The normal answer is to fit filters with bleeder resistors across the Line-to-Neutral capacitor, which is the main culprit for shocks.
In fact, I would ALWAYS advocate these - having known of several cases where people have picked up unplugged equipment, and then dropped it due to the reaction shock from touching the plug pins. Dropping a 20-30lb unit on you foot hurts - and you do not think very kindly of that EQUIPMENT manufacturer from then on!!

This sometimes means the filter is upstream of the/any mains switch or breaker. In these cases, what can be done to mitigate the shock risk at the equipment plug for those first seconds after removal? We warn our customers at the mains terminals and in the manual, but, still.... ------------------------------------------- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
