(Section 5.1) Major equipment (e.g., reactors, storage containers) and permanently installed
processing lines used during the production of an intermediate or API should be appropriately
identified. In addition, Section 5.2 indicates “Equipment should be identified as to its contents and
its cleanliness status by appropriate means”. Major equipment should have a unique equipment
number on it, for example, your reactors may be numbered R40, R41. In your batch record or on
your control panel in the control room, if you have a distributed control system as referred to, an
Operator should be able to see what’s happening with R40 and what is in it at any particular
moment.
