Which of the following is a common process safety metric?

Incident rates are a common process safety metric as they provide quantifiable data on the frequency of accidents and near misses within an operational environment. Tracking incident rates is crucial for organizations to identify hazards, evaluate the effectiveness of safety management systems, and drive improvements in safety performance. This metric helps organizations assess trends over time and measure how changes in processes or practices influence overall safety. By focusing on incident rates, companies can implement targeted interventions to minimize risks and improve workplace safety.

In contrast, the other options focus on factors that are not directly related to process safety. Employee satisfaction scores, while important for workforce engagement and retention, do not provide specific insights into the safety performance of processes. Revenue growth and market share, valuable metrics in evaluating a company's financial health and competitive standing, are not indicators of safety performance or hazards present in the processes. Hence, incident rates stand out as the most relevant and actionable metric for assessing process safety.
