Actually just to clarifier my nerdiness, its not the volts you need to worry about. Volts (the pressure) is required to create electrical flow (amps). Its the amps thatll kill ya. I believe 1 amp can kill a human. I have been zapped many times by automotive ignition systems, anywhere from 6,000 to 50,000 volts, but am still here today because the amperage is so low. There is only 110 volts in a wall socket but enough amps waitin to fry you like canadian bacon well-done. Either way dont mess with a crt unless you know what yer doin.
