Final answer:
UN marking is used on non-bulk shipping containers to indicate approval for hazmat shipping, as part of the GHS system followed internationally.
Explanation:
The marking that is stenciled or indicated on non-bulk shipping containers to certify that the container is an approved package for shipping hazardous materials (hazmat) is the UN marking. This symbol indicates that the packaging complies with standards set by the United Nations for the safe transportation of hazardous materials. It is part of a globally recognized system known as the Globally Harmonized System of Classification and Labelling of Chemicals (GHS), which also includes other elements like hazard pictograms, precautionary statements, and signal words.
The UN number provides information related to the specific chemical or substance inside the container and ensures its correct identification during transportation. Other related information, such as Hazard Communication Standard (HCS) labels, may also be present on the packaging. HCS labels provide a quick assessment of the chemical's hazards and include items such as the name, address, and phone number of the responsible party, chemical identification, and precautionary statements.
