Check whether metal grounded or not


Hi All,
My unit is using carpet and timber floorboard (in kitchen area), my wall is also using plaster board.
Most of the time I build computer for my friends.

Now, when dealing with small delicate computer parts, I need to worry of static electric shock which might 'fry' the parts and make it unusable.

So, I purchased anti-static mattress + wrist that I can attach to myself.

Now the concern I have is, as I have no fixed metal attached to the ground apart from my heater.

Is there any way to check whether metal attached to the ground or not?

Or, do you have any other suggestion to make myself grounded during computer setup process?

Thanks

In the US a modern 120V circuit will have a ground. Anything plugged in will be grounded (if it has a ground pin on the plug).

If you have a metallic zipstrip/surge suppressor, you could ground to it's metal case using an existing screw or carefully install a self tapping screw.

Your computer will also be grounded and will have a few screws that would be easy to attach a ground wire to.

A voltage tester will read 120 volts from hot to anything grounded.

Thanks for your reply.
As I'm in Australia, our 240v plug slightly different with USA one,
we have 3 plugs (as indicated at the following picture)

Now, As far as I know the two tops are the HOT plugs? and the bottom one is the ground?
As most of Australian power board don't exposed their HOTS and GROUND sockets (see example here), I'm not sure where I can attach the anti-static alligator bit to the ground

Hope this explains what I want to achieve

Thanks heaps!
