Label Requirements – Demo

Topic Progress:

Small Means of Containment

Every small container and every package that contains dangerous goods must display a label. Some exemptions may apply, such as limited quantities and a permit for equivalent level of safety. The flashpoint or the flashpoint range for Class 3 Flammable Liquids must be displayed on small packages or containers transported by ship.

Some classes may require Subsidiary class labels with the class number on the bottom of the label as per column 3 of Schedule 1 of the Regulations. Marine pollutant labels may be required as per Column 10 of Schedule 1 of the Regulations.

Labels must be placed at a square on a point and must not be obscured by any part of the attachment to the package and/or container.
Small containers or packages containing liquids may also display an orientation label, which is not a requirement of the regulations by road.

Example of labeling for fully regulated shipment. As per illustration:

A = Ship “from” and “to” information
B = Proper Shipping Name
C = UN Number
D = Net Weight
E = Class 2.2 – Hazard Class Label

In addition to the label, all packages or containers must also include the proper shipping name and the technical name, if applicable in parenthesis, as well as the UN number. Due to the size of some containers or packages, tags for a label may be used and must contain the proper shipping name on the tag.

Toxic – Inhalation Hazard

When dangerous goods that are subject to special provision 23 are in transport in a small means of containment, the words “toxic by inhalation”, “toxic – inhalation hazard” must be displayed on the small means of containment next to the shipping name, unless these words are already part of the shipping name.

When dangerous goods that are subject to special provision 23 are in transport in a large means of containment, the words “toxic by inhalation”, “toxic – inhalation hazard” must be displayed on the large means of containment in addition to any placard required by this Part.

Dangerous goods safety marks must remain displayed on all small containers and packages until cleaning or purging the container has removed all contents. The person who cleans or purges the container must remove safety marks when no hazard condition exists
