It's a simple term that encapsulates the fact that relationships at work can reasonably be non-intimate, inconsequential, unimportant and even, dare I say it, disposable or substitutable.

Non-disposable protective equipment must not be reused unless they have been properly disinfected.

ONLY disposable items, sterile and non-sterile will be used. At case end, all items used on the case, including instrumentation, will be disposed of in the gray incineration bins.
