Gas Leak From a Factory: Rights of Affected Residents

If gas has leaked from a factory near your home, you have a right to medical treatment and records of your exposure, a right to know what leaked and what the emergency plan for your area says, a right to interim relief and full compensation from the company without proving it was careless, and a say in whether the unit is allowed to restart. Relief for victims of hazardous substances can be sought from the Collector under the Public Liability Insurance Act, compensation from the National Green Tribunal within 5 years, and safety directions from the State Board and the district administration.

This guide is for people who live, work or study near the factory: families, shopkeepers, RWAs and village panchayats. It covers what to do in the hours and days after a leak, the information you are entitled to, smaller repeated leaks that never make the news, and how a colony can claim relief and have a say on restart.

The wider law on company liability for accidents is in our guide on chemical leaks and industrial accident compensation. This page belongs to our series that starts with thermal power, accidents and pollution near industry.

The essentials

Gas leaked from a factory near my home. What are my rights?

You have five main rights, and they do not wait for anyone to decide who was at fault. The right to treatment and to proper medical records of your exposure. The right to information about what leaked and what the emergency arrangements for your area are. The right to quick interim relief. The right to full compensation for what you lost. And the right to be heard on whether the factory restarts and on what conditions.

Each right has a forum. Treatment comes through government and private hospitals, and the district administration can be asked to run health camps. Information can be asked of the unit, the State Board, the factory inspectorate and the district administration, by letter and by RTI. Interim relief under the Public Liability Insurance Act is applied for to the Collector. Compensation is claimed before the NGT under sections 15, 17 and 18 of the NGT Act. Restart questions go to the State Board and, if a case is pending, the tribunal.

The company's liability is absolute. A company handling a dangerous gas must pay for the harm a leak causes even if it says a valve failed without warning or a contractor made a mistake. Residents should never accept the argument that because the cause is still being investigated, nothing can be paid yet.

What should residents do after a gas leak?

This is about protecting your claim and your family in the days after the emergency, once you are safe. During the leak itself, follow the instructions of the police, fire service and district officials.

People with no symptoms on day one sometimes develop them later. If that happens, see a doctor and add yourself to the list then. Late symptoms are not a reason to give up on a claim.

Were we supposed to be told about the danger before the leak?

Yes, in many cases. Under the Manufacture, Storage and Import of Hazardous Chemical Rules 1989, made under the Environment (Protection) Act, a unit that handles hazardous chemicals above specified quantities is a major accident hazard installation. It must prepare an on-site emergency plan and take steps to inform people outside the site who are likely to be affected of the hazard and what to do in an emergency. The district administration must prepare an off-site emergency plan covering the area around such units.

The Chemical Accidents (Emergency Planning, Preparedness and Response) Rules 1996 add crisis groups at the central, state, district and local level. The local crisis group, in an industrial area, is meant to include people from the community and to run awareness and mock drills. In most colonies near chemical units, nobody has ever seen a drill or heard of the plan.

Ask for the off-site emergency plan by RTI from the district administration, and ask the State Board or factory inspectorate whether the unit is a major accident hazard installation. If the plan does not exist, was never updated, or was never shared, that failure is itself a ground before the tribunal, and it is something an RWA can press on even when there has been no leak at all.

Which gas leaks happen most near homes, and who deals with them?

These are general descriptions to help you report accurately. Do not try to identify a gas by smelling for it; leave the area and tell officials what you noticed.

Whichever gas it is, report it as a leak, give the time and place, and say who was affected. Officials can identify the substance from the unit's records and from sampling.

We feel fine now. Why bother with doctors and records?

Because the effects of some gases show up later, and because a compensation claim without medical records is very hard to prove. A doctor's note made the day after the leak, saying that you complained of breathlessness after exposure to gas from a named factory, is worth more than any number of statements made a year later.

Ask the district administration and the health department to run health camps in the affected area and to keep a register of everyone examined. In larger leaks, ask for follow-up health surveillance over the coming months, especially for children, pregnant women, older people and anyone with asthma or heart disease. Tribunals have directed health monitoring after serious leaks, and residents can ask for it specifically.

Claims can include future medical costs, not only bills already paid. If a doctor advises continued treatment or periodic tests, keep that advice in writing. It is the basis for asking that the company pay for ongoing care rather than a one-time sum.

There is no big disaster, just regular gas smells at night. Can we act?

Yes, and you should, because repeated small leaks are often how serious accidents begin. A unit that releases gas or vapour every few nights may be venting deliberately to avoid running its controls, may have a failing scrubber, or may have equipment that is leaking slowly. Each of those is a breach of its consent conditions under the Air Act, and some are a safety failure under factory law.

Keep a log for three or four weeks: date, time, duration, what it smelled like, wind direction, who was affected. Note whether the smell comes at the same time each night, which often points to a batch process or a vent being opened. Send the log to the State Board with a request for surprise night inspection and sampling, and copy the factory inspectorate.

Our guide on industrial odour and bad smell complaints covers recurring smells in detail, and our guide on complaining about factory smoke covers visible emissions. If the board does nothing, an NGT application about repeated releases is a dispute under the Air Act and the EP Act, and the tribunal can order a joint inspection and safety checks before anything worse happens.

How do residents claim relief and compensation?

Through two separate routes that work together. If the unit handles a notified hazardous substance above the threshold quantity, which is often the case for gases like chlorine and ammonia, it must carry insurance under the Public Liability Insurance Act 1991 and pay fixed relief to victims without proof of fault. Each affected person applies to the Collector. The amounts are modest, but they are meant to come quickly.

Full compensation is claimed before the NGT. A residents' welfare association, a village panchayat or a victims' committee can apply under section 18 as a representative body, listing every household and its losses. Losses can include treatment and future medical costs, wages and business lost during evacuation and illness, damaged household goods, dead livestock and pets, spoiled crops and garden produce, and the cost of temporary shelter. Our page on environmental cases for communities and RWAs explains how such group claims are organised.

Shopkeepers and people who work in the area but live elsewhere are also affected persons. So are tenants, domestic workers and daily wage earners who lost days of work. They are the people most often left off colony lists, and the RWA should go out of its way to include them.

Can we stop the factory restarting until it is safe?

You can ask, and residents' views are often what makes the authorities insist on proper safety checks. After a serious leak, the State Board can direct closure under section 31A of the Air Act or section 5 of the EP Act, and the factory inspectorate can prohibit operation of the unsafe part. The NGT, if seized of the matter, often directs that the unit not restart without a safety audit and the committee's or the board's approval.

Write to the State Board and the district administration asking that the unit stay closed until an independent safety audit is done, its recommendations implemented, the on-site emergency plan revised and the off-site plan updated and explained to residents. Ask to be informed before any restart and to be given a chance to object. If a restart looks imminent and a case is pending, an urgent application can be made; our guide on interim relief and stay in the NGT explains how.

Be realistic about permanent closure. Units are usually allowed to restart once safety is demonstrated, and tribunals balance the risk against the employment and production involved. Permanent closure or relocation is more likely where the unit is in a residential area against land use rules, keeps having incidents, or cannot be made safe at that site. Asking for strict restart conditions is usually more effective than asking only for closure.

How should an RWA or panchayat organise after a leak?

Advocate B.K. Singh's usual advice to RWAs after a leak is to appoint two or three people to keep the colony's records and to speak with one voice. One master list of affected people, one file of medical papers and photographs, one set of letters to the authorities with diary numbers. Colonies where every family writes separately often end up with contradictory accounts that the company's lawyers use against them.

Hold a meeting early and record its minutes. Agree on what the colony wants: treatment and health monitoring, relief for every affected person, compensation, a safety audit before restart, and a working emergency plan with drills. Write those demands down and send them to the Collector, the State Board and the company.

When he drafts the tribunal application for a colony, the demands in that first letter usually become the prayers in the application, and the master list becomes its annexure. That continuity shows the tribunal that residents have been consistent from the start.

Should we also go to the police?

Yes, if anyone was seriously hurt or killed, or if there are signs that safety was deliberately ignored. Causing death or injury by negligent handling of a dangerous substance is an offence under the Bharatiya Nyaya Sanhita 2023, and the police should register an FIR. Residents are witnesses in that case and should give clear statements.

The criminal case runs separately from relief and compensation. It does not need to finish before the NGT can order payment, and an NGT order does not stop the prosecution. Keep the FIR number and copies of your statements in the colony file.
