Noida, Sept. 2 -- A fire broke out at a three-storey factory that makes orthopaedic equipment in Noida Sector 7, E Block, on Monday morning, fire officials said, adding that no casualties were reported. The factory was shut at the time of the incident. Fire officials said prima facie a short circuit is suspected to have triggered the fire but an investigation is on to ascertain the exact cause. At 3.53am, the fire control room received a call about the fire. "Six fire tenders were rushed to the spot and the fire was controlled after two hours. It broke out on the ground and first floors of a three-storey building. Investigation revealed the factory made orthopedic materials like rehabilitation aids and prosthetics," said Pradeep Kumar Chaubey, CFO Gautam Budh Nagar. Officials said that the building is used for both commercial and residential purposes. The ground floor is occupied by the orthopaedic factory, while the top floor is used by the house owner, an elderly couple. "Early Monday morning, when the house owner woke up and found smoke was billowing out of the ground floor factory, he, along with his wife, vacated the building and alerted the fire control room," said an official, requesting anonymity, adding that ground floor was packed with orthopedic materials due to which fire department encountered difficulty in controlling the flames. Firefighters entered the factory wearing breathing apparatus (BA sets) and used hose pipes to reach the fire spot. No case has been registered and further investigation is underway. The factory is registered as "Gupta Ortho Aids," owned by RK Gupta. Gupta told HT that his elder brother, Shubhash Garg, has lived on the upper floor since the 1990s....
