Socket overload

Is it safe to use a 4 gang extension lead plugged into a 5 gang extension lead from one socket. The extension leads between them have plugged in:

2 pcs
2 monitors
1 lamp
2 fans
1 mobile phone charger

this is in the workplace.

I say the main socket is overloaded but person who has attached second ext. lead to save uplugging lamp/fan etc. to charge phone says it's okay.

    Why do you think that the main socket is overloaded? Each appliance including the extension leads has their own fuse to prevent overloading. The socket that everything is plugged into can supply 3kW, so it's not likely to be overloaded by those appliances.

    its probably not overloaded just very very messy, ive done much worse things with power tools which use a lot more juice.

    Because extension lead thing no.1 gets very warm to the touch and because in a previous office when we had our electrical safety checks where they sticker everything we were told we were not allowed to have an extension cable on an extension cable.

    They are left plugged in 24/7 as it's impossible to get at socket to switch off overnight and weekends.

    The extension lead could have a loose connection or it may have come from the £ shop but not having an extension cable on an extension cable is a local rule, not a technical rule. What matters is that the total wattage should be less that 3kW. What is the total wattage of your connected devices?

    supplied by employer so doubt poundshop. It probably is about 20 years old though! It had a sticker on it recently to it passed the electrical testing they do but the other extension lead wasn't plugged in then.

    I asked my OH about this and he said he wouldn't do it in the home or with his power tools but that is because he doesn't want to take any risks with us his family. He said he couldn't give a !!!! if it happens in work though! Oh well at least he love us:)

    Absolutely no idea and googling didn't give me much more info. :o

    It's not dangerous as such (the fuses should prevent problems) but Health & safety would have a fit if they found out.
    These kind of things do have a tendency to overheat or short out and take loads of other things with them.

    What IS dangerous is using an extension cable that is coiled on a reel. I've seen one melt!
    Try saying "I have under-a-pound in my wallet" and listen to people react!

    My OH is always telling me off for not properly unwinding the hoover lead and using it with knots in!:o

    As a general rule, you shouldn't plug an extension into an extension. What you should get is a bigger extension lead, with 8 or 10 sockets. The Fire Service wouldn't be too keen on what you're doing either!
