Step 1: Safety First & Disclaimer
There is some safety precautions that you have to take when refilling your disposable propane cylinders and you will need to handle it properly and observe all the best-practice safety protocols.
#1 Always do the refill process outside.
#2 Never smoke during the entire process.
#3 Be sure there is no open flame in the area.
#4 Wear safety glasses and protection gloves for added safety.
Again, I am not responsible for any accident that can happen when you refill your own disposable propane tank.

You will also need a standard propane tank at least 50% full, empty disposable cylinder, a kitchen scale an a notepad to keep track of the weight of your cylinders. For added safety I also recommend safety glasses and gloves (not show on the picture)
