The workers complained of nausea and vomiting at a plant in the Atchyutapuram district of the southern state of Andhra Pradesh on Tuesday night.
No deaths had been reported and the situation was under control on Wednesday, broadcaster India Today said.
Around 3,500 people living around the plant operated by Union Carbide died in the days that followed the leak. People continue to suffer the effects of it to this day.
Children are still born disfigured, with webbed feet and hands, and stunted growth because of the gas that affected their mothers.
