Developing: Hazmat incident at Crystal Clean in Cayce

CAYCE, S.C. (WOLO) – The City of Cayce Fire Department and other agencies are currently managing an active hazardous materials situation at Crystal Clean, 627 Poplar Street this morning.

According to investigators, potassium hydroxide and sodium hydroxide were accidentally mixed with cooking oil, which caused chemical off-gassing and a tanker became warm to the touch.

Several homes in the immediate area have or are being evacuated at this time. All residents within a ¼-mile radius are directed to evacuate as a precaution. City of Cayce police and fire will assist and direct with the evacuations.

Lexington School District Two says in an abundance of caution, Brookland-Cayce High School is on a temporary HOLD response protocol, meaning the school day is continuing on a normal schedule, but students and staff are remaining inside the building.

Officials ask you to please avoid the areas of Poplar Street until further notice.

Authorities say they will notify the public as soon as it is safe to return to the area.
