INTRODUCTION Alaska had the highest work-related fatality rate of any state during 1980-1989. The National Institute for Occupational Safety and Health established the Alaska Field Station (AFS) to address this problem. METHODS AFS established surveillance systems to provide scientific assessments of occupational hazards. Interventions were developed in collaboration with partners and evaluated. RESULTS During 2000-2009, Alaska experienced a 42.5% decline in work-related fatalities over the previous decade of 1990-1999. In 2009, the workplace fatality rate for Alaska was 5.6/100,000 workers. Commercial pilot deaths were reduced by 50% and Bering Sea crab fishing death rates were reduced by 60%. Building on this success, AFS established national programs to improve safety in the commercial fishing and oil and gas extraction industries. IMPACT ON INDUSTRY A focused, epidemiological approach to reducing fatalities in high-risk occupations is effective. Ongoing commitment to this type of approach will assist in continued success in Alaska and elsewhere.

BACKGROUND During the 1990s, Alaskan pilots had one of the most hazardous occupations in the US. In 2000, a multifaceted public health initiative was launched, focusing on Alaskan air taxi/commuter (AT) operations, including risk factor identification, improved weather information, and the formation of an industry-led safety organization. METHODS Effectiveness was assessed by comparing rates of crashes using Poisson regression, comparing trends in annual numbers of crashes, and assessing changes in the number and type of controlled flight into terrain (CFIT) events. RESULTS The greatest improvements were seen in Alaska fatal AT crashes with a 57% decrease in rates between time periods. While the number of AT crashes in the rest of the US steadily declined during 1990-2009, Alaska only showed significant declines after 2000. CFIT crashes declined but remained more deadly than other crashes. CONCLUSIONS This coordinated effort was successful in reducing crashes in the Alaskan AT industry.

BACKGROUND Occupational fatality rates among oil and gas extraction industry and specifically among drilling contractor workers are high compared to the U.S. all-industry average. There is scant literature focused on non-fatal injuries among drilling contractors, some of which have introduced engineering controls to improve rig efficiency and reduce injury risk. METHODS We compared injury rates on new and old technology rigs operated by the largest U.S. drilling contractor during 2003-2012, stratifying by job type and grouping outcomes by injury severity and body part affected. RESULTS Six hundred seventy-one injuries were recorded over 77.4 million person-hours. The rate on new rigs was 66% of that on old rigs. Roughnecks had lower injury rates on new rigs, largely through reduced limb injury rates. New rigs had lower rates in each non-fatal injury severity category. CONCLUSIONS For this company, new technology rigs appear to provide a safer environment for roughnecks. Future studies could include data from additional companies.

During 2003-2013, fatality rates for oil and gas extraction workers decreased for all causes of death except those associated with fall events, which increased 2% annually during 2003-2013 (1). To better understand risk factors for these events, CDC examined fatal fall events in the oil and gas extraction industry during 2005-2014 using data from case investigations conducted by the Occupational Safety and Health Administration (OSHA). Sixty-three fatal falls were identified, accounting for 15% of all fatal events. Among fatal falls, 33 (52%) workers fell from a height of >30 feet (9 meters), and 22 (35%) fell from the derrick board, the elevated work platform located in the derrick (structure used to support machinery on a drilling rig). Fall fatalities occurred most frequently when drilling rigs were being assembled or disassembled at the well site (rigging up or rigging down) (14; 22%) or when workers were removing or inserting drill pipe into the wellbore (14; 22%). Measures that target derrickmen and workers engaged in assembling and disassembling drilling rigs (rigging up and down) could reduce falls in this industry. Companies should annually update their fall protection plans and ensure effective fall prevention programs are in place for workers at highest risk for falls, including providing trainings on proper use, fit, and inspection of personal protective equipment.
