The financial capital has been hit by a string of fire incidents in the last fortnight.
The deadliest of them was on December 29 when a devastating inferno killed 14 people at an upscale pub in the Kamala Mills Compound.
On January 4, four persons, including two children, were killed and five others seriously injured after an upper floor of a residential building in suburban Marol caught fire.
A 20-year-old man, who worked for a television serial production unit, was killed in a fire at the Cine Vista film studio in suburban Kanjurmarg on January 6.
Yesterday, a fire broke out is the sessions court building in south Mumbai in which some official records were gutted.
Earlier on December 18, 12 labourers were killed in a massive blaze at a snack-making unit in Saki Naka-Kurla.
As the metropolis battles frequent blazes, the fire department urged people and commercial establishments to take preventive measures to avoid such tragedies.
"Safety measures are a must to avoid such incidents. Apart from taking preventive steps, people should be alert and immediately inform the department about such incidents," said Deputy Chief Fire Officer Kailash Hivrale.
People should keep a watch on electrical wiring in residential buildings and commercial outlets, he said.
Meanwhile, BJP Member of Parliament Kirit Somaiya visited three film and TV studios after the fire at Cine Vista.
He said these studios, located in Kanjurmarg and Bhandup, don't have proper fire fighting systems in place.
"Today, I visited three film and TV studios and found they don't have fire safety systems in place. I told this to the municipal commissioner and demanded strong action against these studios," said the Mumbai North-East MP.
