When a person is employed by a company, they are normally issued some sort of equipment or tools that they are supposed to use in a regular course of their work. If they decide to quit the job or they are laid off they will have to return the tools or equipment in proper and working condition. The tools will be inspected, their number and condition, and in case anything is missing or broken that person will have to bear the cost of replacing that tool or instrument.
But what word or phrase could I use to say that someone who is quitting his job is required to account for the condition of a larger, immovable piece of machinery that he worked on.
Clearly I can't say that he was "issued with the machine" or that he "returned the machine", but he's still responsible that the machine is in proper and working condition. For example, there must not be missing parts, or defects due to his negligence or anything like that, for which he could be held responsible, and would need to pay for.
How can I say that he was "put in charge of the machine" when he started working for the company and also that, on quitting the job, and inspection of the machine he is "relieved of the responsibility for it".
