SAFETY AND HEALTH
Protecting the health and safety of our workforce has long been a core value at U. S. Steel, rooted in a legacy that dates back more than a century. Today, safety is embedded at every level of the organization, with leadership, supervisors, and frontline employees all accountable for striving to create and sustain a zero-harm workplace. Responsibility for one another’s safety is deeply ingrained in our culture and guides daily decision-making across our operations.
SAFETY FIRST IN ACTION: CONTINUOUS IMPROVEMENTS ACROSS OUR OPERATIONS
A central element of our unrelenting commitment to Safety First is continuous improvement in every corner of the business and in every aspect of operations. Our focus on Hazard Identification and Risk Assessment (HIRA) plays a key role in doing so, and our regular cadence of safety campaigns provide an excellent opportunity to share and learn how our facilities are making their operations even safer. In 2025, inspiring changes were made to prioritize safety, including
SAFETY COMMITMENTS AND PROGRAMS
Risk Reduction Safety Campaign
In 2025, our Mon Valley Works facility implemented the Risk Reduction Safety Campaign which included the installation of object proximity cameras to detect human figures located in “danger” zones, including in the larry car path and near moving forklift trucks. The camera monitors automatically give a warning signal if a human figure is seen approaching an established “danger” zone. Should the figure fully enter the “danger” zone, the monitor will sound an alarm and flash red, alerting more staff. Mon Valley Works plans to continue to implement various safety initiatives through this campaign over the coming years.
Cat® Driver Safety System
U. S. Steel implemented the Cat® Driver Safety System (DSS) across 58 haul trucks at its Minnesota Ore Operations in 2024 to address operator fatigue and distraction — key contributors to mobile equipment incidents. The system uses infrared cameras to detect microsleeps and distraction in real time, triggering in-cab alarms and seat vibrations to alert drivers. Verified events are reviewed and prompt supervisory intervention is performed if needed. Since deployment, verified distraction events have fallen by over 74% and fatigue events have dropped by 60%, resulting in improved operator safety and reducing equipment damage. The system also enabled the early detection of health conditions like sleep apnea. Privacy concerns were addressed through open communication and system transparency, emphasizing safety over surveillance.
U. S. Steel was selected as a 2025 National Safety Council Green Cross for Safety Award® finalist for the DSS.
