A chemical explosion at the University of Sydney has resulted in the hospitalisation of three people after acid-based chemicals being moved for disposal reacted and caused a vapour cloud.



The incident occurred on Tuesday, 15 October 2024, near the university’s Sports and Aquatic Centre in Darlington.

According to Fire and Rescue NSW (FRNSW), a staff member was transporting chemicals when a reaction occurred, leading to an explosion. The worker, along with two nearby contractors, was exposed to the vapour cloud and taken to Royal Prince Alfred Hospital for treatment.

Emergency Response and Hospitalisation

Emergency services, including paramedics and specialist HAZMAT teams, were called to the scene shortly before 10am after reports of a person suffering chemical burns. FRNSW firefighters immediately set up an exclusion zone and called for HAZMAT assistance to secure and decontaminate the area.

One individual sustained burns to their hands, while the two other individuals were hospitalised as a precaution due to possible inhalation of fumes. All three people were transported to the Royal Prince Alfred Hospital, located in Sydney’s inner west, and are reported to have suffered minor injuries.

Safety Precautions and Ongoing Investigations

NSW Fire and Rescue has confirmed that the chemicals were being moved for disposal when the reaction occurred. While the exact nature of the chemicals remains unclear, it has been confirmed that the explosion produced a vapour cloud. According to one report, the employee transporting the chemicals had been using an umbrella to shield the substances at the time of the reaction.

Both SafeWork and the NSW Environment Protection Authority (EPA) have been notified of the incident and are expected to review the matter. The university has advised that anyone in the area who may have been exposed to the chemicals should seek medical advice immediately if experiencing symptoms such as skin or eye irritation or respiratory discomfort.

Community Advisory

The University of Sydney issued a statement advising members of its community, especially those present near the Sydney Uni Sports and Aquatic Centre and Services Building on the morning of the incident, to monitor for any symptoms of exposure. The university has expressed relief that no serious injuries were reported but continues to encourage caution and medical consultation for anyone concerned.



The area was successfully decontaminated following analysis by specialist teams, and it has since been deemed safe.
