First, the basic knowledge of electric shock accidents
1, definition: refers to the injury or death of human body when it comes into contact with charged body.
2. Harmfulness: Electric shock may lead to serious consequences such as cardiac arrest, respiratory arrest, nervous system damage, and even death.
3. Reason:
(1) The erection of power supply lines is not standardized, such as the erection of temporary emergency lines is too low; Power lines and telephone lines * * * use a pole, which has been around for a long time. When it's windy and rainy, people get an electric shock when they answer the phone.
(2) The electrical equipment is damaged or unqualified, the light switch and lamp holder for daily lighting are damaged, and the socket cover is damaged, which makes it easy for children to get an electric shock when touching or moving with their hands; Electrical equipment such as motors and variable musical instruments are not overhauled, and grounding wires are not installed on the iron shell. The insulation layer of the coil is damaged, the iron shell is charged, and people get an electric shock when they touch it.
(3) The household wiring is not standardized, and the power supply incoming line, temporary wiring and electrical equipment are not provided with separate switches and safety lines, so the power supply cannot be cut off immediately after an accident.
(4) Failing to comply with safety regulations, blindly and foolishly repairing and installing lights and electrical appliances without damaging switches and brake boxes; When rescuing people who get an electric shock, it is not necessary to connect wires with insulating materials, but to directly pull the wounded by hand, thus making the rescuer get an electric shock.
Second, the prevention measures of electric shock accident
1. Equipment maintenance: check the equipment regularly and replace the aged or damaged parts in time.
2. Equipment grounding: ensure that the equipment is well grounded to avoid leakage.
3. Safety operation procedures: strict safety operation procedures are formulated, and employees must operate according to the procedures.
4. Staff training: training the staff engaged in electrical work to improve their safety awareness and skills.
Third, the emergency treatment method of electric shock accident
1. Cut off the power supply: First, cut off the power supply immediately to avoid further electric shock.
2. First-aid measures: First-aid measures such as cardiopulmonary resuscitation were taken for the victims and sent to the hospital for treatment in time.
3. Ask for help: Ask the relevant departments for help and seek professional assistance.
