URS and its subcontractor employees have reached a milestone of 14.9 million safe hours of work at Hanford and other Department of Energy sites.
About 10,000 workers at nine projects, including three Hanford projects, worked the consecutive hours without a lost-time work injury or illness, according to URS.
At the Hanford vitrification plant, 3.5 million safe hours or 2,538 days without a lost-time injury was reached.
At the Hanford tank farms, Washington River Protection Solutions reached almost 3 million safe hours or 290 days.
Never miss a local story.
In addition Washington Closure Hanford reached almost 6.5 million safe hours, a record for Department of Energy decommissioning and demolition projects before a truck accident that sent the driver to the hospital in late January and ended the streak at 774 days.
URS plans to mark the accomplishment with donations to the American Red Cross.
"Safety is not only a fundamental business value, it is a commitment we make to our employees and one that our employees make to our customers," said David Pethick, general manager of URS Global Management and Operations Services Group, in a statement.
