Chennai: At least six workers were killed and several others hospitalised after a suspected ammonia gas leak at a seafood export processing unit near Periyapalayam in Tamil Nadu’s Tiruvallur district on Sunday, officials said.
The Tamil Nadu government has ordered an immediate investigation into the incident.
According to police and official sources, the leak occurred at a seafood processing and export facility where a large number of migrant workers were employed. Around 120 workers, including women from Assam, Odisha and Jharkhand, were reportedly inside the factory premises when the incident took place.
Authorities said the suspected ammonia leak originated from the unit’s refrigeration or processing system and rapidly spread through parts of the facility. Workers exposed to the gas began suffering from severe breathing difficulties, dizziness and irritation. Some victims reportedly experienced bleeding from the mouth and nose, indicating the seriousness of the exposure.
Panic spread across the premises as workers rushed out of the facility seeking safety, while several others collapsed after inhaling the toxic gas.
Emergency response teams, police personnel and local authorities reached the spot and began rescue operations. The affected workers were initially shifted to nearby private hospitals for emergency treatment.
Police sources had earlier confirmed that one worker died while undergoing treatment. However, as rescue and medical efforts continued, the death toll increased to at least six.
Several others remain in critical condition and are receiving intensive medical care. Doctors treating the victims said many suffered severe respiratory complications due to ammonia gas inhalation.
Workers requiring advanced treatment were later shifted to the Government Stanley Medical College Hospital in Chennai.
Chief Minister C. Joseph Vijay expressed concern over the incident and directed officials to provide all necessary medical assistance to the affected workers. He also ordered the formation of a three-member inquiry committee to investigate the circumstances that led to the leak.
The Chief Minister instructed the panel to conduct an immediate inspection and submit a detailed report within 24 hours. The investigation will examine safety protocols, maintenance procedures and possible lapses at the facility.
Police have registered a case, and further investigation is underway. Officials are also assessing whether any violations of industrial safety regulations contributed to the disaster.
