It was a disaster waiting to happen
The tragedy has shown establishments aren't serious about fire safety. Though the hotel had a fire license, it flouted several rules. The hotel had a rooftop restaurant and a bar in the basement.
Apart from this, the narrow emergency exit was also locked, claimed reports. Moreover, sealed windows made rescue difficult.
Furthermore, the staff wasn't trained in handling firefighting equipment.
Notably, firefighters couldn't start operation for hours
The location of the hotel also increased the problems of firefighters. Though they received the first call at 4:30 AM, the fire came under control only at 7 AM as congestion in the area made it impossible for them to access the hotel.
Notably, the hotel's general manager, Rajender, and manager, Vikas have been arrested by Delhi police.
But the owner is at large.
