On day 1 of the Rat job, blow up the lab.
Select any Rats job in either Crime.net or Crime.net Offline. At the start of the mission, you will make your way down the path toward the house. You will need to find at least two ingredients in order for this to work. You can find ingredients inside the back of truck; they are located either in the locked shed, in the basement, or in the washroom inside the house on the first floor.
Once you have the ingredients, head upstairs inside the house where you will have to cook some methamphetamine. You will get instructions on where to put the chemicals; ignore the instruction and purposely put the wrong ingredient in first which will cause the lab to explode and light the room on fire. Exit as soon as you start the fire so you do not get downed from the explosion and flames. The achievement will unlock straight away.
