This kind of issue is easily avoided by touching ground (like the case of a PC connected to a grounded outlet) before handling hardware.
I always touch my PC case before and while handling PC parts.
If you are 0v, and the device is 0v, then there is no discharge and nothing to worry about.
If you are 0v, and the device is ?v, then the device will discharge to you - that can kill it.
If you are ?v, and the device is 0v, then you will discharge to the device - that can kill it.
If you are ?v, and the device is ?v, then... you're gambling but odds are a discharge will kill it.
Generally speaking, PC parts should always be 0v either by being grounded in a PC case, or by being 0v when placed into an antistatic container. So, generally speaking, touching ground to reset yourself to 0v makes contact safe. But, if the device is not 0v then you have a problem.
In my experience problems emerge when the PC part arrives charged to ?v, and putting bubble wrap through UK postal systems seems to charge it to ?v.
