On what is being touted as India's
largest positive-pressure ventilator, a 60-inch fan produces 2,000 revolutions
a min, releases mist to enable firemen to get to source of fire
Intense heat of 850 degrees kept
firefighters from entering the building when fire broke out at Manan Motors on
Vijay Crossroads recently.
When several attempts failed, they
brought out the big gun a positive-pressure ventilator with a 60-inch fan
that was so strong that it blew away smoke, enabling firefighters to reach the
source of fire and extinguish it. Ahmedabad Fire and Emergency Service
officials claim it is India's largest blower fan one they have built out of
scrap.
Referring to the Vijay Crossroad
fire, Chief Fire Officer (Ahmedabad) Mehernosh Dastur said, “It was a massive
fire breakout. The building contained several combustible items like car
battery, LPG cylinder, CNG containers, and tyres. “However, by using the
ventilator, we were able to reach the main source of fire within an hour. Had
we failed to do so there would have been massive damage.” Dastur said that his
team made the blower fan from waste. “We used scrap like old engine, gears,
propellers and a fan (the biggest in India) which was originally part of an air
boat. The fan is made of stainless steel and has the capacity of producing
2,000 revolutions per minute,” he added. The most important thing about the
ventilator is that it not only clears smoke but also makes cools the atmosphere
which facilities firefighters to handle the fire in a better way.
“We can extinguish fire in the
remotest corner where water pipelines cannot reach,” said Dastur.
The machine also releases mist.
“If we can project mist along with the strong winds, it will become easier and
faster to bring the fire under control and lessen damage,” he said.
