scientist is working in an aseptic processing suite to fill syringes with an insulin finished product (it will be an injectable). The only door into the suite is through the gowning room. The only door out of the suite is through the exit air lock, which leads to the de-gowning room. Draw or describe their work environment including what is the air differential pressure in their aseptic suite in relation to the surrounding spaces such as the gowning room? Why is this the differential pressure? What might be the air classification in their work area, the aseptic suite? Give three physical characteristics of that suite.
