Quarries Honored with Sentinels of Safety Awards

The U.S. Department of Labor's Mine Safety and Health Administration (MSHA) named the winners of the 2010 Sentinels of Safety Awards. The Sentinels of Safety Awards recognize mining operations in various categories that record the most hours in a calendar year without a single lost-time injury.

Beginning in 2005, a minimum of 4,000 hours were required for consideration, and the award categories were expanded to allow greater recognition of the safety accomplishments of both small and large mines.
