In a narrow London Street there's some building work afoot involving scaffolding...."Take Care! Scaffolders at work"
This is a splendidly simple and catch all cautionary sign. It's says what's going on..."scaffolders at work" and gives some all encompassing advice "Take Care!". Sure there's an encouraging explanation mark, but no need for shouting capitals. Lower case being easier to read of course, as well as more polite.
It's not trying to pre-empt any specific risk, rather a general warning, encouraging some personal ownership and simple common sense.
