THIS CACHE IS NOT AT THE POSTED COORDINATES
A common sight in chemistry classrooms around the nation (and on the sides of semi trailers) is the NFPA 704 diamond you see in the background. I don't know if it's been long since you've been in a classroom, but you better hope you're still familiar with the diamond.
PLEASE NOTE: The difficulty level is for the cache hide itself, not the puzzle.
