Hospital staff wear magnetized badges that allow them to open the keycard locks to restricted rooms, such as drug storage.
Old badges, ones that are discarded or sold on the black market, are demagnetized so they cannot be used by criminals.
- A stylized Caduceus (two snakes wrapped around a staff with wings) was seen around the hospital and on hospital equipment and uniforms. The design commonly associated with hospitals is the rod of Asclepius (a staff with just one snake), carried by Asclepius, the Greek god of medicine. The caduceus is the staff of Hermes and is most usually associated with commerce or trickery, but it began to be associated with medicine in the United States around the turn of the 20th century, due to confusion with the Rod of Asclepius. Its use in the Firefly 'verse reflects the influence of the former United States in Alliance culture.
- Use of the Rod versus the Caduceus varies in the United States. Professional organizations, such as the American Medical Association, use the Rod more often because they have a better understanding of the 2 symbols. Commercial organizations, such as hospitals, use the Caduceus more often because it is more visually memorable as a business logo/symbol.
