More than 50 women have suddenly fallen ill after a suspected gas leak at a clothes factory.
A number of workers were rushed to hospital following the incident, which took place at the apparel manufacturing unit in the Brandix Special Economic Zone (SEZ) near the Indian city of Visakhapatnam.
Others received first aid at a local medical centre, reported The Indian Express citing local police sources.
Some of the victims reported difficulty breathing, while others experienced nausea and vomiting.
A tweet from the ANI news agency read: "The gas leak reportedly took place on the premises of Brandix.
"At present 53 patients are admitted here. Most of the patients complained of difficulty in breathing, nausea, vomiting,"
Brandix India Apparel later released a statement saying they had received complaints of an "unpleasant odour" from employees, adding: “The safety and well-being of our associates is of utmost importance and we have evacuated all of them. The affected associates are in a stable condition,”
A similar incident at the same location on June 3 also left 200 women workers unconscious, according to a local report.
An ammonia gas leak from from a nearby plant was then suspected of causing the incident.
Human exposure to high levels of ammonia in the air can cause immediate and painful burning of the nose, throat and respiratory tract.
Back in June, horrific footage from Jordan captured the moment toxic gas engulfed an entire port.
A 25 tonne chlorine tank exploded with yellow-coloured gas at a dock in the Aqaba port, killing ten and injuring at least 251 workers - as dock workers tried desperately to flee the toxic scene.
The chlorine gas was being exported to Djibouti but a leak was caused during transportation, according to officials.
Specialised teams, including evacuation planes, were deployed by the Civil Defence Service to contain the leak, according to Public Security Directorate.
