Biomedical waste: Waste Categories, treatment options and color coding mnemonic

PLEASE NOTE: This post was written in 2015, the categories have been updated since then :(
I have not deleted this post because some still find it helpful :)
We will edit it soon!

Greetings, people.

This waste disposal system is used in India. Since it's all complex and plain memorization, why not make a mnemonic? :D

For those who don't know the categories and stuff in detail, I'll copy paste them at the end of the post for reference. I'll be sharing the mnemonic first.

Let's begin! ^__^

How to remember Waste Categories:

1-3: HAM (Human, Animal, Microbiology)
4-7: Sharp medico, bloody solid (Sharps, Medicines, Blood stained or Soiled, Solid)
8-10: LAC (Liquid, Ash, Chemicals)


How to remember colour coding of waste category:

Random mnemonic: Yellow has 6 letters. 1 x 2 x 3 = 6
So these categories go into the yellow bag.

Draw this table step by step. Write everything one below the other. You'll get it when we are done!

Step 1: Write the names of the colours in this order -
Yellow
Red
White
Black
Mnemonic: You Record Warner Bros.

Step 2: Write 1-5 in this sequence -
1 2
3
4
5

Step 3: Write 6 - 10 (excluding the Liquid-y stuff, that is, Category 8)
6
6 7
7
9 10

Step 4: Write treatment options
ID
AMC
AMC DS
DSL
(Remember the acronyms, somehow. Identity, Armed medical college, DSL internet? :/)

And you are done! :D

Colour Coding  - Waste Category - Treatment Options:

Yellow - 1,2,3,6 - Incineration / Deep burial
Red - 3,6,7 - Autoclaving / Micro waving / Chemical Treatment
Blue/ White translucent - 4,7 - Autoclaving / Micro waving / Chemical Treatment and Destruction / Shredding
Black - 5,9,10 (Solid) - Disposal in Secured Landfill

That's all!

All the best for your exams!

  6. Waste can get unsafe on the off chance that it isn't dealt with appropriately. It doesn't make a difference if it's harmed machines, papers, issue gear, Hamilton junk removal
