Chlorine gas leak in Pune's Kondhwa hospitalises 17, fire teams respond
Synopsis
A chlorine gas cylinder left behind at an abandoned water purification unit in Pune's Kondhwa turned a quiet Wednesday night into a medical emergency — 17 hospitalised, including emergency responders. Coming just weeks after the Boisar oleum gas disaster, it raises an urgent question: who is auditing Maharashtra's defunct industrial sites?
Key Takeaways
A chlorine gas leak from an abandoned water purification unit near Gangadham Chowk, Kondhwa, Pune triggered panic on the intervening night of Wednesday–Thursday, 30 April 2025 .
At least 17 people were hospitalised with breathing difficulties; officials warn the number could increase.

A chlorine gas leak at an abandoned water purification unit near Gangadham Chowk in Kondhwa, Pune, triggered widespread panic on the intervening night of Wednesday and Thursday, 30 April 2025, sending at least 17 people to hospital with breathing difficulties. Authorities confirmed the situation has since been brought under control, though officials cautioned the number of those affected could rise.
How the Leak Unfolded
Preliminary findings indicate the leak originated from a cylinder containing chlorine gas that had reportedly been left behind at a defunct water purification facility in the Kondhwa area of Maharashtra's Pune. The hazardous release from the storage tank spread rapidly through the surrounding neighbourhood, prompting immediate evacuation of residents from the affected zones.
The precise circumstances under which a hazardous chemical cylinder came to be stored at an abandoned unit remain under investigation, raising serious questions about safety compliance and regulatory oversight at defunct industrial facilities.
Emergency Response
Personnel from the Fire Department responded swiftly, deploying a total of four fire tenders, including a specialised vehicle equipped with Breathing Apparatus (BA) sets, to contain the leak. 14 affected individuals were shifted to Sassoon General Hospital and other nearby medical centres using '108' government ambulance services.
The emergency response was not without casualties of its own — one fire officer and a firefighter suffered adverse health effects from exposure and have been admitted to hospital for treatment. Officials have reassured residents that all those affected are currently out of danger.
Investigation and Safety Concerns
Authorities have initiated a formal investigation to determine how hazardous material came to be stored at a non-operational facility. The incident has reignited concerns about the adequacy of safety inspections at abandoned chemical and industrial units across Maharashtra's urban belt.
Notably, this is not an isolated incident in the region. On 2 March 2025, a massive leak of oleum gas (fuming sulfuric acid) at a chemical unit in the Boisar MIDC area of Palghar forced the evacuation of over 2,600 people, including 1,600 students. The National Human Rights Commission (NHRC) took cognisance of that incident, citing potential human rights violations — underscoring the systemic nature of industrial safety lapses across the state.
Current Status
Officials confirmed that the chlorine leak has been fully contained and the area has been declared stable. Residents who were evacuated are being allowed to return as conditions normalise. The investigation into the Kondhwa incident is ongoing, with further details awaited from authorities.
With two major gas leak incidents in Maharashtra within two months, pressure is mounting on the state government to conduct urgent audits of abandoned industrial and chemical storage sites across the region.
Point of View
Kondhwa in April — point to a systemic failure in monitoring abandoned industrial and chemical sites, not a string of bad luck. The fact that a chlorine cylinder was sitting in a defunct water purification unit, apparently undetected, exposes gaping holes in the state's safety inspection regime. The NHRC's intervention after Boisar should have been a wake-up call; instead, Kondhwa has arrived. Without mandatory, time-bound audits of non-operational facilities and enforceable penalties for non-compliance, Maharashtra's urban and peri-urban populations will remain at risk from hazards they cannot see coming.
