Mundathikode Fireworks-Unit Blast, Thrissur, Kerala: 16 to 17 Killed in April 2026; Commission Reports About 7,000 kg Explosives Stored Against 15 kg Permitted

What happened on 21 April 2026

On the afternoon of Tuesday, 21 April 2026, a series of explosions tore through a fireworks manufacturing unit at Mundathikode, near Thrissur in Kerala. Workers there were preparing fireworks for the Thiruvambady side of the Thrissur Pooram, the temple festival that was only days away. The Hindu says the blast came at around 3.30 pm and that locals compared the roar to an earthquake. South First’s day-one report speaks of two powerful blasts within seconds of each other, heard several kilometres away.

The Hindu describes a unit in the Kuttamkulam fields spread over nearly five acres, with eight sheds. Five of them caught fire, three of them holding large quantities of explosive material. Rescue was slow. The unit stood in a large plot next to paddy fields with limited access, repeated blasts kept rescuers back, and earthmovers were brought in to clear a way for fire engines. South First adds that firefighters had to break through a nearby wall to get in. Explosions continued on and off for hours. Windows of nearby houses were shattered, and later court coverage speaks of about 50 houses damaged.

Early counts rose through the week as injured workers died in hospital. The first reports spoke of nine dead; The Hindu’s evening report put it at 13, with around 40 injured, five of them with severe burns and 23 admitted to Government Medical College Hospital, Thrissur. The unit’s licensee suffered severe burns and died in hospital on 24 April, which means he could not give evidence to the later inquiry. We have not named any of the victims.

On 29 April the District Collector told the inquiry commission that 43 people had been present at the site and 27 of them survived (The Hindu). The commission’s chair said that day that 43 people had reportedly been working and storing explosives in three small sheds placed close together, with no firefighting system and no access for emergency vehicles. Officials said the dead were identified from bodies and many recovered body parts, and DNA samples were taken for testing (South First, The Hindu).

Follow-up: the commission’s report, 3 November 2026

On Tuesday, 3 November 2026, 196 days after the blast, the one-member judicial commission headed by retired Justice Ramachandran Nair handed its report to Kerala’s Home Minister. Coverage by The Hindu, The New Indian Express and Deccan Herald (PTI) reports its main findings as follows:

• Storage: the unit was permitted to store 15 kg of explosive material, but those who had taken the fireworks contract had stocked about 7,000 kg there. The New Indian Express puts this at nearly 467 times the limit and says the contractors “allegedly” did so.
• Banned chemical: potassium chlorate, a banned explosive substance, was widely used in making the fireworks. The New Indian Express adds that it is highly sensitive to friction.
• Cause, as the commission found it: friction between chemicals in the high temperature set off a fire, and the fire led to the massive explosion.

The coverage reviewed does not give the report’s recommendations, and the full text was not available. In April the commission’s chair had said the panel would also look at whether fireworks displays can be held safely, and would make recommendations. Nothing in the coverage says yet whether the report will be made public.

Where the reports differ

• Final toll: 16 killed in the coverage of the 3 November report (The Hindu, The New Indian Express, Deccan Herald) and in the commission chair’s April statement of “officially declared” deaths (The Hindu, 29 April). 17 killed in The News Minute’s report of 27 April, which says one more worker died in hospital that day, and in The Hindu’s court coverage from July to September. We say 16 to 17, and use 16 on our map.
• Injured: about 40 on the first day and in the 3 November coverage; over 24 in The Hindu’s later court coverage.
• Early toll: day-one and early reports gave 9, 12, 13 and later higher figures as more people died. The old figures should not be used.
• What set it off: the commission found friction between chemicals in the heat. A survivor told the police he had seen a spark before the explosion (The Hindu, 29 April), and early reports spoke of chemical mixing in summer heat (South First). These are earlier witness and preliminary accounts, and the commission’s finding is the one we put forward.

What happened in court and afterwards

• The Kerala High Court took up the matter on its own, on the basis of news reports. By 28 August the police had filed a chargesheet under the Bharatiya Nyaya Sanhita, the Explosives Act, 1884 and the Explosive Substances Act, 1908. An inquiry by the Additional District Magistrate was also on (The Hindu).
• The Centre and the Deputy Chief Controller of Explosives told the High Court that the unit had more workers than permitted, that fireworks were carried in the open and that the mandatory safety zones between work areas were not kept (The Hindu, 28 August).
• On 23 July the Advocate General told the court that some manufacturers supplied far larger quantities of fireworks for public displays than they were authorised to, without proper storage. The Thrissur police commissioner proposed joint pre-licence inspections, regular safety audits, two wide access roads to every unit, grounding of static charge at shed entrances, training and certification of workers, and heavier penalties (The Hindu).
• The state announced Rs 14 lakh each for the families of the dead in June (The New Indian Express, Deccan Herald). The Prime Minister had announced Rs 2 lakh for the next of kin of each person killed and Rs 50,000 for each injured in the first days after the blast (South First). The state told the High Court in July that compensation had been paid.
• A month after the blast, six survivors living near the site were treated for symptoms like those of post-traumatic stress. Others told The Hindu in September that they had received no help.
• On 30 September The Hindu reported that tests by the State Pollution Control Board found chromium, copper, vanadium and cyanide above permissible limits in the topsoil at the site, with removal of about 1,470 tonnes from about 7,000 square metres recommended. The local Member of Parliament has written that the recommended action has not been taken.
• The two devaswoms decided not to hold their fireworks at this year’s Pooram (The News Minute). A PTI report says rituals went ahead and only one symbolic round of crackers was to be burst.

What is not known

• The commission’s recommendations, and whether the report will be published in full.
• Whether anyone has been arrested, and who exactly is named in the chargesheet. The coverage reviewed does not say.
• What the licence allowed apart from the 15 kg storage figure, and what action the licensing authority has taken since.
• The exact final toll, which sources give as 16 or 17.
• Whether the contaminated soil has since been removed, and whether any additional compensation has been decided.

What this case teaches

The headline figure is the gap: 15 kg permitted, about 7,000 kg stored, according to the commission. When the quantity on site is hundreds of times the licence limit, every distance, shed size and escape plan worked out on paper stops meaning anything. Add friction-sensitive chemicals that are banned for this work, crowded sheds and no road in for the fire engines, and a spark in the afternoon heat can decide the rest. The commission’s chair said the harm was made worse by poor safety measures and that proper precautions might have avoided the accident.

What units, workers, neighbours and festival committees can do

• Licence holders and contractors: keep what is stored on site within the licensed quantity, and never let it build up because a festival order is large. Keep sheds apart as the licence requires, with two wide roads in for fire engines. Do not use banned chemicals such as potassium chlorate. Keep the number of people in a shed to what the licence and the work need.
• Workers: ask what you are working with and how much is stored near you. Know your nearest way out and where to gather away from the sheds. You may refuse a task that has not been made safe, and you can report unsafe storage to the police or the licensing authority, the Petroleum and Explosives Safety Organisation (PESO).
• Festival committees: do not ask a maker for more than the licence lets them supply or store. The Thrissur police commissioner’s proposal is that committees who do so should face the penalty for abetment.
• Neighbours: if there is a blast, move well away and keep others away. More explosions can follow. Do not touch debris or burnt material, and call 112. Ask your panchayat or the District Collector for soil and water testing if a site has burnt, and for counselling if you are struggling afterwards.
• Everyone: save the emergency numbers on your phone. Emergency numbers in India tells you which to call, and our guide to festival crowds covers staying safe at melas and pandals.
