>> two extractors against that wall with plenty of working space, right? >> absolutely. >> you could have two more here. we want to process other people's stuff. so the money savings comes right away. >> come on in. we'll show you the extraction facility. >> how dangerous is this process? >> not nearly as dangerous as it used to be. >> we're being challenged with hash oil production. they force butane through the cannabis, and it extracts the oil. you can get a spark from the compressor, from the refrigerator or from the light switch and it will cause an explosion. >> from the research i've done, there is definitely a need for some regulations around setting up a room like this and there aren't any. absolute worst case scenario, you have a leak you don't detect right away, the room fills up with gas and -- this corner of the building explodes, literally. literally.
