Suddenly, we saw through the window huge black smokes bellowing up and noticed a fire at our building,” said she.”Instantly, I along with other colleagues got out of the office and rushed to the staircase. We heard people screaming and saw smoke filling up the staircase,” she added.Firefighters on ladders work to extinguish a blaze in an office building in Dhaka on 28 March 2019.

But a little later, it was impossible to stay there because of the smoke,” she went on saying.Parvin and some of her colleagues ran towards the rooftop as it was impossible to get down through the stairs due to the huge dark smoke. After reaching the rooftop, they jumped to the adjacent building, Ahmed Tower, and got down to the ground.Parvin narrated she saw some people jumping off the building breaking open the windowpanes. “Too late to make it to the rooftop for an easier escape, they tried to escape through the windows of the building and some of them fell down.”Fire breaks out at FR Tower in Banani in the capital on Thursdya afternoon.

But after that, the staircase become too hazy for people to make it through,” she said.Parvin said there were 65 employees on their floor but four of those could not manage to escape. “Later, they were rescued by firefighters around 3:45pm and taken to Apollo Hospitals.”She, however, said there was no emergency fire exit in the 22-storey building that houses dozens of offices. “I’ve been working in this building for around seven years and had the same experience during an earthquake several years back…many panicked people were injured while getting down,” she added.Sushanta Roy, now undergoing treatment at Apollo Hospitals, told UNB, “Thanks to the Almighty that I’m alive. When I got trapped on the 17th floor, I thought it’s over, I wouldn’t survive. We were unable to breathe properly due to suffocation and black smoke.””We broke opened the glass wall and screamed for help. Once, I thought I would jump off the building, but saw several people fell down while climbing down holding cables,” he said.A helicopter carries water to drop on a burning office building as Bangladeshi firefighters on ladders work to extinguish the blaze in Dhaka on 28 March 2019.

After investigation, it was found they summited an improper design without RAJUK’s approval. The building was constructed violating the (original) design.”Firefighters carry a casualty next to a burning office building in Dhaka on 28 March 2019.
