WINSTON-SALEM, N.C. — Two members of the cleaning staff at Wake Forest Biotech received minor injuries after coming into contact with a chemical substance Thursday morning in Winston-Salem.

Officials said the workers came into contact with ‘Trizol Reagent’ after less than 1/2-gallon of the chemical was spilled while the two were cleaning the Biotech center at 575 N. Patterson Ave. around 1 a.m. 

The substance caused skin burns and irritations, but the workers have since been treated and released, officials said. 

A Hazmat team along with police and fire departments were called to the scene.  Hazmat teams are personnel specially trained to handle dangerous substances.

The area was blocked off for about four hours while crews tended to the workers and cleared the scene.

Trizol has the potential to cause seizures, but that was not the case in this situation, officials said. 

Wake Forest Health spokeswoman Karen Richardson said Trizol is used to extract genetic material from cells. 

Richardson said the spill, which was contained to a small area, is being investigated by the health system’s Environmental, Health and Safety Department. 

“The public was not in danger,” Richardson said.
