What are Dangerous Goods Placards?

The Canadian TDG / IMDG non-worded placard is a dangerous goods safety mark that is displayed on a large means of containment (MOC). It is used to identify dangerous goods and to show the nature of the danger they pose. In certain situations, the UN number for specific products inside the transportation container must also be shown on or beside the placard. The markings listed below all measure 10.75” x 10.75”. More information on placards and labels can be found on the Government of Canada website.
