Study Notes

Safety Marks

Must comply with TDGR, 49CFR, or UN recommendations regarding color, symbols, and label durability.
Labels required on small containers must be resistant to weather, and fading cannot significantly alter the original color.
Mandatory information on safety marks includes shipping name, hazard class, identification number, and packing group.
Labels must be clearly visible, placed squarely on the package without obstructions.
Small liquid containers may feature an orientation label, but it is not mandated by roadway regulations.
Dangerous goods in small containers demand labeling, with some exemptions for limited quantities and permits for equivalent safety levels.
Class 3 flammable liquids must display their flashpoint on small packages transported by ship.
Some classes may necessitate subsidiary class labels, while marine pollutant labels could also be required.

Placarding Requirements

Large means of containment must have UN numbers displayed when required, such as during an ERAP or for liquids/gases in direct contact.
Placards must be affixed to all four sides of the container.
Intermediate bulk containers (IBCs) with a capacity of 450L to 3,000L can display two placards with the UN number.

Responsibilities for Safety Marks

The person in charge of containment determines the need for changing or removing safety marks.
Marks must be removed or covered by individuals who neutralize, unload, or clean contents once danger is no longer present.
Display of DANGER placards is optional, and they can be used instead of other placards until the hazardous goods are removed.

UN Packaging Performance Standards

Packaging types categorized by material and performance level (e.g., steel drums, aluminum barrels, wood jerricans).
Categories include standard, removable head, non-removable head, and various other containers.
The Packing Group classifies materials by their degree of danger, adhering to international and local regulations for transport.

Storage of Dangerous Goods

The August 2020 Beirut explosion, caused by improperly stored ammonium nitrate, resulted in 218 deaths and $15 billion in damages, highlighting the importance of safety.
Industry groups are focusing on guidance for the safe storage and handling of dangerous goods in warehouses, especially following recent incidents.

Storage Practices

Use approved containers and observe venting requirements for flammable and corrosive materials.
Avoid storing incompatible materials together, such as acids with bases or flammables with oxidizers.
Do not arrange chemicals alphabetically unless grouped by compatibility, and never store them in domestic fridges/freezers.

Loading and Handling

Proper loading and securing of dangerous goods is crucial to prevent accidents during transport.
The safety of loads must be assessed to ensure they are secure and comply with regulations.

Accidental Release and Reporting

A Dangerous Occurrence is defined as the release of dangerous goods that exceeds set quantities, endangering life, health, property, or the environment.
In case of a spill, follow the TACC protocol: Think safety, Act quickly, Contain the spill area, and Clean up.
Requirements for emergency reports associated with releases or anticipated releases include notifying local authorities, with specific reporting thresholds based on class and packing group categories.
