wrong again. 50 mA causes no more than discomfort. it requires a sustained 100-200 mA to induce ventricular fibrillation, and over 200 mA to halt breathing and pose a serious risk of death (quoted directly from a medical text). please scroll up to read a knowledgable contribution to this thread from Jeff Walther. i might add that i too, as a young apprentice to an electrician, once touched a hot 220 feed (unfused, directly from the powerlines) and even though it knocked me to the floor 15 feet from where i was standing, i neither needed nor received any medical attention, and i am still here to tell you that you don't know what you're talking about when it comes to the dangers of electric shocks. furthermore, the total amount of charge stored in a CRT is minimal, and is completely discharged in a millisecond or so. hardly a sustained electrocution. i suppose if someone were soaking wet and standing on their naked left foot on a grounded metal plate connected by metal rods sunk to the level of the water table, and they discharged a just unplugged CRT thru their left hand forcing the momentary current to pass direct thru their heart, there might be a small risk of inducing ventricular fibrillation (which is still not necessarily fatal). the absurdly over-cautious posts in this thread simply confirm the old adage that there is nothing more dangerous than a little bit of knowledge. not even electricity. besides, as the original poster has just added, replacing the HD in an eMac is simple, and unless someone is a complete idiot (in which case a highly improbable death by electric shock would just be one small victory for evolution), it is easily done without ever going near the CRT. -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
