Safety

Safety both on and off the job is a priority at Marathon Petroleum Corporation (MPC). MPC is committed to creating a safe environment and works diligently to achieve an accident-free, incident-free workplace throughout all its operations. Our focus is on continually improving on-the-job safety and process safety through training, awareness, and performance improvement and compliance programs.

We have developed a “Life Critical Expectations” document that outlines the company’s expectations for its employees and contractors to work safely.

Health and safety are important to our success as a company; if our employees and contractors are not safe, then other measures of success lose their meaning. We track the metrics reported in this section as a matter of accountability to our employees, contractors and to the communities in which we live. We want you to know how we’re doing.

Figure 1: Safety Performance (Injury Rates)

_{Injury Rates represents the number of incidents per 200,000 hours of work. The Days Away Rate represents injuries that caused at least one missed day of work, also per 200,000 hours of work.}

MPC also measures safety performance applying the MPC Safety Performance Index (MSPI). This metric is an internally developed metric based on recordable injuries, weighted for their severity.

In simplest terms, process safety means that our pipes, tanks, processing units, valves and other hardware all work as intended – keeping hazardous substances where they belong. Of course, for that to work, the controls we have in place must all function properly too – maintenance plans, equipment testing, alarms, monitoring systems and the procedures people use as they work with these components. We track the metrics reported in this section as a matter of accountability to our employees, contractors and to the communities in which we live. We want you to know how we’re doing.
