A chemical explosion erupted at AGChem, a chemical plant in Waltloo, Pretoria, on Thursday.
According to reports, big clouds of yellow smoke were coming from the plant, Rekord East reported.
Police spokesperson Captain Koba Brits said she received information that nitric acid was being mixed at the plant, and that the explosion was caused by the mixture.
The fire department managed to evacuate everyone at the plant.
Brits said neighbouring factories were also being evacuated, as the chemical smoke was highly poisonous.
