A. Power LinesB. WaterC. FiresD. Overturns
Um, caused by operators who get their training on Yahoo Answers? Overturns are more dangerous to others, a couple years ago a crane killed someone in an apartment across the street from where the crane was working, in a city not far from where I live, but the operator survived. However power lines might be more dangerous to the operator since I suspect they happen more often.
Dangerous to whom and exactly what does overturns mean? Operators are most likely to be killed when a tower crane breaks (is this an overturn?) because the operator is several hundred feet up in the air in the cab. Hitting power lines can be risky to the operator if dumb but staying in the cab is likely to be safe (stepping out may kill in touching ground) Overturning a ground based crane is going to hurt someone in the area much of the time.
