Customised Horn May Have Caused Coastal Road Tunnel Fire
A car fire in a tunnel in Mumbai might have been caused by a customised horn.
The fire made people scared, and some left their cars to run away.
The tunnel has big fans that helped blow away the smoke.
The fire department said the horn's wires might have been bad and caused the fire.
They also said fire extinguishers in the tunnel are hard to find, so they want to put them where people can see them easily.
The city has also made a list of safety rules for people to follow if there's an emergency in the tunnel.
A customised horn in a Maruti Suzuki Ignis may have caused a fire in the Coastal Road tunnel on July 15.
The fire triggered panic, with motorists abandoning their vehicles and fleeing on foot.
Preliminary findings suggest faulty wiring from the customised horn may have damaged other wiring systems, potentially igniting the fire.
The tunnel's Saccardo ventilation system helped control the smoke with high-velocity winds.
Fire extinguishers in the tunnel are being relocated to be more visible and accessible.
The BMC has issued a 12-point safety protocol for motorists during tunnel emergencies.
