U. S. Steel committed to achieving the certification at all its facilities by 2024, as part of the health and safety goals outlined in the 2021 Sustainability Report.

“We are pleased to reach this safety and sustainability milestone more than a full year ahead of our 2024 target.

Steel Košice President. “We strive to maintain the highest safety performance standards, while always looking forward to ensure that we are prepared to address the next safety challenge.”

“This certification builds on our zero-harm culture, including developing an enhanced Safety Management System that empowers employees to assess, reduce and eliminate workplace risks with an improved safety communications systems and stronger contractor safety processes,” said Robert C. Rudge, Jr., Vice President and Chief Safety and Security Officer. “ISO 45001 certification gives management and our highly-skilled employees better data and structure to enable proactive, strategic safety practice improvements, as well as fuller awareness of high-risk and high-hazard activities that will build on our strong safety record.”
