what is UN3373 and How to handle it ?

UN3373 is a code used to classify and label biological substances for transport. Specifically, UN3373 refers to “Biological Substance, Category B.” This classification is part of the United Nations Recommendations on the Transport of Dangerous Goods (often referred to as the UN Model Regulations).

UN3373 is used to identify and regulate the transport of biological materials that may pose a low or moderate risk to people and the environment if not handled properly. These biological materials can include clinical samples, diagnostic specimens, and other items containing biological agents that are not otherwise classified as infectious substances. Examples of items that might fall under UN3373 include blood samples, urine samples, and tissue specimens.

Here are some key points related to UN3373:

1. Packaging Requirements: When shipping materials classified as UN3373, they must be packaged in a manner that prevents leakage, breakage, and contamination during transport. This typically involves using leak-proof, durable containers and secondary packaging.
2. Labeling: Packages containing UN3373 materials should be labeled with the UN3373 code, the proper shipping name (“Biological Substance, Category B”), and a contact telephone number for emergencies.
3. Documentation: Shippers of UN3373 materials must complete shipping documents, including a waybill and a written statement indicating that the materials are classified as UN3373 and are properly packaged.
4. Training: Personnel responsible for handling and shipping UN3373 materials should receive training on the regulations and requirements for their safe transport.
5. Transport Mode: UN3373 materials can be transported by road, air, sea, and rail, so the regulations apply to various modes of transportation.
6. International Standards: The UN3373 classification is part of an international system for the transport of dangerous goods. It helps ensure consistency and safety in the handling and transport of biological materials across borders.

It’s important to note that UN3373 classification is specifically for materials that are not infectious substances. Infectious substances fall under a different classification (UN2814 or UN2900), and they have more stringent packaging and handling requirements due to their potential to cause disease.

Shippers and transporters of UN3373 materials should be familiar with the specific regulations and requirements for packaging, labeling, and documentation to ensure the safe and compliant transport of biological substances. Violating these regulations can lead to potential health and safety risks and legal consequences.
