Butane hash oil (BHO) extraction: Difference between revisions

Line 7:

A "well-ventilated area" is commonly used to describe the area that is ideal for butane extraction. A "well-ventilated area" is not a room with the window open, it is not a kitchen stove top fan turned on, it is not a garage with the door open to let some air in - these areas do have ventilation, but the movement of air is unpredictable and may lead to explosions if butane does build up in the room. To be well ventilated, an area must have a constant and steady supply of fresh air flowing through the area. This is achievable indoors in a fume hood (commonly seen in chemistry labs) and is de facto achievable outdoors. '''Preforming a B.H.O. extract in a "well-ventilated area" does not eliminate the flammability and explosion hazard associated with the process, it only lowers this risk.'''

While butane is a flammable gas, in order for an explosive event to occur there needs to be an ignition source or spark. This spark can come from common sense items such as a lighter or pilot light on a stove, but sparks can also occur in less obvious ways. Electric sparks can be created simply by wearing clothes - the common "shock" one experiences after shuffling around with socks on and touching a metal object is sufficient to cause an explosive event if the concentration of butane is at 1.86% of atmospheric levels.

Both a spark and a sufficient quantity of butane are necessary for an explosion to occur - if either one of these is lacking, by pure chance, an explosive event will not occur. Just because there have been experiences of producing B.H.O. indoors without explosive events does not mean it is a safe practice; this element of chance can render a dangerous operation intert.
