Recent tragedy: In Queens, New York, a roofer was replacing shingles on a two-story house last fall when his aluminum ladder struck a live wire and 120 volts surged through his body. William Barrett, just 27 years old and an expectant father, went into cardiac arrest and fell from the ladder. He was later pronounced dead, though it was unclear if it was from the shock or the fall. Co-workers witnessed the incident, one telling the New York Daily News, "we were looking right at him… we just couldn't do anything."
