Man Burned During Hash Oil Explosion in Homeless Encampment

A man suffered burns during a hash oil explosion in a homeless encampment in San Francisco’s Potrero Hill neighborhood on Sunday morning, police said.

The explosion occurred around 10:30 a.m. Sunday at the encampment located beneath a highway overpass near the intersection of San Bruno Avenue and Alameda Street, according to police.

Based on the initial police investigation, it appears that a man in his 40s was attempting to cook hash oil in the encampment when a fire ignited and an explosion occurred.

The man suffered burns to his chest and hands. He was transported to a hospital and treated for injuries not considered life-threatening.

Hash oil explosions have been reported in cities around the Bay Area recently, including one in Walnut Creek on Oct. 31 that severely injured two people and left a multi-unit apartment building uninhabitable.

Fire officials say butane is used to prepare hash oil and that there are minimal restrictions on the sale of the flammable gas.
