Electrical Frequently Asked Questions and Knowledge(2)

  1. What are the main causes of electric shock?

Statistics show that the main causes of electrocution accidents are the following:

(1) Lack of electrical safety knowledge, flying a kite near high-voltage lines, climbing high-voltage poles and gnawing the bird's nest; after low-voltage overhead lines are disconnected, they will continue to use their hands to pick up the fire line; the night-time electrified wiring hand touches live bodies; Plastic cover cutter.

(2) Violation of operating procedures, electrified connection to lines or electrical equipment without taking necessary safety measures; touching damaged equipment or wires; mischarging live equipment; lighting fixtures with electricity, repairing power tools with electricity, and electrifying mobile electrical equipment; Wet hand bulbs and so on.

(3) The equipment is unqualified, the safety distance is not enough; the grounding resistance of the second-wire system is too large; the grounding wire is unqualified or the grounding wire is disconnected; the insulation destruction conductor is exposed to the outside.

(4) The equipment is in disrepair, the wind blows off the circuit or the pole is not repaired in time; the bakelite damage of the rubber cover switch is not changed in time; the motor wire is broken and the shell is charged for a long time; the porcelain bottle is destroyed and the phase wire and the pull wire are shorted. The device housing is charged.

(5) For other accidental reasons, the nighttime walking touches live conductors that have fallen off the ground.

  2. What rescue measures should be taken when an electric shock occurs?

In the event of an electric shock, while ensuring the safety of the ambulance itself, it is necessary to first try to get the electric shocker out of the power quickly, and then perform the following repair work.

(1) Untighten tight clothing that prevents the electric shocker from breathing.

(2) Check the mouth of the person who has received the electric shock and clean up the mucus in the mouth. If there is any denture, remove it.

(3) Immediately on-site rescue, such as respiratory arrest, using mouth-to-mouth artificial respiration rescue, if the heart stops beating or irregular tremors, artificial chest compression can be rescued. It must not be interrupted without reason.

If a second person is present in addition to the rescuer at the scene, the following work should also be carried out immediately:

1) Provide tools and equipment for first aid.

2) Dismiss the casual staff at the scene.

3) Keep enough lighting on site and maintain air circulation.

4) Report to the leader and ask the doctor to come to the rescue.

Experimental studies and statistics show that 90% of people can be saved if treatment is started from 1 minute after an electric shock, and only 10% of them are saved if they are rescued from 6 minutes after an electric shock, and emergency rescue is started 12 minutes after an electric shock. The possibility of survival is minimal. Therefore, when someone is found to have an electric shock, they should fight against the seconds and use all possible methods.
