A "CSU technician/foreman" is not a standard job title; the role likely combines the hands-on duties of a technician with the supervisory responsibilities of a foreman in a specific technical field, such as crime scene investigation (CSU), construction, or central sterile processing. A CSU (Crime Scene Unit) technician/foreman would oversee crime scene investigations and manage staff, while a construction foreman handles site operations and crew management, and a sterile processing foreman manages the equipment and procedures for sterilizing instruments.
