A process safety incident is an unplanned event arising from the manufacturing process that results in a product release, fire, explosion, injury or community event. By managing, tracking and reporting process safety incident data, ACC member companies can benchmark their performance, demonstrate their commitment to transparency and set goals for improvement.
ACC members use the American Petroleum Institute (API) Recommended Practice 754 methodology for reporting annual process safety incident information. Under this methodology, Tier 1 process safety incidents, defined as any unplanned or uncontrolled release of any material, are given a severity score ranging from 0 to 135, 0 being the lowest-severity incident and 135 being the maximum severity score.
In 2022, 84 percent of the Tier 1 process safety incidents reported by ACC members were categorized as "low severity," meaning that they received a severity score from 0 to 3.
ACC member companies demonstrate their commitment to safe operations by implementing the Process Safety Code, which includes a company commitment to set process safety expectations, define accountability for process safety performance and allocate appropriate resources to achieve performance expectations.
