Six people died of suspected toxic gas suffocation after falling into an under-construction septic tank in Gaud Karlakhunta village, Madanpur Rampur police station area of Kalahandi district, Odisha, on Tuesday, 27 May 2025. A seventh worker remains critically injured. The incident is among the deadliest confined-space accidents reported in the state this year.

How the tragedy unfolded

According to local police sources, Nimain Charan Pal, the homeowner, accidentally fell into the septic tank at around 8 am while inspecting ongoing construction work. When he did not emerge after a prolonged period, his son Akash Pal climbed in to rescue him — and became trapped as well.

Four other workers at the site — Adal Majhi, Manoranjan Hati, Baikuntha Jal, and Chhand Jal — then entered the tank in quick succession in an attempt to pull the father and son to safety. All six succumbed, with the suspected presence of toxic gas inside the enclosed structure identified as the likely cause of death.

Victims and medical response

All six victims were rushed to the nearest Community Health Centre (CHC), where doctors declared them dead on arrival. A seventh worker, Pankaj Bhoi of Hatikhoj village, sustained critical injuries and was subsequently transferred to the District Headquarters Hospital (DHH) at Bhawanipatna for advanced treatment.

The deceased have been identified as Nimain Charan Pal, his son Akash Pal, Adal Majhi, Manoranjan Hati, Baikuntha Jal, and Chhand Jal — all from Gaud Karlakhunta and nearby villages.

Government response and ex gratia

Odisha Chief Minister Mohan Charan Majhi expressed deep grief over the deaths and announced an ex gratia of ₹4 lakh each for the next of kin of every deceased person from the Chief Minister's Relief Fund (CMRF). The announcement was made through the Chief Minister's Office on its official social media handle.

'On learning about the tragic accident at a construction site in Madanpur Rampur, Kalahandi district, which claimed the lives of six people, Chief Minister Mohan Charan Majhi has expressed deep grief and expressed his condolences to the families of the deceased,' the CMO stated.

The broader safety concern

Confined-space fatalities at construction and sanitation sites are a recurring hazard across India. Workers frequently enter septic tanks, sewers, and manholes without adequate safety equipment or gas-detection tools, often triggering chain-rescue attempts that multiply casualties. This incident follows a pattern seen in similar tragedies in other states, where the absence of basic confined-space protocols turns a single accident into a mass casualty event. Authorities have yet to confirm whether any safety checks were in place at the Kalahandi site.

Further investigation by local police is underway; the condition of the critically injured Pankaj Bhoi is being monitored at DHH Bhawanipatna.
