Final answer:
Personal belongings of the technician should not be contained in a laboratory servicing clipboard, which should instead hold necessary tools, documentation, and emergency supplies.
Step-by-step explanation:
The item that should not be contained in each servicing clipboard during laboratory work is C) Personal belongings of the technician. The clipboard needs to hold tools and equipment, necessary paperwork and documentation, and emergency supplies, to ensure a smooth and safe working environment in the lab. These might include items such as microscopes, Bunsen burners, inoculating loops, and safety documentation like the location of fire extinguishers and eyewash stations.
It is also crucial that the clipboard has a record of any issues with equipment, as well as checks for correct labeling of specimens, if any are being handled. Personal belongings do not contribute to the function or safety protocols of the laboratory and can indeed pose a contamination risk, therefore they should be kept separate from the work area.
