Power outage

If anyone is in danger, call for help first. UAE numbers:

What to do now

Check your fuse box first. If neighbours are also dark, report the outage to your utility.
Switch off or unplug appliances and electronics to avoid a surge when power returns.
Keep fridge and freezer doors shut. A closed fridge keeps food safe for about 4 hours.
Use torches rather than candles. If you must use candles, never leave them unattended.
Never run generators, barbecues or camping heaters indoors, in garages or near windows.
Run any generator outside, at least 6 metres (20 feet) from doors, windows and vents.
Never plug a generator into a wall socket. It can harm utility workers.
If a carbon monoxide alarm sounds, get out at once and call emergency services.
