Overview

• The leak began at around 9:12 pm on July 23 from a faulty valve on a 3,000 kg ammonia tank in Mahananda Dairy’s Goregaon (East) refrigeration unit.
• Mumbai Fire Brigade firefighters, police, 108 ambulance services, HAZMAT teams and BMC ward staff rapidly isolated the valve and disconnected the plant’s power supply.
• Responders neutralized escaping ammonia with sealant and high-pressure water lines while transferring roughly 15–20 kg of residual gas to a secure reservoir.
• No injuries or casualties were reported, and plant staff were evacuated as a precaution with the perimeter cordoned off.
• BMC officials have secured the site and launched a probe into the valve malfunction alongside a review of the dairy’s ammonia handling licence.
