A PBT who works as a substitute at different facilities arrives for a new assignment. The station where he is assigned to work has a standard phlebotomy chair, a bariatric chair, a stool for the PBT, and a well-stocked supply cabinet between the chairs. There are biohazardous waste & standard trash cans close to the door. Across the room there is a counter with a sink, a centrifuge and other processing equipment, and a sharps container. What should be changed?
