A fire broke out at a sweater factory housed in a high-rise commercial building in Signboard area of the city, leaving five workers who attempted to douse the blaze injured on Tuesday morning.
Joydebpur Fire Service Station officer Hasibur Rahman said the fire erupted in Matrix Sweater Factory on the sixth floor of the building in the area around 7:30am.
No major casualties are feared as the fire began before the morning shift started for the day.
Ten firefighting units from Joydebpur and Tongi fire service stations rushed in and six of them were working to douse the blaze, but the fire fighters said their efforts to tame the inferno were being hampered because of lack of adequate water.
At least five workers suffered burn injuries as they tried to douse the fire.
The reason behind the fire could not be immediately ascertained.
Fire accidents have been a major concern for the country's burgeoning garment industry, which annually earns about $25 billion from exports mainly to the United States and Europe, since a devastating fire at Tazreen Fashions Limited at Ashulia industrial belt that had killed at least 117 workers and injured about 200 others in 2012.
But the industry insiders and global partners have said the country's garment industry has improved to a great extent in recent years in its fire safety standard following the Tazreen accident and the collapse of the Rana Plaza in 2013 that killed more than 1100 people.
