It should be noted that performing this extraction indoors significantly increases the risk of fires, explosions, and physical harm. Outside of a fully functioning fume hood, the production of BHO indoors carries with it a great inherent risk for explosions and bodily harm. '''While one may personally know of successful experiences of producing B.H.O. indoors, this should not be taken as evidence of this safety, given the large elements of chance involved.''' | It should be noted that performing this extraction indoors significantly increases the risk of fires, explosions, and physical harm.

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, along with the sparks created by the compressors in most common kitchen freezers, is sufficient to cause an explosive event. | While butane is a flammable gas, in order for an explosive event to occur there needs to be an ignition source or spark.

The flammability of a gas depends on its concentration in the atmosphere. The butane concentration must fall between an upper and lower limit to be able to ignite. The lower limit of butane concentration in the atmosphere is 1.89% and the higher limit is 8.5%<ref> Flammability of Gasses http://people.clarkson.edu/~wwilcox/Design/flamlim2.pdf</ref>. If the concentration of butane falls in this range and there is a spark present, there '''will''' be an ignition and an explosive event. | The flammability of a gas depends on its concentration in the atmosphere.

* '''Protective gloves and mask''' - This is needed to protect against the frozen tube and butane vapors, both of which can cause bodily harm - '''Wearing the proper safety equipment is imperative for properly performing a B.H.O. extraction'''. | * '''Protective gloves and mask''' - This is needed to protect against the frozen tube and butane vapors, both of which can cause bodily harm - '''Wearing the proper safety equipment is imperative for properly performing a B.H.O. extraction'''. | ||
* '''Heat source''' - Avoid any open flame heat sources and heat sources that can cause flammable sparks as '''butane is unpredictable, highly flammable and explosive!''' An induction hot plate is a viable heat source option, as is any non-sparking, flame proof electrical heater or a simple water bath. If using a hot water bath, make sure to monitor the temperature and set it up over an induction heat source that does not have a pilot light. | * '''Heat source''' - Avoid any open flame heat sources and heat sources that can cause flammable sparks as '''butane is unpredictable, highly flammable and explosive!'''

Always have a fire extinguisher or fire blanket on hand in case of fire. It is important to check the operability of the fire extinguisher by examining it or refilling it at least once a year to ensure that it will work during an explosive event. | ||
