What happened here
Three workers aged 21, 20 and 50 died after they became unconscious in a tank at a Sandhar company site in the Bhondsi police station area of Gurugram on Wednesday 11 November 2026. Colleagues pulled them out and they were taken to Ekta Hospital in Badshahpur and then to Park Hospital, where they died, according to most reports. Reports differ on whether they fell in or went in to clean the tank, and on whether it was a chemical tank or a safety tank. Police registered an FIR against the company management, citing sections 106 and 3(5) of the Bharatiya Nyaya Sanhita, on a complaint that the workers were made to enter without safety arrangements. No gas or cause has been confirmed.

What happened
Three workers died on Wednesday 11 November 2026 after they became unconscious inside a tank at a company called Sandhar on Jail Road, in the Bhondsi police station area of Gurugram, Haryana. The Gurugram tank deaths came to light on the afternoon of the day; The Tribune puts the time at around noon. The three men were aged 21, 20 and 50. Two were from Bihar and the third was a resident of Badshahpur in Gurugram. Reports say colleagues pulled them out and took them to Ekta Hospital in Badshahpur, which referred them to Park Hospital, where all three died during treatment. We found no report of anyone being injured and no report that a colleague went into the tank.
Police have registered a case against the company management at Bhondsi police station. Times Now Navbharat reports that the complaint says the workers were made to enter the tank without the necessary safety arrangements, and that the FIR cites sections 106 and 3(5) of the Bharatiya Nyaya Sanhita. These are police allegations, not findings of a court. Police say they are checking whether safety arrangements were in place and how the workers came to be in the tank. At the time of reading, on 12 November 2026, no arrest, no labour department action and no statement from the company had been reported in any page we opened.
The reports do not agree on what the tank was or how the men came to be in it. Most call it a chemical tank, and The Tribune, a Bhasha agency report and Jagmarg say the workers fell in. Amar Ujala and ETV Bharat say they went down to clean it, and ETV Bharat and a News18 video description call it a safety tank. Most reports speak of toxic gas or chemicals but none names the gas, and no official has said what killed the three. We set out these differences below and treat the cause as unknown.
What the reports say
- When: Wednesday 11 November 2026, around noon (The Tribune) or in the afternoon (all other reports)
- Where: A Sandhar company site on Jail Road, Bhondsi police station area, Gurugram, Haryana; UNI places it in Dhumaspur
- Who: Three company workers aged 21, 20 and 50; two from Bihar (Muzaffarpur and Nawada districts) and one from Badshahpur, Gurugram. No names are used here
- What: The three became unconscious in a tank said to hold chemicals and gas; most reports say they fell in, two say they had gone down to clean it
- Rescue and hospitals: Colleagues pulled them out; they were taken to Ekta Hospital, Badshahpur, then referred to Park Hospital, where they died during treatment (most reports)
- Dead and injured: Three dead; no injured reported
- Police action: Bhondsi police took the bodies for post-mortem at the Civil Hospital mortuary and registered a case against the company management; Times Now Navbharat cites BNS sections 106 and 3(5)
- Allegation: The complaint says workers were made to enter the tank without necessary safety arrangements (Times Now Navbharat; Janta Se Rishta); police are checking this
- Cause: Not established; no official has named a gas or a cause of death
- Arrests and company: None reported and no company statement found, as of 12 November 2026
Where reports differ and what we do not know
- Tank: Chemical tank (The Tribune, Bhasha, Jagmarg, Times Now Navbharat); a “safety tank” being cleaned (ETV Bharat, News18); one report says it held about a foot of water or chemical (Amar Ujala). The headline address of one News18 report says septic tank; we could not open that page
- How they were in the tank: Fell in (The Tribune, Bhasha, Jagmarg) or went down to clean it (Amar Ujala, ETV Bharat). Nobody has explained why they fell, if they did
- Gas: Reports say toxic gas or fumes. Jagmarg and Haribhoomi say “lithium gas” without an official source; we do not use that. Lack of oxygen has not been ruled in or out
- Time of death: During treatment at Park Hospital (most reports); already dead when pulled out (ETV Bharat); declared dead at a nearby hospital (UNI)
- Place: Jail Road, Bhondsi police station area (most reports); Dhumaspur (UNI)
- Time: Around noon (The Tribune); afternoon (others); no exact time of the fall is given
- FIR: Registered under BNS 106 and 3(5) (Times Now Navbharat); a case was registered (UNI, Janta Se Rishta); the FIR was “being registered” on family statements (Amar Ujala)
- Not yet known: The cause of death, the gas, the work being done, whether permits, gas testing, breathing apparatus and a rescue plan were in place, and what the company says
What this case teaches
Tanks, sumps, pits and chambers can hold gas that cannot be seen or smelt, or too little oxygen to breathe, and a person can collapse within a few breaths. This is a pattern we have covered before, for example in the Sola sewage plant sump deaths, the Ujjain hotel waste chamber deaths and the Hosur wastewater tank deaths. In several of these, a second or third person went in to help and was also overcome. Our guide on why rescuers die too in tanks, sumps and wells explains why, and what to do instead.
We do not know whether that happened here, and no report says a colleague entered the tank. What the reports do show is that three people were taken out unconscious and none survived, and that police are looking at the safety arrangements. Until an investigation says otherwise, the cause stays open. For readers who work with tanks or manage people who do, the steps under the safety tab are the ones that matter most.
- Three workers become unconscious in a tank at the Sandhar company site on Jail Road, Bhondsi; reports differ on whether they fell in or had gone down to clean it
- Colleagues pull them out and they are taken to Ekta Hospital in Badshahpur, which refers them to Park Hospital (Times Now Navbharat, Haribhoomi)
- All three die during treatment, according to most reports; ETV Bharat says they were already dead when removed
- Bhondsi police reach the site and the hospital, take the bodies and send them to the Civil Hospital mortuary for post-mortem
- A case is registered against the company management after a complaint of unsafe work (UNI, Janta Se Rishta, ETV Bharat)
- Times Now Navbharat reports the FIR under BNS sections 106 and 3(5); no arrest or company statement is reported
Why consequences escalated
- Three workers died after becoming unconscious in a tank at a Sandhar company site in Gurugram on 11 November 2026.
- Colleagues pulled them out and they were taken to Ekta Hospital and then Park Hospital, where they died, according to most reports.
- Police registered an FIR against the company management on a complaint that the workers were made to enter without safety arrangements.
- No gas, cause of death or reason for the fall has been established.
- No arrest, labour department action or company statement had been reported by 12 November 2026.
Failures and risk multipliers
- No investigator has published a finding. What the reports raise as questions:
- Why the three were in or at the tank, and whether it was a job that needed a permit and a gas test first.
- Whether the air in the tank was tested, the tank ventilated and a trained person kept outside with a rope and a rescue plan.
- Whether breathing apparatus and a harness were available, as police are checking.
- What the tank held and what gas, if any, built up in it.
- These are open questions, not findings of fault.
Actions that reduce risk
- Workers: do not enter a tank, pit, sump or chamber that has not been tested and ventilated and that has no trained person outside. You can refuse a job that has no safety arrangements.
- If someone collapses inside: do not go in after them. Call 112 (or 101 for the fire service) at once, keep others out, and use a rope or a lifting line from outside only if it is safe.
- Employers and contractors: use a written entry permit, test the air before and during work, ventilate, give a harness and lifeline, keep a trained attendant outside, and have breathing apparatus and a rescue plan ready before anyone goes in.
- Authorities: name the gas and the cause of death when known, and publish whether the work was permitted.
- Families and co-workers: keep the post-mortem report and the FIR copy.
