The transport of infectious substances and patient samples, whether national or international, must comply with the UN Model Regulations. In order to comply with the regulations, it is essential to classify infectious substances for transport and to ensure their safe packaging.

In the logistics of samples and infectious substances, collaboration between the parties – shipper, transporter and recipient – is necessary for the safe and expeditious transport of such materials.

General preparation of consignments of infectious substances for transport

Because the hazards presented by Category A infectious substances (UN 2814 and UN 2900) and Category B infectious substances (UN 3373) are different, the packaging, labelling and documentation requirements for the two categories are different.

The packing/packaging requirements are determined by the UNCETDG and are set out in Packing Instruction P620 (PI602 for ICAO/IATA regulations) and Packing Instruction P650.

At Tecnisample we offer a wide range of outer packaging, secondary packaging, absorbent materials, complements and accessories for the logistics of biological samples depending on the infectious substance to be transported.

Triple packaging of infectious substances

The basic triple packaging system, to be used for all infectious substances, comprises 3 types of packaging in the following three layers:

  1. Primary container or packaging. An impermeable and leak-proof container containing the sample, this container should be wrapped in absorbent material sufficient to absorb all the fluid in case of breakage.
    • Examples of primary container: vial, test tube, PETRI plate, etc.

2. Secondary packaging. A watertight, impermeable and durable second packaging that encloses and protects the primary container(s). Multiple vessels may be fitted, provided that sufficient absorbent material is used to absorb all of the fluid in the event of a rupture. They must withstand pressures in excess of 95kPa (kilopascals) over a range of -40ºC to 55ºC.
Examples of secondary packaging: jar, flask or bag.
3. Outer packaging. Secondary packagings are placed in outer shipping packagings that protect the contents from outside elements during transit with a suitable cushioning material. Normally, each package prepared for shipment must be marked and labelled and accompanied by the relevant shipping documents. Outer packagings may be made of different materials, must be larger than 10 x 10 cm on their sides and must withstand a drop test from 1.2 metres.
