Firefighters responded to a hazardous materials call in St George’s early evening on Wednesday.

Two vehicles and six firefighters responded to the call at a facility on the Southside property.

According to Fire and Rescue Service spokesperson Delton White, the call was made to address what was thought to be toxic smoke and fumes released by approximately one gallon of an unknown substance.

“The five staff members on site when the incident occurred immediately evacuated the building,” Mr White said.

On arrival, firefighters donned protective suits which allowed them to enter the building.

“After the substance was contained, they then re-entered the building to carry out ventilation of the premises to ensure it would be safe for staff to enter,” Mr White said.

Information on the substance was not provided.
