"Hallett Materials is one of eight mining operations to receive the
2002 Sentinels of Safety Award. Think about this. You are one of the
eight out of 14,000 mines in the U.S...."


I trust this fully answers your question.  

However, please do not rate this answer until you have everything you
need.  If there's anything more I can do for you, just post a Request
for Clarification to let me know.

Cheers,
