Let Op (Attention)

Found this sign pretty funny in the context of a 23 floor skyscraper and a mega crane in the background. I was thinking what would my last words /thoughts be if something like that was to happen to me on the either of the two structures :)
It's probably some weird reaction to the griep innoculation shots all workers at the hospital had to receive today.

Take care, fellow blippers. Remember life is unpredictable so don't lose a chance to make the most if it.
