Incident Rate Information

At Williams, safety is the most important aspect of our operations.

We’re dedicated to leveraging best practices and institutional knowledge across all Williams’ assets to ensure we set the standard for operational excellence including safety, reliability, and integrity. Our objective is to identify and diminish any potential risk and to ensure compliance with federal and state regulations.

We make safety a part of our life—every day, everywhere. We’re not only concerned with employees and their families’ safety—we want everyone on or near our job sites to be safe, including our contractors.

Williams has a set of safety performance metrics that are routinely generated and reviewed, we also recognize it is very important to benchmark our safety performance against our industry peers. As such, we have standardized our internal metrics to be displayed against an industry benchmark set by the GPA Midstream Association (GPA).

To ensure a balanced and deliberate focus on all aspects of safety, Williams has also developed process safety metrics in 2017, which are standard and routinely generated safety performance reports available to all employees. These process safety metrics include:

  • Process safety incidents
  • Safety system activations
  • Accidental ignitions
  • Loss of primary containment

In addition, we routinely report our safety performance metrics to our employees and board of directors.

The information below compares year-end 2015, year-end 2016 and year-end 2017 in two key areas of employee safety.



Williams operates nearly 33,000 miles of pipelines throughout the United States. Of those pipelines, 56% (18,000+ miles) are regulated by the Pipeline and Hazardous Materials Safety Administration (PHMSA).

Safe operations of our pipelines is paramount to our success as a prudent operator and we strive to operate safely in everything we do, every day. Williams reportable incident rate is less than half of the comparable industry average seen in 2016.
