. One of the pipes burst, releasing a cloud of hydrogen sulfide, a highly toxic colorless gas which carries a distinctive rotten egg odor.24 High concentrations of the gas, according to an OSHA fact sheet, can cause shock, convulsions, inability to breathe, extremely rapid unconsciousness, coma and death. Effects can occur within a few breaths, and possibly a single breath.25 Williams, who himself was hit with a heavy dose of the gas, ran from the building, but returned when he saw that Provancher was still inside and dragged him out of the building. Williams attempted CPR on his co-worker until an ambulance arrived. Provancher was taken by ambulance to St. Josephs Hospital in Dickinson, North Dakota. He died two days later, on October 11th. The incident is under investigation by OSHA, although the agency was unable to send an investigator to the scene until nearly a week after it took place. A government shutdown was in effect at the time, and a federal worker had to be called back from furlough to carry out an inspection.26 24 Man in oilfield accident exposed to hazardous gas, Bismarck Tribune, Oct. 16, 2013 25 OSHA Fact Sheet: Hydrogen Sulfide, U.S. Occupational Safety and Health Administration, 2005 26 Man exposed to hydrogen sulfide in fatal oilfield accident OSHA representative didnt visit site for nearly a week, Dickinson Press, Oct. 17, 2013 Ryan Provancher: At age 25, he was already a 7-year veteran of the North Dakota oil fields. 26 | P a g e Oil and gas extraction has become the most dangerous industry in America, according to 2012 data from the U.S Bureau of Labor Statistics. Deaths in the industry jumped by 23 percent in 2012, to 138 deaths from 112 in 2011.27 The 2012 figure is the highest number of deaths recorded in oil and gas extraction since BLS began the current Census of Fatal Occupational Injuries in 2003. The figure is based on preliminary data and is likely to become higher when final figures are released. The oil and gas extraction industry now has a fatality rate of 24.2 deaths for every 100,000 full-time workers higher than any other industry. The overall rate of fatalities in the United States is 3.2 deaths per 100,000 workers. Provancher, who is survived by his parents, grandparents, two brothers, two sisters and a girlfriend, was cremated in Dickinson on October 15, 2012.
