"Safe Use of Electricity" Electric Power and Electric Power PPT Courseware 4

What factors are related to the hazards of electric shock?

The danger of electric current to the human body during electric shock is related to ________, ________ and other factors.

Learn about various voltage values

Safety voltage for human body: less than 36 V

Household circuit voltage: 220 V

Power circuit voltage: 380 V

High voltage transmission voltage: 105 V

To ensure safe use of electricity:

First, avoid direct contact with live wires.

Also note that objects that were originally uncharged become charged or objects that were originally insulating become conductors.

"Four Don's" must be done for safe use of electricity

No contact with low-voltage charged objects

Do not approach high-voltage charged objects

Do not use electrical appliances when getting wet

No damage to the insulation layer

Measures in case of electric shock:

Turn off the power switch immediately and cut off the circuit

Or use insulators to separate the wires and rescue them on site
