The Canadian Standards Association
Technical Committee on Signs and Symbols for the Occupational
Environment has drafted CSA Standard Z321 in order to warn, inform,
and communicate messages in this environment.
The system consists of three classifications, each divided into subtitles in combination with six colors and four shapes.
Size relationship of the shapes was determined with consideration

an order for obligatory action.

 Caution:
