The Louis Griesemer Sterling Safety Award was created in 1994 to recognize the companies that have the lowest total accident incidence rate for the previous year in their category among NSSGA members. Sterling Safety Awards recognize member companies that achieve the lowest injury incidence rate for the previous calendar year in their size category. The award was renamed in 2019 to honor the commitment to safety shown through the career of Louis Griesemer. Safety data for the Sterling Awards is provided by MSHA.
