A phlebotomy technician is preparing to send several specimens to an off-site reference laboratory. According to IATA and DOT regulations, which of the following is an essential component of proper packaging for biological substances, Category B?
- AA single primary receptacle within a cardboard box.
- BA biohazard label affixed directly to the primary receptacle.
- COnly the original collection tube placed directly into a shipping envelope.
- DA primary receptacle, a secondary watertight packaging, and a rigid outer packaging.
Show answer & explanationAnswer & explanation
Correct answer: D. A primary receptacle, a secondary watertight packaging, and a rigid outer packaging.
IATA (International Air Transport Association) and DOT (Department of Transportation) regulations for shipping biological substances, Category B (UN 3373), mandate a 'triple packaging' system. This system consists of a primary receptacle (the specimen tube), a secondary watertight packaging (e.g., a sealed plastic bag), and a rigid outer packaging (e.g., a sturdy box) with appropriate labeling.
Why the other options are wrong
- A. A single primary receptacle is not sufficient; it lacks secondary containment and proper outer packaging.
- B. While a biohazard label is required, it's affixed to the *outer packaging*, not directly to the primary receptacle, and this option only covers one aspect of packaging.
- C. This is entirely inadequate and unsafe for transporting biological specimens, violating all regulations.
Triple Packaging System
The 'triple packaging' system for biological substances (Category B) consists of a primary receptacle, a secondary watertight packaging, and a rigid outer packaging, designed to prevent leakage and protect specimens during transport.
- Mandated by IATA/DOT.
- Ensures containment and safety.
- Primary, secondary, and outer layers.
Memory trick: Triple Package: Protect, Contain, Ship Right.
