how to safely cut a oil drum in half to make an evaporator
Just heard from a friend that someone recently cut into a steel barrel and did not know what was in it and blew himself up.
I Have a decent heating oil tank that i would like to make into an evaporator. It has about 20-25 gallons of fuel oil in it , which i will take out. My question is how do you make sure it is safe to cut.i.e. not in explosive range, and what tool or method would you,or have you used . grinder,saws all, plasma cutter?
or is there a method of removing all the flammable material from the inside?
Thanks Rod
