The Mumbai fire brigade will submit its report on the fire at Kalbadevi’s Gokul Nivas next week.
While the report was to be submitted on Friday, the department has sent a letter to inquiry panel, asking for one more week to file the results of the investigations.
The exact cause of the fire is yet to be ascertained, but the preliminary probe has revealed the fire spread because the building had wooden scaffoldings, and many of the floors had stored LPG cylinders and chemicals.
The investigation report was initially supposed to detail the cause of the fire, but it will now include aspects such as the problems faced during the rescue work, suggestions for a standard operating procedure for fire-fighting operations, and the geographical features of the area.
A senior fire official said that after analysing the sequence of events during the fire, they have come to a conclusion that chief fire officer Sunil Nesirkar and his team were standing outside the building when they were trapped. A part of the building collapsed horizontally and Nesirkar and the other officers got buried in the debris.
“We will be able to submit the inquiry report only be next week. We are taking the help of forensic experts to ascertain what happened. Preliminary investigation has shown the fire spread because of inflammable material such as LPG cylinder, and chemical thinners stored by the residents,” said PS Rahangdale, deputy chief fire officer.
Three fire officers were killed in the fire at the four-storey Gokul Niwas building in Kalbadevi on May 9. While assistant divisional fire officer SW Rane and station officer MM Desai died on the spot, deputy chief fire officer SG Amin passed away on Friday.
