There are various ways of electrocution, and one of the classifications categorizes electrocution into single-phase electrocution, two-phase electrocution and step-voltage electrocution. But in reality there are other ways of electrocution.
1. Single-phase electrocution: the human body contacts the electrified object of one pole electrocution.
2. two-phase electrocution: the human body touches the two poles of the electrified body electrocuted.
3. Step voltage electrocution: the person enters the potential uneven electric field, the potential between the two feet is different and caused by the electrocution.
In reality, it is common to see single-phase and two-phase electrocution methods, mostly caused by defects in electric equipment, and after the accident, the patient’s injury is heavier. The degree of patient injury is related to the current strength, type, voltage level, duration of electrocution, human body resistance, and current pathway.
When the patient is found electrocuted, first cut off the power supply, and do a good job on-site treatment. Cut off the power supply due to pay attention to strict compliance with the principle of insulation, thunderstorms may make the insulation items fail, in the step across the high voltage electrocution, should try to cut off the route 20m away. When there is an electrocution patient, should immediately seek medical attention.
