What should I do when the power goes out?
Check whether your neighbors are affected and whether your own breaker has tripped, then report it to your utility. Unplug the aircon, ref and electronics to protect them from surges.

Keep well back (at least 10 metres is a common guide), treat every line as live – especially in floodwater – and never touch it or anything in contact with it. Call your utility's hotline, or 911 if there is danger to life or a fire. Warn others to stay away.
