transportation." The figure below shows how to triple package (primary receptacle, <br />watertight secondary packaging, and durable outer packaging) according to the <br />regulations. <br />a. Primary Package <br />The primary receptacle contains the infectious substance and must be watertight to <br />prevent leakage. These can be made of glass, metal, or plastic and should include <br />screw-top tubes, flame-sealed glass ampoules, or rubber-stopped glass vials fitted <br />with metal seals. Screw caps should be fastened with tape for extra safety. <br />b. Secondary Package <br />One or more primary receptacles are placed in a water-tight secondary package. <br />Absorbent material, sufficient to absorb the entire contents of the primary <br />container(s ), must be placed between the primary and secondary package. The <br />secondary package should be labeled with name, address, and telephone number of <br />the shipper. <br />c. Outside Package <br />The secondary package is placed into the outer packaging, which must be of <br />sufficient strength to contain and protect the contents within. Outer packages must be <br />UN-certified, signified by having a UN specification mark on the outside of the <br />package. Shipping regulations require that an itemized list of contents be placed <br />between the secondary package and outer package. <br />Below is an example of packing for shipping of samples to the Washington State Public <br />Health Laboratory. <br />Packing and Labeling of Infectious Substances <br />Environmental Samples <br />Collection of environmental samples of concern is normally done by HAZMA T teams as <br />part of their response to a contaminated scene. HAZMAT teams should follow their <br />normal procedures for sampling and packaging of the materials. <br />33
