Electrical shock
An electrical shock could take place upon touch of a human's body with any source of voltage high enough to induce sufficient electric current through the muscular tissue or hair. The minimum electric current a human being could sense is believed to be approximately 1 mA. The electric current could induce tissue impairment or fibrillation if it is sufficiently high. Death induced by an electrical shock is denoted to as electrocution.
The danger from an electric shock depends on how eminent the electric potential is, how the electric current moved through the body, the individual's overall wellness and how rapidly the victim is cared for.
Dial 911 or your local emergency phone number instantly if any of these signs or symptoms comes about:
- Cardiac arrest
- Heart beat problems (cardiac arrhythmia)
- Respiratory failure
- Muscular tissue pain and muscle contraction
- Seizures
- Numbness and stinging
- Unconsciousness
Whilst holding back for medical assistance, stick to these measures:
1. Look first. Do not come in contact. The victim might still be in touch with the electric supply. Stirring the victim might pass the electric current through you.
2. Switch off the supply of electrical energy if possible. If not, displace the supply outside from you and the victim , using a nonconductive things made of cardboard, plastic or any sort of wood.
3. Check for signs of respiration, cough or apparent movement. If not found, start cardiac resuscitation (CPR) instantly.
4. Prevent shock. Put the victim down in a position that his legs should be higher then the trunk and the head.
Caution
- Do not touch the victim with your hands if he or she's still in contact with the electric current.
- Do not get close to high-potential cables till the supply is switched off. Keep the distance of approximately twenty feet — farther if cables are bouncing and sparking.
- Do not displace a victim with an electric trauma unless the victim is in contiguous risk.
It's strongly suggested that people shouldn't work on endangered live conductors if at all possible. Incase it is not manageable then insulated gloves and instruments should be practiced. If both hands establish contact with surfaces or targets at unequal electric potential, electric current could run through the body from one hand to the second hand. This could guide the electric current through the heart. Likewise, if the electric current is from one hand to the foot, substantial electric current will probably flow through the heart. An alternative to employing insulated instruments is to keep apart the operator from ground, so that there's no conductive route from the live conductor, through the operator's physical structure, to ground. This technique is applied for working on live high-potential overhead power lines.
