Safety
Promoting Health and Safety
Our number one priority is the safety of our employees, contractors, business partners, customers and communities. To reinforce a strong culture of safety and high performance, we use a combination of management systems, operational standards based on industry best practices, and documented work processes and programs.


Life Critical Expectations
Our greatest focus is protecting the well-being of our people. Our goal is an incident-free, injury-free workplace where everyone who comes to our sites returns home safely at the end of the workday. We are committed to creating a safe work environment and preventing incidents and injuries across our operations.
We continuously strengthen our safety management systems and compliance programs by engaging employees and contractors through training, behavior-based safety programs, contractor safety councils, and sharing best practices and lessons learned.
Our Life Critical Expectations document outlines the safety requirements and behaviors expected of all employees and contractors to help ensure work is performed safely.
OSHA Voluntary Protection Program (VPP)
The Occupational Safety and Health Administration’s (OSHA) Voluntary Protection Program (VPP) recognizes private industry employers, workers and federal agencies that have implemented effective safety and health management systems. Companies and facilities that achieve VPP status maintain injury rates significantly lower than the Bureau of Labor Statistics averages for their respective industries.
VPP represents a cooperative effort between regulators and industry to drive higher level safety performance across organizations. Achieving VPP status requires completion of a rigorous application and onsite evaluation process conducted by OSHA, which can take multiple years.
The program includes three levels of designation: Demonstration, Merit, and Star status, the highest level. Each level reflects a commitment to maintaining and continuously improving workplace safety and health performance.
Working closely with regulators such as OSHA helps foster a safer workplace and strengthens safety culture. Today, we have earned 41 VPP Star certifications covering 54 MPC and MPLX facilities.


Personal Safety Performance
Consistent with our Core Values, we approach our work with an unwavering commitment to safety. To reinforce these values and drive strong performance, we use a combination of operational standards based on industry best practices, documented work processes, proven management systems, and behavior-based programs designed to train, protect, and empower our employees and contractors.
Employees and contractors have both the authority and responsibility to stop work if they believe a task is being performed unsafely. Work does not resume until the safety concern has been addressed, regardless of the size or scope of the job.
Process Safety
In simple terms, process safety helps ensure our pipes, tanks, processing units, valves and other equipment perform as intended to keep hazardous materials safely contained. We proactively manage our process safety risks by continuously strengthening management systems and programs such as mechanical integrity, management of change, safe work practices, and operating procedures. We also maintain a rigorous process safety risk assessment process to identify risks and implement the appropriate safeguards including alarms, automated shutoff systems, and relief devices.
We track and report process safety performance to demonstrate accountability to employees and stakeholders. Additional information on our performance and progress is available in the performance data table within our annual Sustainability Report.


Emergency Preparedness
Our commitment to preparedness helps ensure we can respond effectively should an emergency event occur. Through ongoing investment in response capabilities, we are equipped to mitigate and manage impacts to people, the environment and our operations. Each operating location maintains dedicated emergency response teams and site-specific preparedness and response plans tailored to local risks. These plans are regularly tested through drills and exercises to validate their effectiveness and execution
MPC’s Emergency Preparedness Group (EPG) oversees the company’s emergency response program, including companywide guidelines and procedures for preparing for and responding to emergencies. The group’s focus is to continually strengthen incident response capabilities by coordinating across the organization and sharing best practices and resources.

For emergencies requiring resources beyond those available at a local facility, the EPG maintains a Corporate Emergency Response Team (CERT). Team members are trained in the Incident Command System (ICS) and provide specialized expertise and support should an emergency occur.
