No, it is not. . . . .

Double insulation is often used as an alternative to an earthing lead.
However, if the equipment came from the factory with a third lead, it's there for a reason, even if the components appear to be double insulated.

There are 2 schools of thought on this:
1. Ground electrical devices (most in the US are) then if there is a short to the case, it should go to the ground and blow the fuse.
Problem: If the fuse blows to slow you may die.
2. Double insulate devices so that there is much less chance for you to engage the electrical current:
Problem: If you do engage the electrical current, you may die.
Summation: Neither method is "Idiot" proof. So be careful around electricity.

Usually not. Double insulated means that unless you're stupid and start poking a screwdriver through the casing, its impossible to get a shock.

if working on a high current or high voltage devices then it would be needed. double insulated does not always mean safe.
