Most BHO explosions occur in west coast states, Colorado and Michigan.  But they’ve also been discovered in New York, Rhode Island, Virginia, Illinois and elsewhere.

Colorado

In April 2014, four BHO explosions occurred in Colorado within one week.  In one case, responders rescued an infant and four-year-old after a father made BHO in a townhouse kitchen.
