A fire broke out in the ground-floor meter room of Amar Mehal Building in Wagle Estate, Thane West, early Sunday, gutting three meter boxes.
Meter room fires can cut power to an entire building and spread quickly in older structures. Most metro residents live in shared or multi-storey buildings where one shared meter room serves everyone.
Check your building's meter room for frayed wiring or overloaded boxes and report issues to your society or the local fire brigade.
