These are two Dangerous Goods shipping boxes, used in the shipment of biohazardous materials. Known as UN/4G/Class 6.2 boxes, they will contain cylinders, like the ones displayed in PHIL 14460, 14539, 15479, and 15480. In addition, note the directional arrows, indicating the box top. The label lying on the tabletop is a typical biohazard shipping label that must be placed on the outside of the box prior to shipping, and displays the universal symbol for Biohazardous Material. In writing, it states that the contents includes an Infectious Substance, as well as a directive stating, “In Case of Damage or Leakage Immediately Notify Public Health Authority”, and provides a phone number to the Dir. of the Center for Disease Control, Atlanta, Georgia. Also note the number 6 on the label, which represents the classification of the contents, or Class 6: Toxic and Infectious Substances, hence the use of this Class 6.2 box.
