.. . Would 1,500VDC with 6mA capability flowing through one arm and out the other be considered lethal? At one time, I knew how much current was considered lethal, but have forgotten. No. It is actually quite hard to kill yourself with electrical shocks. There are tons easier and more likely things to die from in everyday life. 60Hz AC is most dangerous in the range of 100 to 300 mA. Current in that range sometimes causes ventricular fibrillation, whereas currents above that usually cause the heart to temporarily contract and protect itself. Very high currents, however, can dissipate lots of power in your organs and cook them, leading to a painful death if nothing stops the electrocution for several minutes. High frequency AC (like many kilohertz and beyond) should be less dangerous since it will be bound by "skin effect" and not penetrate as far into your chest cavity. DC is considerably safer than 60Hz AC, and I've read some estimates saying you need 4 times as much current to die from DC shocks. I don't know if I believe that though; I suspect there are too few cases to draw significant statistical conclusions. As I understand it (and I may be wrong here), DC is safer than AC because it doesn't cause ventricular fibrillation, so death by these shocks occur from organ damage and falling off ladders and things.

Actually, they ARE supposed to be conductive- at least to the tune of about
a megohm. In any operation that is serious about antistatic procedures, the mats, wrist straps, and other equipment are to be tested periodically. Most testers show if a mat reads open right away. If you have mats or other equipment that read open, then you have found defective hardware. Trash it. Cheers! Chip Shults My robotics, space and CGI web page - http://home.cfl.rr.com/aichip |

I recall having read that AC is considerably more dangerous, for the
reason that Howard stated. Furthermore, 60 Hz is just about the worst frequency. This was determined by executing dogs in less enlightened times. I've also read that Edison created and promoted the electric chair, which was run from AC, to dramatize the danger of AC over DC. He had a big investment in DC distribution systems and equipment, while Westinghouse was promoting AC power distribution.

Actually, I should have said a megohm for a ground strap and 10 megohms or

An acquaintance was working on some plumbing Saturday in one of
several houses under construction in a new subdivision in Albuquerque (New Mexico), and there was a lightning strike into another of the houses, a few hundred feet away. He told me he got knocked flat and so did his helper. Albq is, as many will know, in high desert country, and the ground is *anything* but wet, so buried pipes aren't particularly useful as earth ground. This is a pretty good illustration of that. -- Mike Andrews Tired old sysadmin since 1964 |
