A cook fills a spray bottle with degreaser from a bulk drum. What must be done before it goes on the shelf?

解析

Any working container a chemical is transferred into must be labeled with the common name of that chemical, so no one on any shift mistakes it for something else. A date and initials identify who filled the bottle but not what is in it, and relying on the crew's memory fails the moment a new or borrowed employee picks it up. Transferring a chemical into a food container is separately prohibited, because it invites exactly the mix-up the label rule exists to prevent.
