There are often times where people resort to plugging in power extension adapters into another power extension adapter to extend them, because they need more sockets and also to extend the range of power adapters so a particular electric appliance or device can be powered somewhere in the house.

Lets say there is an incident where an electrical device over heats and catches on fire; that power surge may go further down the wire beyond the fuse and burn out all the appliances along the daisy chained network of power adapters and they in turn can set fire and cause serious problems.

Power adapters should only be an extension from the main wall socket once, and the small adapter blocks should not be put in them either because they can overload the adapter; even then it’s probably safer to get the surge protected adapters to protect your electrical devices from random power surges.

If more sockets are required, then you should hire a qualified electrician to tap into the ring main and wire up some more wall sockets in the room you need to provide power to the various devices.
