Final answer:
An EMT should dispose of a used disposable bag-valve-mask device according to hospital or EMS service policy, typically in a biohazard container, and ensure it is sterilized as per protocol.
Step-by-step explanation:
To help limit cross-contamination and accidental pathogen transmission, an EMT should dispose of a used disposable bag-valve-mask (BVM) device according to hospital or EMS service policy. Proper disposal often involves placing the used device in a designated biohazard container. In accordance with health and safety protocols, the contaminated device should never be washed for reuse or simply wrapped up for later use if it's not visibly soiled, as this does not guarantee the removal of pathogens. Instead, the BVM must be handled as biohazardous waste and sterilized, if that is the policy of the service, before being disposed of or included in the waste stream.
Personnel must always practice proper hygiene, wearing protective equipment during patient care and handling any medical equipment. Contaminated waste is typically incinerated or autoclaved in a strong basic solution, which effectively sterilizes the materials and ensures the safe disposal of potentially hazardous items.
