The correct way to seal a clinical waste bag is by using clinical waste ties, which are designed for secure sealing. These ties often come with sequential serial numbers to provide traceability and a comprehensive audit trail.
It is recommended that the swan neck method of closure is used to securely seal each bag of clinical waste. The bag should be filled no more than two-thirds full, allowing the neck of the bag to be twisted around, and then looped around itself into a 'swan neck' shape. A bag seal or tie can then be passed over the twisted neck of the bag, then tightened to create an effective seal.
