Six Die of Suffocation Inside Septic Tank in Odisha’s Kalahandi

A tragic incident in Odisha’s Kalahandi district has claimed the lives of six people after they reportedly suffocated inside a septic tank while removing centring materials. The incident took place at Gaudkarlakhunta village under Madanpur Rampur police limits and has left the entire area in deep shock.

Workers Collapsed One After Another

According to reports, the mishap occurred while workers were removing the centring structure from a newly constructed septic tank. Initially, one mason entered the tank and reportedly collapsed after inhaling toxic gases. In an attempt to rescue him, five others entered the tank one after another and also lost consciousness.

All six died due to suffocation inside the tank. Another worker was critically injured and shifted from Madanpur Rampur hospital to the district headquarters hospital for advanced treatment.

The deceased have been identified as Nimain Pal (48), his son Akash Pal (28), labourer Adal Majhi (55), Manoranjan Hati (27), Chhanda Jal and Bipul Jal.

Toxic Gases Suspected Behind Deaths

Officials suspect that poisonous gases inside the septic tank caused the deaths. Experts say septic tanks and sewer lines often contain dangerous gases such as Hydrogen Sulfide, Methane and Ammonia, which can lead to unconsciousness and death within minutes if proper safety measures are not taken.

Labourers entering such confined spaces without protective equipment remain highly vulnerable to such accidents.

CM Announces Compensation

Chief Minister Mohan Majhi expressed grief over the incident and conveyed condolences to the bereaved families. He also announced financial assistance of ₹4 lakh each from the Chief Minister’s Relief Fund (CMRF) for the next of kin of the deceased.

What is Centring?

Centring is a temporary support structure used during construction work to hold wet concrete in place while roofs, beams or slabs are being built. It is usually removed after the concrete becomes strong enough, generally after 14 to 21 days depending on weather conditions and construction size.
