I've been asked before about the numbers in the diamond next to the doorway. This numbers signify the type of chemicals found in the building so firefighters know how to approach and address any fires.
In 1988 firefighters were dispatched to two trailers on fire at a construction site. They were told to approach with caution for fear of explosives. The two trailers contained 50,000 lbs of ammonium nitrate that caused a disastrous explosion, All 6 firefighters died. It was later determined the fires were set by arson.
