A fierce fire that broke out in a chemical factory in the SITE area was brought under control after 30 hours. The building, almost completely destroyed, was declared dangerous by the concerned authorities on Monday. The massive fire broke out at private chemical factory in Gul Bai on Saturday at around 12:30 am engulfing two adjacent buildings. Fire tenders from across the city were called in to douse the blaze. More than 15 fire tenders, two snorkels and two fire tankers were involved in extinguishing the inferno for more than 3 hours but the fierce fire continued to engulf the entire five-storey building. Later, the rescue operations were halted due to fears that the dilapidated building could collapse at any time. Fire department officials said it was difficult to extinguish the fire because of chemicals and plastic materials present inside the factory. Teams from Pakistan Air Force and Karachi Port also took part in the rescue operation. Fire-fighting officials declared the fire as a third degree inferno. No loss of life has been reported in the incident.
