Measuring Safety Improvements

The members of API envision a petroleum industry that conducts and manages its operations safely and with respect for the environment and the safety of its workers and the public. Because of this commitment, the collection of safety data in the form of benchmarking surveys reflects the industry's desire to provide a consistent, reliable and accurate industry metric for measuring and tracking safety trends and to promote its continuous improvement. Benchmarking surveys help companies understand how efficient they are over a host of issues and lead to improvements in their programs. Examples of safety surveys include: WIIS, OII, PSE

The Survey of Occupational Injuries, Illnesses and Fatalities in the Petroleum Industry (OII)

The OII is an annual survey that collects data on Petroleum Industry Occupational Injuries, Illnesses, and Fatalities, both within the United States and internationally, as well as for both employees and contract workers. Participants are asked to submit data according to the U.S. Bureau of Labor Statistics (BLS) guidelines. The “Survey of Occupational Injuries, Illnesses, and Fatalities in the Petroleum Industry: Report to Participants” is available only to participating companies and is available through the OII database website.

Participation is voluntary and the number of participating companies varies from year to year. Therefore, the reader should exercise caution when using this data to characterize the performance of the industry as a whole.

Prior year's survey is published in April of the current year.
