LOCATION : This is essential piece of information for anyone trying to find a particular piece of apparatus, etc. We mentioned that cupboards, drawers, etc. should be numbered and labelled with their contents. The location specified for each piece of apparatus should be unique.

A plan of the lab showing the sitting of numbered cupboards together with a list of the contents of each numbered site pinned on the notice-board or stuck on a wall in the preparation room will provide a useful reference.

Location of people is also important. To this end, you need to know who is using and in which lab during the day and where each member of the department would normally expect to be working. You should know and, if necessary, have evidence to show where the people are working at any time in science department. To facilitate this, you need to know who has borrowed what and where he is using it.
