Three people have been taken to hospital due to a chemical explosion at the University of Sydney.
It is reported that a chemical reaction occurred at around 10 am today while a staff member was carrying a bucket of acid.
The staff member was reportedly using an umbrella to protect the chemical before the reported explosion.
Two contractors standing nearby inhaled the fumes, while the staff member suffered chemical burns to their arms.
All three people were taken to The Royal Prince Alfred Hospital for treatment.
Fire and Rescue NSW sent hazardous response vehicles to the scene to decontaminate the street.
