What is the proper transport procedure for potentially infectious material when there are no packing supplies provided for the sample to go to another laboratory?

When no packing supplies are available for transporting potentially infectious material, use a sturdy, leak-proof container that can securely hold the sample, such as a plastic bag or a sealed container. Clearly label the container with appropriate biohazard symbols and necessary documentation, including the sample's origin and contents. Ensure the container is placed inside a secondary outer layer, such as another bag or box, to provide additional protection. Always follow local regulations and guidelines for transporting hazardous materials.
