Having worked in a public library for 12 years now, I've punched my card at the timeclock, filled out forms in triplicate with carbon paper, and seen quite a few emergency eyewash stations in staff kitchen areas.

I found these posters at a flea market in New York years ago and they've sat in a drawer waiting to be framed and hung in my woodshop.  No, I don't have a woodshop over here.  Yet. 

As always, enjoy the images and feel free to copy them and reuse them.
