I often see microscopes inside the office rooms of professors as well as other teaching members. They may not use them on daily basis but once in a while, or sometimes heavily used by a few of them. Some of them examine hospital slides received by that department from patients sputa to look for hazardous organisms (e.g. TB bacilli).
My question, according to the quality assurance standards of teaching laboratories, and from the safety point of view, is it acceptable to use microscopes inside offices instead of laboratory rooms? Is it acceptable to use them inside the office while wearing the casual clothes instead of the lab coat, and without gloves?
