Just follow section 11.16 of ICH Q7 guidelines.
Some additional tips are
Classify the laboratory reagents as liquids and solids.
Classify further as flammable, non-flammable, toxic, volatile, acidic, basic.
Classify the volumetric solutions as light-sensitive, light-resistant container compatibility broadly.
List out all the laboratory reagents as per the classification make a separate list for all these.
Read "How to Handle
Laboratory Reagents and Standard Solutions" for a detailed explanation. Let me know if you need anything else.
Cheers.
By the way, I have just joined the forum and right away I am having a healthy discussion. Looking forward to it.
