INTERSTATE NATURAL GAS ASSOCIATION OF AMERICA SAFETY SURVEY

As part of ONEOK’s ongoing commitment to pursue a zero-incident culture, the company participated in the Interstate Natural Gas Association of America (INGAA) Safety Culture Survey in 2014.

While the survey was organized by INGAA, of which our natural gas pipelines (NGP) segment is a member, we chose to take this opportunity to survey our entire operations group to see how we compare with other INGAA member companies and also to learn more about our own safety culture from the perspective of our operations employees.

The survey was designed to gain insight into our industry’s safety culture by surveying employee attitudes and opinions at our company and 17 of our peer companies.

More than 1,200 of our employees participated in the survey – a more than 90 percent participation rate. Because the NGP segment is an INGAA member, only answers from NPG employees were included in the INGAA industrywide results.

Survey Results

In the NGP segment, 301 employees participated in the survey. The segment had an overall safety index score of 74 percent, which compared favorably with the combined total INGAA industry average safety index score of 73 percent. Survey participation among natural gas pipelines operations employees was 94 percent, compared with the INGAA average response rate of 79 percent.

Survey results show the partnership’s total safety index scores compare favorably with the INGAA industry averages. The information compared the more complex and widely varying types of ONEOK Partners’ operations (natural gas, natural gas liquids, refined products, natural gas gathering, processing, treating, storage and fractionation) with the INGAA interstate natural gas pipeline average scores.

We received scores of more than 90 percent positive in multiple categories, including:

»» Teaching safety procedures to new crew members;

»» My co-workers help each other; and

»» Equipment needed to do a job safely is provided.
