LOS ANGELES (AP) — Police and fire investigators launched a criminal probe Sunday into the cause of an
explosion at a hash oil manufacturer in downtown Los Angeles that sent firefighters running for their
lives.
Detectives from the Los Angeles Police Department’s major crimes division were working with the city Fire
Department’s arson investigators to determine what might have sparked the blast that shot a ball of
flames out of the building Saturday night and scorched a fire truck across the street, police spokesman
Josh Rubenstein said.
"We’re in the very early stages of the investigation … to understand what happened and figure out
how to move forward," he said.
The federal Bureau of Alcohol, Tobacco, Firearms and Explosives was assisting local fire investigators,
an agency spokeswoman said.
The blast injured a dozen firefighters. Some of them who ran out onto sidewalks, where they tore off
their burning protective equipment, including melted helmets, officials said.
"Everybody off the roof!" a firefighter shouted in scanner traffic captured on
Broadcastify.com.
"Mayday mayday mayday! All companies out of the building. Mayday mayday mayday!" another
shouted.
Firefighters first thought they were battling a routine structure fire, city fire Capt. Erik Scott told
KNX Radio, but as they got a little farther in the building they started to hear "a loud hissing
sound and a significant rumbling that you could feel vibrating throughout the area."
He said "one significant explosion" shook the neighborhood around 6:30 p.m. Firefighters inside
had to run through a wall of flames he estimated as 30 feet (9 meters) high and wide, and those on the
roof scrambled down a ladder that was engulfed in flames.
Three firefighters were released after spending the night in the hospital, fire department spokesman
Nicholas Prange said Sunday. Of the eight who remained hospitalized, two were in critical but stable
condition, he said. Officials initially announced that 11 firefighters were injured. But Prange said a
12th was treated and released for a minor injury.
All were expected to survive.
"Things could have been so much worse," said Los Angeles Fire Department Medical Director Dr.
Marc Eckstein, who helped treat the injured at Los Angeles County-University of Southern California
Medical Center.
There was light to moderate smoke when firefighters entered the one-story building in the city’s Toy
District and went on the roof — normal procedures to try to quickly knock down any flames.
Los Angeles Fire Chief Ralph Terrazas said one of the firefighters inside the building thought things
didn’t seem right — the pressure from the smoke and heat coming from the rear of the building were
increasing. He directed everyone to get out, and they quickly started exiting the building as it was
rocked by the explosion.
Firefighters on the roof scrambled down ladders with their protective coats on fire. The wall of flames
shot out the building and burned seats inside a fire truck across the street.
More than 200 firefighters rushed to the scene, and dozens of engines, trucks and rescue vehicles clogged
the streets. The fire spread to several nearby buildings, but firefighters were able to douse it in
about an hour.
Scott said the building was a warehouse for SmokeTokes, which he described as a supplier for makers of
"butane honey oil." Butane is an odorless gas that easily ignites, and it’s used in the
process to extract the high-inducing chemical THC from cannabis to create a highly potent concentrate
also known as hash oil. The oil is used in vape pens, edibles, waxes and other products.
A call to SmokeTokes went unanswered on Sunday, and the company’s voicemail was full.
On its website, SmokeTokes advertises a variety of products including "puff bars," pipes,
"dab" tools, vaporizers, "torches and butane," and cartridges. The company says it
is "an international distributor and wholesaler of smoking and vaping products, and related
accessories."
Prange, the LAFD spokesman, said carbon dioxide and butane canisters were found inside the building but
that it was still not clear what caused the blast.
Adam Spiker, executive director of the cannabis industry group Southern California Coalition, said he
didn’t know what activities were taking place inside the building. However, if the business was using
butane in cannabis extraction it would be illegal because the city has never issued a license for that
type of operation.
Because of safety concerns, such businesses are typically restricted to industrial areas and kept away
from urban centers.
"If they were doing volatile extraction with butane … they couldn’t be legal in the city of LA to
do those types of activities," Spiker said.
He said the coalition was unaware of the business having any type of license and "something about
this doesn’t pass the smell test."
Information so far "puts up a lot of alarm bells," Spiker said.
In 2016, there was another major fire at a business called Smoke Tokes at a nearby address. The Los
Angeles Times reported at the time that it took more than 160 firefighters to put out the blaze and that
they encountered pressurized gas cylinders that exploded in the fire.
No one was injured in the fire. It was unclear whether that business and the one that burned Saturday
were connected.
