UN number 3105 identifies Organic peroxide type D, liquid, which is classified under Class 5.2.
Understanding UN Numbers
United Nations (UN) numbers are universal four-digit identification codes used in the international transportation of hazardous materials. These numbers provide a standardized system for identifying dangerous goods, ensuring that they are handled, stored, and transported safely across different regions and countries. Each UN number corresponds to a specific hazardous substance or a group of substances with similar hazardous properties.
Details of UN 3105
UN 3105 is specifically assigned to a particular type of organic peroxide, indicating its chemical nature and physical state for regulatory and safety purposes.
| UN Number | Class | Proper Shipping Name |
|---|---|---|
| UN 3105 | 5.2 | Organic peroxide type D, liquid |
What Does "Organic Peroxide Type D, Liquid" Signify?
- Organic Peroxide: These are thermally unstable substances that contain a bivalent -O-O- structure. They can undergo exothermic decomposition and are characterized by their potential for explosive decomposition, rapid burning, and sensitivity to impact or friction. They are distinct from other oxidizing substances.
- Type D: Organic peroxides are categorized into seven types, from A to G, based on their degree of hazard. Type A represents the most dangerous organic peroxide, while Type G is the least dangerous. "Type D" indicates a moderate hazard level, signifying that the substance is capable of undergoing a vigorous decomposition, but may not meet the criteria for more dangerous types like Type C or Type B.
- Liquid: This specifies the physical state of the substance at standard transportation temperatures. The physical state is crucial for determining appropriate packaging, containment, and handling procedures.
Importance in Hazardous Materials Transportation
The designation of UN 3105 for "Organic peroxide type D, liquid" is vital for ensuring safety and compliance in the transport of dangerous goods. This identification enables:
- Accurate Labeling and Placarding: Packages and transport units carrying UN 3105 must display specific hazard labels and placards (e.g., for Class 5.2) to alert handlers and emergency responders to the inherent dangers.
- Appropriate Packaging: Specific packaging requirements are mandated for UN 3105 to safely contain its liquid state and moderate hazard level, minimizing risks during transit.
- Emergency Response Planning: In the event of an incident (e.g., spill, fire), emergency services can immediately identify the substance as an "Organic peroxide type D, liquid" using its UN number, allowing them to implement suitable safety protocols and mitigation strategies.
- Regulatory Compliance: Shippers, carriers, and consignees must adhere to international regulations, such as those set by the United Nations Model Regulations on the Transport of Dangerous Goods, which govern the transportation of substances like UN 3105.
