In a sterile procedure why does the health care worker have to label tape with date, time (in military time), and initials?

To let others know that the procedure was completed. This keep things in order and provides safety to the patient

answer; im thinking (france);

nope, but i have cleaned my brush in my cup of not as potentially harmful but nevertheless, very upsetting for scottish/british folks. especially if you've used the last teabag for it

explanation:

there could be something in that . . i am indeed an old scottish man!

there's a bit of bolshie-ness with it too though. i won't let go of the old ways . . tea and whisky . . whether the young whippersnappers like it or not!
