Why is 50 Hz current hazardous?

What is important is the voltage (and the source impedance). A 230v 50Hz supply with a moderate to low source impedance is dangerous as it can drive enough electricity through your body to disrupt the heart rhythm.

What are the two major hazards of electricity?

There are two known hazards of electricity—thermal and shock. A thermal hazard is one where excessive electric power causes undesired thermal effects, such as starting a fire in the wall of a house. A shock hazard occurs when electric current passes through a person.
