Technician's File : Technician file is for you to keep any information that might be of use to you or your successor in the future. The form that it takes is a matter of personal preference. You could use any of the systems we have mentioned.
The file may include the following information:
1. Names and address: suppliers, sources of information, useful contacts, etc.
2. Recipes: for all the solutions, stains etc. that you have to prepare.
3. Sources of specific items and materials, e.g. fertile hens' eggs, hearts, insects, mouse, various chemicals, various instruments, glassware etc.
Technician's file must include asset's register, which include all the received chemicals, equipment, glassware etc. from time to time. In case of audit, you will be able to locate any particular item and place it for audit. This register or stock book should be passed to your successor in future.
No doubt you can think of many more things as file entries - especially if you are new to the job! In this case, there must be several things that you wish you could ask someone about. The technician's file would solve this problem.
