Electrical safety is essential for enjoying amateur radio. Many people are killed each year by coming in contact with ordinary power line conductors--the most hazardous aspect of model rocketry is people attempting to retrieve their rockets from powerlines.  Hams face a similar problem--the installation of antennas can put us in harm's way--way too close to dangerous power lines.  Similarly, much of our equipment is powered by electrical mains--one can't be too careful when opening up equipment for servicing.
