Oklahoma City firefighters and Oklahoma Highway Patrol troopers were investigating reports of hazardous material at the Oklahoma State Capitol on Tuesday afternoon. The Capitol was not being evacuated as the response unfolded, and officials said no one had been hurt.

The Oklahoma Highway Patrol and the Oklahoma City Fire Department are investigating after the possibly hazardous material was discovered at the State Capitol, according to News 9. The substance in question has since been located, and investigators are now working to determine exactly what it is.

Troopers told the station that no one has been adversely affected by the material so far. Despite the hazmat response, officials said the Capitol building itself was not being cleared out at the time of the report.

No Word Yet on What the Substance Is

As of Tuesday afternoon, the identity of the material remained unknown, with the investigation still underway, per the same News 9 account. Authorities have not released further detail on where exactly on the Capitol grounds the material was found or how it was discovered.

In December 2019, Oklahoma City Hazmat crews were called to a Department of Agriculture building just north of the Capitol, according to okcfox.com.

That earlier incident involved two employees working in a second-floor lab area who were exposed to a small amount of carbon disulfide, okcfox.com reported at the time. Emergency personnel evacuated the two workers from the building, with the response attributed to then-OKC Fire Chief Benny Fulderson.

Tuesday's situation at the Capitol remains under investigation, and it is not yet clear what the substance is or how the case will be resolved. Hoodline will update this story as more information becomes available.
