A predawn explosion tore through a marijuana grow facility inside the Morrow-Gill Business Complex in Sand Springs, Oklahoma, early Thursday, killing one person, critically injuring another, and damaging multiple neighboring businesses. The blast happened around 1 a.m. and scattered debris blocks away from the site.
According to News 9, Sand Springs police, Sand Springs firefighters, and the Public Service Company of Oklahoma all responded to the scene, along with Oklahoma Natural Gas crews. Surveillance video reportedly captured a bright flash followed by a large boom at the moment of the explosion. The critically injured person was taken to a hospital, and the cause of the blast remains under investigation.
The complex where the explosion occurred sits on a five-acre property that once housed Morrow-Gill Lumber Co. for six decades before the lumber yard closed in 2015. The site was redeveloped and reopened in September 2019 as a commercial park with two single-story buildings totaling nearly 50,000 square feet of mixed industrial and office space, divided into 25 multi-tenant units, according to local reporting from Sandite Pride News. That layout helps explain why a single explosion inside one unit could damage so many surrounding businesses at once.
Multiple Businesses Affected, Access Restricted
Sand Springs Fire Chief Jeremy Wade said multiple businesses have been affected by the explosion, per News 9. Wade said he plans to establish an information area for business owners so they can learn about the situation and when they might be able to safely return. He said officials must first ensure everything is safe before allowing anyone back into the affected buildings.
Firefighters reported that nearby chemical facilities did not report issues following the explosion, and they said gas leaks of concern were not identified in the aftermath, per the same News 9 report. The story remains developing, with the specific materials that triggered the blast still unconfirmed.
State Scrutiny Over Grow-Facility Safety
The explosion lands amid intensifying statewide scrutiny of Oklahoma's commercial cannabis industry. Oklahoma Medical Marijuana Authority administrative rules updated through July 2026 require all commercial grow and processing facilities to hold an active Certificate of Occupancy issued by the Oklahoma State Fire Marshal or another authorized local authority verifying compliance with building and fire codes, according to the Oklahoma Medical Marijuana Authority. Separately, Oklahoma Statute Title 63 Section 427.12 bars chemical extraction processes using volatile solvents such as butane, propane, or carbon dioxide in spaces that are not authorized or certified, citing the high risk of catastrophic fire and explosion, per Oklahoma Statutes.
Whether the Sand Springs facility held a valid Certificate of Occupancy, and whether any extraction process was underway at the time of the blast, are open questions that investigators have not yet answered. Sand Springs has seen cannabis enforcement before: in July 2025, the Oklahoma Bureau of Narcotics and Sand Springs Police Department raided a grow operation on East Charles Page Boulevard, seizing more than 7,500 marijuana plants and 570 pounds of processed cannabis, according to the Keystone Gusher.
Part of a Broader Statewide Crackdown
The Oklahoma Attorney General's Office reported in May 2026 that aggressive state enforcement had reduced the number of licensed medical marijuana grow operations statewide from over 9,000 to fewer than 1,200. Oklahoma House Bill 2095 extended the state's moratorium on new commercial grow licenses through 2026, giving law enforcement and safety officials time to inspect active operations and shut down illegal sites, per the State of Oklahoma.
During his February 2026 State of the State address, Governor Kevin Stitt urged sending the state's medical marijuana system back to voters, citing persistent public safety concerns and regulatory challenges facing grow operations statewide, according to News On 6. The Sand Springs blast also follows a similar case Hoodline covered earlier this year, in which explosions rocked an Okfuskee County pot farm that state drug agents later determined was operating without a valid fire-code Certificate of Occupancy.
Fire safety experts are also working on new national standards for the industry. The National Fire Protection Association is developing NFPA 420, a standalone fire safety standard for cannabis growing and processing facilities, addressing risks posed by high-wattage lighting, dense wiring, and chemical extraction equipment, according to Fire Protection Engineering. Grow-facility fires have injured workers in Oklahoma before; an April 2023 fire at an Oklahoma City marijuana grow facility severely injured two workers, according to prior reporting from NBC News.
For now, the cause of Thursday's explosion in Sand Springs remains under investigation, and officials have not released the identities of the person killed or the person critically injured. Business owners in the Morrow-Gill complex are expected to receive updates from Chief Wade's office on the situation and when they can safely return to their properties.
