NEW DELHI, Sept. 12 (Xinhua) -- A firefighter was injured when dousing a massive fire at an industrial unit in India's financial capital Mumbai on Wednesday, officials said.

The blaze occurred in Santacruz Electronics Export Processing Zone (SEEPZ) industrial area at Marol in Andheri area of Mumbai.

"Only one firefighter sustained injuries while dousing the flames, while those inside were evacuated on time," a fire official said.

The injured firefighter has been hospitalized, he added.

"A probe has been ordered into the incident. We will book the owner of the industrial unit if any negligence is found on his part," the official said.

Fires are common in Indian residential buildings and industrial houses due to the lack of regards for basic fire safety norms and absence of proper firefighting equipment.
