Two metro marijuana businesses catch fire in one week

Oklahoma City, Okla. (KOKH) — In the past seven days, there have been two incidents at medical marijuana businesses in The Oklahoma City metro area.

A flash explosion at a medical marijuana processing business in Jones was strong enough to bring down its wall and injure three people.

According to its website, Elite Extractions, LLC uses CO2 to extract oils from Marijuana.

Firefighters told Fox 25's crew they had a hard time getting inside.

To get certified with the Oklahoma Medical Marijuana Authority, any business has to be inspected by their local government.

The Oklahoma City Fire Department handles inspections in the city.

They say some of the processes can be dangerous if not done the right way.

“Anytime you’re mixing hazardous material for any type of process, you’re talking about a dangerous situation," said Battalion Chief Prince Morgan, who is in charge of fire code compliance. "That’s why you have to have established guidelines."

Morgan says in the short time medical marijuana has been legal, Oklahoma City hasn't had any major incidents.

“Across the country, yes there have been several that have happened," Morgan said. "We’ve been fortunate here in our jurisdiction not to have any catastrophes happen."

Each business has to be inspected yearly based on what exactly they're doing, making sure it has the right equipment to be up to code.

If that changes, they have to be inspected again to stay open legally.
