UN3373 Standard Key Requirements


The packaging must be of good quality and strong enough to withstand the shocks and loadings normally encountered during transport. It must prevent any loss of contents that could occur due to vibration or changes in temperature, humidity or pressure. The P650 packaging instructions for liquid substances state:-

a) The primary receptacle(s) shall be leak proof;

b) The secondary packaging shall be leak proof;

c) If multiple fragile primary receptacles are placed in a single secondary packaging, they shall be either individually wrapped or separated to prevent contact between them;

d) Absorbent material shall be placed between the primary receptacles(s) and the secondary packaging. The absorbent material shall be in quantity sufficient to absorb the entire contents of the primary receptacle(s) so that any release of the liquid substance will not compromise the integrity of the cushioning material or of the outer packaging;

e) The primary receptacle or the secondary packaging shall be capable of withstanding, without leakage, an internal pressure of 95 kPa (0.95 bar).

To date laboratory personnel have had to fashion various packaging solutions to meet the UN3373 requirements to transport patient samples. These include wrapping the primary container in an absorbent material, placing this in a sealed plastic bag and then putting all this into a rigid box. This requires multiple materials and can result in mailing packages being of considerable size, increasing the cost of postage.
