It's common to hear in some workplaces that following certain safety rules and procedures is a nuisance. So this workplace safety poster aims at reminding workers that doing them helps keep them safe, even if they think some just make their job unnecessarily complicated. They are in place because people have been seriously injured or killed. So they aren't optional in the workplace, and that everyone is required to follow them.
 
This is one of two posters with the same content, just different designs.
