Incident overview
An explosion at a small firecracker manufacturing unit in Champahati, South 24 Parganas district of West Bengal, killed one worker and left three others in critical condition. The incident occurred while firecrackers were being produced for wedding celebrations, and a police investigation into the exact cause is ongoing.
Location and facility details
The incident took place in a firecracker factory located in Champahati under Baruipur police jurisdiction in South 24 Parganas, West Bengal. The unit operated in a mixed-use area close to residential houses, which were also damaged by the force of the blast.
Incident sequence and response
The explosion occurred at around 1 pm local time while work was underway inside the factory. The blast triggered a fire that gutted part of the building and even a nearby large tree, prompting the deployment of multiple fire tenders to bring the situation under control. Local residents reported that the explosion was sudden and so intense that a factory wall collapsed and the asbestos roof was blown off. Workers who sustained burns were quickly evacuated and admitted to hospitals in Baruipur and Kolkata for emergency treatment.
Casualties and evacuation
Four workers suffered severe burn injuries in the explosion, with one victim, 70‑year‑old Gouhari Ganguly, later succumbing to approximately 80% burn injuries in hospital. The remaining three injured workers – identified as Gour Gangopadhyay, Kishan Mandal and Rahul Mandal – remain in critical condition and are reportedly fighting for their lives. One of the survivors is said to have suffered burns over 90% of the body surface area.
Additional context
Police stated that the factory owner is absconding, and a formal probe has been initiated to determine licensing status, compliance, and the root cause of the blast. A preliminary assessment suggests the explosion may have been triggered by unskilled workers mishandling explosive materials used in firecracker production. Authorities also noted that a similar explosion in another firecracker unit in Champahati in December 2024 resulted in three fatalities, highlighting a pattern of recurring incidents in the area.
Safety implications
The incident underscores critical deficiencies in process safety, competency management, and supervision in small‑scale pyrotechnics manufacturing. Locating such facilities within or adjacent to residential areas significantly increases off‑site risk, as evidenced by damage to nearby houses and infrastructure from the blast overpressure. The case reinforces the need for strict enforcement of licensing, segregation of hazardous operations, worker training on explosive handling, and routine inspections of firecracker units, particularly in regions with a history of similar incidents.
